USB is very versatile and can be used for anything from transferring data to powering a laptop light. The next thing I found the usb can do is make your beverage cold-The USB Beverage Chiller.
With the USB Beverage Chiller at your side, you can keep your Coke chilled and stay at your computer longer.It looks like a big iPod with a blue wheel and the wheel is the cold plate that fits on can, bottle or glass. It is easy to use, just plug it in to a USB port, and it immediately starts operating, and the cold plate quickly feels cold to the touch. You can then simply place anything on the cold plate and allow it variously to cool down or to stay cool. The cold plate will chill down to 45 degrees Fahreneheit, which is the perfect temperature for keeping your beverage cool.
