Two NP-FW50 batteries and a foldable AC charger

The pack supplies two lithium-ion cells rated at 7.4 V and 1650 mAh each, plus a wall charger with a foldable flat plug. It is aimed at photographers using compatible Sony Alpha, NEX, Cyber-shot RX10 or ZV-E10 bodies who want spare power for long shooting days.

Check your camera model against the compatibility

The batteries replace the Sony NP-FW50 and W Series cells and work with the BC-VW1 and BC-TRW chargers. Verify that your specific body — whether Alpha 7 series, 6000 series, NEX, SLT, RX10 or ZV-E10 — appears in the supported list before ordering.

Charger runs on 100–240 V AC

The unit accepts worldwide mains voltage and shows red while charging, green when full or on standby. Its foldable pins keep the profile slim for travel bags. The two batteries free the shooter from a single-cell limit without needing a proprietary Sony charger.

Questions about this item

Does the pack include both batteries and the charger, or do I need to buy the AC adapter separately?

The pack contains one foldable-plug AC wall charger and two NP-FW50 lithium-ion batteries, so nothing else is required to start charging.

Which capacity version of the NP-FW50 is supplied — are there higher-capacity options in this listing?

Both included batteries are rated at 1650 mAh and 11.8 Wh; no other capacity is offered in this pack.

What does the 1650 mAh rating actually deliver when shooting with an Alpha 7 II?

Each 7.4 V, 1650 mAh cell stores 11.8 Wh, giving typical mirrorless shooting time comparable to the original Sony NP-FW50.
