Camping with an ASV cpap

So....the Resmed VPAP ADAPT s9 is a 24 V machine. we were set up in our motorhome with a 12v plug and I had bought a 12 V cord for my DreamStation that fit it.

so...now what? I looked at $499 battery packs. yeah...that's not going to happen any time soon. do I have an alternative other than running our coach all night long, or hooking up a generator? we boondock a lot usually. next month, there's a 9 day campout where we will not have electricity.

I'm not quite sure exactly what your machine is, but I'm pretty sure it can be powered with the 12/24 Volt Converter from ResMed - make sure its the right one for your model. It plugs into the 12 v socket and bumps the voltage up to 24V. Cost is about $90. If you can run without humidity, the load will be about 6 to 10 amp-hours a nights, so 9 nights will put a strain on the battery. I see some generator running in your future. If you have the particulars of your setup, I can give more detailed advice.

S9 VPAP Adapt.....plugs into my 12v socket next to my bed, that would work as it's already there. I would prefer humidity as it's cold where we camp sometimes, and my nose gets a bit cold without it lol on the DreamStation, our 12 v set up was good enough I could use the humidifier. Our motorhome has a bank of 4 6 V batteries, and a generator. we also have a solar panel which helps. thank you for the simple explanation, I googled and my brain started to hurt

I believe this is what you are looking for.

So the basic "4 6 V batteries" is usually 4 Trojan T105s, or equivalent, for a total of 425 Amp-hours. I have the slightly larger T125s on my boat. You have plenty of power for the cpap, but you'll have to keep an eye on the usage. Without humidity, the cpap will probably be a small part of battery usage, assuming you run lights, computers, radio/tv etc. But with humidity it will be a major load, perhaps the largest on the RV.

we're used to running the generator occasionally....a lot less since we got the solar panels.

If you get a new machine it will likely be an S10 which takes a different DC converter.

Just buy the appropriate 12v cord for your ASV.

I lived full time in my motor home for 5 years with an S9 Autoset then a PRS1 960 ASV.
I had a Magnum 2800 watt pure sine wave inverter and six 6 volt batteries.
We had 2 TVS, 2 DVRS a desktop computer, residential refrigerator etc.
We ran the generator a couple hours every morning while preparing breakfast and a couple hours every evening while preparing dinner.
No special adapter required just the 110 volt power brick.
If you don't already have an inverter you can buy an assortment of small ones ranging from 100 watts to 1000 watts for $75-400. Just be absolutely sure to get a PURE SINE WAVE unit.

my husband said it won't work (the converter) as we have a 12v plug. and, that we need a 12v cpap. *shrug* it's a 24v machine and we have a 12 v plug I guess is what he means.

I thought it would convert it TO 12 v...thought that's what the plug does?

this is confusing.

I have been told not to use an inverter because it "wastes energy" we used one for a while though and it worked fine. we just had to charge the battery a lot lol

The way my setup works is like this...

I have a 24V machine. I purchased an adapter that takes 12V from a battery and ups it to 24V for the machine. I just hook it to the battery, plug the machine in and it works.

I would have to bring a battery in our bedroom in the motorhome? ugh....

The cable Prodegyplace mentioned will plug into a 12 volt cigarette socket and power your machine.
