Need help with CPAP for camper
Fairly new to CPAP. The VA bought mine and it is strictly 110 volt. I thought no problem just get an inverter. Got a Schumacher 410 watt. Runs the CPAP OK but every time I take a breath in, the in...

WOW!! Did not realize so many folks used CPAPS!!!! Thank you everyone for your input. I was wrong about my machine. It is not 110 v, it has an inline reducer. Told you I was new at this!!
It is a ResMed H5i and it's 24 volts. 1.25A (FG) C and 3.75A (sys)
But being 24 volts then I am pretty much incapable of using it on my 12 volt camper? Sorry, electronically challenged.
You should be able to use it with either a 110v inverter as discussed, or with a 12 volt to 24 volt converter from ResMed. the DC converter may be easier on battery usage. I have used mine with a cheap MSW inverter in the past and it worked. But, it seemed like the pressure may have been a bit reduced and I am not sure of long term affects to the unit. I believe a true sine-wave inverter would be safer for the machine, which is what I am using now.
Due to my EMS shutting off power to my rig due to high voltage at night in a couple of campgrounds, I have gone to a standard practice of running my CPAP on the inverter even when I have hook-ups.
FYI - My current machine is a ResMed S9
