The Uwell Caliburn AK2 pod vape kit is one of the most compact kits on the market. Simple to use, it creates a small amount of vapour for an MTL (Mouth To Lung) vape. Powered by a built-in 520mAh battery, it can last up to a full day on a single charge and is very slim. The ideal option for new vapers or anyone looking for a simpler vape, each kit comes complete with two Caliburn A2 refillable pods to help you get started.


  • Slim Refillable Pod Kit
  • 520mAh Built-In Battery
  • Fixed 15W Power Output
  • MTL Vaping
  • Inhale Activated
  • 2ml Refillable Pods
  • Built-In Mesh Coils

Thanks to inhale activation you won’t have to deal with menu systems or screens. Instead, you can start vaping by inhaling on the mouthpiece. Designed to deliver a vape that feels closer to a cigarette, this kit produces a smaller amount of vapour for an MTL inhale. The fixed power output of this kit also means you’ll experience a consistent vape - even as the battery runs down.

The A2 Caliburn pods can each hold up to 2ml of e-liquid and there’s plenty of options for you to choose from. Uwell has designed a new top-filling mechanism that makes refilling simpler than ever. The mesh coil inside each will deliver better flavour from e-liquid and is long-lasting. You won’t need to worry about messy coil changes, you can just replace the pod. When it comes to e-liquid we recommend a 50/50 or high PG e-liquid.

Please note: It doesn't come with a USB-C charging cable. Also, the Caliburn AK2 can not be used with the original Caliburn pods or Caliburn Koko pods.

Broke.. (04 November 2023)

Disapointed. Was recommended this by someone at work.
It broke really quickly, luckily Vape Club were lovely and sent me a new one (I made sure to take evidence it wasn’t working and sent this to them).
I was just a bit disappointed and underwhelmed

By Anonymous

Underwhelming (25 September 2023)

Same great taste as with all the caliburn line but I found the pods to be loose and the auto draw was not always working

By Keiran from Manchester

Best Vape I've tried (09 July 2023)

This Vape has the perfect balance of flavour and throat hit. No nonsense, just charge and go. The selection of colours helps give you your own personalisation. Time will tell how it holds up but I dropped it in a drink last night and it still survived so I'm hopeful.

By Sam M from London

Great pod, but doesn't last long. (10 May 2023)

I have had 2 of these since January this year (2023) and yeah they are great. They do leak a little and the pod mouth pieces tend to break.

I do like them but refuse to get another. Having had 2 they have both after a month or so developed the same issue. When inhaling in struggles and half the time you get no vapor. Not sure if i use to much or what but both with the same issue. Wouldn't be so bad if there was a firing button but since there isn't pretty much makes them unusable.

Sadly wouldn't recommend.

By Ce from England

highly recommend (23 January 2023)

Very good, especially at price point. only issue is coils burn a little too fast relative to other vapes i’ve owned.

By Smash from South East

Major Leakage (19 December 2022)

I was recommended this product by my neighbour however I've major problems with leakage. Vape club have been amazing in providing replacements however it generally leaks all the time. I would not recommend this product.

By Niall from Newcastle

Stealthy lil thing (28 November 2022)

Absolutely banging vape, had it 6 months now and she's still going strong, only downside is the pods leak every now n then if you've dropped it a few times, I believe you can purchase new pods through amazon with this new 'anti-leak' tech although 2/4 of the pods I bought through them ended up leaking pretty quick; would b a solid 10/10 but pods r pretty annoying so for that reason it she gets a 9/10

By Luka from Montenegro

Caliburn excellence (23 November 2022)

Yet another top-class device from the Caliburn series. A proper and rich MTL with a hard kick, slim and light almost to the point of non existence. Now they need to fire somebody from the marketing department who decided to write "keep on keeping on" on the device and it will be perfect. One star less for that.

By Anonymous from Essex

(25 October 2022)

I've been vaping for years and had many devices I decided to buy two of these so that I had a spare rolling over,don't bother,both leak like a sieve and sometimes fires and doesn't stop leading you to quickly release the pod.

Bad experience with these so onto the next one.

By Mr E from Midlands UK

Nice MTL Vape (16 October 2022)

Super compact, but packs a nice hit, battery lasts all day and only takes 30mins to charge. Best pod kit I have tried so far, really good flavour from the liquids. Love it!

By Dan from Gl1

Amazing (03 October 2022)

Absolutely blown away by this device. So small & perfect for stealth vaping @ work. Great flavour. Auto draw on point every time. Highly recommend

By Harry1204 from Hertfordshire

Great little vape (29 September 2022)

Really handy sized vape and delivers a pretty good output for what it is. Very simple in design and changing pods is fool proof. Only downside would be the the pods and can leak into the chamber where they sit and if liquid get on the metal components it can require a clean as there is a auto shut off function. Make sure you have a USB C charger as they do not come with one but very similar feel to a cigarette and it was this vape that stopped me from smoking

By Louis from Norwich

Amazing little device. (29 September 2022)

My partner had the pink one and unfortunately it went In the washing machine so I've ordered another one. These give out good flavour and have plenty of battery life. Pods last a very long while, my partner doesn't vape too often like me so her pods could last up to 2 weeks.

By Dan S from Leeds

Great way to replace disposables (04 August 2022)

I've used many vape devices in the past, from big to small. But none of them worked for me so I've always been a frequent buyer of disposable vape devices for the convenience of the small size and the great flavour they give along with no leaks.

I tried a few pod devices from other brands and none worked for me until I was recommended this, I couldn't be happier. The A2 pods have by far the best taste from any other brands I've used, the device is tiny (I keep mine in my card holder) the battery for such small size easily lasts me a day, and if not this device charges to full in 30 ish minutes and most importantly I haven't ran into any leaks. Having this paired with the Bar Juice 5000 nic shots it tastes just as good if not better than most disposables. It produces decent sized clouds for when you are at home but can also be stealth vaped when out in public.

I can't recommend this enough.

By Lewis

It’s ok but not for me. (01 August 2022)

This is great for being pocket friendly and looks good but that’s where it stopped for me. I found the pod to be loose when clipped In, the auto draw didn’t work very well unless I covered the air hole with my finger and the battery didn’t last 5 mins. I’m sure this is perfect for some people but after using the other caliburns I would defo recommend sticking with button fire at the very least.

By AJ from Walsall

Brilliant Product (16 June 2022)

This product is bang on, its so smooth its a nice size to carry around and a really good bit of kit very easy to use and fill, only downfall doesnt come with charger but that doesnt effect the rating at all for me.

By Dee from UK

Perfect little kit! (24 May 2022)

This vape is perfect, better than disposables and of course a lot cheaper in the long run! The vape allows for a really great flavour of any e-liquid you choose, really easy to fill up and surprisingly, the 2ml tank of liquid lasts quite a while (and that’s coming from a chain vaper!)

100% recommend this :)

By Louby from Oxford

Compact & easy to use (29 April 2022)

Very small and lightweight, perfect pocket size.
Very easy to refill, pop the top off the pod and the liquid goes in through the top.

By Milly29 from Hampshire

2nd purchase (19 April 2022)

Bought another as unfortunately the last one got dropped in the sea! Was so pleased with the first though that decided to get the same one. So easy to use with the pods and have yet to find a juice that it doesn't like.

By Adam

Great Vape (22 March 2022)

This is very good product, no leaking, easy to use, good hit. Great value for money!
