The ICH-KDUAL-L is a combination of the inch-k-base and two ich-kbp-l battery plates, allowing the user to charge two Sony L-series style batteries simultaneously. With the push of a button, users can switch between high- and low-voltage charge modes, and extra battery plates are available for charging different styles of battery. Plates can even be mixed-and-matched, for charging batteries of different styles and even different manufacturers simultaneously.
