The LP-E17 DC Coupler (Dummy Battery): Shaped exactly like a standard LP-E17 battery, it slides directly into your camera's battery compartment. The attached power cable feeds out through the tiny rubber pass-through slot on your camera's battery door (the door must be fully closed for the camera to turn on).
The Integrated Power Plate: The cable connects directly to a rigid mounting plate designed to hold any standard NP-F series battery (NP-F970, NP-F750, or NP-F550).
Voltage Regulation: A standard NP-F battery outputs around 7.4V to 8.4V. The adapter plate features built-in electronic step-down converters that automatically regulate this energy to the stable 7.4V–8.0V your Canon camera requires, ensuring safe operation with zero risk of frying your camera's circuits.
