I wonder if the reason why it kept power cycling is because the ResMed 11 was drawing too much power? I read online on some reviews that it could happen with these third-party adapters, one of which I was planning on buying to also use with my EcoFlow River 2. It sounds like if you turn off the heated tube or don't use one altogether then you have a much higher likelihood of everything working fine. I haven't found a proper 90 W DC-DC adapter and just have found the 65 W adapter so that would explain why the CPAP is asking for more power because it's used to having 95. I think turning down humidity and maybe turning down the heated tube all the way to off may prevent the power cycling. Have you tried that?
I never did figure out the issue so I gave up. And yes, I always turned off heating and humidity.
But I bought a CPAP battery off Amazon that has worked very well for the last year. This one:
https://www.amazon.ca/dp/B0C13MWK4G. It comes with a power cable for the AirSense 11, and I can get 2-3 nights of usage from one charge. Highly recommended!

Thanks! Those batteries are expensive! I'll give the adapter a go and see how I get on with it. There are a lot of people posting my positive experiences when turning off the heated tube and turning down humidity so hopefully I might be one of those lucky ones.

They aren't cheap, but if I get a few years of usage out of mine, I'll be happy.
I reached out to Ecoflow support last year around the time that I was asking questions here and they told me that the adapter would not work. I wanted to try it anyway, so I ordered the Resmed adapter and guess what? It did not work. With either my Ecoflow Delta (the orginal 1300) or a newer Delta 2.
I hope you have success with your River 2.

I use an
EasyLonger ES960 which includes DC-DC cables for various CPAP machines (e.g. Philips, Resmed). I got 3 nights (26+ hours) at an average pressure of 13.65 cmH₂O on my
Airsense 11 and still had bars left on the power meter. The ES960 can also run in
pass-through mode and will take over if your house power fails.

That's the same one that I use. I noticed yesterday that they have a newer version available that shows up in the Amazon link I posted that has a few feature upgrades.

This!
One of the most under-rated features for a battery backup.
- Allows one to run the CPAP through the backup all-night, every-night. Now if there is a power-failure, it switches over to battery and you sleep through it.
- By drawing off the grid, you are not cycling through charge/discharge (albeit small). This does reduce the life expectancy of the battery,
I've waken up twice with my clocks flashing and my computer abruptly shutdown. No uncomfortable, anxious, breathless wake-up. No trudging around setting up my battery.
Caution though, many battery backup do not pass-through if one is drawing from a DC source, only AC.
Therefore: I continuously plug my CPAP using AC. In the event of an anticipated power failure or even a good probability of one, I switch over to the DC-DC converter for the more efficient use.
Battery Backup: EcoFlow Delta 2
