Three-battery pack with foldable AC charger

The Kastar NP-FW50 kit supplies three lithium-ion cells rated at 7.4 volts and 1650 milliampere-hours each, plus a compact wall charger. It replaces the Sony NP-FW50 and W-series batteries used across the RX10 III, RX10 IV, Alpha 3000 and many other E-mount and A-mount cameras. Photographers who carry a spare for long shoots or travel will appreciate the ready-to-go triple set.

100–240 V input with LED status

The charger accepts worldwide mains voltage from 100 to 240 volts at 50 to 60 hertz and delivers 8.4 volts at 600 milliamps to each cell. A fold-flat plug keeps the unit slim in a bag, while a red LED shows charging and a green LED signals standby or full charge. No fan or active cooling is required, so operation stays silent.

Fits existing camera bodies and grips

Each battery matches the original NP-FW50 form factor, so it slides into the RX10 series, Alpha 6000-series, Alpha 7-series, NEX models, SLT bodies and the ZV-E10 without adapters. The pack also works with Sony VG-C1EM and VG-C2EM vertical grips. Users who need more than three cells or a car-charging option will need a separate solution.

Questions about this item

How do I install the NP-FW50 batteries and charger?

Slide each 7.4 V 1650 mAh battery into the camera until it clicks, then connect the AC charger to a 100–240 V outlet and insert a battery; the LED turns red while charging and green when full.

What maintenance or replacement will the NP-FW50 pack need later?

Lithium-ion cells lose capacity over time; expect to replace the three batteries after roughly 300–500 full charge cycles when run-time drops noticeably.

What limit appears first during sustained use of the NP-FW50 batteries?

Each cell holds 11.8 Wh, so extended video recording or continuous shooting will drain a battery in about one to two hours before a recharge is required.
