The ResMed Power Station II (RPS II) is an all-in-one external battery that can be used to power ResMed devices when mains power is not available. The battery gives you approximately 10-14 hours of use, when the humidifier is not attached. It's very lightweight and easy to travel with.


Please be advised this battery will only operate when used in conjunction with the appropriate (AirSense 10 or S9) DC Cable.  Therefore this battery should only be purchased on its own if you already have the appropriate DC Cable.
