SMOK TFV4 Coils – A Closer Look At 7 Coil options
I recently carried out a SMOK TF4 Sub Ohm tank review and thought it was one of the very best sub ohm tanks on the market, offering unrivaled cloud production and superb flavour to boot, with a large tank capacity, huge airflow options and a great top filling system.
It was a tank that was really suited for high power vaping with the tri and quad coil options included in the box- unfortunately though that did leave those that don’t vape at over 50w+ wanting as the included coils were designed to have a huge amount of power put through them.
Until now, those that don’t vape north of 50w were left with the single coil rebuildable coil head option, but things are about to change. SMOK have now catered to all sections of the market with the latest coils they have released for the TFV4 tank, from higher resistance coils, to temperature sensing coils and also a brand new dual coil re-buildable head.
There’s now a huge wealth of coils available for this beast of a tank, each offering something different, there’s so many I have had to write a separate review to cover them all! Let’s see what all of the different options have to offer us…
Let’s start off by looking at how the coil heads come packaged. Bar the rebuildable coil head, each individual coil version is housed in blister packaging within a black cardboard box, with the SMOK branding and information regarding the coil and which power range (and temperature if applicable) on the front.
The rebuildable coil option comes as a little ‘kit’, with two coils pre built inside, some wicking material, a screwdriver and spare screws, all housed within a plastic reusable container. The coil heads are a lot larger than other premade coils on the market, and that is because they are housing multiple coils inside! Seriously, these heads are huge…
TF N2 Standard Core – Dual Coil Nickel 0.12OHM, 420-600F
I started off by looking at the temperature control option with the TF N2 dual coil nickel head and the first thing that struck me was the stated recommended temperature limit range. Normally, I wouldn’t use an Ni200 coil at anything above 450F, as I find coil lifespan to degrade considerably at anything above that, however SMOK say these can be used efficiently up to 600F!
I started off by testing the coil at 420F and 30W, and I got a cool vape, nice flavour and some fairly good clouds, but it felt like there was a lot more to come. I raised the limit to my preferred range of 450F and 35W, the vape was still reasonably cool yet starting to get a little warmer, and the flavour was really starting to get going along with the clouds.
At 40w and 500F this seemed to be the perfect range for this coil, with a nice warm vape, outstanding flavour and some very good cloud production. With the temperature limit at 600F and varying the power from 45-60w I found the vape too warm for my liking and I seemed to lose a bit of flavour. Clouds were extremely impressive however!
TF N2 Air Core – Dual Coil Nickel, 2 Extra Air Holes, 0.12OHM, 420-600F
You may be thinking that the Air Core means an airier draw and bigger clouds. Not so- the Air Core coils are designed to cool the vape in temperature control by drawing in cooler air, this mixes with the warmer air to increase the flavour and this works incredibly well, I found myself much preferring the Air Core option to the Standard Core.
Other than that, the Air Core performs much in the same way as the Standard Core, however I found due to the extra airflow I could limit my temperature a little higher and push a bit more power through the coil!
Whereas with the Standard Core I found 40w and 500F to be my preferred range, with the Air Core I was vaping at 50w and 550F and the vape was truly outstanding.
TF Ti Titanium Coil – 450-600F
Continuing on with the Temperature Control theme the next coil I tried out was the TF Ti Titanium Coil. Now Titanium is growing in popularity amongst those that build there own Temperature Control builds, due to it being easier to build with and arguably offering slightly better flavour and an increased power and temperature limit to take advantage of.
With this in mind, I started off at 450F with the Titanium Coil and 35w. Now the vape was pretty disappointing here and I knew I had to ramp up the temperature limit and the power to get more out of this coil.
I jumped straight up to 550F and 50W and things really started to happen. Adjusting the power to 65w and leaving the temperature limit where it was was just outstanding- warm vapour, huge clouds and flavour on another level.
I was even able to limit the temperature to 600F and ramp up the power as high as 100W- some truly massive clouds were being blown then! If you are a cloud chaser and you are looking to give Temperature Control a go then the Titanium coils are definitely for you.
The Titanium coil was my preferred option over the Nickel coils, I’m taking nothing away from the great performance of the Nickel coils, but the vape from the Titanium coil was really something else. I found it to have better flavour, a warmer vape and much bigger clouds!
TF T2 Standard Core – Dual Coil 1.5OHM 20-45W
The TF T2 coil is the highest resistance coil that SMOK supply so far – and it’s definitely one for the flavour chasers. I found this coil to have absolutely excellent flavour, especially at the 37.5-40w range, I did find it needed about a tankful of juice to be vaped through it before the coil was truly broken in.
You also get some pretty decent cloud volume from this coil as well, but this one is really for the flavour chasers.
TF T2 Air Core – Dual Coil 1.5OHM 20-45W
With the TF T2 Air Core I found this to provide the best flavour out of all the other coil options, bar the TF Ti Titanium Coil.
The vape still stays warm north of 38w but the extra airflow makes things a little cooler and thus a little more flavourful too.
Clouds seem to be a touch denser than with the Standard Core option as well! Using this coil at the max of 45w was my preference, excellent flavour, very good clouds and due to the Air Core things never got too hot.
TF S6 Sextuple Coil Head, 0.4OHM, 30-100W
Definitely one for the cloud chasers. The TF S6 sports a hex coil configuration adding up to a monstrous 6 coils! Be warned, this coil drinks juice, even more so than the original TF Q4 quad coil, so be prepared to get through a lot of juice should you use the TF S6 coil.
The flavour is in my opinion even better than the TF T3 tri coil and TF Q4 quad coil and the vape gets warm as you approach 100w but it is strangely cooler than the TF T3 and TF Q4 coil options.
Some absolutely huge clouds were being produced by this coil north of 70w, and by huge I mean room filling! You do need to be vaping this coil north of 70w to get the most out of it, I found it to perform best in the 80-100w range.
If you prefer flavour and have this coil, then 80-90w is ideal for you, if you prefer flinging huge clouds than 90-100w will be your ideal range.
TF R2 0.25 Dual Coil RBA
The TF R2 Dual Coil RBA comes pre built with two dual kanthal coils that combine for a resistance of 0.25ohm, all you need to do (should you wish to use the included build) is simply wick them with the supplied muji cotton, prime them, and you are ready to go.
You also have two spares included in the kit which are ready to use so you can always just install these when the others give up the ghost. The pre installed coils work really well- I had been using mine at 75w which gave me outstanding performance.
It’s pretty similar to the single coil option I previously reviewed as part of the TFV4 review, you have a removable sleeve which gives you access to the build deck. There is a big airflow hole at either end of the deck, rather than one in the centre, with two posts at either side. You need to trap your coil legs under the post screws only this time around, and make sure your wick tails go slightly into the top of the juice channels.
It’s easy to build on and something even novices will get to grips with quite quickly. If installing your own build, the world is your oyster really!
I found that the dual coil RBA option handles high power far better than the single coil option, and much more build options are opened up to you to use.
Final SMOK TFV4 Coil Review Verdict
I’m really impressed with the wealth of different options available here, there is something to suit pretty much anyone’s vaping style (bar those that exclusively mouth to lung inhale), and each individual coil offers something totally different from the other. It’s a novel move by SMOK to offer this amount of different coil options, and one I would love to see other manufacturers also do the same.
A unique feature of these coils is that each individual coil is chambered separately, SMOK say to reduce ‘interference’ with other coils, I feel this does seem to improve performance with stronger flavour and denser cloud production. It may also improve the lifespan but I can’t be 100% sure on that as these coils are the only ones I have ever come across that have their own individual chamber.
I’m pleased to report that I am two weeks into using these coils in rotation, and not one of them is showing any sign of giving up the ghost yet, so the lifespan is fantastic. Pretty much all of the coils are vaping as good as they did on day one! They also don’t seem too gunked up either despite having a wide variety of juices put through them, from custard to desserts and high VG too.
Overall, these coils are a superb addition by SMOK. All options seem to suit the TFV4 fantastically well, giving you a huge wealth of different vaping options, and pretty much everyone is now catered for.
This makes the TFV4 tank a true all-rounder and it has now strengthened its position at the top of the sub ohm tank market!
