This is the simplest kind of portable fan, but it takes manpower to shake the fan, and human activities cause more heat, so the actual use effect is not good. With the continuous development of science and technology, people have invented electric fans. Fans refer to appliances that are used to generate wind and cool down on hot days. Electric fans are devices that use electricity to generate airflow. When the fan inside is powered on, it rotates and turns into natural wind to achieve a cool effect. In order to make electric fans, a comfortable cooling tool, serve humans anytime and anywhere, many electrical appliance manufacturers have installed batteries on traditional fans. The places where they are used are not restricted by the city power grid lines, and the batteries they carry are used to provide power.
