I was trapped on a cruise ship recently when my CPAP machine failed me. Four nights of torture. I'm sure a lot of it was psychological (anxiety) but I could not sleep as well.
If you are the least bit handy you could pull the battery from your vehicle, or just keep a sealed lead acid battery handy and charged. The ResMed 12 volt converter is a must, along with the adapter with a cigarette lighter socket on one end and a pair of alligator clips on the other other so that you can connect directly to the battery.
You may find the Jackery more convenient, it has a cigarette lighter socket so you can plug the ResMed adapter directly into it and skip the alligator clip adapter.
Without the ResMed 12 volt adapter you are wasting energy because you are using the Jackery inverter to convert DC to AC, and then the power brick on your CPAP machine to rectify the AC back to DC. A of lot energy is wasted there.
Do a test night to see if you have enough power to run the CPAP machine and the humidifier all night.
I also recommend a back up CPAP machine. You can get one pretty cheap on craigslist, just make sure you know how to get into the clinicican's menu and read the run hours. Don't buy or at least get a significant price reduction if the run hours are high. Figure 5 years of use at 8 hours a night as an estimate of the machine's lifetime. That's roughly 15,000 hours. Bring your own hose and mask with you and test the machine. Make sure it runs quiet and doesn't smell like it's been in a smoker's home. Often you find brand new machines. There's a large resale market. Something to do with Medicare not being allowed to provide used machines to patients.
