12 Volt DC Power Cord (Connects CPAP to Cigarette Lighter Socket)

The 12 Volt DC Power Cord (Connects CPAP to Cigarette Lighter Socket) 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.

IMPORTANT NOTE: This cord is NOT compatible with the PR 60 Series line of machines. Please refer to the Important Tips and Video & FAQ tabs of this page for steps to identify the differences between 50 and 60 Series machines.

This 12 Volt DC Power Cord is compatible with the following units:

• All Respironics M Series Machines

• All 50 Series PR System One Machines EXCEPT 60 Series Models

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

• Respironics Synchrony Machines

• All Sandman Series Machines

• GoodKnight 425/425 ST BiPAP Machines

This cord CANNOT be used with PR System One 60 Series 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 the Puritan Bennett GoodKnight 420 series of CPAP machines. You will need to purchase the GoodKnight 420 Series 12volt DC Power Cord.

Vehicle Safety Tips

These vehicle safety tips are written according to statements from the manufacturer.

• When the device is not in use, the Shielded DC Cord should not be plugged into the vehicle.
• When DC power is being drawn from a vehicle battery, the manufacturer suggests only using when the vehicle's engine is turned off. Please observe battery capacity to avoid draining the vehicle's battery.
• The alternator, which runs when the vehicle is in use, can cause voltage spikes that will potentially damage the DC cord.
• The 12 volt is intended to be used with systems that are either "positive hot" or "negative ground" only. If these details are unknown, speak with the manufacturer of the vehicle.

How to Tell the Difference Between a 60 Series and 50 Series Machine

1. Color
   • PR System One REMStar 60 Series Machines and Heated Humidifiers are charcoal gray with metallic silver side and instrument panels.
   • Original 50 Series PR System One units are dark gray with ivory colored side and instrument panels.
2. Branding
   • The PR System One REMStar 60 Series Machines have the words "System One" in raised or embossed letters stamped in silver on both the machine and humidifier.
   • Original 50 Series PR System One units do not have raised lettering, the branding information is painted onto the unit.
3. Machine and Humidifier Connections
   • PR System One REMStar 60 SeriesMachines and Heated Humidifiers have a 6 pin connection between the machine and humidifier.
   • Original 50 Series PR System One Units have a 4 pin connection between the machine and humidifier
   • PR System One REMStar 60 Series Machines and Heated Humidifiers have a mechanical connection between the machine and humidifier
   • Original 50 Series PR System One Units have 2 tabs on the humidifier that fit into 2 slots on the machine.
4. Model Number Reference
   • PR System One REMStar 60 Series Machines label identification example: the label on the bottom of the PR System One REMStar 60 Series Auto CPAP lists: "REMStar Auto"; "REF" of 560P; and Serial Number identified by "SN". The number 560 references the part number of the machine.
   • Original 50 Series PR System One Machines label identification on the bottom of other versions of System One machines lists: Machine name; "REF" that does not have the number "6" in the second position from the left; and Serial Number identified by "SN". For example the label on the bottom of a PR System One REMstar Auto CPAP Machine with A-Flex lists "REMStar Auto" and "REF" of 550P. The number 550 references the part number of the machine.

REGARDING HEATED HUMIDIFIERS:

Please Note:

When using a heated humidifier with a CPAP, the fuse in the Philips Respironics DC cable MUST be changed out from the 3AMP to 7AMP. If this is not done, the 3AMP fuse will blow out and the DC cable will no longer function.

Word of Caution to RESmed S8 and S8 II Machine Users

YOU MUST USE THE DC12 Converter for S8 Machines in conjunction with any battery source, when using an S8 or S8 II machine. Failure to do so can result in damage to your CPAP.

ResMed VPAP Auto 25 and VPAP ST

The ResMed VPAP Auto 25 and VPAP ST use a different cord, DC-24 Converter For ResMed. Refer to the Respironics Battery Kit for ResMed VPAP Auto 25, VPAP Malibu & VPAP ST Machines for a battery kit for these machines.
