K&F Concept Sony NP-FW50 1100mAh Battery, 3-Pack + 3-Slot Charger

Three Sony NP-FW50 1100 mAh batteries and a triple-slot charger that charges them all at once. It runs off USB-C, so a power bank, a laptop or the car will top them up. The charger doubles as a carrying box for the batteries. Fully decoded chip: the camera shows the remaining capacity and raises no third-party battery warning. For Sony Alpha 7R, A7S II, A7M2, A7SM2, A7RM2, A3000, A5000, A6000, A6100, A6300, A6400, A6500 and other models.

Three 1100 mAh batteries

Three full-size 1100 mAh batteries work out at roughly 380 shots each — about 1140 for the whole set. In video one battery lasts around 1 h 18 min, measured on Sony A6500, 4K/25P.

Triple-slot charger

The triple-slot charger draws power over USB-C, so a power bank, a laptop or a car charger will do. With a 20 W PD adapter one battery is done in about 2.6 h, two in 3.5 h, all three in 5.5 h. From an ordinary 5 V source three batteries take 7.5 h.

The state is obvious at a glance: a white LED means powered on, breathing red charging below 80 %, breathing blue charging above 80 % and steady green fully charged. The charger housing is made of fire-resistant material and watches temperature, over-voltage, over-discharge, over-current, over-charge and short circuit.
