The Handycooler might look like nothing more than a high-tech fan, but it actually harnesses the power of evaporative cooling to keep you comfortable. Inside the unit there’s a sponge you simply dampen with a few ounces of water, and the air that’s drawn over that damp sponge by a fan is cooled by as much as 25 degrees Fahrenheit! Refreshing!
On a set of 4xAA batteries the Handycooler will run for about 5 hours, but it can also be plugged into a power outlet or a USB port for use at your desk. $39.99
