Airline Friendly CPAP Therapy, thanks to the Resmed Power Station II

The Resmed Power Station II is a 97w/hr Lithium Ion rechargeable battery, designed to power all Resmed S9 CPAP machines. Fully loaded, it's only 30cm x 20cm x 10cm deep and weighs just over 2 Kgs.

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. Use the PowerStation to run your S9 machine and you don't need to fly First Class just to get access to a power point.

No other adaptors are required, just charge the Power Station II using your S9 Power pack, then plug and play (or sleep). The Power Station II comes ready to use, in a nifty travel bag. Power cord, and adaptor is included, in their own storage pockets. There is even a space for an optional second battery to double the usage time.

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.
