Kastar NP-FW50 four-battery kit

This pack supplies four 7.4V 1650mAh lithium-ion cells and a matching AC wall charger. It is built for photographers who shoot with Sony mirrorless bodies such as the Alpha 7 series, Alpha 6000 series, NEX models or the ZV-E10 and want spare power for long sessions.

Sustained shooting with the wall charger

Each cell stores 11.8 Wh and the charger delivers a steady 8.4V 600mA output from any 100-240V mains supply. The foldable flat plug keeps the unit compact while the red and green LEDs show charge progress without needing the camera screen.

Check your camera and grip compatibility

Verify that your body accepts the NP-FW50 form factor; the list covers many Alpha, NEX, Cyber-shot RX10 and ZV-E10 models plus VG-C1EM and VG-C2EM grips. If your camera uses a different battery shape or voltage this kit will not fit.

Questions about this item

Does the Kastar NP-FW50 charger produce noticeable heat or noise when left plugged in all day?

The wall charger runs silently with no fan. It draws AC 100~240V and outputs DC 8.4V at 600mA, so warmth stays low during extended charging sessions.

What camera body must I already own for these NP-FW50 batteries to work?

They fit Sony models such as the ILCE-7SM2, ILCE-6400, ILCE-6500, ZV-E10, NEX-6, NEX-7, SLT-A55 and the full list shown in the compatibility table.

Can I mix these Kastar NP-FW50 packs with older Sony NP-FW50 batteries I already keep?

Yes. Each Kastar cell is 7.4V 1650mAh (11.8 Wh), matching the original spec, so they charge on the same BC-VW1 or BC-TRW charger and share power in grips like the VG-C2EM.
