This is a 6 foot long cable that connects a DC-compatible CPAP machine to any 12 Volt battery source. One end attaches to the machine's 12 volt jack and the other plugs into a socket similar to a car's cigarette lighter outlet.

The DC Power Adapter and accessories allow you to operate most Respironics BiPAP systems from a 12 volt DC power source.

Manufactured by ResMed for the S8 and S8 II Series of CPAP machines, this 12-volt DC power cord and external AC-to-DC power converter is designed to allow you to connect your ResMed CPAP or VPAP machine to a 12-volt cigarette lighter power source. Great for those who travel by vehicle often such as campers or long distance truck drivers.

This battery cable adapter is to be used with the ResMed 12-Volt DC Power Cord for S8 Machines. This product will adapt your DC power cord to allow for a direct connection from your ResMed S8 CPAP machine to a 12-volt, 100AH, deep cycle marine battery.
