Sub Ohm Vaping Guide

There’s No Place Like Sub-Ohm

Sub ohm vaping is a huge part of the vaping world today, it was only a few years back that this style of vaping was accessible to the DIY coil builders but an increasing number of sub-ohm tank options have since arrived making it easily accessible to all.

So, if you are reading this you are likely asking the question “What is sub ohm vaping?”. This is exactly what we will tell you with our Sub Ohm guide. Read on!

What Is An Ohm?

Just as electrical current is measured in amps or length measured in meters, the measure of resistance of a coil is in ohms, sometimes seen as the symbol Ω.

Most standard replacement heads for mouth to lung (MTL) vape tanks/clearomizers are between 1.2Ω to 2.0Ω. Some vapers now refer to this as ‘plus-ohm’.

The term ‘sub-ohm’ is used when the resistance of a coil measures less than 1 ohm.

The hugely popular Aspire Cleito Pro and other highly rated sub ohm tanks offer the option to use a 0.16-0.5Ω replacement head.aspire cleito pro sub ohm tank review

What Difference Does A Sub-ohm Coil Make?

As the resistance of a coil reduces it allows more electrical current to flow.

Higher current means more energy is getting to the coil, faster. This results in a coil heating up quicker and reaching a higher temperature.

Hotter coils lead to an increase in e-liquid being vaporised which, when combined with an increased airflow, increases the clouds produced as well as the flavour.

Mouth to lung or lung inhale?

One issue you might have with a Sub-Ohm tank is that a lot of them require you to make direct to lung (DTL) inhales.

Learn More: Check out our MTL vs DTL guide for more information.

It is strange initially to get used to since when we smoked we all did mouth to lung inhales.

You do get used to it but if you are the kind of person that doesn’t want to inhale hard on a tank then it may not be for you.

There are Sub-Ohm tanks that let you do both so you can choose your own preference.

One such example is JAC Vapour S22 Tank.

So, I Need A Sub Ohm Tank Then?

No. Most people spend their entire time vaping quite happily in the 1.2-2.0Ω regions with the likes of the Aspire Nautilus 2s and Innokin Endura T18ii.

If you are happy with what you have then there’s little reason to change – but you may wish to explore this type of vaping all the same.

Others seek more ‘hit’ from their vape and an increase in the volume of vapour will lead to an increase in nicotine per puff.

Reducing Your Nicotine For Sub Ohm Vaping

If you have been using mouth to lung vape tanks or e cigarettes then you are likely using a higher nicotine content in your e liquid or nic salts. This could be anywhere from 11mg-20mg (max is 20mg in the UK).

When sub ohm vaping it’s recommended to reduce the percentage of nicotine that’s in your e juice.

This is for the simple fact that sub ohm vaping provides a bigger ‘hit’ when you vape. If you vape 18mg juice MTL then using this for sub ohm vaping will likely be too strong.

For most, sub ohm vaping with high nicotine will be near on unbearable!

I personally vape at 12mg mouth to lung but when sub ohm vaping I reduce my nicotine to 3mg and on occasion 6mg.

So please, just keep this in mind.

If that is what you are looking for then you can also see what our top choices for sub ohm tank are.

E-Liquid: PG / VG Ratios Best Suited For Sub Ohm Vaping

In addition to your nicotine percentage the PG/VG ratio in the e-liquid you use for sub ohm vaping also needs to be taken into account.

Sub Ohm vaping is perfect for higher VG e-liquids due to the larger coil sizes. The higher VG also provides a smoother vapour which is definitely a plus when vaping at a higher wattage.

We have an in depth guide to PG vs VG in e-liquid here

Do I Need A Special Vape Mod To Use A Sub-Ohm Tank On?

Yes, absolutely.

There are a number of different devices. Mainly falling into the following categories:

Mods that have integrated batteries recharge by plugging in a USB cable. Whichever you decide on you need specific cells that can cope with the current a low-ohm coil allows to flow.

One very important thing we will say is if you are going for a mechanical mod you need to have a sound knowledge of battery safety and ohms law. Mech Mods are NOT regulated and can be very dangerous if used incorrectly.

With that in mind, if you are new to vaping we recommend sticking to the regulated variety.

Most entry level Vape pens will not be able to handle the stress and older box mods such as the Eleaf 20W and the MVP 2 will just refuse to work.

These do not work with coils under 1.0 Ohms. Just be sure to double check what resistance coils the sub ohm tank you go for comes with. It has to be said though, the majority of the latest vape mods on the market today cater to the sub ohm vaper.

High current can damage battery cells and lead to accidents or simply fail to work at all. It is important to use the correct battery or device.

What Batteries or Mods Can I Use With a Sub Ohm Tank?

There are simply too many devices on the market now to list them all, but here are some things for you to think about:

Regulated devices (adjustable power)

The first consideration will depend on which size of atomizer you are using. Some people like a flush fitting appearance; others are not too bothered with the atomizer overhanging the mod. The size is usually referred to as diameter with most tanks sitting around 22-25mm.

Many regulated devices will list the lowest ohms they can power – if it doesn’t list it on the mod specification the safest solution is not to use it until you have confirmation it’s safe from the vendor or manufacturer.

All of the main e cig manufacturers produce sub ohm capable mods. Brands such as Aspire, Innokin, Voopoo, Vaporesso and Jacvapour (to name a small selection) are all trusted suppliers that continually produce high quality products. Beginners Guide To Sub Ohm Vaping

Mods using genuine DNA chips in the circuit boards will all be able to handle the demands the atomisers place on them.

Check out our guide and recommended DNA Mods here.

Again, some of the above will only be compatible with 0.5Ohm resistance coils, some will be compatible with resistances down to 0.1 Ohms.

Just be sure to check the mod and the tank, if buying separately, are compatible.

A reminder of what to look for:

  • The coil resistance ie; 0.2Ohm / 0.5ohm
  • What coil resistance the vape mod can handle. This will be in the specs for the mod.

Mechanical Mods

When using these atomisers on mechanical mods the warning is: do not use cheap or counterfeit cells. The other warning is, know 100% what you are doing!

Most Ebay vendors do not purchase their cells directly from companies and there are many clones about. Avoid all cells that have the word ‘fire’ in the name.

It is worth looking at this video about fake cells on Ebay.

The most common cells used by vapers are the Sony VTC5 and Samsung 25R. These cells balance affordability with performance and can perform at 0.5Ω.

Drone BF BatteriesThe universal rule with batteries is: You get what you pay for. We have a separate guide on batteries for sub ohm vaping here.

Sub-Ohm Tanks and Temperature Control

One great advantage of Sub-Ohm tanks is that some of them can be fitted with Nickel (Ni200), Titanium (Ti) and Stainless Steel coils designed for use with Temperature Control devices.

For many people who really don’t want to mess around making Nickel coils for their RDA’s and RTA’s this makes things extremely convenient.

In my experience so far I have to say that the right Sub Ohm tank with a Nickel coil gives an absolutely cracking vape but again this isn’t for everyone.

Find out more with our Temperature Control vaping guide.

Possible Drawbacks

So, you are all fired up and want to take your vaping to another level. But, to do it as safely as possible you need to be aware of the following:

If your wick is not wicking juice fast enough it will dry out quickly due to the low ohms, it is vital that a wick remains moist to avoid dry hits.

This is especially important if you begin to build your own coils and wicks in a rebuildable atomiser. These you will see referred to mainly as RDA’s, RTA’s and RDTA’s.

Dry hits not only taste unpleasant but Dr. Konstantinos Farsalinos is currently carrying out a research study investigating what toxins are produced by coils at elevated temperatures.

Lower ohms leads to a faster current running through the circuit, this will also run your battery cell down faster – an important consideration if you are wanting an all-day vape for work or leisure.

  1. Sorry if I am going to sound dumb. I have just purchased a geekvape solo with the corner is tank. Is this suitable for use with nic salts?

  2. Hi Jonny, Many thanks for the informative and helpful reply about the differences between the Boost and regular sub ohm devices. It certainly helped clear up my confusion over these things, and puts me in the ballpark as to what to try in the Boost.

    So far I have only tried one experiment with the juice. Yesterday I took 1 ml of 8mg 50%VG juice and mixed it with about 1.3ml of glycerin (food grade from the kitchen cupboard). According to an ejuice calculator the resulting mix is approximately 3.5mg/ml nic and 80%VG.

    I tried this concoction, dtl, in the Boost using the 0.4 ohm coil (25W, open airway), and I found that I actually like it. It seemed much less harsh, so it was easy to inhale far larger amounts, though it does start to get a bit warm around 30W. Despite it being fairly thick, there were no obvious problems with the wicking.

    As yet the only other juice I have tried is 12mg 70%VG (via mtl). It was okay, but dtl-ing the home style stuff was a better experience for me. Easier on the throat, and even though it was much lower in nicotine, I got a more satisfying hit from it. And I can now blow cloudlets, which amuses me.

    Next, I would like to try (20 – 40 mg) nic salts for mtl, and low strength salt (3 – 6mg/ml) dtl. Should be interesting (well to me anyway!).


    • Great to hear the experimentation is going well and you’re getting nearer to your preferred vape. Be sure to let us know how you go with the higher nic salt strengths πŸ™‚

  3. A couple of days ago I bought my first vape, a Geekvape Aegis Boost. It comes installed with a 0.4 ohm coil and a spare 0.6 ohm, so I guess technically it is sub ohm. Apart from that the Boost seems to of a somewhat different design to that of a regular sub ohm vape. So Im wondering if I can take advice meant for regular sub ohm vapes and apply it to the GVBoost?

    For instance, I find that I like the dtl method, and I have read that it is possible to use low strength nic salts in a sub ohm vape. Im not a fan of the throat hit, so I thought I would try dtl-ing salts in the Boost. Ive seen forums where sub ohming salts at various strengths etc. is discussed, but Im not sure how relevant that stuff might actually be to the Boost.

    Obviously the nic strength thing could be resolved with a little trial and error. But in general can I regard the Boost as a regular sub ohm vape? Or does it not quite fit that category? The maximum power for the Boost is 40W, but many of the sub ohm devices I have seen go a fair bit higher than that. Airflow might be a factor too, I read that the Boost is a little restricted compared to the more typical sub ohm device. There is an RBA pod available, which I suspect might the device as a whole a bit more sub ohmy. (Eg. I think it might take a lower resistance coil.) But Im new to all this so Im really not sure about any of that!



    • Hi Charlie,

      Good question and it is something that can throw a spanner in the works of how sub ohm vaping is looked at..

      While sub ohm refers, literally, to a coil that is rated under 1.0Ohm. Sub ohm vaping traditionally goes hand in hand with Direct to Lung (DTL) vaping.

      So a true sub ohm/DTL vape experience, currently, is mainly only achieved with a dedicated sub ohm tank.

      Sub ohm tanks offer:

      Higher operating wattages
      Larger airflow
      Larger coils
      Larger cotton surface areas to oak up e-liquid
      Wider bore mouthpiece/drip tip
      The above all offer a true direct to lung vape which is different to a sub ohm vape you would achieve on the boost.

      Sub ohm pod systems ‘generally’ offer:

      Smaller coils
      Smaller airflow
      Smaller surface area for juice to soak in.
      Operate at lower wattage
      Narrower bore drip tip/mouthpiece (Even with the DTL dedicated drip tip)

      The above for me (I am actually vaping the Boost as I write this) offers a more restrictive direct to lung vape than a sub ohm tank would.

      If you were to compare side by side two 0.4oHm coils in say the Boost pod and a standalone sub ohm tank you would see a big size difference.

      We will be adding the Geekvape Boost RBA to the review soon so can see how that performs. While it may improve the DTL experience somewhat the airflow on the device would still be restrictive when compared to a true DTL tank.

      Nic Salts

      I am actually vaping 20mg nic salt in the Boost right now (mainly because I had run out of juice and this was all I had) and have done with both coil and mouthpiece options. I vape this at a low wattage though, generally 11.5W-13.5W. I like a cooler vape generally. If you prefer a warmer, higher wattage vape then it may be too much so keep that in mind.

      As you say though it is all a bit of trial and error!

      Let us know how you go though Charlie.

  4. Hello, I’m new to vaping just bought the wismec predator 228 kit. I’m asking can i use a different brant of replaceable coil to my elabo tank? Can you give me some suggesttions. And can I use a different tank on my predator? Like a smok product etc….

    • Hey Boj,

      Not other brand coils are compatible that I’m aware of.

      There are a number of ‘WS’ Wismec coils that are compatible with the Elabo tank though. Have you tried different coils to see if this gives you something nearer what you are looking for? The WS-M, WS04, WS01, WS02 and WS03 all fit.

      Other than that, yes you can use any other brand of tank on the Predator mod.

  5. Hi,
    I need to replace my tank and mod, and would appreciate any suggestions, I currently have a single cell mod set at 40W with Uwell Crown 3 tank 0.5 coil I use 16mg juice and mtl style vaping

    I have had this set up for over a year now and can highly recommend the crown 3, I still have the original coil in it!!! Been good for 50K puffs!!! I have dropped it 100s of times and it has never broken but now it leaks a lot when juice gets low and mod is worse for wear, racked up 87510 puffs

    I am considering the same tank or maybe the crown 4 with 0.4 coil and vaporesso luxe nano mod, but concerned if battery life will be sufficient

    I have tried many other tanks and they either leak or you have to change the coil every couple of weeks, I see a lot of people rate aspire, but the ones I have tried often need the coil changed and I have had several times burned taste or mouthful of hot fluid, I guess the newer models are better

    Any feedback on the crown 4 or luxe nano appreciated or if you have any better suggestions?


    • Holy shit Mike! A year on one coil! Fair play, I’ve not seen that before πŸ™‚

      What I will say Mike, if you change that coil it will be like you just bought a brand new tank! Also, 2 weeks isn’t actually that bad for a coil when you factor in the cost.

      The reason for leaking will likely be due to the coil being a touch past it’s best, it won’t be soaking up that juice properly.

      Before changing the coil book that tank in for a spa day, it deserves it. Give it a good clean in hot water, dry fully then pop a new coil in.

      Let the e-liquid sit for 10 minutes in the tank before vaping to allow the juice to soak into the cotton.

      Also, not sure if you like the mod or just want a change but replacing the battery should also freshen things up increasing your battery life.

      If you fancy trying the Crown 4, you can check out our review here. Very good tank. The

      The Vaporesso Lux Nano is also a very nice mod, be careful dropping that one though πŸ™‚ Full review and opinion can be found here. If you have any questions on either product specifically please ask on those posts and one of the reviewers will be happy to answer.

      Let us know how you get on!

  6. I’ve bought a nvee pro sub ohm kit but I’m finding the tank which is only a 2ml size can I put a 5ml tank on the battery or is there a reason why I can’t I’m new to this so I’m not sure???

    • Hi Thomas,

      While you can of course use a 5ml tank on this battery, 2ml is the maximum legal capacity allowed in the UK/EU due to TPD laws.

      Not familiar with that particular device but just had a quick search and you can use different tanks on this mod.

      You just need to be sure the tank you buy doesn’t need more than 50W of power to perform.

  7. Hey,
    I’ve brought a 0.4 ohm coil for my Smok prince stick. Will this be ok? I was told I should only use 0.17 ohm/ Also will 50/50 VG/PG be ok?

  8. Hi, I have just got the Vapouriz Sub-OHM 40W starter kit, and I appear to be burning through coils every day. Any tips to stop them burning so quick? Or am I doing a rookie mistake… πŸ˜‰

  9. Just bought the Smok Mag with the v12 Prince tank and mistakenly have put an 18mg juice into it & using it at 42W. The taste is ok so is it ok to carry on until it’s empty or will it ruin the coil in some way?

  10. Hi. I have a question about my SMOK AL85. I just changed the coil last week, but it’s not doing anything typical of when the coil needs to be changed, oh the tank is from a SMOK QBOX, I’ve been using this set up (on recommendation from a local vape shop who sold me the AL85 and put my tank on and said “wala you’re set to go”) so all of a sudden last night it just barely does anything when I push the fire button, no umph, essentially.

    Now with the last time I took it in, it was giving me the umph but very quickly loosing all umph (sorry, not meaning any technical term with “umph”, but like the gusto with which it normally has, like in regards to it force (?) Or energy which it would produce, strength of hit maybe, idk what the correct term is) but i have been using this with the wattage down around 26.0, and only recently have been talked to about needing to keep the wattage over 30.0 something, but haven’t had any problems to date, so unsure if that has to do with this issue, but I have a dislike for it being even that high due to the heat I feel and prefer it lower, well right now even, at 38.0 watts its not making a difference in the umph.

    So, above the W for watts there is a box with a “H”, volts says 2.539, OHMS 0.164, AMPS 15.48 MODE WATTS, PCB 46Β°C, and last puff count..

    Did I somehow mess up a setting that is causing this lack of, or is this indicative of needing a new battery perhaps? I have no real idea of what this is due to, and thought to try google and see if I could find an easy answer and now more confused. It’s a 45 minute drive to the nearest shop and as dumb as I probably sound thought I’d give this try. Thanks, Sarah

    • Hi Sarah,

      Looks like you are using a low resistance SMOK coil (0.15 Ohm)? These generally require higher wattages to reach desired performance.

      It may be worth trying a few things.

      SMOK Coils can vary in quality, if you have been using for a week a change of coil should be looked at to ensure there isn’t a coil issue. Not unheard of for SMOK coils to last less than a week.

      If you prefer vaping at lower wattages, try out one of the higher resistance coils. I’m presuming you have the Baby Beast tank that came with the Q Box, so double check that is the case. The following coils may suit your vaping style more as they should perform better at lower wattages (30W range):
      – V8- Baby Q2 – 0.6Ohm coil.
      – V8 Baby M2 – 0.3Ohm coil

      You can see the list of coils and the recommended wattage use on SMOK’s website here –

      Do you have issues with umph from a fully charged battery? It may be worth buying a spare battery to ensure there are no issues. Always good to have a back up too. Samsung 25R are always a good option and widely available.

      The setting ‘H’ you have selected is Hard mode. FYI, you can change this to soft and normal mode. This is basically a setting that gives you extra umph/quicker ramp up time. As you have it set on Hard though and still aren’t getting the desired hit this is not likely to make a positive change in the vape. You can see how to change that in the video below for future reference :

      Sorry there isn’t a definitive answer. Vaping sometimes requires a trying a few different things to rectifying problems!

      Let us know if you have any other questions and of course keep us updated on how you get on.


  11. Hey, I have an Athos tank on a speeder mod and am currently using the A3 (0.03ohm) coil on 75 watts. I am finding it is drinking my juice. i know it will run out faster than my old Aspire pockex as it is a smaller ohm but after about 5/6 tokes i have to refill.

    Is it because these coil run on such high watts? Could i get a bit more juice time out of something like the Clieto which run at 40 -60W for an 0.4 ohm coil or is it just an annoyance of sub ohming?

    • Hey Adam,

      Some sub ohm tanks are a touch thirstier than others but when sub ohm vaping in general you will find juice does disappear a lot quicker than using a mouth to lung vape tank. So, yup in your words a definite annoyance of sub ohm vaping!

      The triple A3 coil at 75W will also fire through the juice!

      Not used the Athos tank personally but have used SMOK TFV coils that are similar and they are one of the thirstiest coils out there.

      I use the Cleito every day. I run the 0.4Ohm coil at about 30-32W and go through 2 to 3 tank fills a day with moderate vaping. This is with the old 5ml tank though.

      I would say 100% I get more than 15 tokes (based on your Athos being 2ml) though from the 5ml Cleito so in theory you should get a lot more than 5/6 from the 2ml Cleito. Of course, this can vary depending on your wattage πŸ™‚

      Let us know if you go for it and how you get on.



  12. I have just bought Smok alien kit vape with sub o tank I have 6mg am vaping at 23 watts but still feel like I need something stronger but have been told I shouldn’t be vaping 12mg as it’s too strong ?

    • Hi Jenna.. Not sure what tank/resistance coil you are using but vapers normally recommend 6mg with say a sub ohm tank as it can, for some, be quite harsh and deliver the nicotine a little too well! But… That doesn’t necessarily mean you will, we are all different when it comes to what we need from vaping.

      I’d say it’s definitely worth trying a step up in nicotine if you don’t find 6mg satisfying enough, using a 70 or 80VG e-liquid should soften the throat hit a touch as well so it’s not too harsh. Let us know how you go on Jenna!



  13. I read somewhere that sub-ohm vaping isn’t good for beginners so when I was buying my first vaporizer I didn’t want to buy one with just sub ohm atomizer. So I searched for something that could be switched after some time. After some time I found Vapour 2 and decided to buy it. I don’t regret my decision the Trinity vaporizer came with both “normal” atomizer and sub-ohm atomizer in basic pack so now I can use the sub-ohm one but started with the 1,2 one.

  14. Hi I’m after a bit of advice, I’ve tried so many different vape kits that I’ve lost count, even the apollo and v2 which I hated. I eventually settled with the innokin T18 using v2 platinum congress liquid which I love but my problem is the batteries barely last a few hours, that’s with new ones too. I’ve been trying to cut down the nicotine levels but now I’m down to 1.2 I think I’m using the vape more. Not sure. I’ve read so many conflicting reviews about what the best one for me would be. I don’t want a mod as I doubt I’d be experienced enough to use it but I need a vape easy to use like innokin t 18 but with a longer battery life. I’m also finding the v2 eliquids expensive and lately I’m going through them really quickly so if anyone could recommend an alternative to try I’d appreciate it.

    • Hi Karen, Thanks for getting in touch.

      The battery life is always going to be a bit of a problem with the smaller devices (and vape pen style devices) especially if you vape a lot.

      One option, especially if you are happy with the T18, is to have a second device or spare T18 battery so you can rotate, although not sure if the batteries are sold seperately.

      Other options are the Endura T22 – Uses same tank as the T18 but has double the battery capacity while still keeping a small form factor. It works the same way the T18 does, just press the button and vape.

      I know you said you aren’t sure on a box mod… But.. they are very easy to use. Simply set your wattage. Once you have done this you don’t need to do anything but press the button and vape.

      Good options for these that have improved battery while keeping a smaller form factor (of course bigger capacity mods are available):
      Apsire Zelos
      Wismec RX Mini

      As for better value e-liquids, there are a few options but as always taste is subjective and they will likely not be like Congress, what you are used to.
      Halo Vapour
      Jacvapour PicNic range – These allow for 50ml of e-liquid for around Β£13.99 but a little extra work is involved as you can see from the review. Again easy to do though.

      Hope that helps a little. Any other questions please ask.

      Thanks Jonny

  15. This site had been an real help cause you can never learn enough.

    I’m pre retirement cause of psychiatric disorders can go 6 days work without sleep then sleep for one day and have it so for a couple of months. Have gone thru the whole medical bunch Sweden can give or even eat 2 medications that doesn’t exist officially and only a couple of people in Sweden eats it maybe 2-300 persons it’s Dane medecine add the old dexedrine but with an new name i eat around 14 pills of those every day when i need to socialize.

    And have swedens worst diabetes over 15 years with so high bloodsuger so the meters at the hospitals or my own couldn’t show more than HI so i had an sugar addiction worst the doctors seen. As complications from having so high blood sugar from 13y old and im soon 33y or 34 in November “my memory literary fried from electrics shots from medical coma 10 years ago and took ect 7 days a week for 2 months and they did do anafranil drip at the same time as they pumped me with medicine that i found out 4 years ago that all that mixture was a no no but i was so depressed heard from Swedens leading professor om UmeΓ₯ university hospital top 1 hospital in Sweden for many years now, but she said dissent we fix so you got atleast β…“ of the levels you got now you will get blind and need to amputate toes foot maybe under leg/s and i had to go ambulance sometimes 2 times a week and my own big city hospital said they couldn’t threat me.

    And after that everytime o had to go ambulance for the stong ph in the body vomited nearly acid or read the same every time the chief doctor where i was laid in to the doctors always did you know this is serious you may not fix one month more.

    Really bad sight and i need to rest the strongest poison killers they have here every morning when i need a bathroom break but need to wait half hour just to stand on my legs. But anyways sugar addiction yeah sorry have very much adhd dyslexia and why i write so messy is cause i got writing curse thru my Autism spectrum syndrome or takes mostly my writing and talking cause i stuttre and ect treatment may have given me pre time dementia is very rare but they call it for now debris alike symptoms according memory that get worse.

    But easy 140 pills a week and they don’t want me to over eat. Cause i have been an advanced mix drug addict needles and it all, and if i didnt find one particular woman that said i do anything to help you she did throw away a good school in England for i have been forced jail or rehab 4 months before i had green skin that i didnt care for and see her eyes when i had one of my epeleptic seizures i felt something.

    I’ve had had an rough life duct up family my friends was the one helped me to grown up to handle things my self. had loaded pistol against my head by an crazy person that had taken to much speed and was really i don’t know… Been stabbed too. 2 heart stops stopped breathing a couple of times and i thought i was invincible cause i got the name Nikki Sixx of”then my city’s name” but i didnt take drugs cause of fun it was to cope work all i jag ro live sΓΆk all doctors said i would be dead at 30y old.

    I have had lymfoma cancer so treatment for that for one year was rough but i found out Dane day my then living with gf days she is leaving me and go to work as an hair cutter in some ski place in Hemavan and before that i found out after 5 years of working doing computer work and database making one of my departments paperless and made so right scale printings could be paid thru internet. But they said we must leave the 2 newest Co workers cause can only keep one and your main project is working flawless.

    then i got an mail that was for my boss from the economy chick that was sent earlier that day and if they had kept me 1 day now and no notice that i had to be fired i had been LAS that in Sweden meant that they had to keep me.

    And i jag bor much of a family as i said before but now back to vaping.

    I couldn’t get my sugar levels go down other goes to the hospital when they have an level over 17mmo/L i read often over 28-35+(40-55) when i got down to 20 my body reacted like I’m going in to an insulin coma got an pulse around 160bpm and my body just needed to rest candy sugar food I’m under weight but i ate 3 lunches 4 dinners and ate SONETHING all the time.

    But when i started vaping 2015 it someway fooled my bloodsuger when i was vaping sweet ejuices and it filled my body and my mind cause before getting most bloodsuger was harder than what I’m now am for 8 years I’ve been drugfree or 7.5 we Jag to move to the other side of the country so old friends didnt toss pills at me or leave them out in my mail box so i sold my apartment cheap gave away my car and 6 days after I’ve moved to the first place i could find that had an University cause then my wife was studying to be an attorney but she changed and is getting the highest level of psycosis nurse much about drug patients she wants to work with.

    But what i want to say i love your site in trying to figure out the perfect mod for my wife she loves small but on my dna200 she loved subohm ss316l dual fused clapton wires on an Griffin 25.

    I’ve been thru 12 mods with her and maybe the same amount of own atomizers i bought to her. And i got so lite income this site is really helping me find what i want to save maybe an half year of our should be an small dna 60/75 mod or something else she is soft vaping on an new bo vaping those pods work awesome but i want her to have an really great variable mod with easy if it’s an dna i could just set in the right profiles for her but i don’t know how good the other chipsets are and in Sweden everything is so costly.

    My latest but the minkin 2 is really nice but could be to hard for her and it’s too heavy and costly. But i will follow your site every day now she is going on 75 percent tobacco cigarettes and 25 percent vaping she is mixing between my cheap bought smok quantum for 18 dollars pink and the Mello 3 mini she got when i bought her an Pico 75w pink.

    I really want small good temp control with ss316l that i love my self i can put in the settings on ramp up time and curves and such just if the mod saves. But now I’ve written to much but if i save money for an half year to an year i couldn’t pay my bills and loans any money with so low income and 2 months ago the state takes 60 percent of my pension income i have.

    if i don’t but Netflix or ejuice stuff diy that’s costs 8 tines more here and they don’t have much and can’t find who delivers like cap or FA cause nicotine is cheap. So it certainly will comes to saving anyhow.

    Cause she saved my life if i didn’t get my self to rehab my liver 1 month later would had gave up. they didnt know if my liver would survive but i got lucky i don’t drink i don’t do drugs just money go to cheap lousy essences from molin berry wish i could use wizzy and get my favourite ejuices to buy from someone or the ingridiens to make like fun fetti and sweet stuff cause essences don’t go on the tax and i would pay the person for sound ingridiens or ESSENCE without nicotine just to add nicotine vg or pg my self.

    But i almost know no body. Vaping is my hobby. But i want to save my wife from cancer or the thing Smokey’s gets called kol in Sweden that’s when they are doing just get harder to breath cause of cigarettes. Sorry for so hard work but just want people to know i didn’t just quit SNUS and cigarettes the first day i vaped i got my DIABETES back to ok values for first time in my life.

    Just wanna say thanks for an awesome web site will check every day i don’t have to much stuff pain. AND I UNDERSTAND IF IT’S WRITTEN SO HARD SO NO ONE UNDERSTAND SORRY MY WIFE IT’S AT A FRIEND SHE OFTEN WIRES MY BLOG AND ALL SOCIALIZE CONTACT. BUT BEEN MOVE TO LIGHTEN UP from my chest a litle. Keep up what you all doing. You have my dream job. If you need any reviewers or just member reviews my wife is from England and is a grade a student and would love to cut my text and write it perfect for dslr camera and can record 4k πŸ˜‡πŸ˜‡ have a great week folks

  16. been on an eleaf 20w mod with an aspire nautilus tank vaping 12mg nicotine for 3 weeks. great little thing, lovely vape and never craved a cigarette once… decided I wanted a bigger hit so done a lot of research on sub ohm vaping I didn’t want to go straight into the higher end devices so looked at mid range devices.

    Decided on the innokin cool fire 4 plus 70w then decided I wanted a spare tank and something I could use further down the line in case I got a bigger mod so after reading a lot of reviews decided on a aspire cleito exo tank with the 0.4 coils these coils was perfect for me rather than the 0.16 coils as the recommended wattage use 40-60 so would be ideal for my mod.. as for juice I took some advice from my local vape shop and bought some asap grape nasty juice 3mg nicotine put it all together set the watts smack in the middle of the recommended wattage and wow what a hit!

    flavour and vapour is amazing and mod is good quality build I can’t stop puffing on the dam thing!!!! if I still get a cigarette craving iv always got my eleaf to turn too but at the minute I can’t see me doing it but early days yet…

    • Good to hear you are keeping off the cigs! I tried the Nasty Juice range as well for the first time the other week, a couple of really good flavours there!

      Even though the 3mg is a lot lower, the increased heat you are vaping at on the Cool Fire/EXO helps deliver the nicotine as if it was a stronger nic strength.

      Keep us updated on how you get on.

  17. Hello..
    I’m new to sub-ohm vaping (vaping is new to me actually).. There are some concern.. I’m using serpent mini rta tanks with average 0.7ohms.. With ipvs4 mod..
    The prob i’m having is my cotton burned quite often and i got this burn sensation which i hate..
    I also have this popping and spitting prob.. Looking forward for some advice.. My setting most of the time for 0.7ohms is 19-21W.. 70vg/30pg juice..


    • Hey Khai,

      So you’ve jumped straight into rebuildables! While there is nothing wrong with that these type of devices are generally classed as more advanced.

      The thing with rebuilable devices such as these is that there are different ways of wicking to get the best results and to get the best from a device.

      For your device specifically I would recommend checking out some of the reviews on YouTube here to see how they set things up

      Burning cotton can be down to a number of things:

      Not letting the cotton soak up juice for long enough before vaping.
      Chain vaping – (Again, not giving the juice enough time to soak through the cotton between vapes)

      Once a cotton is burnt it can’t be saved. The burnt taste can also carry over to the juice you have left in the tank, so this may also need to be emptied and replaced.

      Check out this guide for some help on spitting/burning problems. It’s mainly for standard tanks but some may apply to RTA use.


  18. Hey there! I just got a Sigelei Swallowtail and am using 0.5 ohm coil. I’m having a hard time finding my “sweet spot,” I don’t know what all the settings do lol. I had a kangertech before, 0.5 ohm and normally on like 20 W. but when I do 20 W in this one it shows the ohm as over 0.5. Help! I don’t know where to even start lol. Thanks!

    • Hey Chelsea!

      haha… We’ve all been there!

      The Swallow Tail looks beautiful by the way! Good choice.

      The ohm readings from coils can have a little variance so unless they are well out then don’t worry about that too much.

      You don’t need to worry about all the different settings. The only one you need to use at the moment to get you up and running is the wattage functionality.

      The best thing to do to find your sweet spot is to simply work your way up the wattage on the mod, 0.5 or 1W at a time. I normally start low and work my way up a little at a time.

      It does happen where different mods may need a little more/less wattage so don’t worry if the wattage is higher than what you’re used to.

      It’s just about finding the right spot for you.

      Have a go Chelsea and let me know how you get on.



  19. Hi. I have king baby i put tfv12 x4 coil and attached the atomizer on therion 166 and cks icon 200 both gives me .32 ohms instead of .16 labeled on the coil. Is that OK. Help me to understand . thanks

    • Hi Ahmed,

      There can sometimes be a slight difference on the resistance reading and what it says ‘on the tin’ so to speak. The difference shouldn’t be anything to worry about with that particular coil.

      Resistances can also change somewhat when the coil is heated.

      Have you tried any other coils? Do they read closer to the rated ohms?

      Also, be worth cleaning the connections fully on the tank and mod.

  20. Hi Johnny,

    Newbie here. I’m planning to get a sigelei 213 plus and a uwell crown 3/ uwell rafale or kanger protank 4. Which tank do you suggest for better coil life and budget. I’m currently using a predator 228 with the elabo tank.


    • Hi Hunais,

      The Uwell Crown 3 is the latest of the tanks and while we have this in the queue for review it is looking as if it’s a very good tank. So, out of the three you have mentioned I would personally go for this.



  21. Hello Johnny i just bought a new eleaf pico mini with melo 3 this is my first box mod. There are 2 coils 0.3 and 0.5 i found in my box now im using 0.3coil watt mode 30w with sony 1-vtc5 battery because of coil labelled use between 30-80w for example can i use my mod 20w? Or can i go high +50w to find my sweetspot thanks

    • Hey Serdar,

      Yeah for sure you can go to any wattage you want.

      As always with any tank/coil/mod combo I recommend starting low (20W if you want) and work your way up until you find your sweet spot.

      This may change depending on the type of juice and flavour you are using so you may need to have a play with the wattage settings for each new flavour.

      Any other question you have on this or anything else please let me know!



  22. Hi Jonny, I would really be grateful for some advice please. I am very stuck and confused. I want to stop smoking and start vaping properly but I just don’t know what to buy. I have been using e-cigarette’s but there is not enough vapour or nicotine throat hit. I have bought a pen which I didn’t like and then x2 sub-ohm’s, which I have found too harsh on my throat and chest and if I turn them down I don’t get any vapour!! I would like vapour and nicotine. Please can you help me, I’ve done research and can’t find any more information to help and don’t want to keep spending money for nothing!! Thank you so much.

    • Hi Samantha,

      Thanks for getting in touch! I’ll try and help where I can, of course if you want any clarification on any of the below please ask.

      What e-liquid (nicotine strength and PG/VG ratio) are you using?

      Just a quick note, the reason your sub ohm vape will be too harsh will be due to one or both of the following:
      Nicotine % too high – Higher nicotine helps with a stronger throat hit, especially so with sub ohm coils. Sub ohm coils require a lower nicotine content than a standard vape pen style device as the coils are powered by more heat. You will still get a good nicotine hit though. Recommended nic level 3mg/6mg.
      PG % too high. PG can be a touch harsher on the throat as well, especially with sub ohm coils. Same reason above. It is recommended to use a higher VG% e liquid which provides a smoother vape. Say 60VG/40PG juice as an example.

      So, with the above in mind, you may not need to buy a new device. If I were you I would just try a lower nicotine strength or possibly a combination of lower nicotine and higher VG. Try the former first, could save you a lot of money.

      I know it sounds counter intuitive to recommend a lower nic strength but you will still get a good ‘hit’.

      It’s difficult recommending a specific product as your wants may be different and I don’t know what you have used previously.

      But I will recommend a couple of devices/kits that give you a similar smoking experience.

      Innokin Endura T18 or Endura T22
      Aspire K3 Kit

      The above kits are all ‘Plus-Ohm’ kits. So all coils above 1.2Ohm that are a closer match to the cigarette smoking sensation. It’s recommended to use a juice upto 50/50 VG/PG for these.

      There are recommended box mods here.

      Or if you can be more specific in terms of size, vaping style (clouds, more of a cigarette smoking experience) I will try and narrow down. Let me know the make and models of what you have used and are currently using.

      But..Not to sound like a broken record! Try a different juice or different nicotine strength first πŸ™‚

      Thanks and hope it helps a little.

      It can be a pain at first finding something that works for you. Once you have that device though you will be good to go. So be patient, it’s worth the wait! We will help you get sorted.



  23. Hi , i have just bought the coolfire plus TC100 but i`m not that pleased with the v tank that it came with , i also have a coolfire plus with the isub Apex 3ml tank on which seams to produce alot more flavour and vape than the v tank does . i have tried all the different settings i can on the TC100 , the best i`ve found is using it with the SS BVC 316L 0.5ohm coil set at 45watts and 430 F in the ramp up setting , but still not as good a flavour as tha Apex . Does anybody know if i can use the Apex tank with the TC100 if i buy one , or any other good compatible tanks to use with the Coolfire TC100 ????

  24. I’ve got an evod mega and have just bought a subtank nano , will I be able to use this with the 1.2ohm coil? Thanks in advance

  25. Hi there I have the kangertech evod mega and was wondering if it fires isub tanks or other sub ohms tanks add I world like to mix up lung to mouth and straight to lung inhaling the evod mega battery is 1900mah..

    • Hey Ade,

      Thanks for dropping by.

      The Kanger Evod Mega won’t work with sub ohm tanks. These tanks have coils that are below 1.0Ohm resistance that the Evod isn’t compatible with unfortunately.

      There are some great sub ohm vape pens that have just hit the market that are friendly on the pocket if you are open to a separate device.

      Check out the SMOK Vape Pen 22, provides great flavour and performance. Think it’s only around Β£22 delivered.

      If you go sub ohm it’s a good idea (depending on the nicotine strength e liquid you use) to drop the strength t0 3mg or 6mg.

      Any other questions on the above please ask.



  26. hello, I just purchased a smok osub 40w kit and was wondering if I can put my kangertech subvod tank on to my smok mod without it blowing up or damaging it?

  27. Sub ohm vaping is definitely where it’s at! The flavor of the eliquid pops, it’s just perfect! When I started sub ohm vaping I thought to myself where has this been my whole life and why didn’t I know about this sooner!

  28. Hi

    I’m new to this Vaping and just got myself a Smok OSUB 40W kit.

    I’ve been told that you have to use a Certain Mix/Strength of juice depending on the Coil being used.

    The Coils I have with the kit are a 0.4 Fused Clapton Dual Core and a .1 Single Clapton Core.

    Can someone advise what strength juice would be suitable.


    • Hey Anthony,
      When sub ohm vaping (coils below 1.0 Ohm) then it is recommended to drop your nicotine level. As you haven’t vaped before then I can see why this must be difficult πŸ™‚
      Is the single Clapton 0.1 or 1.0 Ohm? I think it’s the latter, I was just using the SMOK Osub kit last week.
      I personally vape 3mg nic strength at 0.4/0.5. And I used 3mg/6mg with the 1.0 Ohm coil. And I use a mix of e-liquid with a 60VG / 40PG mix. You will be OK with 50/50 – 70VG/30PG though.
      As you are new to vaping then it will be a case of experimenting with 2 or 3 nicotine strengths.
      With 3mg, you will be able to use this with both of your coil options no problem.
      With 6mg, you will likely be able to use this with both coils, although it *could* be on the strong side with the 0.4 coil.
      With the 1.0Ohm coil you may well need 12mg nicotine strength to be satisfied.
      Again, Anthony, it’s a personal preference and the only way you will really know it to try a few juices out. Don’t mean to sound too vague but it all comes down to personal preference. What is good for one may not be for another.
      If you start on the 3mg and 6mg though you can always work it from there.
      Anything else let me know. Be interesting to hear how you get on as well!

  29. Can I use a 1.0 ohm coil with an Isub tank and a cool fire iv I want to go out and buy a pack or a couple 1.0 coils
    thanks Josh

  30. Sub-ohm builds often let users to enjoy much more flavor than customary clearomizers. As the vapor is exceptionally thick, it is possible to taste more of your premium e-liquid with each hit. And, in combination with organic cotton wicking material, sub-ohm coils can provide a vape with a very intense and clear taste.
