USB Fridge
Keep your cool at your desk at all times. Get through the hot summer days with a steady chilled drink. The USB Fridge simply plugs into your computer and can fit a standard sized soda can. Your beverage will no longer warm up while you are stressing over spreadsheets.
Mini Fridge for a 6 pack
If a single can fridge is not enough for you, perhaps a 6 pack will do the trick. This one is the 6 can Koolatron mini fridge. However, this one is not USB powered, you would have to actually plug it into the wall, but it is more powerful.
