Actually I don't think if you find this gadget is useful or not, but it's a cool and eye catching gadget though.

it's actually a small chiller that you can plugged into USB port on your computer / laptop to power it up and it's used to keep your drinks chilled and cold as you're working with your computer for hours. It only takes seconds for this USB Chiller to make the coldplate chills to 45 degrees fahrenheit. So, do you think you need this kind of stuff ?
