ResMed has discontinued this item. You can still use your S8 CPAP/BiLevel machine from a DC Power Source with the Tripp Lite Power Inverter available elsewhere on this site.
ResMed's DC-12 Converter allows you to operate S8 CPAP/BiLevel machines from 12 volt or 24 volt DC power sources like the "cigarette" style sockets found in most cars, boats and other vehicles. This is the only cord that should be used with these ResMed systems.
Compatibility Information: This cord is compatible with all S8 Escape, S8 Escape II, S8 Elite, S8 Elite II, S8 AutoSet Vantage, S8 AutoSet II, and VPAP Auto machines. This cord will not work with the S8 Compact; for the S8 Compact use the ResMed approved PowerVerter 150 available elsewhere on this site. For the VPAP S, VPAP ST, VPAP Auto 25 use cord part number 26932.
