I originally ordered one of these because I wanted one that I could just run as a freezer as I already had a 3 way fridge. But I was so impressed with the performance that I decided to buy a second, to run as a fridge, and sell the 3 way. For my first trail I used mains to get the temperature down to -16 then switched over to the eco setting and connected it to 180Ah truck battery, it ran all day long until I finally switched it off before going to bed. The 3 way will only last for 6 hours on the same battery. Used as a fridge it is deep enough to store bottles of drink and spacious enough for all my needs.
Absolutely ideal for a camper van or a boat, but it's efficient and compact enough to fit in a car.
