Searching, and wbbeasly,
From your posts, seems you are running units 12vdc directly from your bats, WITHOUT an inverter. I do not have that option. Thus, my original question on inverter efficiency. Looking back, while people have given, a lot of info, none have seemed to know how efficient these inverters are.
Bottom line: Run a CPAP without heat and humidity direct from battery, no problem w/ 2 or 3 nights on a group 24 battery, according to actual users who have posted.
I, will be using a cheap Radio Shack 300 W inverter. How much MORE( than the approx 2 amp rating) current will this draw.
I have 2 Group 27's paralleled. If I could go direct w/o inverter I could use it for a week! Are these inverters really that inefficient so as to double or even triple the current draw. Doesn't make sense
