4. Setup
4.1 Charging the Power Bank
Before initial use, it is recommended to fully charge the power bank using a wall charger. This ensures the internal battery is at its optimal capacity.
- Via Wall Charger (Recommended for daily charging): Connect the provided USB-C cable to the USB-C port on the power bank and plug the other end into a 5V/2A or higher wall adapter (not included). The LED indicator lights will show the charging progress. A full charge typically takes approximately 10.5 hours.
- Via Solar Panel (Emergency function): Place the power bank in direct sunlight. The solar panel will convert sunlight into electricity to charge the internal battery. The solar charging indicator light (sun icon) will flash when charging. Note that solar charging is significantly slower and is intended for emergency situations due to the instability of sunshine intensity and duration.

6. Maintenance
- Keep the power bank away from extreme temperatures (hot or cold) and direct heat sources.
- Avoid dropping or subjecting the device to strong impacts, despite its durable design.
- Clean the solar panel regularly with a soft, dry cloth to ensure optimal solar charging efficiency.
- Store the power bank in a cool, dry place when not in use.
- For prolonged storage, charge the power bank to at least 50% every three months to maintain battery health.
7. Troubleshooting
- Power bank not charging: Ensure the charging cable is securely connected to both the power bank and the power source. If using solar, ensure the panel is in direct sunlight and the solar indicator is flashing.
- Slow solar charging: Solar charging is an emergency feature and is inherently slower than wall charging. Factors like cloud cover, angle of the sun, and panel cleanliness can affect efficiency. For faster charging, use a wall adapter.
- Device not charging from power bank: Ensure the power bank has sufficient charge. Try a different USB port or charging cable. Verify your device is compatible with USB charging.
- Flashlight not working: Ensure the power bank is turned on and has sufficient charge. Press and hold the power button for 3 seconds to activate the flashlight.
