3. Setup

To ensure optimal performance, follow these steps for setting up your FlexSolar 20W Portable Solar Panel:

1. Unfold the Panel: Gently unfold the solar panel completely to expose all monocrystalline cells.
2. Position for Sunlight: Place the unfolded panel in direct sunlight. Ensure no shadows are cast on the solar cells for maximum efficiency. The panel can be laid flat or hung using the included carabiners on a backpack or tent.
3. Connect Your Device: Locate the USB output ports on the panel. Connect your device (smartphone, tablet, power bank, etc.) using a compatible USB cable to either the USB QC 3.0 port or the PD 15W port.
4. Verify Charging: Your device should indicate that it is charging. The built-in smart chip will automatically detect your device and deliver the appropriate charging speed.

4. Operating Instructions

The FlexSolar 20W Portable Solar Panel is designed for straightforward operation. Here’s how to use it effectively:

1. Single Device Charging: For optimal charging speed, connect a single device to either the USB QC 3.0 port or the PD 15W port. The panel can deliver up to 15W (max) to a single device under sufficient sunlight.
2. Dual Device Charging: If two ports are used simultaneously, the power output will be distributed. One side can provide up to 10W (max). The smart charging technology will adjust the output to suit the connected devices.
3. Sunlight Exposure: Ensure the solar panels are exposed to direct, unobstructed sunlight. Cloudy conditions or indirect light will reduce charging efficiency.
4. No Internal Storage: This solar panel does not have an internal battery to store power. It generates electricity directly from sunlight to charge connected devices.

5. Maintenance

Proper maintenance will extend the lifespan and ensure the efficiency of your FlexSolar 20W Portable Solar Panel:

• Cleaning: Regularly wipe the solar panels with a soft, damp cloth to remove dust, dirt, or debris that may accumulate and reduce efficiency. Avoid abrasive cleaners or harsh chemicals.
• Water Resistance: The panel is IP67 waterproof, meaning it is resistant to sweat, water, and rain. However, avoid submerging the panel in water or exposing the USB ports to excessive moisture when in use. Ensure ports are dry before connecting devices.
• Storage: When not in use, fold the panel and store it in a cool, dry place away from direct sunlight and extreme temperatures.
• Handling: Handle the panel with care to avoid physical damage to the solar cells or the integrated ports.

6. Troubleshooting

If you encounter issues with your FlexSolar 20W Portable Solar Panel, refer to the following common troubleshooting tips:

• Device Not Charging:
  • Ensure the solar panel is in direct, unobstructed sunlight.
  • Check that the USB cable is securely connected to both the panel and your device.
  • Verify that your device is compatible with USB charging.
  • Try a different USB cable or port on the solar panel.
• Slow Charging:
  • Charging speed is highly dependent on sunlight intensity. Ensure maximum direct sunlight exposure.
  • Cloudy weather, shade, or dirty panels will significantly reduce charging speed. Clean the panels if necessary.
  • If charging two devices, the power is split, which may result in slower charging for each.
• Intermittent Charging:
  • Movement or partial shading can cause intermittent charging. Keep the panel stable and in consistent sunlight.
  • Ensure the cable connections are stable and not loose.
