use a pair of 12v batteries in series or a large 12v battery with a DC-DC converter to run 24V out for you.
Resmed will sell you the cigarette lighter device for a pretty penny but it's most likely worth while.
Because you can easily get twice the run time on straight DC as opposed to converting DC to 110AC (with an inverter) then BACK to 24v DC to feed the blower.
This will save you some big $$ on the back end because you dont need to buy such huge batteries.
Definitely cool. Thanks!
