- Unfold the solar panels completely to expose them to direct sunlight.
- For best results, position the panels perpendicular to the sun's rays.
- The solar charging indicator light will illuminate when receiving sufficient sunlight.
- You can also charge your phone simultaneously while the power bank is being charged by sunlight.

4. Maintenance
- Cleaning: Use a soft, dry cloth to wipe the surface of the power bank and solar panels. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the power bank in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Battery Care: To prolong battery life, fully charge the power bank at least once every three months, even if not in regular use.
- Water Resistance: While designed to be rain and dust resistant, avoid submerging the device in water. Ensure ports are dry before charging.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not charging from power bank. | Power bank battery is depleted; cable is faulty; device is incompatible. | Recharge the power bank fully. Try a different USB cable. Ensure your device is compatible with USB charging. |
| Solar charging is very slow or not working. | Insufficient direct sunlight; panels are dirty or obstructed; solar charging is supplementary. | Ensure panels are in direct, strong sunlight and clean. Solar charging is slower than wall charging and best for maintaining charge or emergencies. |
| Flashlight not turning on. | Power button not pressed correctly; power bank battery is too low. | Press and hold the power button for 2-3 seconds. Recharge the power bank. |
| Power bank not charging via Micro USB. | Cable is faulty; wall adapter is insufficient; port is damaged. | Try a different Micro USB cable and wall adapter. Ensure the adapter provides sufficient power (e.g., 5V/2A). |
