Sleep apnea and dry camping?

I am wondering if anyone out there has a CPAP machine for sleep apnea and is
also able to camp without electrical hookup. If so, do you have a specific rechargeable power type box
that you use? Canadian tire here in Canada sells a bunch of different ones called "eliminator" so I know there are units out there, but I would like to find out what actually works, and lasts a whole night. My husband has severe sleep apnea and we can not go without.
A generator does not seem to be an option, as most campgrounds want them off at night.
Any help would be appreciated.

I have a Bipap machine, and I dry camp about 3 or 4 times a year. There really isn't a good answer to your question, however I personally camp with a battery operated fan blowing on me at night, which helps at least some. I started out with a C pap machine, but Bi pap works sooooo much better. C pap is Continuous Positive Airway Pressure. Bi pap changes via a valve to have the same air pressure blowing in as c pap, but switches to allow you to exhale without the pressure still blowing. Night and day difference, to me!
SOME campgrounds may allow you to run a very quiet Honda generator for that- and if you pull with a pickup truck, and have a trailer, not a fiver, then you could put that Honda in the bed of the truck, install a topper, and face the back of the truck towards the woods. I doubt anyone would be disturbed by that. Those Honda's are really quiet. Check with the campground manager first to explain why you need to run it, but it is really pretty quiet. Randy

The first question I would ask is how much power the unit draws? Most appliances will tell you either how many watts and/or how many amps it draws.

I have a ~7 year old Eliminator power box that is still going strong; and I know it will power a 15 watt CFL bulb all night. But it typically is good for about 200 watt hours. So that means it will run a 200 watt appliance for 1 hour, a 20 watt appliance for 10 hours, or a 2 watt appliance for 100 hours.

I solved the problem by getting a machine that has a built in battery pack. Will run on 110, or battery. Battery runs for about 10-11 hours. Good unit. Keep it in the RV.

the CPAP is one of the reasons i don't dry camp.
i have thought abt wiring up a DC connection in the bed room and running mine. i also use a heated humidifier.
i would think u should be able to make the night on ur trailer battery but have never tried it.

every time the power goes off here, i threaten to get a computer UPS and put between me and the power co.
if u run it on an inverter, the inverter power consumption will also have to be considered.

CPAP machine
I have a Sunseeker 3100ss with 2 batteries.
When dry camping I use a Wagan 180 Watt Pure Sine Wave Power Inverter, that plugs in a 12 volt out let in the beb room.
It will not handle the humidifier on maxs but on lows seem to work.
To run all night ( 8 hr) on batteries depends on having a full charge, and what else might be running at night. Also check the watt requirement for the CPAC.

Posts: 1,264 has a battery pack for almost all machines that lasts 18 to 24 hours run time for around 300.00. Wow, I never knew these were even available for cpap/bipap machines! Thanks for the info dimurrrw! Randy

I haven't used my CPAP during dry camping, but I have a battery pack unit that I keep at home for those rare times when the power goes out. My battery pack will run the CPAP for at least 2 nights without recharging.

It also comes in handy for running any DC appliance that has the standard DC connector!

Some CPAP (or BiPAP -- no difference) machines will accept a DIRECT DC connection. I have a DC adapter that looks like jumper cables that I could also use by connecting to any standard 12-volt battery.

I've bought my machines and supplies from CPAP Plus Direct for many, many years and they are a very reliable source.

Here's a link to their battery backup page: CPAP Supplies | Miscellaneous CPAP Supplies

I use a Respironic M series C-Pap machine. It will work on either 110 or 12 volt. I have the 12 volt cable for it. Although I take the humidifier with me I make sure that it is turned off as it would pull too much power & drain a battery overnight. I purchased an AGM battery from Cabellas to use in the trailer as we frequently dry camp. The AGM is a glass mat battery that is sealed so won't damage things like a liquid acid battery would. (Just got back from 6 day trip dry camping). I have used this battery for 3 nights in a row without needing charging. I put it on the generator charger once this week to keep it charged up. It works great. Don't let C-Pap use stop you from dry camping. By the way this AGM battery is also my power backup for when the power goes off at home.
