We plug a 400 watt inverter into a 12 volt plug connected to the house battery. More than enough power to run my wife's CPAP for the night. The battery is recharged during the day while we're driving.

I ran mine off a 110 watt inverter plugged into the "cigarette lighter" plug on our Windjammer a couple of years ago. Did it twice with no problem. Didn't use humidifier. As I recall I did hook up an extra battery (the trailer just had the one) but I don't think that was necessary.

I purchased the 12v converter to use with a deep cycle marine battery since I use the CPAP on a weeklong fishing trip deep into Quebec. The converter costs about $82 online. I then mounted a 12v accessory plug on my night stand, ran a fused wire into my front storage box where I keep the deep cycle battery. In Canada, I can run the CPAP a week or more without charging. No humidifier or heated hose of course. Very happy with this setup.

CPap power

Got 12v plug from Radio Shack, tapped into my bed reading light wires and installed a 12v socket. Never had a power problem.

Using cpap with inverter

Just got back from our trip to Michigan. Bought an inverter at Walmart. We used it for the first time last night. It worked great. It didn't suck all the power out of the battery, and my husband got a great nights sleep!
Thanks to all for your suggestions. Makes life easier.

Many CPAP's will run off 12v. Just need a special plug. Ran mine off a motorcycle battery.

Reading the back of the CPAP, most do use 12v but is converted from the 120. My mother's was as simple was a trip to radio shack and she was using 12v in their Sunseeker.

Just be aware that not all units run off 12 volts.
Respironics and a few others do, but Resmed units use 24 volts.
