The Smok TFV12 Prince is the latest in the TFV lineup of tanks. Possibly one of the most successful sub ohm tank ranges to hit the shelves.

There’s not a vaper alive who hasn’t heard of Smoktech, from the wild success of their Alien 220W mod to the extreme performance of the TFV12 tanks.

Smoktech refuses to go unnoticed and the tank I’ve been reviewing this week, the TFV 12 Prince…let’s just say it’ll probably get YOU noticed.

If you’re familiar with the Cloud Beast King from Smok or the Baby Beast, you’ll appreciate the fact that this one is effectively the heir to the King’s throne.

Since writing there is a new tank in the range. Check out our SMOK TFV16 review here.

What Can We Expect From The TFV12 Prince by SMOK?

Not only does the Prince measure in 1.5 mm shy of his father, the King’s diameter, the included coils are a touch less intense.

Instead of being recommended for vaping up to 350W like the King (whaaaat?), these included coils call it quits at 120W. The TFV12 Prince is, effectively, the King of the medium wattage vape.

It’s beastly, hard hitting and, with it’s bulb pyrex extension, features a killer 8ml juice capacity.

What sets it apart though, besides the crazy cobra drip tip design and royal aesthetic, is the range of cores included with this purchase…the Q4, X6 and T10 coil heads respectively. By now, we know to expect flavour and cloud to the max from our Smok coils.

I might as well tell you now, I wasn’t disappointed.

Build Quality & Design

On opening up the neat, black Smok box packaging, I’m met with this magnificent monster of a tank…I got the gold but there is a massive color range: rainbow, purple, blue, red, pink, green, navy, black, white, gunmetal, matte black.

smok tfv12 prince sub ohm tank

The first thing I notice on the TFV12 Prince is the awesome looking drip tip and the prominent crown style knurling around the lower top cap and the base. It’s very attractive and, combined with the bulb pyrex, giving this tank a massive 8ml capacity, this tank is a knockout.

The second big thing I notice is the little lock button on the top cap, finally a real lock for Smoks hinged top cap design that, hopefully, will allow vapers to keep that top cap in place at all times while vaping.

The adjustable bottom airflow is unapologetically massive. Two 15 x 2 mm slots glare at me from either side the base and a twist reveals tight but quality machining on this stainless steel creation.

The lock on the top cap, which you press and then swivel the cap away from, works brilliantly and the refill gasket reveals a nice accessible and big hole for your juice nozzle.

The Drip tip is easy to remove and, thats to beefy black o-rings which are visible through the glass, breakdown is as easy as can be.

Um…can I vape on this thing already?

How Does The SMOK TFV12 Prince Perform?

First up, I feel that, given the fact that the SMOK TFV12 Prince tank focuses on medium wattage action, a reduced airflow would have made sense…I doubt many vapers will really find this airflow does the job when open, it’s just too much for the wattage range of the included coils.

That said…once adjusted it’s better and I manage to get a restricted flow just how I like it.

There’s a tendency for leaking through the flow slots, there are always drips inside when I peer into these massive slots, even if the tank isn’t leaking outright. I’ve made a habit of keeping the slits shut at all times when not vaping.

Another issue I noticed is that the tank get’s really hot, even in this medium wattage range. Luckily the drip tip is huge and does it’s job of protecting your lips.

Beyond that, the massive bulb tank extension does the trick and for the first time in a while, I’m not having to fill and fill and fill.

I won’t harp on about the coils here because there’s a section for that, so read on.

How To Fill The SMOK TFV12 Prince Tank

  • Depress the top cap lock button
  • Swivel the cap to the right
  • Fill through the slot
  • Replace and click the top cap shut

Fill is easy, the lock effective and the juice port accessible and large.

How To Change the Coil

  • Unscrew the glass from the base
  • Unscrew the coiled from its seating
  • Replace
  • Wet the new coil head directly
  • Replace glass, being sure the coil screws into the upper shaft
  • Fill as normal

Stock Coil Performance

Okay, well for a change I started with the installed, higher resistance coil and…I was very impressed. This coil has brilliant flavour and vapour production, when the airflow was just open a smidgen, more than that and it’s too much for this coil. This coil, for me, operated best at 80W with a restricted flow. This coil’s rage is 40-100W.

The X6 has incredible flavour, a good deal better than the Q4. The same issues with the airflow, of course, but less pronounced here because of the higher range, 50 – 120 W on this coil. I got the most out of this coil at 90W.

This coil is the best performer, outstanding depth of flavour that can only be compared to an RDA or RTA and cloud through the roof, especially with airflow right down.
Range here is 60 – 120 W and I really like it around 100w.

What I Liked

I love the visual design and the cobra drip tip, I also enjoyed the pyrex bulb extension. I got an outstanding vape off all the included coils, with super flavour and cloud!

What I Dislike

I feel that the airflow slots could be a little smaller, maybe…hehe.

Final Review Verdict

With the SMOK TFV12 Prince tank, Smoktech have successfully met the needs of medium wattage vapers with excellent flavour, cloud, great juice capacity and good looks to top it off.

If you love insanely open airflow, then this tank will float your boat even more!

Personally, I love it and consider these Smok coils to be some of the best on the market, delivering flavour that can only be rivalled by an RDA or RDTA. Good job once again, Smok!

I would most certainly buy this again, in just about every available colour! Safe to say currently one of the best flavour and cloud sub ohm tanks I’ve used.


  • Supreme Airflow
  • Great juice capacity (Maybe not so for TPD effected countires)
  • Good Looks
  • Awesome drip tip
  • Easy dismantle
  • Childproof, swivel top cap makes filling easy


  • The airflow, for the most part, is a little excessive

Greetings Vapers! I’m a 34 year old writer, editor and massive vaping enthusiast (since 2015) based in the beautiful Helderberg region in South Africa. My passion for vaping has steadily grown since I started vaping in earnest (as has my scorn for smoking). See, I tried vaping years before that but returned to cancer sticks after a bad experience (PG sensitivity). When I finally got back on the vaping train I decided to make it my business to educate beginners and vapers in general, so that they don’t jump to the conclusions that I did. I visualise a world without cigarettes…not just for health reasons: I’m tired of picking thousands of cigarette butts up off my lawn every morning, tossed over the wall by passers by. I can’t believe I used to be one of those people!


  1. The tank i were looking for, must be the best tank for dual 18650 mods. Quality all around, looks awesome and t10 coil vape is perfect. Coil saturate very well thus making at last and perform really nice.

  2. The part:
    “The X6 has incredible flavour, a good deal better than the Q4. The same issues with the airflow, of course, but less pronounced here because of the higher range, 50 – 120 W on this coil. I got the most out of this coil at 900W.”

    I think you mean 90w.

    Great review tho!

    • Hi, Jay! Thank you for pointing that out, I went ahead and checked this, only to discover that you’re absolutely right! I had a stack of Prince TFV12 coils and thus, never actually got around to checking. My sincerest apologies for that bit of misinformation. I have updated the review accordingly. Keep well and keep vaping!!!!

  3. “Fill is easy, the lock effective and the juice port accessible and large”

    No.. No.. No.. Juice port isn’t large.. Large one is for kylin.. This is smaller than average.. Even Griffin has bigger juice port.
