How to use

Place the solar panel in direct sunlight on a stable, flat surface or hang it using integrated loops if available. Connect your device or power bank to the panel’s USB output(s) using the appropriate cable. Adjust the panel orientation to maximize sun exposure and avoid shading by trees or equipment. Monitor charging status on the connected device and disconnect when charging is complete or if weather conditions change. For best results, charge during peak daylight hours when sunlight is strongest.

Recommendations

To achieve optimal performance, position the panel at an angle toward the midday sun and keep the surface clean from dust and debris. Use a compatible power bank when charging devices that require stable input or when intermittent sun exposure is expected. Avoid prolonged exposure to extreme weather; store the panel dry and folded when not in use.
