Frequently Asked Questions
Does it fit any lithium-ion battery?
Yes, if your battery has a nominal voltage of 3.7V (charging to 4.2V) and a compatible 5.5x2.1mm DC plug. Check the battery specifications before connecting.
Can I leave the charger connected overnight without risk?
Yes, the integrated protection system automatically stops charging when the battery is full, eliminating the risk of overcharge even if it remains connected for several hours.
