Does anybody use a c-pap machine? How do you power one when camping? Is there a battery or something one can use?

Search the board without the dash CPAP not C-PAP. Lots of stuff

You're likely looking at needing a huge battery (1000Wh maybe), sold as a "solar generator" these days from brands like Jackery, Bluetti, Ecoflow, and others. You'll probably want a travel CPAP which draws less power than standard ones as well. A solar panel would help you avoid needing as large of a battery, but you can't always count on having sun. Like Miksilly said, search the forums, as there are many others who have discussed this before.

I use a transcend mini, which is perfectly fine, but I'm not thrilled with any of the options I've used to power it. I initially bought two of the transcend 2 night batteries, but they were pretty useless and the solar charger I bought with them was even worse. I then bought BPS freedom cpap batteries, which have been fine, but I've never had much luck recharging with a portable solar panel, so I ended up buying 5 of them so I can trip with them. I should look into on of those solar generators, but I'm already over $2k into cpap, batteries and chargers and really don't feel like spending more. Also, while you'll get more nights out of one of the solar generators, once it runs out of charge, you'll need a good sized solar panel and a lot of time and sun to recharge it

I have used CPAP on several trips. as well as on one of the Namakan houseboats. I had an old post on the CPAP web site about batteries & how to rig up an inverter and old meter. The basic theme of the thread was to avoid the expensive backup batteries sold by various companies. After much testing, weighing, cost factoring, etc.I put all this info in a spreadsheet which was posted online. The info is several years old, but the basic principles still apply: the best setup was smaller, less expensive lighter weight batteries you can purchase at any battery shop like Batteries Plus. The key was the voltage meter I rigged up using parts from an electronic supply house. It was lighter and smaller by far than meters I have that were bought at Home Depot. The meter was important because I could track the amount of voltage used by each batte try so I knew when to switch them. Like all equipment, it is crucial to test whatever setup you go with before go out. I don't know ab out your situation, but in my case bringing the CPAP was absolutely necessary since I had one of the worst sleep test results Mayo said they had ever seen.

I have thought of getting a travel CPAP, but the weight of batteries has really discouraged that idea. So I go without the cpap and hope for the best. I really only sleep for a few hours anyways.

Not allowed.
It has a motor.

A CPAP is a prescription medical device. I'm sure under the ADA it would be legal to bring in a generator to run it.

cpap yes. Generator no.

Anybody with a machine try a mouth piece as a fall back for times like going to the wilderness? Any success?

If you can run without the humidifier the batteries will last longer. I have a friend that uses a rechargeable battery that if you run it down it destroys the battery. He has a low voltage alarm on it. The alarm wakes him up and he changes the battery. He has been using the set up for several years. It also requires a special charger. Don’t store the batteries without having them ½ charged or more.
Batteries assuming yours runs on 12V

Many CPAP machines are 24 volts, I know both of mine are. They require a converter. I gave up after spending nearly $1,000 on batteries (plus $900 on the travel machine) and only getting two nights out of it.

If you search CPAP on https://www.hammockforums.net/forum/forum.php you will find what has worked for a lot of backpackers.
