Review on Clip On Fan for Baby Stroller: Portable and Rechargeable Mini USB Table Fan for Travel, Camping, and Outdoor Use by Mark Lodge

This fan is small enough to throw in your bag when you go somewhere or just use it around the house. I mostly use it when I'm working on my computer because it easily attaches to the side. You can change the angle and speed, and run it on either battery or mains power. Since I mostly use it with my computer, I just leave it plugged directly into the USB port. It's powerful enough to keep me cool without having to lug around a large fan.
