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
The colors of Powerkeep's '12 litres extremely cold car
refrigerator' are white and black, the liner material is aluminium
alloy, and the housing material is plastic. The liner size is
L330*W200*H200(MM), the whole product size is L515*W280*H350(MM).
The user could adjust and control the liner temperature through the
nixie tube and mini switch push button. Finally, the temperature
could decrease from 40°C to -20°C within 1 hour, the temperature
range is from -20°C to 60°C.
