Review on High-Quality KFD AC Adapter Charger Power Supply Cord (24V/4A) for Resmed S10 370001 CPAP and BiPAP Machines | Compatible with ResMed Air Sense 10 - Ref # 37207 [1 PIN] | Not suitable for Resmed S9 Series (3 Pin) by Kaylon Mackey

Used with ResMed AirSense10 (also called "S10”) CPAP. This adapter was an emergency replacement for my original ResMed adapter (see specifications below). The device suddenly failed without notice. I have since learned that this is a common occurrence and two years of use is a bonus. At 11pm I went to various CPAP online shops and found that most would not ship until the middle of next week; The shipping cost almost matched the high price of the adapter itself! On a whim I went to Revain and found this reasonably priced adapter. I ordered at 11:30pm on Thursday. The adapter arrived on the second delivery day (Saturday!) via Prime. Excellent order processing and delivery times. Packing is acceptable, no damage. I plugged in the adapter and my CPAP worked right away. I've tested it through a ramp, hose, and water heater, and through a "full load" CPAP with no errors. Again, this is a preliminary test so I have no idea of the durability of this PSU. Specifications: There are many devices on the internet that, despite their claims, do not work with S10 CPAP. To ensure that your new power supply works, you need to do it carefully. So here are the characteristics of this device. Your CPAP block should be similar. - SINGLE PIN connector on the back of the CPAP (not three of the many ResMeds) - Input: 100-240VAC, 1.5A - Output: 24VDC, 4A - Supplied with a 120V American style outlet cord supplied which connects to a brick power supply (not shown in picture on Revain). Other Thoughts - The transducer itself is smaller than the original ResMed. This can mean fewer turns and therefore poor life/performance. I don't know exactly but it's worth considering, especially given the low price I paid. So yes. *** I will update my rating if the performance/lifetime is not acceptable.
