SMOK TCT Sub Ohm Tank Review



In this article we review the temperature control sub ohm tank, the SMOK TCT. The SMOK TCT is very similar to the SMOK VCT Pro, but instead features two 0.15ohm Ni200 coils for temperature control vaping. The SMOK TCT also has 0.5ml more e-juice capacity then the VCT Pro and also has a more secure drip tip (VCT Pro drip was slightly wobbly). Apart from that they are same tank and the coils can be interchanged meaning you can also use the Kanthal coils from VCT Pro in the TCT or vice versa with the Ni200 coils.

Notable Remarks

Vaping the 0.15ohm Ni200 Coil (400 to 600 degrees Fahrenheit)

SMOK TCT N2 Ni200 Coil
SMOK TCT N2 Ni200 Coil

We vaped the 0.15ohm Ni200 coil on the Cloupor GT temp control box mod. We used our Fa-Q Funky Monkey max VG e-juice.

180˚C – Not much vapor before this temp. A very cool vape right now.
200˚C – Still a cool vape, but flavor starting to come through now.
220˚C – Flavor isn’t quite there yet, but lots of vapor.
240˚C – Flavor just jumped out now and still a nice cool vape with good clouds.
260˚C – Lovely luke warm vape
280˚C – A warmer vape now, but more flavor coming through now.
300˚C – Drip tip and tank getting quite hot now, so I would stick to between 260-280 degrees.

We vaped the SMOK TCT with the air flow on the drip tip closed, as the air flow is really good on this tank. I find you lose some flavor when you open the drip tip air flow up. We would vape these Ni200 0.15ohm coils at around 260-280˚C.

Vaping the 0.6ohm Kanthal Coil 30-80W (from the SMOK VCT Pro)

We thought we would try and see how the Kanthal coils vape compared to the Ni200 ones.

30W – Not much vapor or flavor at all at this wattage.
40W – Ok vapor, but little flavor.
50W – Decent vapor, not much flavor yet.
60W – Flavor coming through now and a nice warm vape. The tank itself is getting noticeably hot now when vaping for consecutive hits.
70W – Lovely flavor and big clouds. If you don’t have the drip tip air flow open, the drip tip will get hot very quickly. This does in my opinion mean you lose some flavor when opening that air flow.
80W – For me the TCT is just getting too hot at this wattage and the vape isn’t really bareable for me on longer consecutive vapes.

I’d vape the SMOK TCT on the 0.6ohm Kanthal coil at around 60W, as above that, the TCT tank gets far too hot.


5.5ml Tank Capacity

I really like the 5.5ml e-juice capacity on the SMOK TCT. Sub ohm tanks get through a lot of e-juice, so the 5.5ml e-juice capacity is really handy. This makes the TCT one of the larger sub ohm tanks in terms of capacity and yet remains 22mm.

Good Airflow and Auxiliary Airflow in Drip Tip

The bottom air flow rings feature to large air flow slots which allow for plenty of air flow on their own. In case that isn’t enough the glass drip tip features a handy auxiliary air flow, which can be used to keep the drip tip cool at higher wattage vaping.

Good Ni200 Coils for Temp Control Vaping

In terms of temp control sub ohm coils, the TCT 0.15ohm ones were amongst my favorite that I have tried so far. The flavor from these coils was fantastic and we really enjoyed vaping them at around 260-280˚C (500-536 degrees Fahrenheit).

Good Flavor and Clouds

As I mentioned above, the 0.15ohm Ni200 coils produced some gorgeous flavor and chucked some nice clouds. In terms of pre-made Ni200 coils, these 0.15ohm ones are definitely amongst my favorites when it comes to flavor and a temp controlled vape. The Freemax Starre Pro is another good sub ohm tank when it comes to Ni200 coils, but for me the TCT coils tasted better!

Additional Red and Black O-Rings

I like the fact that SMOK included some different colored o-rings for the TCT. I really liked the black ones!


Re-Filling is Tricky and No Top Fill

​This was my biggest annoyance about the SMOK TCT. To re-fill the tank you have to unscrew the base. After having vaped the tank for a while the vacuum causes the o-rings to get stuck quite firmly into place. Trying to unscrew the base away from tank was very difficult. I can see many people breaking their first Pyrex glass taking it apart, as I have almost done a few times. Thankfully there is a spare with the TCT kit.

A top fill function would have been very welcome with the TCT tank and it means re-filling this tank is a real pain. I think the top filling function has become the norm for sub ohm tanks, so it is slightly disappointing that the TCT doesn’t have one. I guess that is why SMOK have now released the TFV4, their latest beats of a tank with top fill.

TCT gets very Hot Using Kanthal Coils

When using the 0.6ohm coil at anything above 50W for longer periods of time, the tank itself got incredibly hot. It got so hot I felt I couldn’t carry on vaping at the higher wattages, for fear of something going up in smoke! This isn’t the case with the TC Ni200 coils, as obviously then the temperature is controlled and kept at a constant heat.


I know SMOK have now released their new beast of a sub ohm tank called the TFV4, but I still think there is a place for the SMOK TCT. At $21 and around half the price of the TFV4 the TCT delivers a fantastic temperature controlled vape on its 0.15ohm Ni200 coils. Its coils won’t break your bank balance either, unlike the TFV4! The TCT also has a fantastic juice capacity at 5.5ml and they finally fixed the wobbly drip tip issue!

The only thing that really bothered me was the tricky re-filling and lack of top fill and now there is the TFV4, I am not sure SMOK will change this on the TCT. Despite this, it’s a very solid and perhaps the best tasting temp control sub ohm tank we have tried to date. Its Ni200 coils were delicious and vaped very well!
