Sony BC-TRW Travel Charger for W-Series Batteries

The BC-TRW is the compact quick charger for Sony's NP-FW50 W-series battery, the pack used by NEX, a6000-series and first-generation a7 cameras. It charges a spare while you shoot on another, and it is small enough to live in the camera bag.

The AC plug retracts into the body for travel and the input is universal 100 - 240 V, 50/60 Hz, drawing about 6 W. The charger measures roughly 42 x 36.5 x 79 mm and weighs 67 g.
