ResMed | DC/DC Converter | AirSense / AirCurve 11

Work great for camping. Easy to use and compact. Better than using an inverter because it's more energy efficient that inverter with the home power supply. Less drain on the RV deep cycle battery.

Works as expected. I have read that the cheaper non Resmed brand adapters don’t work properly or reliably so I went with the name brand. I use it with the 12v port on an Anker solix dc300 battery pack without issue and the Anker battery can be used as a UPS if I also charge it at the same time it is powering my Resmed s11. The s11 draws between 20-30 watts while in use with auto humidity and heating, and 5 watts on standby according to the battery. Runtime is about 10-11 hours with my setup if running completely off battery.

This adapter works perfectly with my backup battery and gives several more hours of use, when turning climate control off, over just plugging the regular AC adapter into the ac port of the battery. Very happy.

Okay,not bad .But need filters so no mold or dirt goes down your lungs
