Caliburn A2S by Uwell

Select one of the following

The Uwell Caliburn A2S is an easy-to-use fixed-coil pod kit with flavour-enhancing technology for great taste. 

Uses Caliburn A2 pods.

  • FREE E-LIQUID (Choose when you add to basket)
  • Up to 15W no-fuss automatic output
  • Convenient fixed-coil pods
  • Flavour-enhancing Pro-FOCS technology
  • Easy inhale firing
  • USB-C fast charging (cable sold separately)

Part of the popular Caliburn Series, the Caliburn A2S is a super easy-to-use and beginner-friendly pod kit. To get started, you simply fill and attach the pod, wait a few minutes and then inhale on the mouthpiece to start vaping.

The buttonless device outputs up to 15W and requires no settings - the power output is automatically set depending on the pod being used.

Caliburn A2 pods feature a convenient fixed coil and utilise Uwell's Pro-FOCS technology to create a flavour-filled Mouth-to-Lung (MTL)

The convenient fixed coil means there is no need for manual coil changes. When the coil inside the pod runs out you simply replace the whole pod.

For other devices in the Caliburn Series, see the Caliburn, Caliburn G, Caliburn G2, Caliburn A2, AK2 and GK2 devices.

Compatible E-liquids & Pods

The Caliburn A2S works with fixed-coil Caliburn A2 pods and is recommended for use with VG:PG 50:50 e-liquids and nicotine salts.

Who is the Uwell Caliburn A2S kit for?

The Caliburn A2S is suited to users of all experience levels looking for a compact MTL pod device. Its easy-to-use features like fixed-coil pods, automatic power output and inhale firing make it particularly suited to new users as a starter kit.


What e-liquid can you use with the Uwell Caliburn A2S?

The Caliburn A2S is recommended for use with VG:PG 50:50 e-liquids and nicotine salts.

Is the Caliburn A2S a Mouth-to-Lung device?

Yes. The higher resistance coils in the Caliburn A2 pods make it perfect for Mouth-to-Lung vaping. See MTL v DL for more information.

Can I charge my Uwell Caliburn A2S overnight?

Lithium batteries should not be left unattended when charging. It is also important to use an appropriate charger, such as the Veho Plug Adaptor. For more information see our battery safety infographic.

How long do Caliburn A2 pods last?

The key element to how long a pod lasts is the coil inside the pod. Coil life depends on a number of factors such as how frequently you inhale and how long you inhale.

However, you can maximise the life of the coil by allowing the e-liquid to soak in before using it for the first time, by using e-liquid with the correct VG:PG ratio and by keeping the pod topped up. With care, the pods should last anything from a few days to a week or more without needing to be replaced.

Product Care

Follow these simple steps to get the most out of your vape kit.

  • For refillable devices, allow e-liquid to soak into the coil for at least five minutes before using the device.
  • Always keep some e‑liquid in the pod or tank to ensure the coil is saturated.
  • If using replaceable coils, push/screw them in firmly but don't over tighten.
  • For adjustable power devices, use recommended power settings for the coil or pod you are using (see box, coil or manual).
  • When device is switched on, only press fire button when inhaling. This prevents condensation build up in the pod or tank.
  • If using a refillable kit, use the correct e-liquid for the coil or pod you are using. See the product description for each kit for recommended e-liquid types
  • Avoid filling refillable pods or tanks above the fill line or to the very top.

Battery advice

  • Charge batteries on a flat, hard surface.
  • if device comes with an on/off switch, turn off when not in use.
  • Keep battery terminals clean. A quick swab with a cotton bud can improve performance and reliability.
  • Always keep some charge in your battery.


  • Use damaged batteries.
  • Leave charging batteries unattended.
  • Allow contact between your batteries and water.
  • Carry batteries in a pocket/bag with coins or keys.
  • Expose batteries to sunlight, extreme heat or cold.
  • Allow batteries to go to zero charge.
