How long does the Engel 12-Volt Refrigerator Freezer stay frozen when unplugged?
Engel 12-Volt Refrigerator Freezers are extremely well insulated and will provide many hours of cool protection, even when switched off. How many hours will depend on many variables like the out side (ambient) temperature, weight and type of frozen food, wind speed, sunlight, starting temperature etc. Essentially, the Engel’s ability to keep food frozen, and its insulation properties, are similar to a very good quality cooler box when unplugged. Try to keep your Engel 12-Volt Refrigerator Freezers in the shade. Instead of leaving it in a vehicle overnight, use an AC adapter which converts standard 110 Volt AC power to 12-Volts DC and plug the cooler into main power when not driving.
