I think they have the Airsense 10 rigged to not work unless you buy a ResMed gizmo:


I didn't do comparison shopping so look around for the best price. The above link was just to show a product.

Hi there, I tried to do this with my previous machine on my boat. It didn't work, despite using several devices. What I learned, is that the machine needs more than just electrical current (being plugged in), it needs a certain kind of current (certain sine waves and such) which isn't produced by your 12volt adapter/transformer. I ended up shelling out the $975 for the approved CPAP lithium battery, and it worked like a charm. I suggest you call your manufacturer and ask if they have a special battery for your machine, or if they know of one which works, and follow their guidance precisely. You'll soon be sleeping on your boat!

I use a secondary 12 volt marine battery, with inverter to run fridge, lights and chargers in a VW Eurovan. Solar panel recharges battery if we are not driving. Have camped a couple weeks at a time and Resmed Airsense 10 works perfectly.
