FXLION PL-3680Q-D2 Dual D-Tap Fast Charger - 16.8V / 4A

This is the charger that lives in the accessory bag rather than the charge cart. It charges through the D-Tap port at 4 amps, which means it works on any V-Mount or Gold-Mount battery that has a D-Tap interface, without needing the right mount plate for each brand in the kit.

Two D-Tap plugs come off one cable, so two packs go on at once; with only one plug in use the full 4 amps goes to that battery. Output is 16.8V, the charge voltage for the standard 14.4V pack. It is small enough to travel with, which is the point when the alternative is packing a four-bay charger to top up two batteries overnight.
