Has anyone tried using one of these small Apartment/dormitory style refrigerators with an inverter? I canít seem to find the specs. For this particular model (3.1 cu. Ft.) but I have found similar size unitís electrical data. They run on 120 volts at 1.53 amps. Doing the math that works out to 183.6 watts. Then I believe that there is another factor that needs to be multiplied X 10 for DC power thru the inverter (120)? If that is so now I am looking at 1836 watts. So this appliance would run ok on a 2000 watt inverter. Is that X 10 factor a constant load?

I found this information on an RV refer. that is made 120/12 volts:
"AC/DC Compressor Style. The AC/DC compressor refrigerator can be run up to 30ļ out of level and requires only minimal ventilation. Operating on 120 volt, it will pull between 0.4 and 0.975 amps, depending on the size of the refrigerator. The 12 volt amp range is between 3.5 and 6.0 amps. This style refrigerator, which uses a motor, can only be operated on electricity, not propane.
Then Why? Why do probably more than 95% of RVs come with the propane style refrigerator, when they are so inefficient on 12 volt and so temperamental? The answer is: propane. With standard propane tanks, an RV with a propane refrigerator can go for weeks without the benefit of any hook ups. The AC/DC compressor style, although much more efficient on 12 volt than the propane style, will barely last 24 hours with a standard battery, without recharging the battery. To be truly independent of outside power the RV would have to have a lot of batteries or some means to constantly charge (in a significant way) a few batteries.
There is a definite need, however, for the AC/DC compressor style. Any situation where the proper ventilation requirements for a propane refrigerator can't be implemented (such as many boats) is a perfect candidate. If 12 volt is going to be the only or main power source, then the AC/DC compressor style is the only way to go. If it is known that propane will never be considered as a power source, then there is no reason to put up with the requirements of a propane refrigerator."
I doubt if I would ever be in a position to not be able to plug-in or run my generator to keep my batteries properly charged. If I was it would be easy enough to unplug the Refrigerator and transfer the contents to an ice chest or dispose of the contents rather then ruin the deep cell batteries.
Why isn't everyone running one of these with an inverter instead of the expensive propane models?
