3. Setup and Initial Charging
Before first use, it is recommended to fully charge the power bank via a USB adapter.
3.1 Charging the Power Bank via USB
- Connect the provided USB charging cable to the Micro USB input port on the power bank.
- Plug the other end of the cable into a 5V/2.1A USB wall adapter or a computer USB port.
- The LED indicators will illuminate to show the charging status. A full charge typically takes 4-5 hours.
- Once all LED indicators are solid, the power bank is fully charged.
3.2 Solar Charging (Emergency Use)
The solar panel is designed for emergency charging and maintaining the battery level, not as a primary charging method. Its maximum charging speed is 5V*0.2A, which is significantly slower than USB charging.
- Place the solar panel directly under strong sunlight.
- The solar charging indicator light will turn on, indicating that solar charging is active.
- For optimal solar charging, ensure the panel is clean and unobstructed.
Important: Always fully charge the power bank via USB before any outdoor trip or extended use.
