2.5 amps average, WHILE RUNNING. This has been verified with several
different ammeters. If you have one drawing more than 2.5-2.7 amps while
running, I'd recommend calling the manufacturer to complain.

20-22 amp-hours consumption, per day, is what I calculated.

The compressors definitely do draw more amps on startup - just like any
electric motor. I have a new SS 90-liter Vitrifrigo (same compressor)
I've just finished installing into my Karmann Gipsy - there were some
glitches in the factory wiring in the camper that caused the initial amp
draw to be too high, causing the compressor to cut out on every start.
Perhaps I will add an ammeter to it as well, to quash doubts re: the amp
draw?
