DC Converter 24V 90W For AirStart™ 10, AirSense™ 10, and AirCurve™ 10 Machines

I purchased this because it was recommended with the Medistrom Pilot-24™ Lite Battery and Backup Power Supply because the battery does not come with a power supply. When I received the battery and these power supplies, it was clear that they were not necessary. All you need is the power supply you use for your cpap. Not only do I feel mislead that I needed this power supply, cpap.com won’t return it because I’ve opened the package! CPAP.com’s return policy does not care about their consumers and does not seem to want customer loyalty.

The socket connection poorly seats, wiggles 1/8” in a shallow socket with a male connector with too much force in the spring contributing to the 98% tendency to disconnect power. Tried taping to secure but the connection was too sensitive for that operation. Want to run direct off a battery.

I purchased this converter to use while rustic camping where AC electric power is not available. I utilize the DC converter (item no. 37297) with a deep cycle RV/Marine Battery and got 30 hours of run time over a period of four days and the battery still had power. These DC converters are amazing for power outages or when camping remotely.

I use this with a RockPals portable battery back for when power goes out. At first I tried RockPals DC-DC converter, but it couldn't handle the power surge at startup. It immediately shut down. The Resmed converter works great. I've used it several times to confirm that it does work and once when power was out for a day. Since it's for emergencies, I use it with the humidifier and heated tube turned off and I get 3 nights with a few hours left.

I used this with an RV battery, and everything worked great. This let me go on a campout without having to set up my tent as far away as possible so I wouldn't bother anyone.

I'm not impressed with this at all. The connection between the lighter plugs is very loose. If it moves even a little, the power cuts off. I'll probably have to tape it in there or find some other solution to make the connection more sturdy. They should have just put the alligator clips directly on the power supply rather than a lighter plug. I hope this doesn't damage my machine since the entire reason I got it was to use a battery during thunderstorms in order to protect my machine from lightning strike.

I am very unhappy with this product gave the person the serial number for my machine to oder the adapter and was told which one it was for and was wrong one.

I purchased a Tenergy 300 Watt hour LION Battery Supply for Power Outages for my CPAP (Aircurve 10 ASV). First I used it in the AC Inverter mode and it worked well but used a lot of power and kept running the cooling fan every half hour or so. It ran overnight about 8 hours and still had charge left perhaps for another night. Then I decided to get the DC to DC Inverter supply for the Air Sense/Aircurve 10 for better efficiency. I used it the first night and it ran very quietly drawing about 15 to 20 Watts with Humidifier set at 5. I was impressed the fan did not run all night. At that wattage, I calculated it would run about 15 plus hours which I figure to last two nights easily.

Received a great product don’t want to go through a week of no sleep cause no power again

It has worked well but the battery we bought had fake information as too how many hours it would last. Said five of days and only lasted for one night. You did well they are scamming. Thanks for your product it is as described.

I used it in conjunction with a battery to run my AirSense 10 CPAP machine. It worked perfectly, my only slight critique is that it is very large and heavy, perhaps unavoidable to do its job, but less convenient for travel.
