This week when I get the time ( or remember) I'll dig up my little
dorm refrigerator, and hook it up to an inverter with a 12'v battery
and see how it kicks on. I'll probably have to use the 1500w inverter
seeing I dont' think the 300w will even allow it to start. I'll put
amp draw meters in the 12v. line to see how much it pulls from the
battery including the inverter.

Kinda like to know myself.
