Four NP-FW50 batteries and quadruple charger

This pack supplies four lithium-ion batteries rated at 7.2V and 1650mAh each, plus a charger that powers all four simultaneously. It targets photographers using Sony mirrorless or NEX bodies that accept the NP-FW50 format.

Quadruple USB charger with dual inputs

The charger accepts 5V 2-3A through either Micro-USB or USB-C and delivers 8.4V at 800mA per slot for one or two batteries, dropping to 500mA when three or four are loaded. An integrated display shows charge status and remaining capacity for each bay.

Interchangeable plate design and bundled cable

Swappable plates let the same charger handle different battery types beyond the included NP-FW50 cells. A USB-C cable is supplied so the unit can draw power from common adapters, power banks or laptop ports without extra accessories.

Questions about this item

How long will the 1650 mAh capacity last in my a7S II?

The 11.8 Wh cells deliver roughly the same run-time as the original Sony NP-FW50; actual shooting time depends on settings such as LCD brightness and video mode.

What does the 5 V 2-3 A USB input mean for charging speed?

With a 15 W USB-C or Micro-USB source the charger supplies 8.4 V at 800 mA to one or two batteries and 500 mA each when three or four are loaded.

Will the 3.5 x 2 x 2.5 inch charger block fit in my camera bag?

The compact brick measures 3.5 by 2 by 2.5 inches and weighs little, so it slips into most accessory pockets alongside the four batteries.
