A two-battery and dual-charger kit for Nikon bodies using the EN-EL15 series — the Z5, Z6, Z6II, Z7, Z7II and the D500, D610, D750, D780, D800, D810, D850 and D7000-series DSLRs. Each cell is 1960mAh at 7.0V, and the charger fills both bays at once with an LCD showing the exact state of each. It takes USB-C input at 5V/2.1A, so it runs from a power bank, laptop or car adapter instead of needing a wall socket — and the whole charger weighs about 89g. A far cheaper way to get a full day of shooting than buying more first-party batteries.
