5. Operating Instructions
5.1 Charging the Power Bank
The power bank can be charged via wall outlet or solar panel.
- Wall Charging: For fastest charging, use a compatible wall adapter and connect the power bank via its built-in USB-A input cable, or a USB-C/Micro-USB cable to the corresponding input port.
- Solar Charging: Place the power bank under direct sunlight. The solar panel will convert sunlight into electricity to charge the internal battery. Solar charging is a supplementary feature and is slower than wall charging; it is ideal for maintaining charge or for emergency situations when no power outlet is available. A green LED will indicate active solar charging.
5.2 Charging External Devices
The power bank supports charging multiple devices simultaneously through various methods.
