راهاندازی و شارژ پاور بانک
Before using the power bank to charge other devices, ensure it is fully charged.
- Select an Input Port: The power bank features three input ports: Micro USB, Lightning, and USB Type-C. Choose the appropriate cable for your power adapter.
- اتصال به منبع تغذیه: Plug the charging cable into one of the input ports on the power bank and connect the other end to a compatible power adapter.
- Fast Charging Input: For the fastest recharging (approximately 4.5 hours for a full charge), use a 65W power adapter and a compatible USB Type-C cable. Using an 18W adapter will take approximately 10.1 hours for a full charge.
- وضعیت شارژ مانیتور: The digital display will show the current, voltage, fast charging status, and battery level during the charging process.
مهم: To achieve 65W max wattage for recharging, both the Type-C cable and the power adapter must support 65W fast charging.
