That is fine, but I need a Bipap. Insurance is renting me an AirCurve 10, and they do not care what happens to me if power goes out! But I do.
MJ, the PRS1 60 Series BiPAP Auto would give the same therapy at 12 watts. You might be able to find one at a pretty low cost. I have one.
I have parts on the way to be able to power Resmed AirCurve 10 Vpap from strictly battery power. No inverter needed. Told I will probably draw 8-10 watts/hr id humidity and heated tubing is not used. Most my batteries are 24ah to 40ah in size. 2 - 40ah batteries in series has almost 200 watts of power. That would equate to about 20 hrs of operation per battery charge. I have a number of 24v chargers from my mobility devices. I could even run setup as a UPS. Charger to batteries to device, if power goes out, batteries supply power, if AC comes back on, charger auto recharges batteries. Not as expensive as paying over $700 for a refurbished backup machine.
We just needed to figure out what it was that Resmed did to make is so they thought, only they could provide power for the machines.
I am considering using 47k ohm resistor to center pin only on power-up. That would cut down battery drain slightly and not mess with data stream voltage levels. Which may be why Resmed is using 3.3v converters.
I will get there, and much thanks to these wonderful engineers helping us.

Wow, I really messed up on my est. power. 24 x 40 is about 960 not 200w
So at 10 watts/hr that would be 96 hours.
But I want to power 2 machines off one set so probably around 48 hours for 2 machines.
Parts starting to come in now, So over the next week or so
