Yet another camping question

Some of the CPAP machines specify pure sine wave. I don't know about yours.

Thanks
I'm okay with the inverter I bought. Previous to going to town yesterday to shop, I emailed Fisher Paykel asking for their recommendations. They emailed my back within an hour, I took that info with me to Canandian Tire and the manager there helped me with what I needed. Sometimes it helps to be a "helpless old lady", you get all the help you need.

So does the breathless blond with big eyes...

Being neither I have to figure it all out for myself.

You play the cards you're dealt. All those years of college have to be good for something, right?

All Fisher Paykel, Respironics, and DeVilbiss IntelliPAP xPAPs and humidifiers will work from a modified sinewave inverter. ResMed is the major brand that has problems with inverters; depending upon the model, ResMed heated humidifiers either require a true sinewave inverter or should not be used with an inverter.

Unless you are using a large battery, the use of an inverter is not a good idea. Heated humidifiers draw considerable current and will drastically reduce the run time of a battery.

DeVilbiss IntelliPAPs, Respironics, and almost all other common xPAPs will work directly from 12 volts DC with the proper DC cable. Many Fisher Paykel CPAPs will not work directly from 12 volts DC and there may be a few older Respironics BiPAPs that will not work from 12 volts. It is better to run the CPAP directly from the battery because the use of an inverter will shorten the battery run time by about 10%. Operating the xPAP directly from the battery will also greatly simplify the power circuitry.

Thanks for all the info. I still don't know what I'm going to do, but from what you all are saying, it looks like it will have to be a battery and connector. As for the inverter- since my machine is resmed, I think I have to use the one I linked to. If I turn off the humidifier and just add water to it so the air blows over it, is that the same energy draw as not having a humidifier?

Putting water in the humidifier and not turning the power on (or not plugging it in) is the same as using a passover humidifier -- it puts some humidity into the air, and it doesn't draw power.

I do not use my Humdifier when I am camping for that matter I have 2 of them and have never even used them, even at home. I run my Bi-Pap on a 12vdc plug, that I puchased from Cpap.com https://www.cpap.com/productpage/respir ... -cord.html.I also have a 2000w Prosine Inverter, and 3 100w solar panels. Before I had the solar panels installed I could run my Bi-Pap for 5 days before I needed to charge the battery's Being as my Bi-Pap will run off 12vdc. I do not need to use the inverter. If I ever get to where I have to use my humdifier at all times I will then use the inverter.
Good luck

I have been on CPAP for 15 years and I don't use a humidifier. A few years ago I got a new CPAP with a humidifier and I stopped using the humidifier after a few weeks because I didn't like it - it felt like I was breathing through warm, wet, flannel..
