between midnight and 8AM ,one 12v LED kitchen night light approx 7w and the fridge
no fans, no PC etc.
consumed power was 28 amphrs, according to the DC power meter
that amounts to 3.5 ampHr per hour and a combined ? duty cycle of approx 35 percent
600MA for the 7w night light = 4.8ampHr
so 22.2 ampHrs for the fridge, 2.775 amphrs per hr or 27.75 percent duty cycle ?
if i'm doing the math correctly
this based on a 10amp draw while running, at the end of cycle its closer to 8.5~9 amps just before cycling off a tapered draw, including that would probably raise the duty cycle another 1 percent or so, not the amphrs, just the actual run time percent
