Thanks. I just ordered two of the 12 volt power supplies from the cpap manufacturer. I’ve also bought two sockets and materials to install. We need to run two machines, but I have two 12 volt deep cycles. I think we’ll be ok. One night is all that’s required. I can charge during the day.

The biggest power hog is the humidifier. My ResMed S8 has a detachable humidifier that I only use in the dry winter months. Without the humidifier, you should be able to run two units for two days easy. I keep a booster pack charged and ready to go just in case

My DW uses a CPAP. We use a Schumacher 1100 (with an inverter) to power hers when we're dry camping. It's "dedicated to power her CPAP only and doesn't power anything else. If she uses the humidifier, she can get one night's use. If she turns off the humidifier, she gets 3+ nights on the power supply.
You might have a problem with the increased power required to heat the water for humidification. Experiment with your battery system, maybe it'll run the humidifiers on two CPAP's for a night, maybe it won't (depending on what other drains are on the batteries from other RV related systems based on the way you camp. If you have an excessive battery drain, consider trying without the humidifier. It tripled my DW's CPAP time by turning the humidifier off.

I’ve thought about that. Ours need the tank installed, it’s part of the air flow, but I can turn the humidifier heater off. I’ll try them that way first. Thanks!

Wow. Great information, thanks! I love all the responses I’ve recieved. This forum is so helpful. I’m just returning to camping and this is my current wife’s first RV and she’s loving it. As long as I can get past these little hurdles we can hit the mountains! Empty nest celebrations!

We will be traveling here shortly and may be off grid a few nights. Any suggestions? I did purchase a 150w portable battery from Amazon but it would only power the unit 6 hrs.

Great unit! Runs the CPAP all night. Recharges quickly, Comes with all connectors and can recharge your cell phones!

simple answer is to get a generator or not go off grid. Also, i think your truck has a 110volt plug, just run that if you want too.

All the inverters in trucks that I've seen only operate when the ignition is turned on. There are alternative "work arounds" to still go off the grid, you (actually the OP) just needs to explore which "work around" is best for his needs.

So if I get one of those battery/jumper power packs she would be able to plug into the 110 and run all night without the heating element.

Yes, with the qualification that it'll ONLY supply power IF the battery pack in the battery/jumper power pack is large enough. Ours is a Schumacher 1100 and we can power one ResMed CPAP without humidification for 3 days before needing to recharge.

My DW's ResMed requires 24 VDC or 120VAC. That's the reason I bought the Schumacher with the inverter. Trying to adapt or build a 24VDC supply that's reliable and portable enough for use in a travel trailer is daunting and/or expensive. The ResMed battery system approaches $300 and is only good for 1 night before recharge. The Schumacher was $79 on sale at Lowe's and provides 3 nights of power before requiring recharge. For me, it seemed like a "good enough compromise"....

Mine and my wife’s resumes have a 24 volt input. For our machines they sell a power supply with a 12 volt input and 24 volt output. I believe I paid $160 for 2 supplies. Then ran 12 volt accessory sockets, (still hard to not say cigarette lighter socket), 1 to each side of the bed. With 2 12 volt group 24’s, I had no issues with one night. I’m positive with no charging I can get 2+ nights. 2 machines, $200 and we can sleep easy.

Brian,
Thanks, good to know information. I'll check out that 12:24 VDC converter.
