Flower like USB Fan for laptop. Simply Plug into USB Port. Fully Adjustable fan. Optional 3 x AA Battery Holder to use it anywhere without Laptop or PC. This USB gadget will help you to keep cool during the hot summer days. Its blades are made of rubber. They seem quite tough, and they’re soft enough that even a baby won’t hurt its hand if it grabs the fan while it’s spinning. There’s a little on/off switch on the side, so you don’t have to unplug the fan to turn it off.
