Running CPAP Without Utilities

My son uses a Jackery 1000 for his Dream Machine. It uses 6% of a full charge for one night. He also has the optional portable solar panel to charge it. He has a cigarette lighter type power cord that plugs right into the 12V Jackery port.

I was going to suggest a Bluetti, I knew there were others but could not remember the names, Jackery is quite popular. They are expensive but some of the larger ones would run the CPAP and an electric blanket for days on end, especially if you used a portable solar panel to top it off during the day.

Will something like this work? Jackery Explorer 290

I use a battery pack from the same company that makes the CPAP. Hooks directly to CPAP. Cost was $200. Lasted about 2 nights, then I charge it up with my generatotor. Next I purchased a GOAL Zero 400 lithium generator. I c@n run my CPAP 5 nights. Cost was $500. Plus I can use the Goal Zero for other thing# also. If you use a lead acid battery be aware of the gas that is discharged when you charge it and also very heavy. Lithium battery weight 10% of lead acid. I purchased a 50aH Battle Born lithium battery and it weighs 17 pound. I will run my CPAP FOR 5 days. Cost $525. Lithium battery do not discharge ant gas when charging. Battle Born batteries are guaranteed for 10 years. The best lead acid battery May run 3-4 years.

Thanks everyone for the info. Some good stuff. Looks like I have some options to investigate. Thanks again.

We both are on CPAP. When dry camping in the motorhome, we run the machines on 12VDC. The two T-105 house batteries will run both machines overnight with no problems. We don't mess with shutting down the humidifiers.
During the day, I run the generator long enough to recharge the batteries, run the AC, use the microwave, etc.
It works for us.

Only one CPAP here and my two T105's don't even show a reduction in charge overnight and I use the humidifier and a heated hose. My usual 1 hour generator run in the mornings for coffee and a little TV tops the batteries off again. Works for me.

A motorcycle battery will work.
A friend brought his CPAP on a week long canoe trip.

a hint for humidifer. on many units you can turn off the humidifier but leave the water chamber attached. so..... fill the water chamber with warm/hot water before going to bed and turn off the humidifier heat. you will still get some humidification from airflow over the water chamber.

And my CPAP has an optional insulating wrap for the hose, using that helps when the hose heat is not used and reduces power draw when the hose heat is used.

Run the wife’s ASV on the biggest 12v AGM motorcycle battery I could find. Bought the 12v converter with battery clips. No humidifier.

There’s plenty of info online for nearly every xPAP on clinician settings. Turning off the humidifier is a very simple change and has no bearing on pressures or other settings. I leave mine connected but the heat off so it runs like a passover humidifier.

With the CPAP I have the humidifier half can be unhooked and the hose connected to the back output that formerly connected to the humidifier. I bought a 12 volt adapter cable and I run that off a dedicated 65 Ah AGM battery. Without the humidifier the power consumption is low and I can run 5 nights no problem without recharging. Could probably stretch it to 7 if needed.

I found wetting the nose piece helps with the lack of humidifier.

Have dry camped about 25 nights this season with this setup.

you might be able to just leave the two connected and dial the humidifier down to off. it will then just work as a passover unit?

Doc wouldn’t enable the ability to shutoff the humidifier, said split it apart instead.
