Two-pack replacement batteries

The Kastar NP-FW50D kit supplies two lithium-ion cells rated at 1650mAh and 7.2V. They replace the Sony NP-FW50 pack used in a wide range of Alpha, NEX and Cyber-shot cameras. Photographers who carry a spare gain a quick swap without hunting for a wall outlet.

USB-C direct charging

Each cell accepts 5V 2A input through a built-in USB-C port so you can top up from a power bank, laptop or wall adapter. No separate cradle is required, freeing bag space and removing a dedicated charger from the travel kit. The pack works with existing Sony BC-VW1 and BC-TRW chargers as well.

Safety circuits and indicators

Over-charge, over-discharge, over-voltage, over-current and over-heat protection meet UL1642 and CE standards. A red LED shows charging and green shows full charge. Users needing higher capacity than 11.8Wh per cell or cameras outside the listed Sony models will need a different solution.

Questions about this item

How long will the 1650 mAh cells last during continuous video recording?

Each pack delivers 11.8 Wh at 7.2 V, giving roughly the same run-time as the original Sony NP-FW50 under identical camera settings.

Do the batteries get hot or noisy when charged through the built-in USB-C port all day?

The integrated protection circuit guards against over-heating, over-voltage and over-current, and the cells are silent solid-state units with no moving parts.

Which charger or adapter must I already own to use the USB-C charging feature?

Any 5 V 2 A USB-C power adapter — such as a standard phone charger or power bank — will charge both batteries via their built-in ports.
