Quadruple USB Charger for Sony NP-FW50

This Kastar charger powers up to four Sony NP-FW50 compatible batteries simultaneously. It serves photographers using Alpha mirrorless, NEX, Cyber-shot RX10 or SLT bodies that rely on the W-series pack. The unit accepts Micro-USB or USB-C input and includes a Type-C cable for flexible power sourcing.

Sustained charging behaviour

When one or two batteries are docked the charger delivers 8.4 V at 800 mA per slot; with three or four batteries the current drops to 500 mA each. An intelligent display shows real-time charging status and remaining capacity so you can monitor progress during extended sessions. The 15 W input rating supports the combined load without overheating.

Installation and common issues

Simply insert each battery into a slot and connect the charger to any 5 V 2-3 A USB source using the supplied Type-C cable or a Micro-USB lead. The interchangeable plate design allows future adaptation to other battery types. Users should verify their specific camera or grip model appears in the compatibility list before purchase.

Questions about this item

Does the charger get noisy or hot when all four batteries are charging for hours?

The unit has no fan and draws a maximum of 15 W, so it runs silently and stays only warm to the touch.

What power source do I need to run the Kastar NP-FW50 charger?

Any 5 V USB supply that can deliver 2–3 A — a standard phone charger, power bank, or laptop port with a Micro-USB or USB-C cable.

Will the charger still work with my older Sony NEX-6 and A6000 batteries?

Yes, the NP-FW50 plate fits every Sony NP-FW50 / W-series pack used in the NEX-6, A6000 and all other listed models.
