(If you can do this don't forget to include average temperatures)
We tried a truck stop car fridge, but found it both ineffectual at keeping things cold and a huge power hog. When turned on it used 3 amps all of the time.
The Engel keeps everything very cold. It has a thermostat with 1 to 5 (5 being "freezer". We set it at 2 and found ice start to form in some of our beverages.
We don't have a great way of measuring total power consumption over 24 hours. However we only have 80W of solar
and two marine batteries. We operate one of the marine batteries at a time and switch batteries every two days. For this reason we are very sensitive to power consumption.
The Engel only runs some of the time (seems to be less than the 30% advertised) and uses less than 2 amps when it runs. On average I would guess the average power consumption is a miserly 0.5A 24/7 when used as a fridge on setting 2 in our current
conditions (NE USA summer).
There a several models. I would avoid the Engel MD-14. From the data and reviews
I read it has different engineering and just is not nearly as good. The larger MT-17 and MT-27 are larger but use less power. There is a fantastic chart here:
