KFD12V 24V Car Charger Vehicle Power Supply 90W for Resmed S10 Series ResMed Airsense 10 Air Sense S10 AirCurve 10 37297 Series CPAP BiPAP Machines,Resmed S10 370001;300W/500W Portable Power Station

Is 12 V adapter works perfect with my CPAP. It pulls about 5 W of power with my heater turned off of my CPAP. I have a Jackee Explorer 2000 so I could get well over a month of usage if if all I ran on, it was my CPAP. It is perfect for what I needed and would highly recommend if anyone needs to run their CPAP with a similar battery bank.

As a CPAP user for 20 years living in South Florida for the last 10 years, I went thru Hurricane Irma with no power and no CPAP. Sleeping was impossible and I resolved to never get stuck in that situation again.That said, I started with a large 100+Ah AGM battery, a float charger to keep it fully charged, and an inverter to create 110 volt for my CPAP power adapter. I thought I was good until I realized that I would be taking 12 volt and converting it to 110 volt so my CPAP adapter could convert it to 24 volt to power my ResMed Airsense 10. This was inefficient at best since each power conversion is never 100% efficient.Doing a little research recently I discovered ResMed also had a car adapter available to take 12 volt directly to 24 volt. Perfect... until I saw the price! Over $100 for this little adapter. Seriously, folks??!!?!?That brought me here to Amazon where I found this KFD adapter. The price was certainly reasonable and it works great! When it arrived, I disconnected my float charger and hooked up this KFD adapter to my CPAP and started testing to see how much CPAP time I can get out of my AGM battery.So far, without the heated air tube and humidifier options (which I never use here in South Florida anyway) I have gotten 8 nights of CPAP use and both the adapter and battery are still going strong!Bottom line, this car charger works perfectly with my ResMed Airsense 10 and while my KFD adapter may never see the inside of a car or travel much, I will have it at the ready and tucked away with my other hurricane supplies knowing that I am in good shape in case of disaster.If you use any of the listed ResMed models, this is not a WANT, you NEED this! And I might also recommend a AGM battery and a float charger to keep it charged if you live in an area which is prone to lengthy power outages or do any kind of rustic camping.Even a smaller, cheaper 35Ah AGM battery (slightly larger than a motorcycle battery) would provide enough power for at least a weekend of CPAP use without AC power.

I used a Bluetti EB70S portable power station when I go camping. If I plus in my CPAP maching to this power station, I get a little over 2 nights of usage. However, this adapter lets me plug in to the same power station and get 11 nights of usage. This is a a major improvement and I wanted to post this review for anyone wondering whether buying this is worth it for the CPAP machine.

The media could not be loaded. I use this with my ResMed Airsense 10 hooked to a Bluetti AC200P. I was just using the 120v adapter but this 24 volt converter sips the power compared to the 120v hookup. I looked for an OEM one but could not find one. This one works really well and is very compact. This would also be a good solution for CPAP power in a vehicle.

I've used this with my AirSense 10 CPAP for handful of years now, and it's perfect. It reduces the drain on my battery backup (DC to DC is more efficient than DC to AC to DC). Sometimes you have to wiggle/spin/reinsert the plug on the "car adapter" side (I usually only need to do this once or twice a year) which is typical of plugs of this type, so that's going to be the case for ANY adapters like this.

It does work.

Needed an adapter to power my CPAP from a battery during a power outage and this plugged right in and worked great at a fraction of the cost of the name brand adapter.

Bought this for my husband's C-Pap when boondocking. When he used the 110 outlet on our jackery 500 he got 1 night. Using this he was able to get 5 nights!
