    This device is designed (I guess) to supply enough power to run the 10 series with the humidifier on a 12 or 24 v battery. Why they made the CPAP machine 24v in the first place is beyond me. I would say a high percentage of the US users are going to being using the CPAP in an RV or camping and to use the CPAP on battery would take a multi-battery bank. For CPAP only (and the 10 series can easily be set to "humidifier OFF" ) Resmed told me the 12v amp draw was 1.6. I also needed to know the to properly size additional wiring. No one is going to want the battery in their tent or RV so the battery clip and lighter socket cord at least in my case, had to be extended with the use of small connectors so the socket was accessible inside the RV without having to cut massive holes in compartments to feed the socket or clips thru.

  • cpapXchange made it right

    When I ordered a DC power converter for my AirSense 10, they accidentally shipped it ground which wouldn't arrive in time for my camping trip. They shipped another unit out overnight. They provided me a return label to send the one they sent via ground. So, they corrected the error and did a great job of getting the converter in time. Would deal with again...

  • Efficient converted, works perfectly.

    Device is far more efficient than a DC->AC converter. So far it has worked perfectly (10 days).

  • The converter works great

    Took it camping and had no problems. Did not use the heater tube though to conserve power. Make sure you have a deep cell rv /marine battery

  • Worked for a week and quit

    I paid nearly $100 for a power cable that quit after a week of use. Don’t waste your money.

  • It works, but was too expensive

    I got a new CPAP, which I love. The cable for the battery I have for camping would not work with the new machine. This is the only 1 I could find. I have to have it, but I resent that it cost $$$. Of course, it was a lot cheaper than cost of a new ResMed battery pack.

  • Portable Power for Resmed S 10 machines

    I used this on a RV trip to the woods. I used my 12 volt 100Amh deep cycle battery and ran my Resmed S10 AirCurve Auto Bipap machine (without humidifier) for 7 hours a night, and four days without recharging. The battery still had ample power left too. This works great and easy to use. Thank you.

  • Great for Camping

    I bought this and used it with a marine deep cycle battery while camping. It worked great. At a pressure of 10 I was able to sleep for 3 nights for over 8 hours each night. I sure am glad that I purchased it and was able to go camping and spend time with my family and not worry about my power supply.

  • DC Converter 24V 90W for ResMed Air Sense 10

    Great description and product, excellent communication, fast shipping, and works perfectly...thank you!

    I hooked it up to a 55ah Gel-style RV battery. This converter is extremely well designed. You get connectors to the battery that have a built in on/off switch so you don't have to disconnect the battery. Extremely well built and I got 17 hours of sleep time at auto 12-20 pressure. The battery still had an undeterminate amount of power I removed the Cpap. Well worth the price.

  • Ready for a power outage.

    Perfect for a power outage or camping. Tried it out by having a nap in my car. Works like a charm.

  • Does what it says on the tin

    I used a dc cord with my AirSense Auto several times this summer. Yes, it's 9 feet long and you shouldn't use your humidifier with it. That's pretty much true of all dc cords. It does exactly what it's supposed to do.

  • Power Converter for AirSense 10

    Bought this to use tent camping. First off, car needs to be within 9 feet of where you sleep. This is definitely NOT long enough. I bought a new car battery prior to leaving. First night, I used as normal with the humidifier. My machine quit working and my battery went dead before I woke up. Second and third night, I turned off humidifier and the battery lasted through the night. I didn't trust that it would go more than one night so I had to drive the car to recharge the battery every day which was a total hassle! On night four I decided to try the humidifier again. Battery went dead. On the fifth night I turned the humidifier off and the battery went dead again. The last night.......we used my friends truck with a heavy duty battery and it was fine. To sum it up......don't waste your $100!!!
