Need battery operated CPAP for camping

All she needs for that is a 12-volt deep-cycle battery and the 12 volt Respironics cord that you can purchase online, as described in this post.

The old REMstars have a separate input power jack for 12 volt power. They can be operated with 12-volt power directly without the need for a transformer or power inverter. The transformer is built into the machine itself, which is one of the reasons I call my old REMstar Pro "The Tank" - it's huge, heavy and built like a tank.
Okay
i've been framed by the dust bunnies. the little hole directly above the 120v plug hole was stuffed with dust so bad that it looked like insulation so i never thought it could be a place to plug in a transformer. a blast of air in the hole changed my thinking. plugging a 12v source into it proved you are right. i've had this thing since 2001 so in the beginning i may have known that was a power hole and forgot. sorry for any confusion, folks.
Oh-jeez
I've finally done it. the first documented case ever of me being wrong, in this thread at least.

From what I've read, a car battery ought to last three nights, especially if there's no humidifier. If it were me, I'd consider buying a new battery for the vehicle, install it, and bring the old one along for your CPAP. That way, if something goes wrong, I'd have the new battery as a back up.

I would much prefer to take my old cpap machine, so it is wonderful news that I'll be able to do that by plugging a 12v source into it. Now I just need to figure out how to recharge the 12v battery so it will last 3 nights if that is possible. Thank-you all for your help!

Thanks

I purchased a 12 volt lithium-ion rechargeable battery that weighs about 7 pounds which I use with a cigarette adapter to power my respironics cpap when I'm backpacking or camping or traveling where I don't have an outlet to hook up to. I can generally get 4 to 5 nights out of a single charge. The model number for the unit I purchased is ow-12-c266 made by owell industries if you want to research it on the internet. Enjoy your camping.

the only 2 places i saw that showed a price were $236 and $289. i'm thinking of hurricane season and think a gas generator would be more cost effective than buying 2 of them. actually sleeping in the car post high winds would be better yet. the very high winds only last a few hours, but the power could be out for days.

Yeah, I saw the price, too. I can get a decent small generator for that. I don't go camping but we do lose electricity a lot lately. It's such a new fangled thing in these parts. /sarcasm

Yes, good to know that it lasts that long....I've been debating plunking down money for one of those.

Figuring that something that would probably be easier to get on in my carry on than a 55Ah AGM Deep Cycle battery....or just carry in general.
You may be a dreamer, but I'm The Dreamer, the definite article you might say!

I plan to rely on a car battery when the next hurricane comes around. That way I can recharge it by sticking it back in the car.

We had Alicia in 1983 and then Ike in 2008. May it be another quarter century before we have a power outage like that again. They each lasted at least a week, maybe 10 days, if I remember correctly.
