Ideal for use during really long shoots, the LPE19/DRE19 Battery Coupler for Canon from Bescor is designed for use with the Canon EOS-1D X Mark II DSLR and Canon EOS-1D X Mark III DSLR. The coupler is a plastic insert that is slid into the camera's battery compartment and when connected to a separately-purchased (and required) AC plug with a male barrel connector, "tricks" it into running on household AC power.
