Q: How long does the Uwell Caliburn AK2 battery last on a full charge?

The 520mAh battery in the AK2 is designed for MTL vaping and lasts approximately a full day under moderate use. Battery life depends on your vaping frequency and session length. For heavy users, the device might require a quick recharge by the evening. The LED battery indicator helps monitor charge levels: Green: Full charge (60-100%) Blue: Medium charge (30-60%) Red: Low charge (below 30%).

Q: What e-liquids work best with the Uwell Caliburn AK2?

The AK2 is optimized for nicotine salts and high-PG e-liquids (50/50 VG/PG). While it can handle some higher VG e-liquids (e.g., 60VG), overly thick liquids (70VG+) may reduce coil life or cause dry hits. Stick to nicotine strengths between 10-50mg for salts or 6-12mg for freebase nicotine to get the best throat hit and flavor.

Q: Can I adjust the airflow on the Uwell Caliburn AK2?

No, the AK2 features a fixed airflow system that is finely tuned for MTL vaping. It provides a tight draw similar to traditional cigarettes, making it ideal for those transitioning from smoking.
