Cpap high altitude and cold

[Whaledriver]

I was luck enough to get a ticket into the CPAP world. I have heard high altitude 9-10k they do not work well. Also saw some of the compact units have temp limits. I do both of these conditions. Any experience with success? Looking to use a relogy battery. Thanks in advance!

We stayed in an air bnb at 9600 last year with no issues. Granted the house was heated and I had power. I’m following along for other answers as well. I want to be able to rough it with a machine for a few days.
