• Keep the panel away from fire or extreme heat sources.
• Ensure children do not play with the device.
• Use only compatible charging cables and devices.

4. Setup

1. Unfold the Panel: Carefully unfold the FlexSolar panel completely to expose all solar cells.
2. Position for Sunlight: Place the unfolded panel in direct sunlight. For optimal performance, angle the panel directly towards the sun. Avoid shaded areas, as even partial shading can significantly reduce efficiency.
3. Secure the Panel: Use the integrated carabiner holes and included carabiners to secure the panel to a backpack, tent, or other stable surface, ensuring it remains facing the sun.
4. Connect Your Device: Locate the USB-A and USB-C output ports on the control box. Connect your device using a compatible USB cable.

5. Operating Instructions

The FlexSolar 20W Portable Solar Panel converts sunlight directly into electricity. It does not store power internally, so devices must be connected while the panel is exposed to sunlight.

• Charging Devices: Once the panel is set up in direct sunlight, connect your smartphone, power bank, GPS, or other compatible USB device to either the USB-A (5V/3A Max) or USB-C (5V/3A Max) port.
• Charging Indicator: A red LED indicator on the control box will illuminate when the panel is receiving sufficient sunlight and generating power.
• Optimal Performance: The panel achieves up to 24% conversion efficiency in ideal conditions (clear, direct sunlight). Charging speed will vary based on sun intensity, cloud cover, and device power requirements.
• Simultaneous Charging: You can charge two devices simultaneously, but the total output will be shared between them.

6. Maintenance

• Cleaning: Regularly wipe the solar panel surface with a soft, damp cloth to remove dust, dirt, or debris. A clean surface ensures maximum sunlight absorption. Do not use harsh chemicals or abrasive materials.
• Storage: When not in use, fold the solar panel and store it in a cool, dry place away from direct sunlight and extreme temperatures.
• Inspection: Periodically inspect the panel and cables for any signs of damage.

7. Troubleshooting

• Device not charging:
  • Ensure the panel is in direct, unobstructed sunlight.
  • Check all cable connections to ensure they are secure.
  • Verify that the red LED indicator on the control box is illuminated.
  • Test with a different USB cable or device to rule out cable/device issues.
• Slow charging:
  • Adjust the panel's angle to face the sun directly.
  • Clear any dust or debris from the solar panel surface.
  • Cloudy weather or low sun angle will naturally reduce charging speed.
  • Ensure your device is not drawing more power than the panel can supply (e.g., charging a large tablet while using it intensively).
