The DC Cable plugs into the same port, on the back of AirSense & AirCurve Series CPAP/BiLevel machines, as the standard AC Power Supply and will allow you to power your CPAP/BiLevel machine directly from the RPS II Battery Pack.

Usage Information: Before using this cable remove the protective end cap from the machine end of the cable which is used for packaging and transport. This cord will not work with standard 12V cigarette lighter power sockets. For cigarette lighter DC power sockets use ResMed's AirSense & AirCurve DC Power Cord (Part 37297) sold elsewhere on this site.
