Request for updated CPAP battery info 2025

I am a new CPAP user and I have read the previous thread from 2013 on power options. With the new things CI has been doing, Li-on batteries, on-off power switches and solar kits, is there new info on powering a CPAP with or without the humidifier? I used my Bluetti for one night recently when boondocking and it ran the Bluetti completely down. We have a 2009 560, but we don't mind putting money into it if it will be workable for me.
Right now our power options are a medium sized Bluetti a smaller Jackery, an AGM battery, a solar panel Zamp 120 that came with the teardrop and a suitcase solar panel that came with the Bluetti.

Holly Bee, I purchased a battery last year specially made for CPAP machines. It is called the EXP96PRO. It is a lithium ion battery, approximately 307wh and I typically get 4 plus nights with it not using humidity. It is light weight and fits nicely in the headside cabinetView attachment 11743

Thank you for this idea. Have you ever compared it when using it with humidity to see what the difference is?

I have not, my guess would be one plus days.

All my experiments showed similar results as Glenn guesses. My current practice is to put a splash of distilled water in the humidifier chamber but leave it turned off, sometimes called “passover” humidifying. It’s not much but it helps.

Since writing about my experiences and trials with CPAP power I have:
Replaced the smaller Victron SuperCycle pony battery with a 50ah lithium that I keep in the headboard cabinet.
Added a folding Renogy 100w “solar suitcase” that I take on off grid trips in the sun (Utah!), with which I have charged both pony and CI batts.
Kept the 100ah Victron SuperCycle as my trailer battery, with added CTEK 12v/12v alternator/solar charger. With that charger upgrade it’s a happy camper.

I’ve very much kept my belt and suspenders approach of both batteries, either of which can keep the CPAP powered for several days. It gives me real peace of mind that I won’t have to suddenly pack up and head for home or a hotel! Most of the campgrounds we stay in are heavily shaded and do not have shore power.
