Replacement power kit

The Kastar NP-FW50 kit supplies one 1650mAh lithium-ion battery and an AC wall charger with a foldable flat plug. It is designed for owners of compatible Sony Alpha, NEX, Cyber-shot RX10 and ZV-E10 cameras who need a spare or replacement power source. The battery delivers 7.4V and 11.8 Wh capacity for extended shooting sessions.

Build integration

The charger accepts AC 100-240V input and outputs DC 8.4V at 600mA, so it plugs directly into mains sockets worldwide without a separate adapter. Its foldable pins reduce bulk in a gear bag. The battery fits the same compartment as the original Sony NP-FW50 and works with the BC-VW1 and BC-TRW chargers already in your kit.

Sustained operation

An LED shows red while charging and green once the cell reaches full capacity or stands by. The 600mA charge rate replenishes the 1650mAh cell steadily without rapid heating. This makes the kit reliable for multi-day trips where mains power is available each night but high-speed top-ups are not required.

Questions about this item

How many shots can I expect from the 1650mAh battery before it needs recharging?

The battery stores 1650mAh at 7.4V, giving 11.8Wh; actual shot count depends on the camera model and how you use it.

Does the charger get hot or make noise when left plugged in all day?

The charger draws AC 100-240V and outputs DC 8.4V at 600mA with no fan, so it runs silently and stays cool during continuous use.

Will this kit work with my Sony Alpha 6400 straight out of the box?

Yes, the NP-FW50 battery fits the Alpha 6400 and the included AC wall charger with foldable plug powers it directly from mains.
