This product is a solar nightlight. Its luminous method is inspired by the moon. The energy is supplemented by sunlight and the luminous range is adjusted by rotation. The brightness adjustment method is to rotate the roller in the middle, and the fixed method is the suction cup at the rear of the lamp body, which is mainly adsorbed on the glass or other flat materials. The charging method can be realized through the solar panel at the back. There is also a traditional charging interface.
