5. Charging the Power Bank
5.1. Charging via Cable (Recommended for Fast Charging)
For the fastest and most efficient charging of your power bank, use the included USB-C to USB-C cable with a compatible wall adapter.
- Connect the USB-C cable to the power bank's USB-C input port.

5.2. Charging via Solar Panel
The integrated ETFE solar panel provides an emergency charging option and can extend the battery life when outdoors. Solar charging is slower than cable charging and is highly dependent on direct sunlight intensity.
- Place the power bank in direct sunlight with the solar panel facing upwards.
- Ensure there are no obstructions blocking the solar panel.
- A dedicated solar charging indicator (if present) or the main battery indicators will show activity when solar charging is active.
- For optimal solar charging, avoid placing the device behind glass or in shaded areas.

7. Features and Functions
7.1. ETFE Solar Panel
The 1.5W ETFE (Ethylene Tetrafluoroethylene) solar panel offers enhanced durability and efficiency compared to traditional solar panels. ETFE material provides superior light transmittance, better resistance to high temperatures, and is more resistant to corrosion and dirt buildup, ensuring a longer lifespan and more consistent solar charging performance.
7.2. IP54 Water and Dust Resistance
With an IP54 rating, the Power Bank Solar is protected against dust ingress that could harm the equipment and against splashing water from any direction. This makes it suitable for outdoor use in various weather conditions, though it is not designed for submersion in water.
7.3. Power Delivery (PD) and Quick Charge (QC)
The power bank supports modern fast-charging standards:
- USB-C Power Delivery 20W: Delivers up to 20W of power through the USB-C port, ideal for rapidly charging compatible smartphones, tablets, and other USB-C devices.
- USB 18W QC: Provides up to 18W of power through the USB-A port, compatible with devices supporting Qualcomm Quick Charge technology for faster charging.
8. Maintenance
- Cleaning: Use a soft, dry cloth to clean the power bank. 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 when not in use for extended periods.
- Battery Care: To maintain battery health, fully charge and discharge the power bank at least once every three months if it's not used regularly.
- Port Protection: Ensure the port cover is securely closed when not in use to maintain IP54 water and dust resistance.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Power bank not charging | Cable or adapter issue; power bank fully charged; faulty port. | Try a different cable or wall adapter. Ensure the power bank is not already full. Check for debris in ports. |
| Device not charging from power bank | Power bank low on charge; incorrect cable; device not compatible; faulty port. | Recharge the power bank. Use the correct charging cable for your device. Ensure device is compatible with USB-C PD or USB QC. Try a different port. |
| Solar charging is slow or not working | Insufficient direct sunlight; solar panel obstructed or dirty; cloudy weather. | Place the power bank in direct, unobstructed sunlight. Clean the solar panel. Note that solar charging is supplementary and slower than wall charging. |
| Power bank gets warm during use | Normal operation during charging/discharging; excessive load. | Slight warmth is normal. If it becomes excessively hot, disconnect devices and allow it to cool down. Avoid charging in direct sunlight or enclosed spaces. |
