I bought a killowatt from harbor freight (I think that's what it is called) My 10.3 cubic foot refer draws about 3 amps on start up and about 110 watts while running. So far I have only used a couple hundred watts over 10 hours at night. I love that little meter it is super handy shows total watts used as well as instant watt measurement. Shows your amp draw and voltage.
That KAW is going to prove very useful. :)
The total Watts used over time is actually called WattHours, there is a difference. A 200W light draws 200Watts, if run for 2Hours you say you used 400WH.
You can roughly translate your 200WH into battery AHs by dividing the 200WH by 10.
The AHs drawn will be influenced greatly by the ambient temperature around your fridge. You should find draws around 60-90AHs daily at normal room temperatures. That was my experience with a dorm fridge.
