Installation and usage advice

To achieve the best performance, place the panel in direct sunlight and position it to maximise exposure. Avoid shaded areas, even partially shaded ones, as they can reduce overall efficiency. It is recommended to place the panel on a stable, dry and well-ventilated surface during use.

For charging sensitive or low-capacity devices, using an intermediate power bank may be useful depending on sunlight conditions. Actual performance may vary depending on the season, light intensity, the angle of the sun and ambient temperature. This product is intended for charging devices compatible with its electrical output and does not replace a fixed solar installation.

• Fully unfold all three sections before use
• Position the panel facing the sun for better efficiency
• Keep the connection ports protected from moisture
• Check device compatibility before connecting
• Store the panel after use in a dry place
