Portable Ice Maker
Over at Neiman Marcus they have the perfect ice machine for the back fo the car, the cubicle, or wherever you need some ice without carrying around a refrigerator with you.
It makes 3 different cube sizes, makes 12 cubes in 8 minutes, and holds 2.5 lbs of ice in storage. This beast can push out 33 lbs a day of chilly goodness.
It's basically a 17" cube but doesn't have a cigarette lighter plug-in, so you'll need an inverter to use it in the car.
