- Connect the cable to your device and the corresponding port on the power bank.
- The power bank will automatically begin charging your device.
4. Operating the Power Bank
4.1 Charging the Power Bank
The power bank offers multiple charging methods:
- Wall Outlet Charging: For the fastest and most efficient charging, connect the power bank to a wall outlet using a compatible USB adapter and the provided Micro Charging Cable or a USB-C cable (not included). This is the recommended primary charging method.
- Solar Charging: The integrated solar panel allows for supplemental charging using sunlight. While effective for maintaining charge or emergency power, solar charging is slower and dependent on sunlight intensity. For best results, place the power bank with the solar panel facing direct sunlight. This method is ideal for outdoor use when a wall outlet is unavailable.
- Hand Crank Charging: In situations without sunlight or electrical outlets, the hand crank provides an emergency power source. Extend the hand crank and rotate it consistently to generate power. This method is intended for emergency use to provide a minimal charge.

The power bank includes a built-in flashlight with 4 LEDs and multiple modes:
- To turn on the flashlight, double-press the power button located on the side of the device.
- Press the power button once to cycle through the different modes (e.g., steady light, flashing, SOS).
- Double-press the power button again to turn off the flashlight.

6. Troubleshooting
If you encounter issues with your power bank, consider the following:
- Device not charging: Ensure the power bank is sufficiently charged. Check all cable connections for proper seating. Try a different cable or output port.
- Power bank not charging: Verify the charging cable and power source are functional. Ensure the power bank is not exposed to extreme temperatures.
- Solar charging is slow: Solar charging is supplementary. Ensure the solar panel is clean and exposed to direct, strong sunlight.
