Two batteries and a wall charger

This pack supplies two lithium-ion NP-FW50 batteries and a folding-pin AC charger. Each cell delivers 1650 mAh at 7.4 V for 11.8 Wh of capacity. The charger accepts 100 to 240 V input and outputs 8.4 V at 600 mA. A red LED shows charging and a green LED signals a full charge.

Replaces single OEM cells and slow USB charging

The pair doubles the spare capacity you can carry compared with one original battery. Wall charging at 600 mA is faster than most in-camera USB ports. The upgrade is worth it when a day of shooting exceeds one battery or when USB power is unavailable.

Fits Alpha, NEX, Cyber-shot and grip units

Compatible with Alpha models from the 3000 through the 6500 series, full-frame Alpha 7 variants, NEX and SLT bodies, RX10 series cameras and VG-C1EM or VG-C2EM grips. The fold-flat plug keeps the charger slim in a bag. No extra cables or adapters are required.

Questions about this item

What are the exact dimensions of the NP-FW50 batteries so I can confirm they fit my Sony A6000 battery compartment?

Each battery measures 3 by 2 by 2 inches, matching the NP-FW50 form factor used in the Sony A6000 and other listed models.

How do I plug the AC wall charger into a UK socket, and what mistake should I avoid?

The charger has a foldable flat US-style plug; you need a UK travel adapter, and the common error is forcing the flat pins into a UK socket without one.

When will the two 1650mAh batteries need replacing, and what sign shows they are worn?

After roughly 300 to 500 charge cycles capacity drops noticeably; when a full charge delivers much less shooting time than the rated 11.8 Wh, replace the pair.
