Three-Battery Kit with Wall Charger

This Kastar NP-FW50 set supplies three 7.4 V 1650 mAh lithium-ion cells plus an AC wall charger. The pack delivers 11.8 Wh per battery and is built as a direct replacement for Sony NP-FW50 and W-series packs. The charger accepts 100–240 V input and folds its flat pins for compact storage.

Suits owners of listed Sony Alpha

Photographers using a6000, a6100, a6300, a6400, a6500, a7, a7 II, a7R, a7R II, a7S, a7S II, ZV-E10 or RX10-series cameras can swap batteries without proprietary chargers. The bundle also fits VG-C1EM and VG-C2EM grips. Shooters who need higher-capacity cells or USB-C charging should look elsewhere.

Charger plugs straight into mains power

The 8.4 V 600 mA charger connects directly to a wall outlet, freeing a USB port and removing the need for a separate power brick. Red and green LEDs show charge status at a glance. Three cells rotate through a single charger, so a spare is always ready for extended sessions.
