This replacement ResMed S9 Power Supply is available for purchase in the event that the original power supply for your ResMed S9 CPAP Machine is damaged or broken. The power cord which plugs into the wall outlet is included with this product, as well as the power adapter, or power brick.
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.
