This is a fantastic electric cooler based on the free piston Stirling cycle that will maintain freezing temps even in a hot car. The power consumption is amazing, 24 watts. It’s quiet, light weight, works great. Much more practical than the portable compressor or propane based freezers. I’ve had two in continuous use for two years now and they are wonderful. I think this product has not taken off like it should because of confusion with the cheaper, power hogging thermo-electric Peltier-type coolers.
