This DC Coupler DR-E6 is compatible with select Canon digital cameras. It fits inside the camera's battery compartment and has an attached 7.5' DC cord. This cord plugs into the AC-E6 AC adapter accessory.
Works flawlessly with my Canon EOS R6 and AC-E6 adapter. The coupler fits securely in the battery compartment, and the 7.5' cord gives me plenty of room for studio shooting. Long sessions are no problem—reliable, steady power every time. 5 stars!
