Connecting a CPAP machine to a battery?

Well, the shielded cord for 12V Dream Station would not work with CPAP. The digital readout lit up, but then said "in correct power".

Not sure why yet.

Thanks for this link. Didn't know they existed. Just bought one online from Amazon. About $5 more but I could get it in 2 days. Time was short because we're leaving for Florida soon.

CPAP.com shows a shielded DC (12V) cord for the Dream Station available for $29.95. https://www.cpap.com/productpage/pr-dreamstation-shielded-dc-cord.html

I have an older Respironics System One machine and have used the CPAP.com DC cord for it for years in the RV with no trouble. It uses a cigarette lighter type plug and the regular 12V wiring.

Read the manual on your jump starter carefully. Some of them cannot handle the sustained load of running a CPAP. Here is a link from the Stanley website for the unit shown in your photo. I'm a librarian, good at looking things up, and not an electrician, so I'll leave it to you or your electrical pro to interpret what this manual says about the sort of load your Dream Station will create.

You may need the humidifier. Humidity here in SoCal has often been in the single digits lately and my respiratory system has really appreciated having that humidifier.

I don't know why I missed this, But I have been using that same plug to my older M-Series Respironics, Bi-Pap Machine for some time now in my 2005 Jamboree 26Q RV. I tried using a Battery jumper set up like the OP showed in the very first post. Didn't work. Contact CPap.com and talk to them they do know what they are selling and saying.
