The Uwell Caliburn A2S pod kit is a sleek and stylish choice for vapers of any exerience level thanks to it being so easy to use. Powered by a 520mAh built-in battery, you can vape longer between charges. Each kit includes two refillable 1.2 Ohm Caliburn A2S pods, that are ideal for creating an MTL (Mouth To Lung) inhale.


  • 520mAh Built-In Battery
  • Fixed 15W Power Output

Thanks to this kit's buttonless design and inhale activation technology you can vape by simply puffing on the mouthpiece. This kit also uses a fixed wattage to deliver consistent and discreet MTL vapour production from first to last puff. There's also a small window built into this kit too, so you can see how much e-liquid is left in the tank.

The 1.2 Ohm Caliburn A2S pods that are included with this kit allow for quick refills and less mess. They features a side filling port that can easily be removed to top up with your favourite e-liquid. The coil is built into the pod, which means you won't have to change any fiddly coils. For the best results, we recommend pairing these pods with 50/50 and high PG e-liquids.

Please note: this kit is not sold with a USB-C charging cable.

Disappointed (30 April 2024)

Leaks, Cool burns quickly and causes extreme distaste in eliquid. Lasted 2 days before it all went wrong.

By Hazel from Norfolk

Decent vape! (08 January 2024)

I’m impressed with this vape, and having had the Koko & the model prior or after this one (I forget which it was) before, this one, I’m happy with it.

Pros: lightweight, sleek, great choice of colours, no activation button on the front, it lights up as it charges and the tank you get is a decent size.
Cons: I would’ve preferred a top fill tank but this is minimal as I’m sure you can get others that do and you have to supply your own charger.

Overall I’m happy with this vape, like that it’s minimal simple MTL and there’s a window which, when you inhale, shows the ‘Caliburn’ sign light up, the standard green - full charge, blue - half way, red - dead. Will buy again if I need to!

By Laura

Intermittently working (26 June 2023)

I tried this because the disposable vapes are so expensive. It seems to be intermittently working. Sometimes there is nothing when you puff on it and other times it works fine. It's not awful but I'd definitely prefer a disposable vape. It looks nice and is easy to use.

Still leaks (12 June 2023)

Still leaks - pods are just not up to scratch at all. The original Caliburn is far more superior which is a real shame and still no improvement on battery with the same old 695 mah

By Lou from England

Very good (06 June 2023)

I usually use disposable vapes until my friends recommend this one and so far so good! Charging lasts a vile and not too harsh on the throat!

By Ben from United Kingdom

Really Impressed (14 May 2023)

Bought as an alternative for disposables and its just that, super easy to use and refill, battery lasts a long time and the pods are pretty cheap and easy to swap out, cant say im disappointed

By Rebecca from UK

This is excellent (11 April 2023)

I really like this its small discrete and such an incredibly simplistic design which I love. So easy to just change the pod which seems to last forever. the battery life is also good and it has a handy indicator so you know how much charge is left. its auto draw and the flavour and vapour production are good. charges with a C cable (not included) but if you're like me you'll have loads of them hanging around the house it fully charges in a very short time as well. i like this so much I've repurchased it for my hubby, son and daughter-in-law.

Caliburn a2s (07 January 2023)

A great vape pen, works just like a disposable.
Better then the single use elf bars and is easy to refill.
Would recommend to any new users who are put off by the idea of fiddly coil changes.
Quick to charge with a USB c and comes in a great range of colours

By Pablo

Not powerfull and no air flow (02 December 2022)

Really bad experience. The air flow its really small that you can't feel that you are vaping, and its not powerfull enough, so basicly you make really small puffs with no taste or cloud.The batery leds and designed on that way that you cant see easy how much battery have still remaining, and the batery is not enough for a whole day. Its much much better to get the Caliburn G2

By Chabz from London

CaliBURN (08 October 2022)

My first open pod upgrade from a closed pod JUUL2 and Vuse device, and I love it.

Cool design, plenty of colours to choose from, I went for the blue and green.

Battery is great and charges quickly with a USB C cable, not included with the device. The battery indicator which is a light up caliburn logo is just so clever.

Easy to refill side filling pods, haven't noticed any leaking, and the 1.2 coils last well. Still on the first one after 3 weeks of moderate vaping.

Overall well happy with my first caliburn!

By Martin from Suffolk

Prefer the old pods... (27 September 2022)

The new device is nice and works perfectly. The light up part is much easier to see to keep an eye on battery life and charging. It feels overall very similar to the A2 device, minus the battery, which personally I prefer.

The pods though...I'm not sure. The side filling is kind of nice, as sometimes the old pods were quite hard to open. The shape is fine...but I don't feel like they vape quite as nicely as the 0.9 ones. They aren't as 'smooth' of that makes sense?

Overall, if your A2 is still working fine, there's not a huge amount to upgrade too. You can use the old pods in this device no problem which is handy, and probably what I will do in the future.
