This Coupler Kit is designed exclusively for use with ResMed Power Station (RPS) II Battery Packs. It is used to connect two RPS II Batteries in series in order to double your CPAP/BiLevel run time away from fixed power sources. In addition it enables both batteries to charge automatically without the need for plugging and unplugging.
Usage Information: The Coupler Kit includes the coupler cable box as shown as well as a velcro strap which may be used to hold the two RPS II batteries together for convenience when in use.
This was the cheapest adapter that i was able to find with free shipping to. The adapter was brand new and worked perfectly. The finding, paying for and shipping was fast and easy. Written by scott_w_anderson2000, 2017-11-03
