Kastar NP-FW50 Battery & Quad USB Charger

This kit supplies one 7.2 V lithium-ion battery rated at 1650 mAh and a compact charger that accepts four cells simultaneously. It targets Sony mirrorless and compact shooters who need spare power for long sessions without carrying multiple wall adapters. The bundle suits photographers and videographers using compatible Alpha, NEX or Cyber-shot bodies.

11.8 Wh Capacity Decides Runtime

The single figure that determines whether this cell matches your workload is the 11.8 Wh energy rating. A higher-capacity alternative would last longer per charge, while a lower one would require more frequent swaps; no other spec in the data changes that calculation.

Sustained Charging Behaviour

When four batteries are docked the charger delivers 500 mA per slot at 8.4 V, so a full cycle takes longer than the 800 mA rate used for one or two cells. The intelligent display reports status and remaining capacity throughout the process. Micro-USB and Type-C inputs allow power from standard 5 V 2–3 A sources.
