Use a CPAP?

We have never found it necessary to dry camp and have avoided considering same because I would not have 120VAC for my CPAP.

I have a small inverter that I could plug into a 12V outlet on the dash and run an extension cord but am worried about running the engine battery down.

I am sure there are a lot of CPAP users out there. How do you get power without running a generator all night?

Hello,
I have a small inverter as well. Would just use the trailer battery and kill it if needed. No Heater. Both DW and I have them, I am ready in case. I would wire up a 12 V jack to your house battery for this use.

I also have a generator now as well. Will run the whole trailer AC included.

90% of Cpaps are 12 volt . I bought a 12V plug and cord for mine from my cpap company !! this would eliminate the extra draw for you converter . look at the 120v cord that goes to your cpap, you see the small black box that converts the 120 to 12v than there's a cord that comes out of the box with a charging plug like the one in to your lap top . If you see that it's 12v go on line an order the 12 volt plug in. My friend has a kit with a portable 12v battery for tent camping !!

I don't have a motorhome, but do sleep with a CPAP and occasionally boondock with it. As B and B mentioned- turn off the humidifier; that uses like 3x the power than just the blower.

Otherwise, I did exactly what you said- a cheap inverter plugged into a 12v socket. I got 2 nights of use out of my machine and 1 night of furnace use out of my upgraded battery.

For me, I have to run an extension cord from our kitchen to the bedroom:

This is the best answer if you'll be doing this more than once or twice. Unfortunately, I couldn't find a cord for my machine.

We were on a dry site last year and had 2 visitors, each using CPAP machines. My camper at the time did not have a 12V plug and I don't know if the machines had 12v.
I have 2 batteries and a 750W inverter w/ 2 120v outlets (about $40 on sale at Harbor Freight). Brought a battery inside w/ the inverter, hooked up both CPAPs and powered each all night. Charged battery next day on my generator and they were set for the next night.

Just upgraded my cpap last year to a dual 110/12v unit and it has the option of a separate battery pack. I would suggeste contacting your supplier to see if you have a 12v for yoiur unit or consider upgrading

We installed a third deep cycle battery in the storage under the bed with an isolator and inverter. The cpap runs on it all the times. If the power goes out or gets unplugged it continues uninterrupted.
Dry camping we get a couple nights without worry.

I have been going to Football games for years and it is definitely dry camping. I looked on the Internet and found companies that see rechargeable battery systems for the CPAP. Works great...charge it during the day and use it at night
