Caliburn A2 by Uwell

The Uwell Caliburn A2 is a sleek & slim beginner-friendly pod device with easy-to-use features including convenient fixed-coil pods, bypass output & inhale firing.

Uses Caliburn A2 pods.

Also see the Caliburn A2S.

  • Free E-liquid (Choose when you add to basket)
  • 15W auto output
  • 520mAh battery
  • Convenient fixed-coil, top-filling pods
  • Specially-designed MTL mouthpiece for comfort
  • Manual & auto draw options
  • USB-C fast charging (cable sold separately)

Part of the popular Caliburn Series, the Caliburn A2 improves on the original Caliburn device with increased power output but keeps the sleek, slim design and easy-to-use features that make it a perfect device for new vapers.

The Caliburn A2 has a simple, single-button design and uses bypass output - automatically selecting its output depending on the battery capacity. This takes the guesswork out of wattage selection and means there is no need to fuss with settings. (See more about Bypass mode in the FAQs below.) The fixed 520mAh battery can be quickly recharged with a USB-C charging cable (sold separately).

You can choose how to use your Caliburn A2 with the choice of both manual and auto draw options. Either use the button to fire the device or simply inhale on the mouthpiece to activate it.

The Caliburn A2 uses fixed-coil 0.9ohm pods suitable for Mouth-to-Lung (MTL) vaping. Caliburn A2 pods have also been designed with a specially-shaped mouthpiece to suit this vaping style.

The pods simply click into the device thanks to a simple magnetic connection and a clean and easy top-filling design means there's no need to remove it to refill. A handy viewing window allows you to keep tabs on your e-liquid levels to prevent the pod from running dry. The fixed-coil design of the pods also eliminates the need for coil changes, when the coil runs out simply replace the whole pod.

For other devices in the Caliburn Series, see the Caliburn G, Caliburn G2, AK2, GK2 and A2S devices.

Recommended E-liquids

Caliburn A2 pods are recommended for use with VG:PG 50:50 e-liquids.

Who is the Uwell Caliburn A2 for?

The Caliburn A2 is a perfect device for new vapers who want a fuss-free and simple MTL vape that requires little setup or maintenance.


What e-liquid can you use with the Uwell Caliburn A2?

The Caliburn A2 pods work best with e-liquids with a 50:50 VG:PG ratio.

What is bypass power?

Bypass power delivers the full power of the battery to the coil without being moderated by the chipset. This means power output will be higher when the battery is fully charged and lower as the battery level drops. See Advanced Vaping Modes for more information.

Can I charge my Uwell Caliburn A2 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.

Is the Caliburn A2 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.

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.
