Uwell Caliburn A2S
The Uwell Caliburn A2S is a slim and lightweight pod system designed for daily use, featuring a 520 mAh built-in battery, maximum 15W output power, and a 2 ml capacity cartridge.
With a body weighing approximately 30 grams, it can be easily carried in a pocket or bag.
The device features no fire button. It is operated simply by inhaling through the mouthpiece, thanks to the automatic draw system activated by the air sensor.
This simple design provides convenience for users who do not want to deal with menus and wattage adjustments.
Pro-FOCS flavor adjusting technology and mesh heating structure help deliver e-liquid flavor in a balanced way.
The fixed airflow is tailored to the mouth-to-lung usage style known as MTL.

How to Fill the Cartridge?
1. Remove the cartridge from the device by pulling it upward.
2. Open the silicone filling plug on the side of the cartridge.
3. Add e-liquid through the filling slot without overflowing into the air channel.
4. Fully close the silicone plug and place the cartridge back into the device.
5. Wait 10-15 minutes before using a new cartridge for the first time.
Suitable E-Liquid Selection
The 1.2Ω and 0.9Ω cartridges of the Caliburn A2S are designed for MTL usage.
For the most balanced wicking, 50VG/50PG salt nicotines or regular e-liquids suited for low-wattage usage can be chosen.
Very thick e-liquids with high VG ratios can slow down cartridge wicking and cause dry hits.
⚠ Charging information: Charge the device's USB Type-C port using a quality, undamaged cable through a suitable 5V USB power source. Do not charge the device in an excessively hot environment, unattended, or on a flammable surface.
