4. Operating Instructions
4.1 Charging the Power Bank
Your power bank offers two methods for recharging:
USB Charging (Primary Method):
For fastest and most efficient charging, use a wall adapter. Connect the power bank to a USB wall charger using its Micro USB or Type-C input port. The digital power indicator will show the charging status.
Solar Charging (Emergency Backup):

Figure 4.1: The power bank positioned to receive direct sunlight for solar charging.
The integrated solar panel is designed for emergency charging and maintaining battery life, not as a primary charging method due to its slower conversion rate. Place the power bank in direct sunlight. The solar charging indicator will light up when charging via solar power. For optimal solar charging, ensure the solar panel is clean and unobstructed.
4.2 Charging Your Devices
The power bank supports charging multiple devices simultaneously through its various outputs:
Using Built-in Cables:

Pull out the appropriate built-in cable (USB, Mini USB, Lightning, or Type-C) and connect it to your device. The power bank will automatically begin charging.
Using Wireless Charging:

Place your Qi-compatible device on the wireless charging area of the power bank. Ensure the device is centered for optimal charging. The power bank will automatically detect and begin wireless charging.
Using USB Output Port:
Connect your device's charging cable to the standard USB-A output port on the power bank. The power bank will automatically begin charging your device.

5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the power bank. Do not use harsh chemicals or abrasive materials.
- Storage: Store the power bank in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, charge the power bank to about 50-75% capacity every 3 months to preserve battery life.
- Water Resistance: The power bank has an IP65 waterproof rating, meaning it is protected against low-pressure water jets from any direction and dust ingress. It is suitable for damp environments and light rain. Do not submerge the power bank in water.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Power bank not charging devices or charging slowly. | Low battery on power bank; cable connection issue; device not compatible; power bank capacity lower than expected. | Ensure power bank is fully charged. Check all cable connections. Verify device compatibility. Note that the actual usable capacity may be slightly less than advertised due to energy conversion loss. |
| Solar charging is very slow or not working. | Insufficient direct sunlight; solar panel obstructed or dirty; solar charging is designed as an emergency feature. | Place the power bank in direct, strong sunlight. Clean the solar panel. Understand that solar charging is significantly slower than USB charging and is intended for emergency top-ups, not primary charging. |
| Power bank overheating during use/charging. | Overload; poor ventilation; direct sunlight exposure during charging. | Disconnect devices and allow power bank to cool down. Ensure adequate ventilation. Avoid charging in direct sunlight or enclosed spaces. If overheating persists, discontinue use. |
| LED flashlight not working. | Low battery; incorrect operation. | Charge the power bank. Double-press the POWER button to activate/deactivate the flashlight. Single-press to cycle modes. |
