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

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. more...

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. more...

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. more...

Charging cord is what was pictured and I was looking for. Have not had the chance to use yet.

The people at CPAP.com were friendly and very helpful helping me select the correct DC Converter and the product works... great! more...

Mobility is what I needed

Haven’t used this just yet, bought to use when we go camping. Looks as though it’s going to work for... what we need it for. Had one for a different machine and it worked fine. more...

Excellent product worth every penny

No problems--works fine

The product was exactly what I needed and performed to my satisfaction. The best part of the experience was dealing... with your sales representative, who was extremely knowledgeable and professional and was able to determine what item I needed. Pleasant experience and happy customer more...
