The Smok Devilkin 225w vape kit comes topped with the TFV12 Prince sub ohm tank and is yet another release from the prolific vape company.


Sadly prolific hasn’t meant quality with some recent releases not very well received by reviewers and the wider vaping community.

It seems Smok has been going through a strange phase recently with lots of tacky and over designed all singing all dancing LED light up everywhere devices that not only look poor but perform poorly too.

Not really since the Alien mod [and that had issues] has the company received its early accolades and with recent releases such as the Mag Baby kit getting a mauling from Deano and the Resa Stick getting an equally bad review from yours truly – Smok really needs to get its act together.

So What Can We Expect From the Smok Devilkin Kit?

The Devilkin kit includes the excellent TFV12 Prince tank, arguably one of the best in the TFV range. The mod itself is powered by dual 18650 batteries and, should you need it, can fire upto 225W

So has the Devilkin pulled their reputation out of the hell fire?

Let’s take a closer look.

The Devilkin kit was sent to me free of charge for the purpose of this review and as always my thoughts and opinions are my own.

Incidentally I’m taking a close look at the mod and NOT the TFV12 Prince as Laura-ann has done an extremely detailed review already.

Key Features

This is a dual 18650 battery mod with a max of 225w and the first thing of note is the very nice and crystal clear TFT 1.3 inch HD colour screen.

The device is a comfortable curved ergonomic design with the much loved side fire bar.

The options are typical Smok with choice of ramp up – screen colours – full temp control suite – puff counter and memory settings.

Smok has included plenty of protections including overheating – short circuit and 10 second vape cut-off plus more.

There’s also what Smok is calling an ‘intelligent atomizer recognition’ which in effect prompts you if this is a new or old coil…

Design and Build Quality

The Devilkin looks like a cross between Smok ProColor and iconic Alien and is quite the looker.

And yeah I’m saying that even though I got the black and gold version – hey it’s something those atties with gold banding and golden decks will look matchy matchy with lol.

gold mod rta

It’s not a device I would look at twice when vape shopping on line if I’m honest but in the flesh it’s actually quite nice – though that cobra design on the back is a little loud for me.

smok devilkin design

The screen is an absolute joy – crystal clear and no issues reading it even in direct sunlight with the ability to change the colours a bonus.

It really is ergonomic too – if a touch heavy – the curve of the device sits nicely in the hand making the fire bar perfect for right or lefties – finger – thumb or grip firing.

smok devilkin battery compartment

Build wise I really can’t fault it with a solid battery door with the merest amount of rattle [I had to strain when shaking it lol].

The fire bar has a lovely clicky action as do the perfectly placed up and down buttons.

The paint/finish feels rock solid too Smok having been mauled over the shocking job done on the original Alien mods.

Despite its seemingly wide body it just about takes the included 28mm TFV12 Prince tank.

Speaking of the tank I won’t be reviewing that as I’ve already explained.

How Does the Smok Devilkin Mod Perform?

So will it hit 225w?

I doubt it – Smok has been proven [to be fair so have other companies] to be a little loose with their estimates lol.

That aside do you know what I’ve actually enjoyed using the Devilkin!

smok devilkin kit in hand

It is a little on the heavy side but fits nicely in the hand with pretty instantaneous fire time and has handled everything I’ve thrown at it.

The highest I’ve gone is 180w and trust me it felt as if it was making that no sweat.

My basic temp control test was shall we say a little worrying with a much darker banding than I’ve got off other devices but nothing to worry about because even after the third 5 second fire nothing caught alight.

The menu is a little clunky if that’s the right word and it will take a few goes to get things sorted but once you’re clear on what does what it’s all good.

Battery life is actually very good indeed with a couple of 3000mAH 18650 giving me a solid day and a half vape time – and that’s me using it as my go to mod.

Overall it’s actually a solidly built solidly performing mod.

The full and extremely detailed review of the TFV12 prince tank can be read HERE.


  • Ergonomic indeed!
  • Good build quality
  • Solid side fire bar
  • Crystal clear colour screen with options
  • Tremendous battery life
  • Decent amount of vaping modes
  • Refreshing lack of LED lights
  • Firmware upgradeable
  • Included tank better than many stock tanks
  • Not a bad price


  • A little on the heavy side
  • Might be a bit blingy for some

Final Review Verdict

This is definitely a vape kit I’d probably scroll past while vape shopping on line but trust me in the flesh this one ain’t half bad.

However whilst the TFV12 Prince is a pretty good stock coil sub ohm tank it’s not to my taste and I kind of think it dwarfs the Devilkin looking slightly top heavy as a kit.

However popping on one of my atties with a bit of gold in them and the Devilkin certainly pops that bit more.

Obviously with a choice of colour combos the world’s your oyster if like me you love a bit of matchy matchy lol.

devilkin size comparison

I’m only looking at the mod in depth in this review and have to say I like this one – never thought I would from the photos – but it’s a solid build and performer and really does feel great in the hand.

Nice one Smok though as to innovation – it’s not really anything new design or chip wise…

If this was an end of school term report I’d use the immortal words “a start but still could do better” 😉

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.


  1. I have a freemax tank and coil on my devilkin currently it shows a max of 70w on the coil everyone says that seems low but it works flawlessly so far

  2. New to vaping, really trying to quit smoking. I’m trying to figure out what type of coils I can order for this decilkin vape. Can I use any replacement coils I find online or do I need specific ones. Any help would be greatly appreciated.

  3. I have been having problems with mods with stamped connectors on the top. After a month the connector pulls up and you can’t screw down the tank anymore so it would be nice if reviews addressed this issue.

  4. My mod says “ohms too low” after I changed the coil. Didnt give me the new coil option. I know how to adjust the ohms but that’s not doing anything. HELP!

    • Hey Matthew,

      Try the suggestions here that SMOK advise –

      Personally I have found the following to work 95% of the time:

      – Ensure coil is screwed in properly
      – Take the tank apart, clean and re-seat coil. When taking apart take a look at the point below.
      – Ensure the pin (in the base of tank) that makes the connection between mod and coil is actually making that connection.
      – Finally, it could be a faulty coil. Try a new coil to see if the issue continues.

      Let us know how you get on!

    • Hi Brenna,

      To get to the colour settings on screen you need to do the following

      – Click fire bar 3 times to enter menu
      – Quick press the fire bar to scroll through options
      – When you reach colour settings use the small function buttons to select preferred colour.

      Hope that helps.
