GoodKnight 420 Series 12Volt DC Cord Overview

This cable is used with the Puritan Bennett 420 Series CPAP Machines. The cord allows you to connect to a socket similar to a car's cigarette lighter outlet. One end connects to the back of the CPAP and the other end fits into a 12v DC power point.

This cord is compatible with the following machines:

  • 420G
  • 420S
  • 420E


This cable will not work with the GoodKnight 425 or 425 ST. The 12 volt jack on the 425 Bilevel is not the same size as the 420 series CPAP machines. To connect a 425 BiLevel to a socket similar to a car's cigarette lighter outlet, use the 12 Volt DC Power Cord.
