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

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.

How many watts
Hi Fred,
The ResMed DC/DC Converter for the AirSense 11 and AirCurve 11 is designed to power your machine from a 12V or 24V DC source and supports the full power requirements of the device, including humidification and heated tubing.
Power consumption varies depending on your therapy settings and whether you're using the humidifier and heated tube. Under typical use, the AirSense 11 can draw anywhere from approximately 10W to over 65W.
If you're planning to use a battery, let us know which battery model you're considering and we'd be happy to help estimate runtime.

how long is the cord, i.e., how far can it be from the car lighter socket to the 24 V AirSense/AirCurve power input
Hi there 😊
The ResMed DC/DC Converter for AirSense AirCurve 11 cord is approximately 9 to 10 feet (around 2.7 to 3 meters) in total length.
That usually gives you enough reach from the car’s cigarette lighter socket to your machine, even if it’s on a seat or nearby surface.
Let us know if you need a longer setup!

Follow up question. I am trying to find out the power consumption with this device. You said that you can’t tell me the consumption since it depends on the settings of the device. Please tell me what the power consumption would be at the minimum and maximum settings for the device. Otherwise I would have to purchase the device and measure power consumption with an ammeter. These specifications should be available online
Hi there 😊
For the ResMed DC/DC Converter for AirSense AirCurve 11, power draw depends on the CPAP device settings, but here are realistic ranges based on ResMed specs:
- Minimum (no humidifier, low pressure): ~10 to 30 watts
- Typical use: ~30 to 60 watts
- Maximum (high pressure + humidifier + heated tubing): up to ~90 watts
The converter itself is very efficient, so it doesn’t add much extra load beyond the machine.
If you’re planning for battery or car use, sizing for ~60 to 90W will keep you on the safe side.

Your answers to questions about specs for this power supply are inaccurate. Your answer talks about 110 V AC input when the input is either 12 or 24 V DC. I really need to know the 12V Dc current draw to see what it takes to power my resmed air 11 with this power supply. Please answer this question and not something unrelated as you’ve done twice in the past list of questions.
The DC/DC converter can accept an input of either 12V or 24V and gives an output at 24V which is what is required for the AirSense 11 machine. The current draw of the machine will vary drastically depending on the pressure settings and humidity settings of the machine. If this does not answer your question, please feel free to call us at 866-936-3754 or to call ResMed directly at 1-800-424-0737

Follow up on a question. So with this cigarette plug adapter for the as11, is it just made to hooked up in a car socket and not just into a 12 volt battery. It seems to me it could considering how the plug is made. The answer to the other question made me to believe I could use the 12 volt adapter to plug into a 2 volt battery and only a car.
Yes, the adapter is just for the cigarette plug adapter.
