The Uwell Caliburn A3 pod kit is ideal for vapers that are looking for a device that’s easy to use. It has a built-in 520mAh battery, which can output up to 13W of power and means there’s no need to worry about purchasing any extra ones. You’ll also find two 1.0 Ohm pods in the box, which have a 2ml capacity and are ideal for delivering an authentic MTL (Mouth To Lung) inhale.


  • MTL Refillable Pod Kit
  • 13W Max Power Output
  • 520mAh Integrated Battery
  • Inhale Activation
  • 2ml Refillable Pods
  • Built-In Coils

Because it features both inhale activation technology and a standard firing button, you have a choice in how your vape works. All you need to do is simply inhale on the mouthpiece of your Caliburn A3 to activate it. However, pressing the button also works, if you prefer a more traditional way to vape. Once activated, it’ll produce an MTL inhale with a discreet amount of vapour that mimics the feel of a cigarette.

Topping up your kit has also been made very easy to do. Simply removing the mouthpiece from the Caliburn A3 pod reveals the filling port, allowing you to add the e-liquid of your choice. Though you’re able to use any e-liquid with this vape kit, we’d recommend pairing it with either a 50/50 or high PG e-liquid to get the best results.

Please note: This kit does not include a USB-C charging cable.

How do I activate this kit?

(15 Jun 2023)

Thanks to a combination of button activation and inhale activation, you’re given a choice of vaping at the click of a button or just inhaling on the mouthpiece. This keeps things simple and means that you don’t have to waste any time fiddling around with lots of buttons and menus. Whichever way you choose to vape, the Caliburn A3 will create a small amount of vapour for an authentic MTL (Mouth To Lung) inhale that replicates the feel of a cigarette.

What vape juice should I pair with this kit?

(15 Jun 2023)

Due to the resistance of the included coil, the Uwell Caliburn A3 vape kit will work best with 50% VG e-liquid and higher PG options. 

Does the Uwell Caliburn A3 include pods and coils?

(15 Jun 2023)

The included Uwell Caliburn A3 pod contains a built-in mesh coil, which heats your e-liquid up at a fast rate for improved flavour. The built-in coil design of the pod is useful if you’re looking to cut down on maintenance and messy coil replacements. 

What power output can this kit deliver?

(15 Jun 2023)

The Uwell Caliburn A3 vape kit is capable of delivering up to 13W of power, making it a solid choice for MTL (Mouth To Lung) vapers. This means that you’ll want to pair it up with a 50/50 e-liquid or nic salt.

How powerful is the Uwell Caliburn A3 battery?

(15 Jun 2023)

The Uwell Caliburn A3 vape kit is powered by a built-in 520mAh battery, which should support plenty of vaping time before needing to recharge, which takes just 15 minutes — thanks to USB-C fast charging.

My go to (14 April 2024)

I’ve had a handful of these A3 Caliburns. When one dies I get another. I can’t get over the simplicity and pretty much everything about it. The ease of refilling it, the battery life, the weight, the feel of the vape itself, the price and I’d say it’s my go to device. I’ve purchased other makes and models but I always have an a3 to hand. The battery depletes after about 6month which is normal for vape devices and at this price it’s not even worth stressing about getting a new one.

By Janey from Kent

Great vape kit (31 March 2024)

This is my second purchase of this vape kit bought as a spare for when I’m charging the other.
Much better vape than the A2 caliburn, I’ve had no leakage from the pods so far. Battery lasts longer too so less need to charge. Big shout out to the staff at Vapeclub for ensuring my delivery reached me on time, I was surprised to receive it today on Easter Sunday. Thank you so much.

By Charley from Bridgend

Love these vapes (25 February 2024)

Love these kits from uwell, the vapes are super slender, hold a good amount of liquid and super easy with the charging functionality. I love the light system so you know when to charge and the ability to switch between button drag. Really great kit

By Stu from Edinburgh

Great kit (12 February 2024)

Another good kit from Uwell. This is the type of one that if you wanted to just have one device and keep things simple, you would pick it! Battery could be better but the fast charge makes up for it

By Clare

really good (09 February 2024)

first refillable vape i’ve got and i have no complaints! quick charge and charge lasts a while if you turn it off when not using. pods are easy to use and haven’t really had an issue with leaking.

By Jt from Merseyside

Good quality great value (27 November 2023)

Massive step up from previous vape kit used.
Great value. Brilliant performance. Great battery life. Easy to use.

Just be careful not to spill the eliquid on refill, it can cause the button to stop working but inhale still works so still use able even when button not working.

By Ben from London

Very happy (14 July 2023)

Less leaky than the A2 and better overall design. Wasn’t a fan of having coils and pods separate when I used the G series so I made the switch to the A2. The A3 is a decent improvement.

By Cat from Glasgow

C3 Pod (27 June 2023)

This is a Lovely design, fast charging and reliable. Gives great flavour Really happy with this one.

By Nick from Woking

Better than the A2, but still not great (31 May 2023)

The A3 is certainly an improvement on the A2. Mainly because it's not as leaky. But the flavour and coil/pod life still isn't as good as their G series

By Kezaroo89 from Hertfordshire

great vape (15 May 2023)

after looking for a while i came across this one , reviews were good so decide to buy . it is a great vape helped me to stop smoking stright away , im ordereing another one so when one is on charge i have the other . would highly recommend this vape

By Moanyvaper from Hertfordshire

Great big of kit (26 April 2023)

Im in my second one of these, first one just gave up but its getting heavy usage and charged multiple times a day! They are great, burn 70/30 juice perfectly too, great taste and cloud production, coils last ages! Well over a week! I use a sub ohm device too but seriously wouldn’t be without this hence buying another! Also absolutely no leaking at all, nice to hold and discreet.. 10/10 uwell..
vape club on point as always too..

By Noghri from Nottingham

Discreet & easy (09 April 2023)

Great little vape. Perfect for a discreet vape without a Mod in your pocket. Less waste than the disposables. Easy to fill and I have had no leaks. Fast charging too. Pods last about a week depending on usage. Got a second one for my partner.

By Dan from Brighton

Amazing (03 February 2023)

Lovely design, fast charging and reliable. Really happy with this one

By MUSTAFA from Aberdeen

worth to use it all day (31 December 2022)

Good quality, I have used it for over a week with the original coil and the most important thing is no leak or liquid comes through while you vape.
I used to use VAPORESSO XROS 2 and I can tell the taste has been reduced when using UWELL CALIBURN A3 but as I said above no leak at all.
coils are still good I finished 20 ml so far on one pod and still vaping with no issues yet

the only negative thing is I wish they made the battery bigger

By Ross from North Wales

A3 is very good (13 December 2022)

Just tried it for 1 day but my early impression is that it’s a great vape , nice to hold and a great taste with the new riot salts , 10 out of 10 for the price

By Nev from London

Tremendous. (09 December 2022)

This is the one.

If you're like me and you kept coming back to the OG Caliburn because all the other pods weren't doing it for ya. Then this is the one. The flavour, pod longevity and ergonomics of this pod are top notch.

By Greg from Bristol

Great upgrade! (02 December 2022)

Bought as a second device to my A2 and must say it is a great upgrade.
Good quality and long-life coils (pods). No leaking.
