Small but effective cooler box for temporary storage of food and beverages that need to be kept either hot or cold. Cools to approx. 20 degrees below the ambient temperature and retains heat up to max. 65 degrees with the built-in thermostat. An LED indicator on the side displays the mode, either cold or hot. Volume 4 litres, suitable for six 330ml cans. Two power supplies (230 V AC or 12 V DC) means it can be used at home or in a car, on a boat or on camping trips.
