The QOOL Box Cooler Needs No Ice

Utilizing vacuum insulation—similar to a double-walled thermos—the QOOL Box cooler requires no power source or ice yet can keep contents cool, even frozen to -15ºC for up to 10 days. A unique Phase Changing Material replaces ice as the source of cooling which emits a steady stream of cooling energy to keep perishables and cold drinks at exactly the temp you want them.
