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 0.9Ω 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.
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.

Follow these simple steps to get the most out of your tank.
- When filling, always avoid getting e-liquid in the centre tube.
- Don’t hold down the button before inhaling.
- When attaching the coil, screw it in firmly but don’t over-tighten.
- Make sure you use the right power settings. If unsure, check the manual or start with a low power setting and work your way up till you get the right hit.
The Right and Wrong Ways to Treat Batteries!
Battery Safety Information
- Ensure you use the correct charging equipment for your e-cig (see below).
- Charge batteries on a hard surface.
- Turn your battery off when not in use.
- Use damaged batteries.
- Leave charging batteries unattended.
- Allow contact between your batteries and water.
- Carry in a pocket with coins or keys. (The Kbag is a great way to carry batteries securely and safely).
- Expose your battery to sunlight, extreme heat or cold.
For more information see our E-Cig Battery Safety Infographic.
Recommended Charging Equipment
We recommend the Veho Plug Adaptor and the Nitecore Intelli charger (for external batteries). Both are high quality devices from a reputable manufacturer, have performed well in testing and have the right voltage output for e-cigs.
Extending Your E-Cig Battery Life
With regular usage, your e-cig battery will usually last for 3 months, although they can last longer. The following steps can help extend the life of your battery
- Cleaning your battery terminal. The most effective way to do this is to use a cotton swab soaked in alcohol, but you can also clean it with a tissue or a cotton swab.
- Keeping your battery charged. Keeping some charge in your battery can extend your battery life, especially if you go for some time without using it.
How To Maximise the Life Of Your Coils
Always allow your e-liquid to soak into your coil for at least five minutes before using it. This will help prevent your coil from burning out.
When you have a more powerful coil, or one with more wicking material, it’s also a good idea to prime it by applying a few drops of e-liquid into the coil holes before filling.
Once you’re using the device, it is important to keep your tank topped up. If the e-liquid gets too low and the coil is exposed, the coil can burn out.
