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 12v jack that connects to the machine will fit several of our most popular CPAPs.

This cord is compatible with the following units:

• All Respironics M Series Machines

• Respironics REMstar CPAP/APAP Machines (No REMstar BiPAP units)

• Respironics Synchrony Machines

• All Sandman Series Machines

• All IntelliPAP Series Machines

• GoodKnight 425/425 ST BiPAP Machines

The Synchrony BiPAP and BiPAP ST use this cord, but the fuse within the cord's connector must be changed to use the 7amp fuse supplied within the package.

If you wish to run directly off the battery terminals, you will need this cable and the 12 volt Battery Adapter Cable, which has battery clamps on one end.

This cable cannot be used with the Respironics REMStar BiPAP Auto, BiPAP Auto ST, BiPAP Pro 2 or the BiPAP Plus. You will need to purchase the RP-DC Power Adapter Kit.

This cable cannot be used with ResMed S8 and S8 II machines. You will need to purchase the DC-12 Converter For S8 Machines.

This cable cannot be used with the Puritan Bennett GoodKnight 420 series of CPAP machines. You will need to purchase the GoodKnight 420 Series 12volt DC Power Cord.
