Separate Chamber Design

All TFV4 coil heads use the Separate Chamber Design, which can significantly improve the stability and reduce the interference with each other coil.

Vaping the SMOK TFV4 Triple Coil (40-130W)

We vaped the quad coil on the SMOK X Cube II and used our Max VG e-juice by Fa-Q.

50W – A few meagre whisps of vapor at 50W
70W – Some big clouds now, but not a lot on the flavor front yet
90W – Massive clouds as you would expect from a triple coil, but again not too much flavor coming through
100W – Huge huge clouds of warm vapor and the flavor is starting to come through now, but is by no means pronounced
110W – Getting warmer and better flavor
120W – Quite a hot vape now and I can’t inhale too long due to the heat and massive amounts of vapor!
130W – The flavor is reaching its peak now, but I can only do relatively short inhales due to the copious amounts of vapor!
140W – Still no burnt hits and the coil is wicking well. Massive vapor and the flavor seems to get better with the higher wattages

I won’t be vaping this any higher than 140W as I can’t inhale too long on the TFV4 without it getting too hot or there being too much vapor. The flavor on the quad coil is best at higher wattage and at the lower wattages not much flavor came through. You will need at least 120Ws of power to get the best flavor from this beast of a coil.

Vaping the SMOK TFV4 Quadruple Coil (40-140W)

Again we used the SMOK X Cube II and the same e-juice for this coil.

40W – nothing
60W – Nice vapor now at 60W and I can already taste some good flavor, much more so than on the triple coil at this wattage
80W – Amazing flavor now at 80W, much better than the triple coil. A nice luke warm vape with lovely billowing clouds of delicious vapor
90W – Still not too warm and even bigger clouds. The flavor is just amazing now!
100W – Getting hotter now, but again the flavor is just outstanding!
110W – Vapor getting a tad too hot for my liking now, so I can only take short inhales. Massive clouds and amazing flavor!
120W – Vapor is just too hot now, but there are no burnt hits as yet and the flavor is just like drinking the e-juice. I find the vape at this wattage unvapeable
140W – I can’t even hit this for a couple of seconds as it just scorches me straight away

I’d recommend vaping the TFV4 quad coil at 80-90W as anything above was too hot for my liking. The flavor on this coil was miles better than the triple coil and I wouldn’t recommend touching the triple and go straight for this one. It absolutely sucks up e-juice though, so do bear that in mind when vaping and don’t use an e-liquid that is too high in nicotine. Even a 3mg nicotine juice (our standard) was a bit too much for me due to the massive clouds and the amount of e-juice it went through.


Build Quality

The build quality on older SMOK sub ohm tanks was always slightly lacking (wobbly drip tips etc.). This tank has a very high quality feel to it and is extremely well made with some unique features. The coils themselves are also very well made and machined.

Amazing Coils and Many More Coming


First up I have to say that the triple coil was slightly disappointing in terms of flavor. It wasn’t disappointing when it came to clouds, but I would have liked some more flavor from it. The quadruple coil was a whole new story and the flavor was outstanding and on par with our favorite sub ohm tank to date, the Uwell Crown. It was almost like what I imagine drinking e-juice to taste like! The RBA section also worked very well and produced some gorgeous flavor.

SMOK have a huge range of new coils coming for the TFV4, which include Ni200 temp control coils and some coils designed for lower wattage vaping. It looks like they will cover all angles with this tank and it looks set to be a really interesting line up! I can’t wait to try the temp sensing coils and those lower wattage ones and will try and get my hands on them and update the article once I do!

Great RBA Section with Massive Juice Flow


The RBA is the best RBA section I have yet come across on any sub ohm tank, as it’s so big and wide, meaning you have plenty of space for different builds. The juice flow holes are massive and we didn’t have any issues with doing the wicking and getting burnt hits. We vaped the pre-installed RBA at around 30-40W and the coil was reading at 0.72 ohm. The flavor and vape was fantastic and up there with some of our favorite RTAs. The RBA section on this sub ohm tank is a great addition and I am glad they included it in the kit.

Unique Drip Tip with Cooling and Additional Air Flow

SMOK TFV-4 Drip Tip
SMOK TFV-4 Drip Tip

The drip tip is quite unique on the TFV4 and features additional air flow holes and a cooling system. The drip tip is made up of two sections, an inner tube and an outer one to help the inner one cool off. This means your lips only touch the outer tube and means it will stay super cool even when vaping at higher wattages. You can also use your own 510 drip tips with the TFV4 should you want too.

Unlike some of the older SMOK sub ohm tanks, the drip tip is extremely solid and doesn’t move and wobble at all!

Unique Top Filling

SMOK TFV-4 Top Fill
SMOK TFV-4 Top Fill

The top fill feature on the SMOK TFV4 is great and you just slide the lid across to open the top of the tank. The rubber o-rings at the top fit well and the tank does not leak at all, even when we layed it on its side we didn’t have any leakages. Despite this we have heard from others, that they are having leaking issues, so it seems to be a bit hit and miss.

Amazing Air Flow

The air flow on the SMOK TFV4 is great and features 4 different air flow slots as well as extra air flow in the drip tip should you want it. With the bottom air flow fully open the TFV4 provided a really nice draw and exactly how we like it.

5ml Juice Capacity

The juice capacity on the TFV4 is 5ml and this tank needs that as it gets through tonnes of e-juice. The top fill function makes it easy to refill, but it is useful to have the 5ml capacity.


There really wasn’t much we didn’t like about the SMOK TV4 and the below points are some quite picky negatives. It is all personal opinion, so make of the following points what you will as they might not be an issue for you!

Destroys E-Juice

This is a plus and a minus as the TFV4 produces massive clouds on its quad and triple coils, but in the process drains your e-juice! Be careful with the nicotine of your vape juice when using this tank as you will be getting through a tonne of e-juice very quickly.

Quite Wide (24.5mm)

The TFV4 is quite a bit wider than most some ohm tanks and is 24.5mm in width when most sub ohm tanks are around the 22mm mark. Having said that, the TFV4 fits perfectly on the X Cube II which is the device it is meant to be vaped with. We put the TFV4 on the Sigelei 150W and there was the tiniest overlap and you might have some overlapping on any thinner box mods.


The TFV4 isn’t a light sub ohm tank and weighs 92g. It isn’t a massive downside at all, but something to bear in mind when considering to purchase this sub ohm tank.


The TFV4 is an absolute beast and comes with two coils, an RBA section, as well as a spare pyrex glass, cotton and a screwdriver. However for $49.99 it isn’t cheap and the replacement coils will not be cheap either. Then again you do get a lot and this is a well-crafted and well machined sub ohm tank capable of chucking some big clouds and producing some great flavor. The RBA section is great and the tank works fantastically well using the RBA and its juice flow holes, so those who like making their own coils can benefit from this and save themselves some money. The TVF4 isn’t cheap, but it is in my opinion worth its price tag.


This isn’t something we experienced on the TFV4, but have been alerted to this by comments and messages on Facebook. It seems some people are having leaking issues on their TFV4s. It seems to be a bit hit and miss, so keep this in mind when making a purchase and note that this could be a big issue.


Wow this tank is ridiculous, in a very good way! The quad coil was astounding and so was the RBA section. The flavor from both particularly on the quadruple coil was outstanding and the best we have tried on any sub ohm tank (tied for first place with the Crown). If I imagined the flavor from drinking e-juice then the Quad coil is what I imagine it to taste like and that’s no exaggeration.

The TFV4 tank is well built, features top fill and has a really nice drip tip that stays super cool. There are also some great coils planned including temp control and coils for lower wattage vaping that look really interesting. The RBA section is also fantastic and the best I have come across on a sub ohm tank so far, making this tank a good alternative to an RTA.

The tank isn’t cheap and gets through shit tonnes of juice, but I don’t think people will care and I can see this being an extremely popular tank! Overall we were really impressed with this sub ohm tank and it is our favorite one we have tried since the Crown by Uwell.

My quad coil lasted a day and a half before it died Triple has more vapour Its a lovely looking tank but is shamed by my Vision MK tank when it comes to clouds But….the reason why its been binned is…. Did Smok think it would not leak with no seals, just bare glass next to bare metal I lost a third of a tank every fill up, it just goes under the glass bottom and straight up and out, all the way round the glass Even tightening tank so much that the first glass cracked wasn’t enough to stop… Read more »
