The Uwell Caliburn A3S pod vape kit is an ideal choice for those looking for an easy-to-use and pocket friendly device, no matter their level of experience with vaping. It delivers a discreet amount of vapour for an MTL (Mouth To Lung) vape, thanks to the fixed 16W output and the built-in 520mAh battery lasts most vapers all day.


  • 16W Fixed Output
  • 520mAh Built-In Battery
  • 2ml Refillable Pods
  • Side Filling Design
  • Inhale Activation
  • Built-In Coils
  • USB-C 2A Fast Charging (Cable Sold Separately)

Using your Caliburn A3S couldn’t be easier. Simply insert a filled pod and inhale to vape. The buttonless design keeps things simple – there are no menus or settings to worry about. Plus, colour-coded LEDs display your battery power level, and when it’s time to recharge this can be done quickly using a USB-C cable.

The Caliburn A3S pods are simple to refill, with a mess-free side-filling design. Just pop open the stopper on the side of the pod to access the fill port. The pods feature a built-in coil which means there’s no need to worry about fiddly coil changes. You’ll have a choice between 0.8 Ohm and 1.0 Ohm coils, both of which feature a mesh build for improved flavour. When your coil is finished, simply replace the whole pod. These pods work best when paired with e-liquid that’s at least 50% PG, whether you prefer freebase or nic salt vape juice.

Please note: The Uwell Caliburn A3S kit does not include a USB-C charging cable, but you can buy a USB-C Cable separately.

Great vape (11 May 2024)

Had it for a couple of months now. Very happy with it. I was looking for a compact vape that works well and this did the trick. No spills. Slim and lightweight, fits in your pocket like a lighter. Definitely recommend!

By Cal from London

Great Vape... (29 November 2023)

First venture into refillable pod vape world and after reading reviews, decided to go for this one.

Was not disappointed! The one slight gripe is that my pods seem to leak a little over time

By Puff

Great device. (13 November 2023)

This is my first refillable pod kit and I'm impressed. I love the simplicity of it. No buttons, easily filled pods that last a long time. You get a lovely smooth vape from it and the feel in the hand is perfect too.

By Mel from Shetland

Got husband off the fags (28 October 2023)

This got me to stop smoking cigarettes after using disposables. I never expected it would do the same for my husband!!
Pros: practically the same as the disposables in terms of flavour and throat hit, but it’s refillable. It charges incredibly fast and you can still use it while it’s charging. Easy to refill. Withstands a lot of dropping on the floor.
Cons: liquid leaks a little if you puff while laying down. I wish the pod was a bit bigger and held more liquid than 2ml.

By Crisable from Sheffield

Great vape but the pods leak (09 October 2023)

Like the fact that the caliburn logo flashes through when it charges and is totally lit once charged. Unfortunately the pods leak!

By J from UK

Caliburn A3S Midnight Black & Lake Green Kit (09 October 2023)

I purchased a Midnight Black & Lake Green.

Comes with a 0.8 & 1.0 Ohm Mesh Replacement Pod. I prefer the 0.8 - have a read of DTL and MTL vaping methods to work out which is better for you.

No issues, would happily buy again.

By Ahu381 from London

Best starter kit I've had so far (29 September 2023)

Like the Caliburn G2, this burns liquid to deliver a great tasting vape. Unlike the G2, this is lighter and hasn't leaked on me yet. Battery isn't the greatest, but gets me through most of the day and charges super quick. It is great for those who want a reliable, lightweight, easy to fill and great tasting vaping.

What's more, Vapeclub have fantastic customer service and super quick delivery. I wouldn't buy from anywhere else!

By Joe from Kent

Another quality product by Uwell (23 August 2023)

Have been using the Caliburn since the OG device, some have had leaking issues however the A3S is a brilliant all rounder. Super quick to charge, lightweight, and great flavour.

By LJC from Watford

Top quality (21 August 2023)

Always used caliburn devices and this one is the best. Has the option of a 0.8 coil witch produces 16W or a 1.0 for 13W
Big wicking holes, can easily handle a 60/40 20mg salt.
Battery is sturdy just like the A2S and holds the same charge.
Quick charging around 25 mins from flat.
Downside is no compatibility with A2S pods but pods/coils have definitely improved alongside any aesthetic changes

By Kali from Midlands

Best No-Smoking experience (18 August 2023)

I have tried a number of Caliburn vapes and this one by far is the most well behaved vape. So far- no leaks, coil retains flavour and the battery lasts long with moderate use. The pods magnet design is well thought and actually works. Highly recommended if you want an easy going, reliable vape on the go!

By Ross from England

Great first vape (13 August 2023)

This is my first refillable vape, as someone who used to bounce between cigarettes and disposables. I've used it for around 6 weeks now. The vape itself feels sturdy in the hand and is easily pocketable. The battery lasts me a whole day (I go through about a pod's worth of liquid a day) and charges up quickly. Only 9/10 because the pods that came with the kit seemed to burn out very quickly - might have been a dud set, since I bought the refill pods and those are much better, no burnt taste after a day and last for weeks before losing flavour. Would recommend!

By Paul from Scotland

Best since the original G (23 June 2023)

Arrived today and I already feel the same as I did with the original caliburn g , no button so won't go off in pocket which personally was a problem for me at work (in a forklift) definitely recommend!
