The ResMed Power Station II is a 97w/hr Lithium Ion rechargeable battery, designed to power all ResMed S9 & AirSense 10 CPAP machines. Fully loaded, it's only 30cm x 20cm x 10cm deep and weighs just over 2 Kgs. There is even a space for an optional second battery to double the usage time.
Lithium Ion batteries are accepted by airlines to power medical devices during flight. (Of course, you must check with your airline well before you fly, in case they need more information or forms filled out by you.) The PowerStation has a 97watt/hr capacity, which is under the 100 watt/hr maximum allowed without approval for airline flight.
Re- charge the Power Station II using your S9 or AirSense Power pack, then plug and play (or sleep). The Power Station II comes almost ready to use if you have an S9 machine (you need a DC Cable), but you need to get the correct adapter and cable if you have an AirSense 10 machine.
Expect to get 8 hours of CPAP time from a fully charged battery, BUT a lot less if you turn on your humidifier - we suggest you use it as a flow-over humidifier by turning it to a setting of 0 while using the Power Station II. By doing this you still get some humidification, but about 4 times the battery charge life. Cannot be sold outside Australia.
Additional Parts Required
S9 Machines - you need to also purchase #24961 DC Cable
AirSense 10 Machines - you need to also purchase #37343 DC Cable and #37342 PSU Adapter
Please note: The ResMed Power Station II is NOT compatible with the ResMed AirMini.
Q: How long does the ResMed PowerStation take to charge up? A: Less than 4 hours for a complete recharge.
Q: Can I use my ResMed S8 Autoscore with the ResMed PowerStation II? A: No. ResMed only has a connection cable for the S9 series of machines.
Q: I have a auto set S9. How many hours do I get on one charge with the ResMed PowerStation? A: Approx 8 hours using the machine only (humidifier off or unattached)
Q : Are you able to recharge the ResMed Power Station via a 12 volt cigarette lighter? A: Yes you can use the 12v converter or an inverter to recharge, it will probably take a lot longer to charge though
Q: I have an AirSense 10 and want to go camping without mains power to recharge the battery. If I have a 12volt adaptor I understand I can use the car battery - but would this drain the battery to recharge? A: You can expect to receive up to 8 hours using the converter, but a lot less if you are using the humidifier. In my experience, yes, it will drain the car battery. I would suggest a deep cycle marine battery as an alternative, then you can use the alligator clips and charge your phone etc. without using the car battery.
