Typically your home refrigerator would be running at between 2 and 4 °Celsius which is optimum for good food preservation. With camping refrigerators, some campers choose a temperature a little higher than that to conserve battery power. With Dometic WAECO CFX3 portable refrigerators you are able to select a temperature to suit your needs in 1°C increments. For freezing, your home deep freezer would operate somewhere between minus 18 and minus 20 °Celsius. For camping applications however, minus 15 ° Celsius would be more than adequate and also conserve battery power.
