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.

Your husband is *WRONG*. the Resmed 12V converter works with... 12v.

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

this is confusing.

The ResMed converter will work. I have the S10 version running from a 12 volt battery and it is very efficient.

See my earlier posting with the link.

good deal then I kind of thought that it made sense that using a 12v cord with a 24v cpap would work....it converts. that's what it's supposed to do.

The converter has a 12V lighter plug like you could use in a car. I think it also comes with a socket & clips to adapt to any 12 volt source.

Barb as the others have said get the Resmed DC adapter it will allow you to plug it into your 12v supply buy your bed and provide 24v for the S9 Adapt. But if your insurance is going to get you a new ASV they may provide the Aircurve 10 ASV which uses a different DC adapter I don't want you wasting your money on an adapter you will only use once

true....I want to get some type of battery back up pack for when our lights go out....they're quite expensive though
unless we create a 12v plug for our house somehow...has anyone ever done that

I know you don't want to hear it but there is another option.

Your DreamStation at a pressure of around 15 with no exhale relief and no pressure support.

You said several times that a battery backup is quite expensive - but a battery plus charger is between $80 and $200 depending on size. Is that too expensive? If by "12v plug for our house" you mean a battery on a charger with a socket, then yes, that's exactly what I have next to my bed.

The possibility that you might get an upgrade doesn't have to paralyze you. If its only for one trip you can use a small inverter (you should have one anyways on the RV). Just understand you'll use almost twice as much power as with the converter. Would you be keeping the S9? Maybe you'd use that for travel.

Indeed... I've got one of the s9 12v converters... they work perfectly.. and they give you much longer battery use than an inverter will. (up to 2x as much time)

the battery pack I looked at at first was $499...there is a cheaper alternative called the Freedom which would work with the 12v charger for my resmed.
and it was $209. then, with the charger, another $65-75 or so...I think it might be a viable alternative....I have to save some $$$ though. if the power goes out, I could just go to the motorhome and plug it in

No, dear, the cheaper alternative is a 60$ scooter battery, which will get you four or five nights without the humidifier. plus a charger.

These packs you're looking at are very expensive because they are using Lithium cells to save weight. This is very handy if you need portability, but it can drive the cost up by as much as a factor of ten! For home backup (and for RV/Boat/car camping) you can get far more power for less money with an AGM battery. For example, a scooter battery (as use by millions of seniors and safe for indoor use) that has 35 amp-hours capacity can be had for $65. A charger plus a few minor cables adds $35-$50. Assembly is "plug and play" - the most complicated bit is bolting the color coded cables to the battery. A lithium based pack with this much power would be about $500. AGM batteries come in a variety of sizes so you can get anything from 4 to 100 amp-hours, price and weight varies appropriately. These batteries are used in everything from UPS power supplies, jump starters, scooters and wheelchairs, to lawn mowers, etc. Unlike tradition lead acid batteries, they are sealed and can be used upside down, and don't vent any gas. With a gentle charger, they are perfectly safe at home. The major downside is the weight, so a while an AGM battery that can power your pump with humidity through a 2-3 day power outage may be affordable, you won't be moving it much!

For more details, look at the thread linked to in my signature. A post near the bottom of the first page lists the details of my setup.

I use an AGM battery as a backup but, because I want it for power outages, I bought a 100 watt solar panel system to charge it.

I can get several days (no heat or humidity) from the AGM battery without recharging, if needed. I live in a rural area so I do not want to depend solely on the power grid for charging.
