Small, square, and stylish — the Uwell Caliburn AK2 is a slim 15W pod system with a 520mAh battery and a liquid viewing window so you always know when it’s time to refill.
What Is the Uwell Caliburn AK2?
The Caliburn AK2 is a rechargeable, refillable pod system — the device is charged and reused, while the 2ml pod is topped up with your own e-liquid rather than replaced whole. This makes it a more economical, longer-term option compared to disposable vapes for daily vapers. See our disposable vapes buying guide for a full comparison.

Combined with an e-liquid viewing window, it’s a practical, low-maintenance pick for vapers who want a straightforward MTL device without adjusting settings.
How to Use the Caliburn AK2
- Charge fully via USB Type-C before first use (~1 hour).
- Remove the mouthpiece and top-fill the pod with e-liquid.
- Insert the pod — the magnetic connection secures it in place.
- Check the e-liquid viewing window to monitor remaining liquid.
- Simply draw on the mouthpiece to activate — no button needed.
