dry camping with cpap

Thanks for all the replies....I checked my machine and it is AC/DC so I will be fine ...I have a Craftsman 7000 watt and 2 Honda 2000 generators that I can run during he day so my batteries will recharge each day...Now to get a dedicated line into the bedroom......Thanks again to all..Joe

I have been dry camping with a CPAP since I was diagnosed 7 years ago. All the methods described above should work. I installed two 12V Deep Cycle batteries under the bed that are dedicated to powering my ResMed unit with the humidifier. If necessary, I will run my Honda 2K generator during the day to recharge those as well as the RV batteries. The dedicated batteries are hooked up to a battery charger/maintainer that will have those batteries fully charged and ready for my next trip. There should be no reason for someone to run a generator during quiet hours/overnight to power their CPAP. Happy Dry Camping to you!

I also use a 12v power cord for my Resperonics System One Auto. cpap.com has 12v cords for most machines. They are all 12v. The brick in the 120v cord converts to 12v. Find a always hot 12v source under the bed and mount a power plug on the side of the bed frame. I use the humidifier and heated hose and the draw is about 5a.

I hate to say this, but it should be known.....If you have a Dr certificate for your cpap, then it falls under the ADA and you can run a generator anytime to accommodate your disability, without fear of reprisal. Now, do I recommend this, ONLY if you have a 1kw Honda or equivalent that can not be heard in the next site and NO other means to operate your cpap. I operate mine, including the humidifier set on 2, on my battery bank and have no problems going multiple days. Mine can be operated on either 120vac or 12vdc. I did install a dedicated 12v power point beside the bed, so I would not have to use the inverter, which is a power hog in itself.

If you don't need the humidifier no problem. I don't use the humidifier and my batteries will last for days. I use a 150 watt inverter that plugs into a lighter socket.

I used one of these to power my booth at fairs and swapmeets when no power was available. Electronic cash register, halogen lights plus a public address system all powered for up to eight hours.

You would need to determine how much power the Cpap uses and then calculate how long something like this would last. There are more powerful versions or you can use several batteries in parallel and connect an inverter to make your own. Recharge it with the generator.

I'm not too familiar with CPAPs, but my FIL has one that requires 12VDC. Look on the back/bottom where the power supply plugs in to the unit and see if the input is 12VDC. If it is, get an additional 12V cig plug supply cable from your manufacturer or online, or you could make your own! It would be a big waste of power to go from 12VDC to 120VAC then back to 12VDC.
