The concept behind Powerkeep's mini refrigerator is to save energy by minimizing the outflow of cool air. This creative refrigerators save space for the car owner but also saves energy not used to unnecessarily refrigerate extra area.

The cooler comes with belt holder so it's easier to carry, and the whole case features a rugged design so it can survive numerous trips and parties unscathed. The inside lid even contains a small light, so you can find what you need in the dark. It may look like a simple concept, but getting the right balance of size and power management required some thorough research and testing. The cooler incorporates some advanced circuitry to distribute the power to the refrigeration system, all while taking up a relatively small amount of space.
