Our TOTALFREEZE 55l was purchased for use in our Motorhome on a recent holiday. It was primarily used as a freezer allowing us to make fewer grocery shopping trips, and compensate for the rather meagre freezer capacity in the motorhome’s built in fridge freezer. It maintained a steady temperature of -20 Celsius and we powered it with 240V mains at night and 12V from a solar rechargeable mobile power station during the day. The freezer unit proved to be very efficient and maintained -20 Celsius by intermittently drawing 25-30 watts/hr of electrical energy. Attached to a 300watt/hr capacity mobile power station we were able to run the unit continuously for 17 hours without depleting all the charge. When the condenser runs there is some background fan noise but as we stored the unit in the motorhome garage this was not intrusive. The fan noise is a perhaps a little bit louder than the hum many domestic fridges emit but is certainly tolerable. There was a small amount of condensation on the outer plastic shell of the freezer, but again this was minimal and did not leave moisture on the floor of the motorhome garage. The Bluetooth and app worked well allowing us to remotely monitor the performance of the fridge/freezer unit without having to exit the main living area in the motorhome.All in all I’m very impressed by the build quality, functionality and efficiency of our TOTALFREEZE unit, and it will undoubtedly get more use as a fridge on longer car trips and as a backup/extra capacity freezer at home. The utility of this freezer unit with 240v mains power, 12V mobile power stations, 12V leisure batteries and 12V vehicle batteries makes it an almost essential bit of kit for holidays and for longer excursions.
