3. Setup Instructions
Setting up your MARBERO 30W Portable Solar Panel is straightforward. Follow these steps to begin charging your devices:
- Unfold the Panel: Lay the solar panel completely flat in an area with direct sunlight.
- Position for Optimal Sunlight: Angle the panel directly towards the sun. For best results, an angle of 45 to 65 degrees relative to the sun is recommended. Avoid shaded areas, as even partial shading can significantly reduce efficiency.
- Connect Your Device:
- For USB or USB-C devices, plug your charging cable directly into the corresponding port on the panel's control module.
- For DC devices or portable power stations, select the appropriate 10-in-1 DC adapter. Connect one end of the DC cable to the panel's DC output port and the other end to your device.
- Verify Charging: Most devices will indicate when they are receiving a charge. The panel's control module may also have an indicator light.

4. Operating Instructions
Once set up, the MARBERO 30W Portable Solar Panel operates automatically to charge your devices. Here are some operational considerations:
- Automatic Device Recognition: The built-in smart chip intelligently recognizes your connected device to deliver the optimal charging current, maximizing charging speed while protecting against overcharging and overloading.
- Performance in Various Conditions:
- Under full sunlight and optimal angle (45 to 65 degrees), the panel generates 25W-30W.
- On cloudy days, it can still provide 15W-20W, ensuring dependable power.
- Direct Power Generation: This portable solar charger generates electricity directly from sunlight and does not store power internally. It must be connected to a device or power bank to transfer energy.
- Multiple Device Charging: Utilize the various USB, QC3.0, and USB-C ports to charge multiple compatible devices simultaneously.

5. Maintenance
Proper maintenance will extend the lifespan and ensure the continued efficiency of your solar panel:
- Cleaning: Regularly wipe the solar panel surface with a soft, damp cloth to remove dust, dirt, or debris. Avoid using abrasive cleaners or harsh chemicals, as these can damage the panel's surface.
- Storage: When not in use, fold the solar panel and store it in a dry, cool place away from direct sunlight and extreme temperatures. The integrated pocket can be used to store cables and adapters.
- Handling: Handle the panel with care. Avoid dropping it or placing heavy objects on it. Do not bend the panel excessively or apply undue pressure to the solar cells.
- Port Protection: Ensure that the USB and DC ports are kept clean and dry. While the panel is IP65 waterproof, prolonged exposure of the ports to moisture should be avoided.

6. Troubleshooting
If you encounter issues with your MARBERO 30W Portable Solar Panel, consider the following troubleshooting steps:
- Issue: Device not charging or charging slowly.
- Solution: Ensure the solar panel is unfolded completely and positioned directly facing the sun. Adjust the angle for optimal sunlight exposure (45-65 degrees). Check all cable connections to ensure they are secure and properly inserted into the correct ports. Clean the solar panel surface if it's dirty or dusty. Note that clouds, angle toward sunlight, operating temperature, and sunlight intensity will affect the real output.
- Issue: USB ports not functioning.
- Solution: Inspect the USB ports for any debris or signs of damage, such as rust. Ensure charging cables are fully inserted and are not faulty. Try a different USB port or cable if available.
- Issue: Panel not producing power in seemingly good conditions.
- Solution: Verify that no part of the panel is shaded, even partially. Ensure the panel is not placed behind a window or windscreen, as this can significantly reduce efficiency. Confirm that the connected device is compatible and not already fully charged.
If these steps do not resolve the issue, please refer to the Warranty and Support section for further assistance.
