The name’s 12 – TFV12 and I’m here to drink ya juice and create a storm cloud – and I’m all out of juice – literally.

cloud beast king review

Yup say hello to the SMOK TFV12 Cloud Beast King and trust me guys n gals this is a cloud chucking behemoth. Just like it’s most recent brother, the SMOK TFV16.

It’s the obvious choice if you fancy yourself as a human volcano or have a yearning to become a new Marvel superhero – let’s call him Pea Souper Man.

This monster claims to be the King of the sub ohm tanks – or as I call it the sub Oh My God tank lol. Could it be one of the best sub ohm tanks available though?

Now as an aside you might be one of those vapers that think a coil capable of hitting 350 watts is ridiculous.

I hear you – I mean just how far does vaping need to go before someone says STOP!

But hey I think we’re missing the point here.

Vaping – apart from being the best way to quit smoking – is also fun!

And as a believer in freedom – and I mean real libertarian freedom – then I say whatever floats your boat.

I mean just because the SMOK TFV12 coils hit 350 watts don’t mean you have to hit those heights – or rush out and buy a vape mod that can handle it right?

But I’m digressing as usual – let’s see if we can fight our way through the fog and take a look at the ‘controversial’ Smok TFV12 Cloud Beast King.

In the Box

It’s your usual Smok packaging as in a colourful sleeve featuring a volcano spewing lava with a nice photo of the TFV12 front and center.

It’s a big bugger let’s put it that way.

Key Features of the Smok TFV12

OK apart from the 6ml bucket sized e-liquid capacity the key feature here has to be the coil that has split the vaping world.

The TVF12-T12 coil has the revolutionary duodenary head – duodenary btw is the word used to relate to the number 12 – so in this case the 12 refers to the amount of cylinders within the coil if that makes sense.

cloud beast king coil heads

Anyway it’s this monster coil that has caused some vapers to get their panties in a twist.

As I’ve already said if folks want to vape at 350 watts then so what?

If they can and it’s safe then more power to your clouds mate.

Personally it’s not something I can see myself doing – though [and this is the truth] for the purpose of this review I went out and bought a Wismec RX200S to see if the TFV12 Cloud Beast King vapes OK maxing out as I did at 250watts – more on that in a bit.

So apart from blowing enough clouds to blot out the sun on whatever continent you live what else has this beast to offer?

cloud beast king larger fill port

To be honest Smok has stayed true to the rest of the Cloud Beast family – it looks the same [apart from extra chunky knurling] – however the juice fill hole is considerably larger.

I know from experience it was a bit of a pain fitting larger glass drippers into that hole.

Otherwise it is what it is a bigger version of the TFV8 Cloud Beast – bigger in every sense given it’s as big if not bigger than my mini mods lol.

Design and Build Quality

It reminds me of a tractor or an off roader given its chunky knurling.

Now that’s not a bad thing – I like off roaders lol – but first looks makes you realize this is indeed a serious piece of kit.

Like pretty much all Smok products [I did say ‘pretty much’ lol] it’s wonderfully put together with nice machining.

Straight outa the box things are a little stiff but once juiced up the threads move nicely.

The absolutely ginormous airflow ring spins with just enough resistance to keep it in place – but it does keep on turning as there’s no catch to keep it in place. But like I said once you’ve set your preferred setting it pretty much stays in place.

cloud beast king airflow

As you might expect the coils themselves have huge juice fill ports of varying shapes and sizes with the V12-Q4 having funky looking lightning bolts instead of your run of the mill slits.

Not sure if that did anything to the cloud production or taste if I’m honest and personally I thought it looked a bit daft and the kind of logo Pea Souper Man might have on his costume 😉

Everything comes apart easily for cleaning and Smok includes a 510 drip tip adaptor should you wish to use your own.

How Does the SMOK TFV12 Perform?

Now anyone who says vaping doesn’t set off smoke alarms needs to go and talk to my 20 or so neighbours.

I live in a newly built set of flats [apartments if you’re posh] with state of the art fire alarms.

cloud beast king components

Now with both my large windows wide open I took a few pulls on the V12-T12 coil and within seconds my pretty large room was filled with vapour.

Unlike any other clouds I’ve created before this vapour just seemed to hang there!

I waved my arms around like a loon for a bit and if I’m honest it was like boxing candy floss!

Boy is the vapour dense!

Anyway – long story short – I spent the next half an hour tooting away on the three different coils and absolutely loving it – so much so I had a big stupid grin on my face the whole time – vaping on the TFV12 is fun!

Call the Fire Brigade!


I opened the door to visit the bathroom and within 3 seconds the fire alarm in the building was triggered and holy crap is it loud!

Cue disgruntled neighbours in their PJs with little wide eyed kids crying on the landings.


They knew it was me as the readout was flashing my flat number for all to see. I guess opening the door and seeing a huge grey sweet smelling cloud filling the hallways was a bit of a giveaway too lol.

Anyway if that doesn’t show you how the SMOK TFV12 performs then nothing will.

The vapour production is intense – it’s thick – dense and seems to have substance lol.

Flavour wise I’ve not been that impressed with the Baby Beast or the Big Baby Beast if I’m honest – but Smok seems to have cracked it with the coils I tried.

V12-T12 Coil


OK after letting this soak for a good twenty minutes I took it from 100watts to 250watts.

At 100watts it was a cold vape but with a decent flavour. The clouds were impressive to say the least and absolutely smashed the vapour production from the Big Baby Beast.

However once I’d gone through the gears so to speak I hit the 250watts and just Wow!

Never mind clouds for days or weeks we’re talking no sun for months lol.

And at 180 watts the flavour was absolutely stunning.



By far the most sensible [haha] of the coils you get with the kit coming in with a sweet spot of around 120watts.

Once again cloud production was phenomenal and the taste as good as I’ve tasted on a Smok stock coil – yeah even as good as the flavoursome low wattage SMOK Brit tank lol.

I did try to max this one at out 200watts and things got a little warm with the flavour dipping considerably giving me not quite a dry hit but the threat of one.



This is the coil with the lightning bolt cut-out juice flow holes so I was expecting fireworks from this one.

I took this beauty from 60watts to its max of 190watts in 20 watt increments.

At the lower end clouds were amazing whilst taste was weak.

I didn’t like the vape at 190watts as again it bordered on the threat of a dry hit – not that I got one but I wouldn’t chain vape at that wattage if you catch my drift.

However at 165watts the taste on this coils blew me away – it absolutely zinged off my tongue with clouds to die for!

As to the longevity of the coils I am currently reviewing Smok’s AL85 kit that comes with the Baby Beast tank.

It might be my bad luck but I am getting no flavour and tons [I mean tons] of dry hits after just one day with both the coils included in the kit – see my review soon.

I have used 70/30 and 80/20 VG and PG e-liquids on the SMOK TFV12 coils and a week later they are all performing and wicking well – and that’s using them every single night at high wattage.

What I Like

OK and no I’m not a cloud chasing wannabe lol – but I think this tank is fun with a capital F.

It might have pissed my neighbours off lol but it put a much needed smile on my face – it is brilliant.

king – big baby – baby

Sure it’s not the tank you take to the pub – unless you have a very understanding landlord lol because never in the history of the vaping phrase ‘this chucks’ has it been truer.

The TFV12 Cloud Beast King absolutely spews out clouds just like the volcano depicted on the box.

The cloud production doesn’t diminish the flavour either coming close to the Doge III dripper I’ve taken to using in the evenings – high praise indeed.

I love the design – the knurling makes this beast look as bad-ass as it is – yeah even the pretty rainbow colour I got haha.

smok al85 and cloud beast king

On a technical note the much larger fill port is a real improvement and as to the airflow well as you might guess it’s just mental – think a wind tunnel testing a sports car lol.

And despite all that airflow it’s reasonably quiet too.

I know it’s a big tank but given its design – slim around the bottom and broad at the top – it actually had no overhang as such on my Aspire Archon mod or believe it or not my Innokin Coolfire IV TC 100.

bigger than a pebble cloud beast king
bigger than the Innokin Pebble

Sure there’s the tiniest amount and sure it looks daft lol but actually if you wanted to you could fit it on a smaller mod.

Indeed it looked pretty funky on my Smok Stick V8 – but looks and overhang ain’t everything – this vape tank needs power an lots of it if you’re gonna get the best out of it.

What I Don’t Like

The juice consumption.

Look if you’re driving a high performance car you’d expect it to be gas guzzler – well it’s the same with the SMOK TFV12 Cloud Beast King.

As I said at the start this is as thirsty as a bloke coming out of a desert after a month – boy does it drink!

And given it’s a 6ml capacity AND given the coils are stuffed with cotton – your first few fills will see that increase as the cotton soaks it all up.

You might need to go down the DIY e-liquid route to keep this beast fed and watered.

If so, you can read our full DIY Vape Juice Guide here.

Like a dumbass I used a well-known expensive e-liquid and got through a 30ml bottle in less than 24 hours – now that hurt my wallet lol.

So apart from the fact you will change climates wherever you vape and you will need to walk around with a Jerry can filled with e-liquid and you will need a mod that will at least hit 100watts upwards – there’s not a lot to dislike 😉


  • 6ml capacity
  • Larger fill port
  • Variety of coils including 12 cylinder monster
  • Great flavour
  • Intense dense unbelievable clouds
  • Solid build


  • Thirsty and I mean THIRSTY
  • No RBA in the kit – that comes separately
  • Clouds are crazy so watch where you vape lol
  • Not TPD compliant

I have simpler vape tastes these days - I never leave home without a Caliburn G, a Vaporesso Luxe 40 or Innokin EQ FLTR and a CBD vape pen or bottle of CBD drops in my rucksack...or indeed an Aspire Nautilus Prime X in my pocket... At home I'll be using various mods topped with the GeekVape Zeus X RTA or the Signature Mods Mono SQ topped with the Augvape BTFC RDA... I'm a former journalist and now a writer and sometimes author... I'm ex Army - adore dogs and never happier than hiking over the hills or with a good book on a beach.

smok-tfv12-reviewYou will manipulate the weather with the SMOK TFV12 tank - it's absolutely mental and I love it ;)


  1. I adore the TFV8 coils to no end, however I stick my coils in the Rig Mod Tanker tank (for the compatibility and pure styling) and was wondering if the tfv12 coils fit the v8 could beast tanks too. If not I’ll be investing in one of these pretty soon!

  2. I have had this tank for about 3 months and honestly, it has never leaked at all. Maybe i was lucky but it has been very reliable. i have dropped it once or twice and nothing broke.. still have all my spares. thinking of getting the RBA soon…

  3. I am new to vaping and was hoping to use this product to help giving up smoking. So far it is very disappointing. It leaks like a shower so you can’t carry it with you. This was even after changing the coil as apparently the factory install has poor product control!! I did this following the feedback from others who also question this product. So ignoring the leaking and this meaning it can’t be carried on you, it simply doesn’t work. If I (or anyone else game enough) tries to use it they get 2 secs into drawing back and immediately cough up a lung. The supplier has said I got a vape liquid that was too high in nicotine (I followed their online guide??). So got the level they recommended and tired it this afternoon with the same result. I am happy you enjoy the product but offer this reply for balance as after a costly outlay I will likely have to toss it away as a crap product. It is a shame as I want and need to stop smoking and was hoping that vaping would help after years of trying.

    • The tank doesn’t leak if you buy the RBA and build your own coils and wick them properly. The RBA is only 10$
      You can also build higher resistance coils that require less power and don’t make as much vapor. More vapor means more juice. This tank can be used as a high capacity juice conserver with the right build, or you can go stupid and build coils that blow huge clouds which is pointless. Give the RBA a shot if you still have the tank.
