Safety Precautions

To ensure safe operation and prevent damage, please read and follow these precautions.

1. Electrical Safety: Do not expose the charger or connected devices to rain, snow, or submerged in water. While water-resistant, it is not waterproof for prolonged exposure.
2. Heat & Sunlight: Avoid leaving the charger in direct, intense sunlight when not in use for extended periods. Do not place on hot surfaces.
3. Device Compatibility: Only charge devices with a standard 5V USB input. Do not attempt to charge non-USB devices or modify the output.
4. Cable Inspection: Regularly inspect cables for damage. Do not use if cables are frayed or exposed.
5. Storage: Store in a cool, dry place away from direct sunlight when not in use for long periods.

WARNING! Never look directly at the sun or point the reflective surface of the panel towards eyes. Do not disassemble the unit.

Controls and Indicators

The charger has a simple interface for operation and status indication.

Physical Components:

1. Solar Panel Array: The main surface with multiple solar cells.
2. USB Output Ports: Two standard USB-A ports located on the side panel.
3. LED Power Indicator: A small blue LED next to the USB ports.
4. Integrated Cable: Stored in a side pocket; tips can be swapped.
5. Kickstands: Four fabric loops with plastic stiffeners to angle the panel.
6. Carabiner Clip: Metal clip for attaching to a backpack or gear.

Indicator Status:

• LED Off: No or insufficient sunlight. Reposition the panel.
• LED Solid Blue: Panel is receiving adequate sunlight and outputting power.
• LED Flashing Blue: Potential short-circuit or overload. Disconnect devices and restart.

Initial Setup & Charging

Follow these steps to begin charging your devices.

1. Unfold: Fully unfold the solar panel on a flat surface.
2. Position for Sun: Place the panel in direct sunlight. Use the kickstands to tilt it towards the sun for best results (optimal angle is roughly equal to your latitude).
3. Connect Your Device:
   • Use the integrated cable or your own USB cable.
   • Plug the USB-A end into one of the charger's output ports.
   • Plug the other end (USB-C, Micro-USB, or Lightning) into your device.
4. Check Indicator: The blue LED should light up, indicating power generation.
5. Device Charging: Your device should show it is charging. Note: Charging speed depends on sunlight intensity.
6. Multiple Devices: You can charge two devices simultaneously. Total output is shared (max 4.2A).
7. Storage: After use, disconnect devices, fold the panel, and store it in the provided pouch.

Tip: For fastest charging, ensure the panel surface is clean and perpendicular to the sun's rays. Avoid shadows on the panel.

Optimal Usage Tips

Maximize the efficiency and lifespan of your solar charger.

1. Sunlight is Key: Output is directly proportional to sunlight intensity. Full, direct sun yields maximum power. Cloudy days will significantly reduce output.
2. Angle Adjustment: Adjust the panel every 1-2 hours to follow the sun for consistent power.
3. Cooler is Better: Solar panels are more efficient in cooler temperatures. If possible, allow for airflow behind the panel to prevent overheating.
4. Charge Power Banks First: For indirect charging, use the solar panel to charge a power bank during the day, then use the power bank to charge devices at night.
5. Device Compatibility: The smart IC will match the device's input needs. It supports standard 5V charging protocols (BC1.2, Apple, Samsung etc.).
6. Partial Shade: Even a small shadow on one cell can reduce the output of the entire panel. Keep the entire surface in sunlight.

Care & Maintenance

Proper care ensures long-term performance.

1. Cleaning: Wipe the solar panel surface gently with a soft, dry cloth. For stubborn dirt, use a cloth slightly dampened with water. Do not use chemicals, abrasives, or solvents.
2. Storage: Always fold and store in the dry pouch provided. Store in a cool, dry place.
3. Inspection: Periodically check for any physical damage to the panel, fabric, or cables.
4. Water Resistance: While splash-resistant (IPX4), do not submerge or expose to heavy rain for prolonged periods. Dry thoroughly if it gets wet.

CAUTION! Do not attempt to repair or open the sealed panel assembly. This will void the warranty and may cause injury.
