ResMed Power Station II (RPS II) -- Charge Your S9 Machine

https://www.respshop.com/power-solutions/resmed-power-station-with-cable-pack-p-372.html The ResMed Power Station II -- with its S9 DC Cable Pack -- is a charging device designed to power your ResMed S9 Series CPAP or VPAP. The RPS II is also compatible with a few models from the S8 series of ResMed machines as well, though it will not function with the new line of AirSense devices. The RPS II charges in just four hours, and a full charge can easily power your machine for a full night of therapy. This is ideal for patients who are using their machine on the road, as they can take their ResMed to a hotel or to the campground without sacrificing a night of quality sleep. The device has an easily readable interface, and you can see how far along the charge is right on the battery itself. Additionally, hooking your machine up to the power station is a breeze, requiring you just to connect a simple cable. Included with the RPS II is a travel bag, a power supply unit adapter, and (optional) a S9 series DC cable, as well as the lithium ion battery.
