The letter “A” is derived from the Greek letter alpha, and the Caliburn A series comprises devices that are easy to operate and appropriate for novices. The Uwell Caliburn A2 follows in the same footsteps. The Caliburn A2 is more like the original Caliburn, with refillable pods and a fixed coil, as well as a slew of other upgrades that we’ll go over next.

Design and Build Quality

The Caliburn A2’s small dimensions and lightweight make it ideal for on-the-go vaping sessions. The Caliburn A2 design was improved by flattening and polishing the device’s body to eliminate rough edges and make it more comfortable to grip. It has a metallic appearance and is lightweight but not flimsy. An ejuice window on the device’s body allows you to conveniently monitor your ejuice levels without having to pull out the cartridge. 

The Uwell Caliburn A2 features both a draw-activated and a fire-button mechanism, so you won’t have to modify your vaping method regardless of the device you’re switching from. The device’s fire button is on the top and is reasonably responsive. The mouthpiece is located at the top of the device and is substantially slimmer than the original Caliburn G’s. The mouthpiece also has a lip-fitting drip tip, which MTL vapers will like because it provides for a more comfortable drawing experience.

Battery Capacity

The 520mAh rechargeable battery incorporated in the chassis ensures that the device may be used for extended periods of time. It can also produce up to 15W of power. The Caliburn A2 is charged via a Type-C connection on the device’s bottom. According to Uwell, it can charge to 90% capacity in 35 minutes. The device has an LED light near the bottom of the front that serves as a battery indicator:

  • Green: 60-100%
  • Blue: 30-60%
  • Red: 0-30% 

Caliburn A2 Ejuice Pod

The Uwell Caliburn A2 Pod Kit includes a cartridge that can be used with either nicotine salts or freebase nicotine ejuice. The pod is held in place at the top of the A2 body by a non-wobbling magnetic connection.

Uwell kept the previous Caliburn’s convenient top-fill design, so all you have to do to remove it is slightly push the mouthpiece on the flat side. The pod also has a small vent port that allows air to escape while it is being filled, preventing the formation of unsightly airlocks.
