I just purchased an Omnicharge battery which contains its own inverter and has a regular 120 volt wall plug: www.omnicharge.co
The battery has 20,400 mAh capacity and was primarily designed to power laptops, but supposedly has the technology to recognize the power draw of any device and adjust.

I am hoping someone on this forum has the expertise to know whether the ResMed AirSense 10 Autoset could or could not run on this Omnicharge battery, and if so, how long the battery is likely to last. Thanks

You will have to contact ResMed or your DME to find out how much the electrical draw is on the machine you have. The "tech specs" on the ResMed site don't specify power consumption. In addition, if you use heated humidity, I suspect that the heating element would have a large effect on draw. You will then have to compute how much capacity of your battery divided by draw I guess. Last, the machine has a power supply; probably DC and converts AC to DC to run so I suspect you will have to plug into the 120VAC out on the battery if the device is needed during a power out. I don't know how to make the computation of mAh divided by hourly draw so you will need a tech from the battery company to give you an estimate. Since prices for the fancy battery are not on their website that I could see, I am guessing they are on the pricey side. Let us know what you find out!
