Build Quality & Design

For those familiar with the Cool Fire 4 Plus, then that is pretty much what you can expect from the TC100 as a mod. Innokin have used the same body and 3300 mAh battery albeit with some slightly different design accents.Innokin cool Fire IV Temp Control Mod review

The Cool Fire 4 and 4 Plus have been one of my favorite mod designs so it will come as no surprise that I’m a fan of this particular design.

For those that haven’t had their hands on the Cool Fire 4 Plus this is a solid box mod. It’s got a chunky build to it but also feels like it could take a bit of hard use. Not saying you should go out and throw this about but these box mods hold up well to being carried around in bags etc.

I haven’t got the biggest of hands but the curved back of the box mod makes for a comfortable fit in the palm of your hand.Innokin Cool Fire 4 TC100 Review

The oversized fire button is well positioned, the OLED screen is one of the better ones out there. Large enough and bright enough to be seen outdoors.

The two function buttons are featured below the OLED screen and the micro USB charging port on the side. This unit also allows you to vape while charging. Always a plus point for me.Innokin cool Fire IV Temp Control Mod

Innokin iSub V – Vortex Tank

Innokin have also released a new tank with the Cool Fire 4 TC100 kit. This time around we have the iSub V tank which is the latest from the iSub tank range.

Not all TC100 kits have this tank included so be sure to check. The Express kit comes with just the mod.

The iSub V – Vortex has the same easy coil swap system, so cross compatible with all iSub coils. The main difference is the top fill and chimney design.Innokin Cool Fire 4 TC100 box mod

When unscrewing the top cap off the tank the chimney and part of the internal base actual rises. There is a spring loaded chimney that seals off the tank when filling. When the top cap is screwed back on the chimney is pushed back down and the juice flow reopened.

Nice little feature and one I think is to reduce the possibility of leaking when refilling.Innokin isub V tank

It looks like your standard sub ohm vape tank but the size for me is great. Not a big ass chunky tank, just a well built, cleanly designed tank that looks good on most box mods.

How Does The Innokin Cool Fire 4 TC100 Perform?

The main, ‘shout it from the rooftop’, feature on the TC100 is the new Aethon chipset which promises ultra fast accurate performance with Ni200, Ti and Stainless steel in temp control mode.

The chip is accurate to 0.00000 ohms. My 0.5Ohm SS coil actually read 0.50805 or there about.Innokin cool Fire 4 TC 100 Mod

We will come back to the various coil performance, first lets look at the functions and how the TC100 mod works.

Functions

  • On/Off – 3 Clicks of the fire button
  • Place new tank/coil on the mod and it asks for coil type automatically. Use ‘+’ ‘-‘ function buttons to highlight and fire button to select.
  • Press fire button and ‘+’ function button to manually select Ti, Ni, SS, VW.
  • Press fire button and ‘-‘ to select ramp up wattage when in temp control. The lower the setting the longer the coil takes to reach it’s targeted temperature.
  • Press ‘+’ and ‘-‘ function buttons at the same time for 2 seconds to display puff counter, current coil resistance and current voltage.
  • Press ‘+’ and ‘-‘ (keep pressing) to flip screen. Change depending on left or right hand use.
  • Press ‘+’ or ‘-‘ to scroll through temp control or wattage settings.

All very simple to control and for the vapers among us who are familiar with Innokin mods then you will be familiar with the way it works.

The mod requires you to confirm your coil when removing and replacing your tank pretty much making this mod fool proof. It’s pretty hard to choose the wrong coil settings.

Apart from this and changing your wattage/temp you are good to vape when a tank is placed on top.

Ni200 / Titanium and SS Coil Performance In TC Mode

I tried out the whole range of coils, the great thing is I could easily swap the coils out without the need to empty any e juice. Simply unscrew the base of the iSub V, pull the coil out and replace.Innokin isub V Vortex vape tank

The mod will ask you if you have a new coil, select which one and away you go.

In temp control the nickel and Titanium worked well as would be expected.

The stainless steal coil I pushed to the edge and as in the other coil mediums the mod started to regulate the power as the cotton began to dry.

You could keep the fire button pressed for a lengthy time with a full tank of e juice and you would have a hard time burning your wick. Which is the whole point right!

I did find that when the cotton was pretty much dry that there was a slight tinge of a smoky cotton flavor coming through. But this isn’t a ‘real world’ scenario and normal people would have re-filled long before.

Having said that, filling the tank after this the flavor of the e juice was good, not tainted in any way.

I found the flavor of the Stainless Steel coils to be the best of the ones tested providing a very good flavor in both temp control and standard VW mode.

Battery life

The battery life for the range I was vaping in was good. The 3300 mAh integrated battery saw me through a day when vaping in TC mode at 400-480˚ƒ and 50W to just vaping at 30W in VW mode.

The mod is also supports 5V/2A fast charging with a compatible charger. Even with the supplied micro USB cable charging time was decent at around 3.5-4 hours.

What I Like

The temp control works a treat in all forms, including stainless steel. For vapers new to temperature control then this is as easy as it gets in terms of functions.

Build quality, as with most Innokin devices, is excellent. The added power upto 100W will fit in with even the most advanced vapers needs.

The iSub V tank is a great performer, the flavor, especially with the SS coils, is superb. Add to that the easy swap coil system and top fill it makes for one of the most convenient tanks around.

What I Don’t Like

It’s a tough one. There isn’t anything that is a negative. Maybe if you are vaping at the higher end of the 100W capacity the 3300 mAh battery may not last as you would like.

I don’t get up to these levels so the battery life was good for me.

Final Innokin Cool Fire 4 TC100 Review Verdict

The Cool Fire 4 TC100 pretty much has it all when it comes to performance across the coil mediums.

It’s a welcome sight to see stainless steel working a treat in temp control.

There is minimal difference in design and build quality to the Cool Fire 4 Plus so if you have that mod and are looking to step over to the world of temperature control then you know what you are getting.

I can’t help but be impressed with the devices Innokin release, from the Endura T18 / T22 aimed at new vapers to this, the Cool Fire 4 TC100, they seem to nail it every time.

Pros

  • Excellent Build Quality
  • Temp control works well with Ni, Ti and SS
  • Power up to 100W

Cons

  • Battery life may not be great for vapers constantly vaping at the top end of the power range.

I've been vaping since 2010 and been cigarette free ever since. Ecigclick was started to take a closer look at the mixed bag of e cigs that were available at the time. We have gone from a handful of reviews in 2010 to now covering a huge range of vaping gear with over 100 reviews and counting today with the help of the great review team we have here! I'm available on the blog most days, if you have any questions just use the contact tab and I'll get right back to you! Vape on...

  1. I just bought 1 of these.
    Some teething problems?
    1. the display does not alter, it remains on 20w, the -+ don’t function all it does is switch on and off.
    2. why do they offer so many options for the coils, it’s really confusing.

    • Hey Mike,

      When you pres the +/- buttons do yo get any kind of message on screen?

      The Cool Fires require the following to cycle through the wattage

      – Press ‘+’ or ‘-‘ button for about 1 – 2 seconds (until the wattage flashes on screen)
      – Remove finger
      – Then press + or – again and this will cycle through your wattage selection

      2. Variety is the spice of life so they say, some tanks offer more options than others. There are two main ways you can vape (with the TC100). In Wattage and Temp Control settings.

      If you are using the an iSub tank such as the iSub V then the following coils can be used in each setting.

      – Wattage mode coils – Kanthal / SS (Stainless Steel) / Clapton

      – Temp control mode coils – Ti (Titanium), Ni (Ni200), SS (Stainless Steel)

      It’s important you do not use Ti or Ni in wattage mode.

      The coil selection comes down to personal preference as all will offer a slightly different experience and may require slightly different wattage selection. I personally stick to wattage mode and don’t really bother with temp control at all.

  2. Hi, just got me a free tc100 upgrade since the cheap one I ordered still hadn’t arrived almost 3 weeks later. I use high vg 6mg and have the vaper set to 50w and leave the airflow open about 1 third, but, I don’t get any of this throat hit I hear u talking about. Your not supposed to to draw it in like a cigarette are you? You just suck like breathing in forcefully (not too much tho) and it’s also at least a 5 second burst. I would like to know ur thoughts on this please. Been vaping for just over 3 years now, so much better than cigarettes and don’t stink of smoke anymore!

    • Hey Daviebhoy,

      Good to hear you’ve been off the cigarettes

      With sub ohm tanks the draw is know as direct to lung. So instead of mouth to lung, like most would smoke a cigarette, you will want to draw straight to lung.

      The idea is to take a steady smooth draw.

      It sounds like the reason you are getting little or no throat hit may be down to the e liquid you are using. VG helps towards providing a smoother throat hit.

      Juices higher in PG will bring a touch more throat hit as does nicotine strength.

      Two things you may want to try.

      First, maybe try upping your nic strength to the next available. Although be warned, a higher nic strength than 6mg when sub ohm vaping can be pretty harsh depending on your juice.

      Secondly, it may be worth you trying a different juice with a higher PG ratio to see if that helps some. Although I wouldn’t go more than a 50% PG.

      Hope that helps a little. Any other questions please ask! And keep us updated with how you get on.

      Thanks

      Jonny

  3. Hey there I have a cool Fire iv tc 100 and just put a smok Minos tank on it with new coil to bed it in got watts on 25 n saying shorted how do I solve this problem?do I need to change the volts on it?please help cheers

    • Hi Steven,

      There are a few reasons it may be causing a short error.

      Usually down to the connection between the pin on the box mod and the tank.

      Few things to try:

      – First clean all connections (Mod and tank) thoroughly with cotton swab/tissue to make sure there are no loose metal shavings/gunk.
      – Don’t over-tighten the tank. Try unscrewing the tank ‘very slightly’ and firing to see if that works.
      – A coil change may be needed. Issue can sometimes be a dud coil.

      Have you got any other tanks other than the Minos? Do they work OK?

      It may also be worth getting in touch with Innokin support:
      https://www.reddit.com/r/Innokin/
      or – support@innokin.com

      Let me know how you get on.

      Cheers

  4. Hi, m having some problem with my tank and need help please.
    I recently replaced my coil and found out that these coils doesn’t fit perfectly in my tank leaving a tiiiiiiny gap. So, i think this is the reason why there is a wierd hissing sound when i vape with and it doesn’t produce much cloud even though am using 80vg ejuice as the draw fills kind of struggle. And its leaking aswell. These are isub SS coils i brought from amazon and none out of 5 coils fits perfectly like the ones did that came with the kit.
    Have you had or heard any similar problems? Please help. Thanks

    • Hi Ted,

      I can’t say I have ever experienced any isub coils not fitting properly. And I have used a lot of them including the SS.

      When you push the coil in just make sure that it sits flush in the slot. When you screw the base back on this should push up the coil slightly into place. The base should screw on easily.

      Have you tried any other coils purchased from elsewhere?

      There is a small possibility of a bad batch but I would thinks it’s unlikely. And it’s not something I have ever heard of or come across.

      If you are still having the issue it may be worth getting in touch with Innokin support to see what they suggest – support@innokin.com.

      Let me know how you get on!

    • Both very good mods. The Pegasus requires a separate (external) 18650 battery to operate wheras the TC100 has an integrated battery.

      So all depends on whether you are up to scratch on battery safety and happy to do further research into the best batteries for the mod.

      If you are comfortable with external batteries then it’s more down to personal preference. Looks, battery life, how much wattage you need etc.

      I personally use the Cool Fire 4 TC100 mod a lot and prefer this. That’s just my personal preference.

      • Cheers for the reply hopefully it will vape just fine with 80. Btw i find this tank a bit noisy, can you suggest me any tank that cost similar as isub v and goes well with coolfire tc, cheers

        • It’s a tough one with noise Bob. Most sub ohm tanks tens to have a bit of noise to them. I use the Aspire Cleito a lot and I don’t find it too bad but then I may just be used to it! It’s a great flavour tank though at a good price.

  5. Hi, i am very new to vaping and was wondering if somone could help me.

    I recently brought this new cool fire 4 temp control my first mod and was really excited but the experience hasn’t been soo good for me.

    The main problem i have is whenever i vape the vape that i inhale feels very hot and the driptip gets very hot if i fire it for even 3-4 sec. All i m able to do is fire it for 1-2 sec. N vapour isnt massive either. m i missing something?? Or doing something wrong please help.

    M using coolfire 100tc mod with 0.5 ohm kanthal coil (20-35w). E liquid i m using is 3mg nic 30-70 mix. I have had my mod for 3-4 days now and have tried to change voltage settings to see if it helps but if i increase my watt more than 20 the vape gets very hot and drip tip even hotter which has left my lips feeling burnt.

    Please help

    • Hi Jack,

      I have had tanks that get hot but not at 20W. Have you tried a new coil?

      Which coils did you get in your kit?

      Also, may be worth considering a different drip tip if that can handle heat.

      Let me know!

      • Thanx for the reply jonny..

        I had received SS n Kanthal coil with the kit but since m new to vaping i thought i would start with low wattage coil so bought the isub coil kanthal, 0.5omh 20-25w.

        The tank itself doesnt get hot but the vape i inhale feels very hot and drip tip gets hot n bas left me with a burning sensation on my lips. Now m afraid to use higher wattage coil..

        M using the same tip that came with the tank, so i dont understand why it gets hot..

        • Hi Tom,

          OK. Do you know what the resistance (Ohms) of the SS coil? The kit I received was 0.5 ohm SS coil.

          Try the SS coil, this can be used in both TC and wattage mode. Start off in wattage mode. Just work it as normal, start lower on the wattage and work your way up until you find a good point for you.

          It doesn’t matter what the recommend wattage is on the coil head itself. This is a guideline. It will simply come down to you’re personal preference whether that be 18W or 40W. Give it a try, there may be simply be an issue with the Kanthal coil you had with the kit.

          Also, have you tried with the airflow fully open. Tight airflow can result in a hotter vape.

          Not sure on your vaping style either but may be worth loosening your lips around the drip tip, allow a bit of air around there. It’s possible to actually vape with your lips barely touching the drip tip. Not that that’s the point here!

          Also, take slow draws, try not to pull too hard.

          Let me know how you get on with the SS coil.

  6. hi, can anyone tel me the best settings for the isub v i’ve been messing around with it for a few days and still cant seem to get it right so if anyone can let me know the best settings it would be a great help, thanks

    • Hi Ady,

      It’s really all down to playing and finding a setting that fits with you.

      For me, my preference is simply vaping in Wattage mode, between the 25-35W range, the specific wattage will depend on the flavour of juice I’m using at the time.

      If you are vaping in TC mode (only to be used with Stainless Steel, Ni200 or Ti coils, NOT Kanthal) then try setting your ramp up wattage towards the higher end, then work your way up the temperature settings until you find the setting you like the best. Again, you may want different temps or wattages for different e juice flavours.

  7. My got my tc100 2/3 weeks ago and been working great. But today it kept saying shorted got that sorted I think as can’t came back on but I have had to charge it 3 times today and as soon as I put it on charge it’s half Full already. Any1 know what the problem is? It’s only on 40w aswell.

  8. I recently upgraded to the TC100 after dropping my Cool Fire 4 plus off a high walk way in my block of flats! I have to say I’m very impressed with it and reading your review only confirmed my feeling on the product. I’m using NI200 in TC mode and find it a far smoother vaping experience over my Cool Fire 4 plus.

  9. I’m pretty new to vaping however have been a on and off smoker.. I thought I’d try vaping to curb my drunken urges to smoke .. I’ve bought this 100 tc model and my blasting a tank a day at 30 watts. @ 40 it hits my throat to much ..

    Heres my questions

    Would I vape less at a higher nic level say 6mg or would that really hit my throat ??

    Would I use less juice at lower wattage? ?

    I’m using premium juices at the moment 70/30 vg.

    Loving vaping and not stinking of tobacco..

    • Hi Stephen,
       
      Great to hear you have made the switch!
       
      What tank are you using and what is your coil resistance? ie: 0.2ohm/ 0.5Ohm? Also which juice are you using?
       
      In answer to your questions:
       
      Yes you could well vape less at a higher nicotine level but there are a few things to keep in mind when sub ohm vaping.
       
      6mg ‘may’ cause too much of a harsh throat hit, it really depends on the individual. I prefer 3mg but I am currently vaping a 60VG/40PG 6mg juice in my Cleito tank with a 0.2Ohm coil at 50W.
       
      The throat hit is fine for me but I definitely get more of a nicotine hit. I couldn’t vape this as much as I would a 3mg juice due to the increased nicotine hit.
       
      The results will differ from juice to juice though so this isn’t always an exact rule of thumb.
       
      With regards to the amount of juice you go through.
       
      Yes, the lower the wattage generally results in less eliquid used. There are tanks such as the Innokin iSub that have both sub ohm coils and 1.0Ohm/2.0Ohm coils. The latter 2 coils require less power so will result in the juice lasting that bit longer.
       
      For example, the 2.0Ohm coil has a recommended wattage range of 10-16W. Your juice will go a lot further, the flavor and vapour volume will still be good.
       
      Just think of it as the higher the wattage = more heat being driven to the coil. The higher the temperature a liquid is being heated, the quicker it will be vapourised.
       
      Hopefully that helps a little Stephen, as you will see, vaping is a bit of a journey into finding the right settings/flavours/solution to you. So a little experimentation is needed.
       
      Of course any more questions please ask.
       
      Cheers

  10. Cheers for the update Jonny, I have the Uwell ss coil installed I’m my crown tank, did they mention temps? I’m guessing similar to the innokin 190c-245c

    • They came back with the recommendation 300ºƒ-500ºƒ Rob! So pretty much 2/3rds of the TC100 settings! Can’t see there being much action at the lower end so as you will know, just work your way up until you hit your spot. Let me know how you get on!

    • This is the first TC mod I’ve owned and I’m really struggling to get any flavour out of it, I’m using the tank supplied along with innokin ss coil and a juice that I know has lots of flavour as ive used it in both a uwell crown and isub apex on my cool fire plus, I’ve got it set to the coils max temp of 245c but still struggle to get flavour, do you have any tips on where I could be going wrong?

      • Hey Rob,
         
        It’s hard to call but the below are common (and not so uncommon) occurrences:
         
        Have you tried the temp at a number of settings, up and down, even past the recommended max temp? Also have you tried adjusting the ramp up wattage?
         
        If you didn’t give the tank a thorough clean prior to using it may be worth doing so just in case there is any machine oil residue still present in the tank. Which can taint your e juice flavor.
         
        How does the SS coil perform in standard wattage mode?
         
        Also, it’s worth keeping in mind the Crown is renowned for it’s flavour. It is possible it just offers better flavor than the Vortex tank.
         
        Have you tried any of the SS coils from the Uwell with the TC Mod? Or tried the Innokin SS coil in the Apex to see if results are improved?
         
        Cheers

        • Thanks for the tips Jonny.

          Got home and have the Vortex tank a really good clean, put a new ss coil in and switched juices to the same that I have in my crown.

          Have to say it’s definitely performing better, not quite as good as the crown but alot better than it was, maybe it was just dirty or maybe I hammered the pre installed coil, I know I had it up to 315c before realising I shouldn’t be pushing it up above 245.

          What Temp can the Uwell ss coils be used at? Should I stick to a similar temp range 190c-245? Don’t think I would need it as still alot of flavour at 190c with a ramp up of 30w.

          Also tried the Apex tank with the juice I was using in the Vortex and still get a nice flavour at quite a cool temp which I prefer, maybe some juices prefer different tanks and coils.

          Thanks again

          Rob

          • Hey Rob,
             
            Good to hear things have improved a touch. You are right in that tanks and e juice can work better with some rather than others.
             
            I haven’t used the Stainless Steel Uwell coils for TC control and after reading a little it sounds like they may not be suitable for TC.
             
            Apparently they have nickel legs on the SS coils so don’t play well with temp control due to using two metals. I’m going to email Uwell for clarification on this though.
             
            https://www.reddit.com/r/electronic_cigarette/comments/3vtu6g/uwell_crown_ss_coil_clarification/
             
            Their coils are rated at the following, as you’ll notice, no mention of temp range for the SS coil
             
            Coil Specifications:
             
            0.15 ohm Dual Ni200 Nickel Uwell Crown Sub-Ohm Coil – 400 to 600 Degrees Fahrenheit
            0.25 ohm Dual Stainless Steel Uwell Crown Sub-Ohm Coil – 80 to 120W
            0.5 ohm Dual Stainless Steel Uwell Crown Sub-Ohm Coil – 30 to 80W
            1.2 ohm Single Stainless Steel Uwell Crown Sub-Ohm Coil – 10 to 30W
             
            I’ll let you know when they get back to me!

          • Update from Uwell.
             
            The the new Dual Coil SS 316 Coils are TC compatible. Of course with temp control mods that support stainless steel.
