Charging Methods

Direct the solar panel towards the sun to ensure it receives sufficient direct sunlight. Depending on the season and weather, charging may take a long time.
Charging efficiency significantly decreases in shade, cloudy conditions, or under indoor lighting, making it almost impossible to charge.

Charging Through a Window

Even on a clear day, sunlight reflects off windowpanes, so charging through a window will take a long time.
Please try to expose it directly to the sun outdoors as much as possible.

About Optimal Charging

The sun is constantly moving, so make sure your solar panels are oriented correctly and not in the shade.
Solar irradiance increases with sunrise, reaching its maximum around noon. We recommend charging the product in direct sunlight for a few days, ideally between 10 AM and 3 PM on clear days.
