Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Power bank not charging | Cable not connected properly; faulty cable/adapter; power bank fully discharged. | Ensure cables are securely connected. Try a different cable or wall adapter. Allow sufficient time for charging, especially if fully depleted. |
| Device not charging from power bank | Power bank battery low; incorrect cable/port; device not compatible with wireless charging; power bank in standby mode. | Check power bank battery level. Ensure correct cable and port are used. For wireless charging, verify device compatibility and proper placement. Press the power button to activate output if needed. |
| Slow charging speed | Using a non-fast charging port/cable; device not supporting fast charging; multiple devices charging simultaneously. | Ensure you are using a fast-charging compatible port and cable. Some devices may not support 22.5W fast charging. Charging multiple devices can reduce individual charging speeds. |
| Solar charging is slow or not working | Insufficient direct sunlight; solar panel obstructed; solar charging is supplementary. | Place the power bank in direct, unobstructed sunlight. Remember solar charging is for emergency use and trickle charging, not primary power. |
| Flashlight not working | Incorrect operation; power bank battery low. | Press the power switch twice quickly to activate. Ensure the power bank has sufficient charge. |
