A two-battery and dual-charger kit for Nikon bodies using the EN-EL25, including the Z30, Z50 and Z fc. Each cell is rated 1200mAh, and the dual-bay charger fills both at once with an LCD showing the state of each. USB-C input means it charges from a power bank or laptop rather than tying you to a wall socket — useful on travel and event days when the camera is the thing that runs out first.
