  • Buy to Replace Battery or Keep on Hand for a Convenient Power Backup
  • Lightweight Battery Pack for Additional Mobility
  • Easily Use with Compatible ResMed Devices

Twice the Batteries Offer Double the Run Time

The ResMed Power Station II (RPS II) allows the user to use two batteries at the same time to double the battery run time, which is extremely useful when using the external battery as backup power during an unexpected mains power failure, or if you need a portable CPAP battery for camping. The function automatically switches between the two batteries as needed.

To use the RPS II battery pack with an S9 machine, AirSense 10 CPAP machine, or AirCurve 10 CPAP or VPAP machine, you'll need a separate converter not included with this product. 

The equivalent lithium content of a single RPS II lithium-ion battery meets requirements for safe travel as set by the IATA.

Please note: The RPS II has a voltage output selector on the back panel of the unit which can be used to change from 24v to 26v power. All S9 or AirSense™/AirCurve™ 10 CPAP and VPAP devices require 24v with and without the use of a humidifier.

To Power an S9 or AirSense™/AirCurve™ 10 Machine on the ResMed Power Station:

  • Select "24v" output on the back panel of the ResMed Power Station II
  • Connect the S9 Series DC Cable for ResMed Power Station (RPS) II or AirSense™/AirCurve™ 10 Series DC Cable for ResMed Power Station (RPS) II to the ResMed Power Station
  • Remove the cap from the other end of the S9 or the AirSense™/AirCurve™ 10 Series DC Cable for ResMed Power Station
  • Connect the uncapped end of the S9 or the AirSense™/AirCurve™ 10 Series DC Cable for ResMed Power Station to the S9 or AirSense™/AirCurve™ 10 machine in the port, where the power cord is normally connected to the CPAP device.
  • Turn on the ResMed Power Station
  • Turn the S9 or AirSense™/AirCurve™ 10 machine on as normal

The ResMed Power Supply Unit (PSU) Adapter for both the S9 and the AirSense™ 10/AirCurve™ 10 machines are NOT used to operate the RPS II. During use, the S9 or AirSense™/AirCurve™ 10 Series DC Cable for ResMed Power Station (RPS) II connects directly between the RPS II and the S9 or AirSense™/AirCurve™ 10 machines.

The S9 Series DC Cable for ResMed Power Station (RPS) II and the AirSense™ 10 and AirCurve™ 10 Series DC Cable for ResMed Power Station (RPS) II are for use ONLY with the ResMed Power Station II and are not compatible with other DC sources.

To Charge the ResMed Power Station:

  • Connect the Power Supply Unit (PSU) Adapter for ResMed Power Station (RPS) II to the ResMed Power Station
  • Connect the External Power 90 Watt Supply for ResMed S9 Series Machines or the External Power 90 Watt Supply for ResMed AirSense™ 10/AirCurve™ 10 Series Machines to the PSU Adapter
  • Plug the S9 or the AirSense™ 10/AirCurve™ 10 Power Supply into an AC wall outlet
  • The "charging" light will show until the battery is fully charged
  • If unused, the battery MUST be recharged every three (3) months

Depending on the machine being used, the Power Supply Unit (PSU) Adapter for S9 Machines for ResMed Power Station (RPS) II or the Power Supply Unit (PSU) Adapter for AirSense™ 10 and AirCurve™ 10 Machines for ResMed Power Station (RPS) II are required to charge the RPS II. The PSU connects the RPS II to both the S9 External Power Supply and the AirSense™ 10/AirCurve™ 10 Power Supply.

The S9 Power Supply Unit and the AirSense™ 10/AirCurve™ 10 Power Supply Unit that come standard with all S9 or AirSense™ 10/AirCurve™ 10 machines are used to charge the ResMed Power Station II. The S9 and AirSense™ 10/AirCurve™ 10 power supply are not included with the battery.

The manufacturer warranty for the ResMed Power Station II is 6 months.

HIGH Quality Battery

Verified purchase | Aug. 26, 2016 | Verified CPAP.com Customer
The ResMed Power Station II Battery is a high quality long lasting battery. I bought the ResMed Power Station II KIT, which comes with one battery, and then bought this second battery as a back up for the kit's battery. I connected this battery and the KIT together in "series" to provide uninterrupted back up power for my CPAP machine. The set up is easy. The unit is compact and well designed. I highly recommend it!

Good backup

Verified purchase | Aug. 19, 2014 | Verified CPAP.com Customer
tested it with my Resdmed S9 Autoset and lasted 2 nights with a setting of 11 to 23 on the cpap (auto). With the humidifier only 4 hrs. It is a good backup to use without the humidifier in case of house power loss. Reviewed TSA's requirement for carryon baggage and it seems to meet their 100 W-Hr max limit for Lithium-Ion battery, however I have not actually tested it by taking it through a TSA check point. Most airlines adhere to this limit, but may vary with each airline.

Incredibly Small

Verified purchase | Jan. 11, 2013 | Verified CPAP.com Customer
Powered my S9 at a pressure setting of 15 for 7.5 hours before the low power incator went off. I would rather trade off size for more capacity, but the battery is incredibly small. I could slide it into my back jean pocket.
