This portable clip on fan is super handy and can be clamped anywhere you like to maximize your comfort as long as there is a USB port nearby. Perfect to use in your car or office. Power it with your computer and enjoy cool air in an otherwise stuffy office or improve air circulation inside your truck cab or other vehicle by clipping it to a visor or dash and plugging in the USB cord to a port. It can be adjusted 180 degrees to be aimed where you want the breeze to flow. The super portable and compact size of this mini fan makes it one of the best ways to subtly control room temperature without compromising the comfort level of others nearby. Enjoy your own personal breeze. This is great idea for a college student in dormitory housing that has no AC or who has to share a room with someone with a different idea about comfortable room temperature. This small USB-powered fan can also help make a camping trip or road trip more enjoyable and does not take up a lot of space when packing. Feel a summer breeze whenever you need one.
