A USB fan is a small fan that can plug into any USB port. These are usually a personal fan designed with convenience and portability in mind. USB fans sometimes come with a clip, which allows you to position them easily on a computer screen, in a tent, or on a stroller. A USB fan may come with rechargeable batteries. Expect the diameter on a USB-powered fan to be about 3” to 9”. While USB fans often have more than one speed setting, they do not push as much air as their larger AC-powered counterparts. Cable lengths on the USB cords are not usually very long.
