12V to 24V Fan-Less Converter Compatible with ResMed AirSense 10 Series CPAP Machines - DM90S10

We got this to use with a battery bank and Resmed Airsense 10 CPAP machine. We tried it with an Anker A1695 (25000) and it did not work. That was because the Anker is NOT actually PD 100 output. We tried it with a true PD 100, 27000mah battery bank and YES, it will power the Airsense 10 (without the humidifier) for at least 2 or 3 nights (probably 30 hours). It came with all the proper connectors and was easy to use and set up. It's seems a little pricey, but it saved us from spending $400 on a 24v resmed battery bank, so it's actually a bargain. With the additional adapter cable we bought (usb-c to 24v cigarette lighter) and the battery bank (on sale on Amazon for $69), it cost us $170 instead of $400. I like that math because I saved $230! The whole setup is a good small size and easy to pack with the CPAP, which is why we bought it. If you get one of these and it doesn't work with your battery bank, the problem is probably that your battery does not truly supporting PD 100 output.

This little power adapter an cabling ran my Resmed Airsense 10 with no issues. I was able to injoy a camping trip without having to worry about how I was going to use my cpap without 110v power.
