The Igloo ICF40 compressor cool box has an extended temperature range of +20 C to -18 C. This allows you to transport or store frozen products without restrictions. Even in a car or camper, the cool box reaches temperatures below freezing point if it is only connected to the cigarette lighter. You can set the desired temperature via the intuitive display. Here you also activate the 3-stage battery monitor, which prevents the battery of your vehicle from running out.
