CPAP Machines RV's

When we go camping, the one thing that never goes along is an alarm clock...lol

...and the cell phone stays off unless needed, which is rarely.

With my current rig I simply run a 600 watt pure sine inverter powering the whole rig at night. Runs my runs my S-9 Vpap through the night without any significant drain on the batteries even if I run the heater. The inverter is also powering our cell phone chargers, an alarm clock etc.

With our previous rig which we boondocked in almost exclusively without solar I had a separate group 24 battery running a 400 watt pure sine inverter that powered my machine. If we were only going to be camping 3 or 4 nights on long weekends which was our most common type camping I never bothered with charging the battery back up until we got back home. It would make it 4 nights before hitting the 50 percent SOC level most of the time.

My wife and I both have S8's and we run both every night on the Aims Power 1500 watt inverter that's hard wired to a 110 plug in the bunk. Never an issue and I have no solar, just 2 100 ah agm's in the battery box and my 2000 watt inverter which I run 2 hours every evening to recharge the bayyeries.

I can't do solar. Where I camp mostly, it's under a tree canopy in the woods.

\Don't know what a Roadtrek is however a camper is a camper to me.

I am trying to figure how to get 2 Cpaps in a Roadtrek and have come to the coclusion we will just pull in to a CG every night when possible.

Initially I used my Res Med while inverting, no issue because I have 400 watts of solar and 6 batteries in my bank, with a 2000 W Pure Sine Wave. Now I use my new battery run tiny sized Res Med. Great set up.

ResMed CPAP battery usage guide

ResMed warns against using the power inverters with with the heated humidifiers for most of their CPAP machines including S8 an prior models. Damage may result. Review the guide for usage with your machine.
I have S9 which ResMed says is okay and have used an inverter with. But I also have the 12v to 24v adapter by ResMed. At the time my insurance paid for it.

If you are paying over a grand for a resmed cpap you might try CPAP.com who will wholesale price the machines for about 450$. I installed two 12 batteries under the bed. The resmed has a 12 volt plug with current limiter that plugs in to a liter socket I installed. Charging the batteries is with a 12 volt, scooter charger that again plugs in when in use. Good for about 3 nights use. Recharge in hrs.

I actually have 4 different machines so needing another one is probably not in the cards. The only one I bought outright was the S8 and I bought that from Wright and Filippis about 10 years ago or just when the card readers came about and I think I paid at that time 700 bucks or so and my BC reimbursed me most of it. All my other machines I got through my hospitalizaation and from family. The rest of the family wated the newest and best so I got theirs, no issue with me.

I get my consumables from either cpap.com or the cpap store, which ever is less or on sale and I direct submit to Meidcare BC/BS and get reimbursed.

The S8 is fine now that I have a pair of BPS Li-Ion packs, charger and cables. I'm good for 3 days in the pucker bush hunting.

In the Rv, the PSW Inverter does the job and I'm a happy camper... So is my wife, I don't snore so she can sleep...lol

I have been camping using my CPAP(Resmed S8 + Humidaire 3i) since 2008. I need the humidification and almost exclusively dry camp. My solution was 2 Group 27 batteries connected to a 300/600W pure sine wave inverter to power the CPAP. When we had a 5th wheel the batteries were stored under the bed. With the truck camper they fit nicely inside a "hamper" next to the bed. I connect the batteries to a charger/maintainer so they are fully charged for my next camping trip as the RV is parked next to the house and shore power plugged in. I can get four nights of sleep out of the two batteries without needing a recharge. If I camp longer, I use our Honda EU2000i generator plus a battery charger that I carry to recharge.
Yes I know that the CPAP can be powered directly from the batteries without an inverter, but you can't do that and use the humidifier.
And for you willy-nilly's out there, I provide adequate ventilation to the batteries when they are being charged.

I bought a 1000 watt PSW inverter for a fishn buddy and wondered how long it would run his Cpap. Thanks for posting. This helps

I think mine says 80 watts on the power supply.....so you have WAY more inverter capacity than needed.....which might be wasting some battery power and it is the battery capacity that you should be worrying about.

P.S. Res Med now has a unit that runs directly on 12 V. I have one. With the appropriate power cord, it works fine.
