Setup and Initial Charging
Before first use, it is recommended to fully charge the power bank via a wall outlet.
Charging the Power Bank
- Via Wall Outlet (Recommended):
Connect the power bank to a 5V/3.1A (or higher) USB wall adapter using a USB-C cable. The LED indicators will light up, showing the charging progress. All four LEDs will be solid when fully charged.
- Via Solar Panel (Emergency/Supplementary):
Place the power bank in direct sunlight. The solar charging indicator light(s) will illuminate, indicating that solar charging is active. Solar charging is significantly slower than wall charging and is primarily for emergency power replenishment.

Maintenance
- Cleaning: Wipe the power bank with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the power bank in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, charge the power bank to about 50-75% every 3 months to preserve battery life.
- Water Resistance: While water-resistant, avoid prolonged submersion or exposure to heavy rain. Ensure the USB cover is securely closed when near water.
- Avoid Drops: Although shockproof, repeated severe drops can damage internal components.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Power bank not charging | Cable issue, adapter issue, power bank fully charged, or solar charging insufficient. | Try a different charging cable and wall adapter. Ensure the adapter meets the required voltage/current. If using solar, ensure direct sunlight and allow sufficient time. |
| Device not charging from power bank | Power bank low on battery, cable issue, device not compatible, or power bank not activated. | Check power bank battery level. Try a different charging cable. Ensure your device is compatible with USB charging. Press the power button to activate output if necessary. |
| Slow charging | Using a low-power adapter/cable, or device's charging input limit. | Use a 5V/3.1A or higher wall adapter and a high-quality cable. Note that some devices may have slower charging speeds due to their internal design. Solar charging is inherently slow. |
| Flashlight not working | Power bank low on battery, or incorrect button press. | Charge the power bank. Press and hold the Power/Flashlight Button for 3 seconds to activate. |
