Boondocking with a CPAP device.

Just wondering if anyone has a solution to running a CPAP medical device while camped without power? I'm taking a month this summer to travel in my motor home. I'm a complete newbie but I'm thinking I'm probably not the only one traveling with this type of device. What do you use to power yours? Looking for tips, not looking forward to sleeping without it.

My unit has a 12 volt cord available for it. Use your coach battery, not start battery, to power overnight. The humidifier will draw a lot more current, I would recommend you avoid its use.I have 2 machines and the newer res,Ed one draws half the power of the older one.

6 Actual (DW) uses one (Icon model with humidifier) And she can use the whole unit on the battery pack they have. Only problem is they are expensive. I agree with B&B - see if you can get a 12V cord but you will have to go without the humidifier I believe

get an inverter, an extra battery, and a battery monitor and you should be okay.. how many amps goes the CPAP draw? From what I can tell it can be from about 1.5 amps without a humidifier to 5 or so amps. an 80 am deep cycle should be enough for one night assuming max draw, up to several night at the lower amp draws.

I believe the older (5 yrs) ResMed are 12v, BUT to run on battery (cigarette lighter socket), they are wired with the center as negative which is just the opposite of normal. Ask me how I know after burning out fuses 2x. Finally they revealed their dirty little secret.

We traveled around Alaska for 1 1/2 week in a rented motorhome. I have a 12 volt plug that I plugged into the 12 volt outlet in the motorhome. I filled the humidifier, but didn't turn it on due to the power draw. It worked fine. Just had to be sure & remove the tank before travelling.
For use in our tent trailer and now in our hybrid I have used an AGM battery that I got from Cabellas. Last year I decided to wire in a 12 volt outlet below my bed where I had previously used the AGM battery. It works fine using my 6 volt battery setup on the coach. Just have to watch the battery level & charge with generator when it starts to get low. Just can't sleep without the CPAP. Gotta have it!

I've got three and soon to be four group 27 Interstate deep cycles feeding an inverter, When I get a chance I'm going to measure the actual amp draw on the line to see what I should be able to expect with regard to duration. I considered the 12V version, but my therapist made me feel like they were troublesome so I went with a regular Fisher Pykel Icon.
