7w Solar Powered Exhaust Fan Air Extractor 6-inch Panel Ventilator Black

Description

The fan runs when the solar panel is connected, can be used alone by plugging into a computer's USB port. With solar panels plugged in, the way the fan works depends on sunlight. When the sun is strong, the fans work fast. When the sun is not strong enough, the fan may work very low or not work. When the hot air is generated by the sunlight, the fan rotates immediately, dissipating heat in time, and ventilating. Saving the trouble of pulling the wire, safer and more convenient.
