About this product

Yes, this is the correct replacement power supply if you run a ResMed S9 series CPAP machine: it is the 90 Watt external AC power supply that shipped as standard with the S9 system, and it comes with the AC power cord. It plugs your machine into a standard wall outlet, and this power supply is FSA/HSA eligible.

The power supply accepts universal input, 100 to 240V at 50 to 60Hz, so it works on different mains voltages when you travel. In 2013 ResMed updated the S9 power supply to a smaller, lighter design. Both the older and newer versions use the same power cord, and either one works with your S9 machine.

This is a wall power supply, not a battery. It measures about 6.5 x 2.5 x 1.5 inches and includes the 90 Watt power supply unit plus the power cord. Browse our CPAP machines or our full power solutions collection for more ways to keep your equipment powered.
