How to Refill the Caliburn A3 Cartridge?
1. Remove the cartridge from the device.
2. Take off the black mouthpiece by pushing it sideways.
3. Add e-liquid through the colored filling port; do not fill e-liquid into the middle air channel.
4. Firmly snap the mouthpiece back onto the cartridge.
5. Wait 10-15 minutes before using a new cartridge for the first time.
Suitable E-Liquid Selection
The 1.0Ω cartridge of the Caliburn A3 is designed for MTL use.
For the most balanced e-liquid wicking, 50VG/50PG salt nic or regular e-liquids suitable for low-wattage MTL usage can be preferred.
Thick e-liquids with very high VG ratios may slow down cartridge wicking and cause dry hits.
⚠ Charging info: Uwell specifies a charging time of approximately 15 minutes under proper fast charging conditions. Use a quality, undamaged Type-C cable with a suitable 5V USB power source. Do not charge the device in an excessively hot environment or unattended.
