Some use 24v DC and need a converter.
I've been using a C-pap machine since I was 32 I'm 56 now My insurance gives me a new machine every two years. I've sold some old ones on ebay and I have 4-or 5 machines in the closet. I've had so many brands I can't count. But they all worked like I said in my earlier post. 120v ac to 12vdc you simply unplug the 2' or so of the 2 prong 120vac cord and plug in a 12 volt power cord from amazon. And choose any one of many ways to use it in the RV. I bought mine years ago on Amazon it's been through 3 5th wheels and I'm not sure how many C-pap machines, and is still in my RV just in case I have an issiue with my inverter, and have to power it off the 12vdc again. Since adding solar I plug it in at night like I was home.
