K&F Concept Sony NP-FW50 1100mAh Battery with USB-C Charging, 2-Pack

Two Sony NP-FW50 1100 mAh replacement batteries with a USB-C port built into the battery. A cable and a power bank, laptop or car charger are all you need, with no separate charger to carry. Fully decoded chip: the camera shows the remaining capacity and raises no third-party battery warning. For Sony Alpha 7, A7 II, A7R, A7R II, A7S, A7S II, A3000, A5000, A6000, A6300, A6500, NEX-3, NEX-5, NEX-6, NEX-7, SLT-A33, SLT-A35 and other models.

Two 1100 mAh batteries

The batteries have a capacity of 1100 mAh, that is 7.9 Wh at 7.2 V.

Charging over USB-C

The battery charges straight over USB-C, so on the road a cable and any source will do — a power bank, a laptop or a car charger.

The chip watches over-charge, over-discharge, over-voltage, over-current, short circuit and overheating, and switches to trickle charging once full.
