The Hawk-Woods Dummy Battery Adapter for Canon EOS 1D attaches to a cable-mounted 2-Pin powerCON (D-Tap) and allows the user to power an EOS camera from an external broadcast battery source.
Prominently used in HD recording and time-lapse photography, these cameras can now be powered from V-mount or other types of battery. The advantages of using a single high capacity battery over dozens of standard Canon batteries are obvious. The DC-1D1 just needs to be plugged into a D-Tap power socket on a suitable battery fitting. This adaptor has an inline 12V regulator making it compatible with any output distributing 10-20V.
