The DJI Power SDC to Car Charger Plug Power Cable (12V) is the reverse-direction cable to the car-input cable: it draws power from the SDC port on a DJI Power 1000 or 2000 and delivers it through a standard 12V cigarette-lighter socket, allowing in-vehicle 12V appliances to be powered from the DJI portable power station rather than the vehicle's battery.
