3. Setup
- Unfold the Solar Panel: Carefully unfold the solar panel completely to expose all solar cells.
- Positioning: Place the solar panel in direct sunlight. For optimal performance, ensure the panel is angled directly towards the sun. Avoid shaded areas, as even partial shading can significantly reduce charging efficiency.
- Securing the Panel: Use the included carabiners to attach the solar panel to a backpack, tent, or other suitable object to maintain its position and angle towards the sun, especially during outdoor activities like hiking or camping.

4. Operating Instructions
- Connect Your Device: Once the solar panel is exposed to sufficient sunlight, connect your electronic device (smartphone, tablet, power bank, etc.) to either the USB-A or USB-C output port using a compatible charging cable.
- Automatic Charging: The solar charger will automatically detect your device and begin charging. No power button is required. A small LED indicator on the port box may illuminate to confirm power output.
- Dual Device Charging: You can charge two devices simultaneously. The total power output will be intelligently distributed between the two ports. For maximum charging speed for a single device, connect only one device.
- Monitoring Charging: Monitor your device's charging indicator to confirm it is receiving power. Charging efficiency may vary based on sunlight intensity and angle.
- Disconnecting: Disconnect your device once it is fully charged or when solar conditions are no longer optimal.

5. Maintenance
- Cleaning: Wipe the solar panels with a soft, damp cloth to remove dust or dirt. Do not use harsh chemicals or abrasive materials. Ensure the panel is dry before folding or storing.
- Storage: When not in use, fold the solar panel and store it in a cool, dry place away from direct sunlight and extreme temperatures.
- Port Protection: Always ensure the charging port box is protected from water, especially during rain or in wet conditions, as it is not waterproof.
- Inspection: Periodically inspect the panel and cables for any signs of damage. Do not use if damaged.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not charging. | Insufficient sunlight. Incorrect panel angle. Damaged cable or device. Port box is wet. | Move panel to direct sunlight. Adjust panel angle towards the sun. Try a different cable or device. Ensure port box is dry and protected. |
| Slow charging speed. | Partial shading on the panel. Low sunlight intensity (cloudy day). Charging multiple devices. | Ensure no shadows fall on the panel. Optimize panel position for maximum light. Charge one device at a time for faster speed. |
| LED indicator not lit. | No power output from the panel. Insufficient sunlight. | Ensure panel is in direct sunlight. Check for any obstructions. |
