FAQ

Q: Is this charger compatible with both original and replacement batteries?

Q: What should I pay attention to during charging?

A:

1. Optimal Environment: Charge in a dry, ventilated area away from heat or direct sunlight.

3. Power Off: Unplug the charger when not in use to extend its lifespan.

Q: Does the warranty cover all types of failure? 

A: Our warranty specifically covers original manufacturing defects. It does not cover malfunctions caused by user error, such as using an incompatible power source, physical drops, or failing to follow the safety guidelines provided in the manual.
