Kastar NP-FW50 battery and quad charger

This set supplies one 1650mAh lithium-ion cell and a four-bay charger for Sony cameras that use the NP-FW50 pack. The charger accepts both Micro-USB and USB-C power inputs and can replenish up to four batteries simultaneously. It is aimed at photographers who need extra runtime for long shoots or travel without access to mains power.

Replaces single-bay chargers and lone OEM cells

Moving from a one-at-a-time charger to this four-slot unit cuts total recharge time when you carry several spares. The swap is worthwhile if you regularly deplete two or more packs in a day and want them ready by the next morning. Users who only ever shoot with a single battery will not benefit from the extra bays.

Sustained charging splits current across bays

With one or two batteries inserted the charger delivers 800mA per slot at 8.4V; with three or four it drops to 500mA each. The intelligent display shows individual capacity so you can track progress during extended sessions. Heat buildup remains modest because the charge rate scales down automatically as more cells are added.

Questions about this item

What are the physical dimensions of the charger unit?

The charger measures 3.5 by 2 by 2.5 inches, so check that your bag or shelf space accommodates that footprint.

How do I power the quad charger and what common mistake should I avoid?

Connect the supplied Type-C cable to a 5V 2-3A USB source; using a lower-amperage port will slow charging or prevent all four slots from operating at once.

When should I replace the NP-FW50 battery and how can I tell?

Replace the 1650mAh 7.2V pack when run-time drops noticeably or the charger's capacity indicator shows a significantly reduced full-charge reading.
