Creative and clever refrigerator that keeps its contents cold using a compact refrigeration system. Even with the semiconductor refrigeration system, this still leaves an interior volume of 12L, that entire space can be completely filled with cold food and drinks. According to the calculation, the cooler can hold a steady 5.5° C for over 24 hours, depending on how often the lid is opened, but can also go as low as -10° C if needed.

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.
