Four NP-FW50 batteries with wall charger

This kit supplies four lithium-ion NP-FW50 cells rated at 7.4 V and 1650 mAh each, plus an AC wall charger with a foldable flat plug. It is aimed at photographers using Sony Alpha mirrorless or NEX cameras who want spare power for long shoots or travel.

Check camera and grip compatibility

Verify that your camera body or vertical grip accepts the NP-FW50 form factor; the list covers Alpha 7, 7 II, 7R, 7R II, 7S, 7S II, 6000 through 6500 series, A3000, A5000, A5100, NEX models, SLT-A33 through A55, Cyber-shot RX10 series and ZV-E10. Also confirm your region uses 100–240 V mains so the charger operates without a voltage converter.

Charger fits standard outlets

The charger plugs directly into a wall socket and delivers 8.4 V at 600 mA, with a red LED for charging and green for standby or full charge. Using this external unit leaves the camera’s USB port free for data transfer or other accessories while batteries replenish independently.

Questions about this item

What comes in the pack and do I need anything else to charge the batteries?

The pack includes four NP-FW50 lithium-ion batteries and one AC wall charger with a foldable flat plug. The charger accepts 100-240 V mains power so no extra adapter is required.

Should I choose this 1650 mAh version or a higher-capacity alternative?

Each battery is rated at 1650 mAh and 11.8 Wh at 7.4 V. If your shooting sessions regularly exceed one full charge, the four-battery pack lets you rotate cells without waiting for a recharge.

How long will a 1650 mAh battery last in my Alpha 7 II?

The charger delivers 8.4 V at 600 mA, so a depleted cell takes roughly three hours to reach the green LED. Actual shooting time depends on camera settings, but the 11.8 Wh capacity matches the original Sony NP-FW50 specification.
