ResMed RPS II Battery Coupler Kit (Power Station II)

Description

Quick answer: This is the genuine ResMed battery coupler kit for the Power Station II (RPS II) (part 24964) — it connects two RPS II battery packs together so you can double the battery run-time of a ResMed CPAP/BiLevel machine away from mains power, or charge two batteries at once without swapping cables. It includes the coupler cable and a Velcro strap (to hold the two batteries together). For use with RPS II batteries powering S9, AirSense 10, and AirCurve 10 series machines. Batteries and device not included.

What’s included

• 1 × RPS II battery coupler (cable/connector box)
• 1 × Velcro strap (to hold the two batteries together)

RPS II battery packs, CPAP/BiLevel machine, DC cable, and PSU adapter not included.

About this part

The ResMed Power Station II (RPS II) is ResMed’s external lithium-ion battery for running CPAP/BiLevel therapy away from mains power (camping, travel, RVs, power outages). A single RPS II gives you one battery’s worth of run-time — and this coupler kit is what lets you use two:

• Double the run-time — connect two RPS II batteries so your machine runs roughly twice as long on battery power between charges.
• Smart switching — the coupler automatically draws from the battery with the most charge for optimal performance (one serves as primary, the other as reserve).
• Charge two at once — it also lets both RPS II packs charge together automatically, without plugging and unplugging each one.
• Velcro strap included — holds the two batteries neatly stacked together.

Compatibility: the coupler works with RPS II battery packs used to power ResMed S9, AirSense 10, and AirCurve 10 series CPAP/BiLevel machines. You still need the correct DC output cable and, for charging, the correct PSU adapter for your device (e.g. the Air10 DC cable 37343 and Air10 PSU adapter 37342) — those are separate.

Note: the Power Station II is designed for use with ResMed-branded devices only.
