Dual USB Charger for Sony NP-FW50

The Kastar NP-FW50 LTD2 charger powers two Sony NP-FW50 or W-series batteries simultaneously. It suits photographers who carry spare cells for long shoots with Alpha 7, Alpha 6000 or Cyber-shot RX10 series cameras. The compact unit replaces the original BC-VW1 or BC-TRW charger and works with grips such as the VG-C1EM and VG-C2EM.

Micro-USB and Type-C inputs with 5 V supply

The charger draws 5 V at 2–3 A (15 W) from any standard USB source, so it can run from a power bank, laptop or wall adapter without a dedicated AC brick. Each bay delivers 8.4 V at 800 mA whether one or two batteries are inserted. An LCD panel shows real-time capacity and charging status for both slots.

Interchangeable plates and bundled Micro-USB cable

Swappable plates let the same chassis charge other battery types when the appropriate plate is fitted. A Micro-USB cable is included for immediate use; Type-C cables are not supplied. Buyers who want a Type-C cable or plates for non-Sony batteries must source them separately.

Questions about this item

What charging current does the dual-slot output deliver when both bays are occupied?

Each slot supplies 800 mA at 8.4 V even when two NP-FW50 packs are charging simultaneously.

How much heat or fan noise should I expect during an all-day charging session?

The compact 5×3×1 inch enclosure has no fan and runs cool because the 15 W input is spread across the two low-current outputs.

Which power source must I already have to run the charger?

Any 5 V USB supply rated at 2 A or 3 A — such as a phone adapter, power bank or laptop port — works through the Micro-USB or Type-C input.
