Works Great!

No issues at all. Exactly like the one I was replacing. Glad for the photo of the plug so I could confirm it had the right kind of connector. No Rx confirmation needed, and it arrived right on time.

Bought for a battery

Verified purchase | Sep. 05, 2020 | Verified CPAP.com Customer
My resmed S9 battery takes this power supply to charge, and since I’m passing my old machine on I need the power supply to recharge the battery that I’m keeping. Tried it and works well. At this price you should have a spare in case of power spikes. How many computer power supply’s have you bought over the years? Think about that!
