What’s Included

  • 1 90-Watt External Power Supply and Cord to power your S9 Machine

This 90w power supply is the same unit that should have been included originally with your device purchase.

If you are in need of only the cord that plugs in between the wall socket and the power transformer, please order here; Power Cord for Resmed S8 & S9, Machines.

This is a 90 Watt AC ResMed power supply and cannot be used in a DC configuration. The DC compatible cord can be ordered here: DC Converter 24V/90W For S9™ Machines.

Power Supply Change: In 2013 ResMed changed the design of the power supply for the S9 machines. The newer version is smaller and lighter. Both use the same power cord, and either can be used with the S9 machines.

Works Great!

Verified purchase | Dec. 16, 2020 | Verified CPAP.com Customer
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!
