Description
Quick answer: This is the genuine Philips Respironics shielded DC cord system for DreamStation and DreamStation 2 devices (SKU 1120747). It supplies 12 V DC power from a compatible battery or vehicle power source, so therapy can continue away from mains electricity — for camping, RV travel, road trips, or as backup during a power outage. The shielded construction helps reduce electrical interference. Battery and device are not included.

About this cord system
Running a CPAP away from a wall outlet requires a 12 V DC power source and the correct cord to connect it to the device. This is that cord for the DreamStation platform — covering both the original DreamStation and the DreamStation 2, which is the practical advantage of this version over the single-device cord.
The shielded design matters more than it sounds. DC power drawn from a vehicle or battery can carry electrical noise, and shielding helps prevent that interference from reaching the device — which is why the manufacturer specifies a shielded cord rather than a generic one. Using the genuine part also ensures the correct connector, polarity, and current rating.
Note that a DC cord is not the same as a battery adapter cable: some external battery setups require an additional adapter between the battery and this cord. Confirm what your specific battery requires before ordering.
