The DC Power Cord for IntelliPAP 2 CPAP Machines by DeVilbiss is a 12V DC cord that connects an IntelliPAP 2 CPAP machine to a cigarette-lighter style DC outlet. This cord is compatible with the IntelliPAP 2 machines only and will not work with any other machines.
The DC cord will power both the IntelliPAP 2 machine and humidifier. Please note that use of the heated humidifier from a DC power source will dramatically reduce the run time of the power source. The humidifier can be turned to 0 to be used as a passover humidifier to reduce power draw.
