Description
Quick answer: This is the genuine ResMed DC cable (part 24961) that connects a ResMed S9 series device to the ResMed Power Station II (RPSII) external battery. It delivers DC power from the battery to the device so therapy can continue away from mains power — during travel, camping, or a power outage. This cable is specific to the S9 series; other ResMed platforms use different DC cables. Cable only — the battery and device are not included.
What’s included
- 1 × ResMed RPSII DC cable for S9 series (part 24961)
The RPSII battery and the S9 device are not included.
About this cable
The ResMed Power Station II (RPSII) is an external battery that runs a compatible device when mains power isn’t available. The DC cable is the link between the two — it plugs into the RPSII and into the device’s DC input, delivering power directly without an AC adapter.
This particular cable is made for the S9 series. That matters: ResMed uses different DC cables for different device platforms, so an S9 cable will not serve an Air10, Stellar, or other series. Using the genuine matching cable ensures the correct connector, polarity, and current rating for safe operation.

Choosing the right DC cable
ResMed uses different DC cables for different platforms, and they are not interchangeable:
- S9 series → this cable (24961)
- Other ResMed platforms (e.g. Air10, Stellar) → different DC cables
Before ordering, confirm your device series. If you have an Air10 (AirSense 10 / AirCurve 10) or a Stellar, you’ll need a different cable — contact us at (646) 933-0080 with your device model and we’ll make sure you get the right one.
