Follow the indicator lights on the unit to monitor remaining charge and charging status.

Usage recommendations

Store the power bank in a dry, cool place and avoid exposing it to high temperatures. Use certified cables and chargers to maintain safe charging performance. If the power bank will not be used for extended periods, recharge it partially every few months to preserve battery health. Do not attempt to disassemble the device; follow manufacturer guidance for maintenance and safety.
