Simplest is one of the Medistrom or other cpap specific devices, they'll be expensive, but compact and you can buy one that matches your cpap machine and give you about 2d if you disable the humidifier and any other extras like heated tubes. They're sized for the max power rating allowed on a plane, hence the only 2d thing.
Simplest that you can get at short notice is something like a Yeti power station and you can plug your ac adapter into. You'll need to size it up a lot more than the 100Wh ones because you're going to lose a bunch of power to the DC->AC->DC conversion.
Resmed's devices are typically 24v, which is extra annoying, since everything is usually 12v. If your device is 12v, you can use a car/DC adapter and you won't pay a conversion penalty, usually the power stations have car lighter plugs in them. You might even be able to rig up some adapter, depending on how complicated the plug is (though, without Radio Shacks, I don't know where you'd find the parts locally to do that easily). If you have a Resmed, you'll need their car/DC adapter to convert from 12v to 24v and you'll lose a smidgen of power there.
If you go on the boards, they'll point you at the cheapest longer lasting option, which is usually some lead acid battery like an A1 size, not a starter battery type, but one that's good for continuous usage, and then the DC converter. Definitely heavier than the above, but you can size up to however long you need and the price is like 25% of the Li options above per Wh.
Also, the damn DC adapters, at least for the Resmed devices, are ridiculously over priced, which makes up a lot of the difference in price between a power station and the cpap specific device. The cpap specific devices usually have a USB port for charging your phone or whatever, but if you really have a bunch of other things to use, the power stations are better for that.
For my first camping trip with my machine, I went with a Medistrom and Webetop from Amazon: https://www.amazon.com/gp/product/B073J61T3Y but since it's never been more than 2 nights and not full night sleeps either (camping with younger scouts, they don't sleep in), the Medistrom has been my choice since then, also used it on planes and when I was in a British hotel that didn't have their normal plugs (apparently there is a separate "light" outlet type in the UK that was all that was available near my bed, luckily I had the battery for the flight over).
Medistrom also sells a co-pilot, which is basically a second of the same battery that attaches in series, slightly cheaper than two separate ones, if you need more time. They also work well as a battery backup if you often have power outages, ie leave it always in-line between the wall and your device. Though I do wonder how long it'll last in that configuration.
The Yeti's are typically rated well and more likely to be available locally. Depending on where you are, you might be able to get same day or next day delivery from Amazon.
I have a cpap. I actually have pretty bad apnea. I've used the same resmed for several years. I want one of the newer lighter ones but the insurance stuff was enough of a hassle that I've put it off.
One thing, depending on your cpap unit, do not take the humidifier with you. Just run the cpap part without it.
I used to use one of the big lead acid type batteries, that have a car jump start on them. It worked fine. At first it would last a couple of nights, but it got to where it only lasted one night, then less than a night.
So before last year's summer camp I decided to treat myself to a new battery.
OP, please listen to me. Battery technology has improved so much in the past few years since I bought that lead acid battery. You want to get a lithium ion battery like this https://smile.amazon.com/Webetop-42000mAh-Portable-Generator-Emergency/dp/B073J61T3Y/ref=sr_1_22?ie=UTF8&qid=1522954171&sr=8-22&keywords=lithium+ion+portable+charger
There are different brands of these but all are basically the same.
It is so small and light compared to a lead acid battery. It weighs maybe 3 pounds. It lasts two nights on my resmed 9 (without the humidifer) running on AC not using a DC connector for the resmed (this would improve time since it wouldn't have to invert to AC, but they cost a lot) plus a phone charge. This is so what you want. It is easy to carry and go recharge it. It costs a lot less than the "CPAP batteries" because they aren't marketing it as a medical device.
We rotate between three scout summer camps. All of had a place to go charge, some closer than others, and some have had lead acid battery packs exactly like the one in my garage to loan out. I'm encouraging our council camp director to just get the lithium ion ones. They will easily last a weekend trip, one or two charges gets through a week of summer camp, and they are comparatively inexpensive.
