SMOK have been very active players in the sub ohm market recently, with their TFV4 tanks in particular offering almost unparalleled performance when it comes to high powered cloud chasing vape tanks.SMOK TF RTA Review

We are yet to see an RTA from them yet- until now that is, with the release of the SMOK TF-RTA which offers two options, the G2 sporting a two post Velocity styled deck, and the monstrous G4, which sports a deck for quad coil builds!

The SMOK TFV4 tanks have offered superior performance for cloud chasers, especially with the incredible amount of coils available for them.

So let’s have a look at whether SMOK can crack the RTA market with the SMOK TF-RTA G2 and G4.

Build Quality and Design

The SMOK TF-RTA is manufactured from Stainless Steel, with a Pyrex glass tank section, and it shares a lot of its looks with the original SMOK TFV4. SMOK TF RTA Tank review

You have a choice of two different color options at present, in black and stainless steel, and the width of the tank is 24.5mm meaning that it will overhang any 22mm width mod.

The drip tip features an insulated inner layer against heat, and it is 510 threaded so you can use your own drip tip should you wish to do so.

There is juice flow control included, so by twisting the tank you can open or close this off when filling, and the tank is top filled by opening the swivel top. SMOK TF-RTA G2 and G4 Review

All the threading is smooth and clean here, and when cleaning the SMOK TF-RTA you can disassemble it completely.

Building the SMOK TF-RTA G2 and G4


There are two different deck options with the SMOK TF-RTA, you have the G2 deck which has a two post design matching the velocity deck, and the G4 deck that has a post arrangement that is for quad coil builds.SMOK TF-RTA review

There’s a load of space to build here and both decks easily accept large diameter coils.

They both come with Clapton coil builds already in them, the G2 deck has a dual Clapton build that has a resistance of 0.45ohm. SMOK TF RTA G2 Tank

The G4 deck has a quad coil build with spaced Claptons for 0.14ohm.SMOK TF RTA G4 Quad Coil

You just need to insert your favored wicking material, I’ve found cutting the wick in line with the top of the juice channels works best, and you can vape away.

The G2 deck is very easy to build on, with the velocity posts making dual coil builds easy, the G4 is a little trickier to arrange quad coils on however!

How does the SMOK TF-RTA Perform?

For cloud chasing, there isn’t much out there that can match the SMOK TF-RTA with the G4 deck. This supports quad coil builds that can handle very low resistance and high power with a very warm to hot vape, making this a perfect choice for cloud chasing.

I found the G2 deck to be better for flavour, the lower power offering a bit of a cooler vape and much more flavour coming through from your e juice.SMOK TF RTA G2 Deck

Juice consumption is one thing to remark on here, both the G2 and G4 get through juice like it is going out of fashion!

Overall the SMOK TF-RTA definitely rates as one of the thirstiest tanks I’ve ever come across, however with the G4 deck it has to be the cloudiest RTA I’ve ever used!SMOK TF RTA G4 deck


The airflow matches the airflow control found on the SMOK TFV4, which means that you have four massive airflow slots around the base of the tank, and a very smooth airflow control ring.SMOK TF RTA Airflow

The airflow is easily adjustable, however this tank is definitely not one for those that mouth to lung hit, as even with the airflow closed right down this tank is still a lot airier than most other RTA’s out there!

When you have the airflow set to its widest setting, then you are well and truly in cloud chasing mode, and the vapor production is on a level that most other tanks cannot compete with!

This is one airy tank for the lung hitters, and it’s quite possibly the airiest RTA I have ever experienced.

What I Like

If you want high power and pure clouds, there isn’t very much out there that can compete with the SMOK TF-RTA and the G4 deck. This is capable of easily handling over 100w, and with the generous airflow, this blows clouds that are on a whole different level to anything else out there.

The G2 deck can blow some pretty decent clouds too, but if cloud chasing is your thing then you will want to go for the G4 option.

The G2 deck offers excellent flavour, the flavour here really is on par with a lot of some of the best flavour tanks I have tried. It’s a rich, warm and very tasty vape.

The build quality is excellent with this tank, it feels solid and everything is smooth. I didn’t find a trace of machine oil present, and I enjoyed the fact I could strip it down fully for cleaning.

The top fill system is the same as the one found on the TFV4, which is one of the best top filling systems around.

The price point of this tank really is superb when you consider the build quality and performance. It most certainly out performs a lot of the more ‘premium’ tanks on the market today.

What I Dislike

The heat generated by this tank is pretty insane at high watts, it does get very hot indeed after a few puffs, and this also affects the vape too.

If you don’t enjoy warm vapes, you may find yourself a little uncomfortable with the vape provided by the SMOK TF-RTA at high wattage, with the G4 deck in particular.

You may also find yourself needing to lower your nicotine as this tank hits very hard indeed!

The G2 deck offers great flavour, and has to be the choice for those that prefer flavour over clouds, but it’s still a very loose draw and doesn’t seem to fare very well on the flavour front when you use under 30w.

If you aren’t spot on with your wicking on both decks, you will suffer leaks or horrendous dry hits. Even the wick being slightly out of place with this tank can have a big detriment to performance, it’s not forgiving at all.

The G4 deck is also a fiddly build too, when it comes to rebuilding on this deck you will need a lot of patience.

This is a very, very thirsty tank. It burns through e juice in no time at all, as the wicking channels are large and it is designed to be used at high power too.

Final SMOK TF-RTA Review Verdict

If you want the best clouds available from a tank, then the SMOK TF-RTA G4 is the one for you.

If you want an RTA for outstanding flavour that is still cloudy, then the SMOK TF-RTA G2 is an excellent choice.

Both of these options are superb, and this marks a big entrance to the RTA arena from SMOK.

The price point is excellent as well. For the price being charged for both of these options, I don’t think there is much better out there at the moment.

Been vaping full time for three and a half years, started on cigalikes for a fair while then curiosity got the better of me and I moved onto an ego/ce5 set up after, a month or two later I was seeing people walking around with these interesting shiny tubes and I thought 'I gotta get one of those'. Before I knew it a trip down to my local B&M got me my first VW mod, an Innokin SVD, paired with an iClear 30, and I was hooked. Soon after that I was jumping to VW mods both box and tube shaped, before I then made the jump to rebuilding and thus sub ohming, with my first RDA and mech mod. These days I'm still preferring mechanical mods, but using VW mods with both RDA's and tanks alike whilst on the move, most importantly I am still loving vaping!
