PAP machine voltage tolerance?
So I want to be able to take a PAP machine on my (future) boat or current RV.
Voltage on a sailboat can vary quite a bit.
Does anyone have any first hand experience with using a Respironics in such situations?
Yes I could probably find a spec sheet but what fun would that be and how will it relate to the real world?

I use my PAP machine nightly and I feel great!

RE: PAP machine voltage tolerance?
There have been many threads on this subject here and elsewhere that show PR products work well on direct 12 volt battery power as well as inverted 110-220 AC power. The power requirement without the heated humidifier varies with pressure, but is 0.5 to 2.5 amps on direct 12 volt DC. As you know 12 VDC actually varies from just under 12 volts for a depleted battery source to about 14.2 VDC on a vehicle with alternator power. No one has reported problems in this range. Shutdowns seem to occur if the voltage drops below 11 volts. On shore or at a RV park, most boats and RVs switch to AC power, and you machine would work normally from the outlets.

I operate a PRS1 Auto 550 or M-series Auto without heated humidification on lithium ion battery power on the motorcycle. Philips respironics sells direct DC power adapters, but you can fab one for much less. It's just a coax plug (center hot).
