Need help with CPAP for camper

Fairly new to CPAP. The VA bought mine and it is strictly 110 volt. I thought no problem just get an inverter. Got a Schumacher 410 watt. Runs the CPAP OK but every time I take a breath in, the inverter runs then quits when I breathe out. The cooling fan on the inverter is noisy and very annoying since it does not run constantly.

I doubt if my VA Dr would write a prescription for a 12 volt model that I could go buy myself.

So, just wondering what others do. 12 volt machine or are there quiet inverters or put up with the noise?

Thanks.......DJ

I really.....really doubt that your cpap is strictly ac. With the extreme possibility of getting water from the humidifer into the fan motor it would be such a hazard they could not sell them. I have done this numerous times. I believe that if you look closely you will see that both the cpap and humidifier are both dc units. I could be wrong but I don't think I am. Oh, I just turn off the humidifier and run on a 400w inverter.
