Kastar NP-FW50 2-Pack for Sony mirrorless

This kit supplies two 7.2 V lithium-ion batteries rated at 1650 mAh and 11.8 Wh each, matching the NP-FW50 form factor used across Sony Alpha and NEX mirrorless bodies. It targets photographers and videographers who need reliable spare power for extended shoots or travel.

Quadruple charger with dual USB inputs

The included charger accepts Micro-USB or USB-C at 5 V 2–3 A and can charge up to four batteries simultaneously. An intelligent display shows individual charging status and capacity, while the swappable plate design allows future compatibility with other battery types.

Capacity and charging headroom

Each battery delivers 11.8 Wh, enough for several hundred stills or roughly an hour of continuous video on compatible bodies. The charger outputs 8.4 V at 800 mA for one or two cells and 500 mA for three or four, so full charges take longer when all four slots are occupied.

Questions about this item

How often will the NP-FW50 1650 mAh batteries need replacing under normal use?

Lithium-ion cells typically last 300 to 500 full charge cycles before capacity drops noticeably, so replacement timing depends on how frequently you deplete and recharge the two included packs.

What limits the charger when all four bays are used continuously?

With four batteries inserted the output falls to 500 mA per bay, extending each charge to roughly three hours and making total throughput the practical bottleneck.

How much heat or noise does the quadruple charger produce during all-day operation?

The compact 15 W unit has no fan and runs warm but not hot; the only audible sound is a faint coil hum that is inaudible beyond a few centimetres.
