The RPS II (The ResMed Power Station II) is an all in one external battery that enables operation of compatible ResMed machines where mains power is not available.

This battery is ideal for travel, but it also provides back-up power in case of an unexpected mains power failure.

This long-lasting lithium-ion battery can be used with the S9 and Airsense 10 series CPAP machines.

Battery running time estimates are hard to provide as consumption is dependent on the device model, settings, leaks, battery quality and age, unique breathing patterns of the patient, environmental conditions and external accessories such as a humidifier and heated tubing.

However, when fully charged, the external battery should provide up to 13 hours of run time (when the CPAP device is set to run without humidifier or heating tube)

If you will be highly dependent on the battery, we recommend that your purchase additional batteries for convenience and peace of mind.


Another feature is the Battery Coupler (sold separately) which connects two RPS II batteries in a series.  It will automatically switch to the other battery when required.


Please Note: When you are purchasing the RPS II battery power bank, that you will also need a DC cable and a PSU adaptor if you are intended to use it on an S9 or Airsense 10 CPAP device
