【Cool and Refreshing】This solar fan expels warm air and blows in cool air, effectively lowering indoor temperatures and keeping the air fresh.

Ideal for small chicken coops, greenhouses, barns, animal pens, and window ventilation in hot weather. 【Green Energy, Equipped with USB Interface】This solar fan efficiently converts sunlight into electricity, has a long lifespan, and is a green energy source. The solar panel can also be used as a backup power source to charge your devices.

Simply connect the solar panel interface to the fan and place it in sunlight. The fan runs fast in bright sunlight; when the sunlight weakens, the fan speed will decrease or stop. You only need to keep the solar panel clean. 【Superior Quality】The surface coating of the solar panel prevents short circuits or rain damage, making it suitable for outdoor use. This solar fan has no built-in battery and only operates during the day.
