This manual provides essential information on how to set up, operate, maintain, and troubleshoot your FlexSolar 10W Portable Solar Charger to ensure optimal performance and longevity.

2. Safety Guidelines

• Do not attempt to disassemble, repair, or modify the solar charger. This may void the warranty and pose safety risks.
• Avoid exposing the junction box (USB port area) to water, as it is not waterproof, despite the panel's IP67 rating.
• Keep the solar panel away from fire, extreme heat, and corrosive materials.
• Ensure the solar panel is placed on a stable surface or securely attached to prevent it from falling or being damaged.
• Do not puncture or apply excessive pressure to the solar panels.
• Supervise children when they are near the device.

3. Package Contents

Please verify that all items are present in the package:

• 1 x FlexSolar 10W Portable Solar Charger
• 2 x Carabiners

4. Setup

1. Unfold the Solar Panel: Carefully unfold the FlexSolar 10W Portable Solar Charger to its full extent.
2. Position for Sunlight: Place the solar panel in a location where it receives direct and unobstructed sunlight. For optimal performance, orient the panel perpendicular to the sun's rays. Avoid shaded areas or placing it behind glass, as this significantly reduces charging efficiency.
3. Secure the Panel: Use the included carabiners to attach the solar panel to a backpack, tent, or other suitable structure. This ensures stability and optimal sun exposure, especially during outdoor activities.

5. Operating Instructions

1. Connect Your Device: Plug your USB-compatible device (e.g., smartphone, tablet, small power bank, USB fan, flashlight, smartwatch) into the built-in USB-A port of the solar charger using an appropriate charging cable.
2. Monitor Charging: The integrated LED indicators will provide real-time status updates, confirming that charging is in progress. The advanced IC chip intelligently identifies connected devices to optimize charging efficiency.
3. Optimal Charging Conditions: For best results, ensure the solar panel is exposed to direct sunlight. The maximum output is 10W under ideal conditions. Charging speed will vary depending on sunlight intensity, device capacity, and cable quality.

Important Note: The FlexSolar 10W Portable Solar Charger does not have internal energy storage capabilities. It charges devices directly from sunlight. Continuous sunlight is required for uninterrupted charging.

6. Care and Maintenance

• Cleaning: Wipe the solar panels with a soft, damp cloth to remove dust or dirt. Avoid using harsh chemicals or abrasive materials that could scratch the ETFE film. Ensure the panel is dry before folding or storing.
• Storage: When not in use, fold the solar charger and store it in a cool, dry place away from direct sunlight and extreme temperatures.
• Durability: The solar panel features weather-resistant ETFE film lamination and high-efficiency monocrystalline A+ solar cells, providing IP67-rated durability against dust and water splashes. However, the junction box (USB port area) is not waterproof and should be protected from moisture.

7. Troubleshooting

• Device Not Charging:
  • Ensure the solar panel is in direct sunlight and not obstructed by shadows.
  • Verify that the charging cable is securely connected to both the solar panel's USB-A port and your device.
  • Avoid charging through glass surfaces (e.g., windows), as this significantly reduces the panel's efficiency.
  • Check if your device requires more power than the 10W maximum output of the charger.
  • If the sun is intermittent (e.g., cloudy conditions), the charging process may pause and resume, which is normal for direct solar charging.
• Slow Charging Speed:
  • Ensure the panel is optimally angled towards the sun.
  • Clean the panel surface if it is dirty.
  • Charging speed is directly dependent on sunlight intensity. Stronger, direct sunlight yields faster charging.
  • The charging speed also varies by device capacity and the quality of the charging cable used.
