Two-pack replacement for Sony NP-FW50

This two-pack supplies 1650mAh lithium-ion cells rated at 7.2V and 11.8Wh each. They fit a long list of Sony mirrorless and compact cameras including Alpha 7 series, Alpha 6000 series, RX10 series and NEX models. Photographers who need spare power for long shoots can swap cells without carrying a separate charger.

USB-C charging with built-in protection

Each battery accepts 5V 2A input through a USB-C port so it can be topped up from a wall adapter or power bank. A red LED shows charging and green shows full. Internal circuitry guards against over-charge, over-discharge, over-voltage, over-current and over-heating, and the cells meet UL1642 and CE safety standards.

No external charger required

Because the USB-C port is on the cell itself, the bundle eliminates the need for a dedicated BC-VW1 or BC-TRW charger. The package contains only the two batteries; no cables or adapters are included. Shooters who already own USB-C cables gain a lighter kit, while those who prefer dock charging must supply their own station.

Questions about this item

How do I install the Kastar NP-FW50D batteries and what step is often missed?

Slide each battery into the camera's battery compartment until the latch clicks; the step people miss is pressing the battery-lock lever fully down so the pack cannot pop out during shooting.

What maintenance or replacement will the NP-FW50D pack need later?

Lithium-ion cells degrade after several hundred charge cycles; when run-time drops noticeably, replace both packs together to keep capacity balanced.

What limit appears first during sustained use of the NP-FW50D?

The built-in protection circuit cuts output if the cell temperature rises too high or voltage falls below the safe threshold, stopping the camera until the pack cools or is recharged.
