Dubbed the Baby Beast Brother, the TV8 X-Baby is the latest Sub Ohm tank from SMOK. Unlike the previous models SMOK have opted to make the switch to a top airflow design. The tank has a 4ml capacity, fully adjustable and comes with two coils and a replacement glass tube.

We’ve already covered quite a few versions of the Baby Tank so let’s have a good look to see how this one compares!

SMOK TFV8 X-Baby styling and build quality

In my opinion this tank is very well put together and it feels nice and solid. The Stainless Steel construction is of a good standard and the anodized painted finish (we received the metallic red) looks seriously smart. The tank glass is reasonably thick and should an accident occur a replacement tube is included in the box. I felt the thick O-rings were well good and they hold the glass securely. This tank has a diameter of 24.5mm which is a bit of an oddity but I thought it looked great on my Therion 166 and there was no overhang at all.

What is interesting is that even though this tank has a capacity of 4ml the overall height of 39mm is relatively compact. Logos are kept to an absolute minimum with only the manufacturer name “SMOK” displayed in white lettering located on the airflow controller.

The drip tip is of the wide bore variety and made from Delrin. It is a good fit and feels comfortable on the lips when vaping. Keep in mind that you are pretty much stuck with it since it does not feature a standard 510 fitting. I did try my Half Moon Mod drip tips and while they do fit they are sadly far too loose to be used. Lastly the tank features a standard non-adjustable 510 pin.


Airflow is very full on with this particular tank so it is ideal for anyone who prefers a direct lung inhale style of vaping. Closing the airflow down results in a restrictive lung inhale. Although you can kind of get away with an extremely loose mouth to lung vape if you heavily close down the airflow it doesn’t really suit that style of vaping in my opinion. This is a cloud chucking tank for those folks who love lots of airflow!

The airflow controller works well, being simple to adjust and it nicely stays in position.

Ease of use

Swapping out the coil is very simple since you only need to unscrew the base. Filling is equally straightforward and uses the trademark SMOK hinged top swing lid system. The filling hole isn’t massive so might present an issue if you still have dropper bottles lying around but there is plenty of room for all new TPD compliant 10ml PET bottles.

How does it vape?

I did initially wonder if the switch to top airflow would lead to some compromise on flavour with this tank but I am happy to report that was not the case. The flavour was really good considering just how airy the draw is and I think most people who like this style of vaping will be very happy with it.

If you live with other people who don’t like a lot of vapour around them then you are probably best avoiding this tank because it will land you in hot water. The TFV8 X-Baby puts out some very thick vapour so things tend to get foggy fast and even closing down the airflow doesn’t make that an enormous difference. Of course if you love clouds then you will really have a lot of fun with this tank but keep in mind it isn’t as ridiculous in terms of sheer cloud potential as the old TFV-4.

Typically I am not normally a fan of extremely airy atomizers but I found if I set the airflow to half open the vape was very enjoyable and since I liked the flavour I was getting I ended up running a few tanks worth of juice through it. I think what I really liked about his product was the fact that it felt very convenient to use. Max VG juice did present a slight problem since the wicking slots in the coil aren’t massive so you can find the vape occasionally borders on a dry hit. Providing you are using 70VG-80VG juice you shouldn’t have any serious issues it just depends on whether you chain vape as much as me.

As you would expect given the airflow the juice does drain extremely quickly so if you’re on a budget be warned. Thankfully this tank is 4ml capacity which does offset the problem slightly and filling is quick and easy thanks to the trademark SMOK hinged top design.


This is a seriously nice tank from SMOK which offers great flavour, excellent airflow and outstanding vapour production. The switch to a top airflow design is a welcome one in my opinion and reduces any chance of leaking.

The only real downside to the TFV8 X-Baby is that it literally devours your juice but that’s the price you really expect to pay with a design like this. Do check this tank out if you like the sound of it!
