Three-battery kit with four-slot charger

This Kastar NP-FW50 kit includes three lithium-ion batteries rated at 7.2 V and 1650 mAh each, plus a compact charger that can replenish four cells simultaneously. It targets photographers using Sony mirrorless or SLT bodies that accept the NP-FW50 form factor.

Charger limited to USB 5 V input

The charger draws 5 V at 2–3 A (15 W) through either Micro-USB or USB-C and delivers 8.4 V at 800 mA for one or two batteries, dropping to 500 mA when three or four are loaded. Charge time therefore scales with the number of cells and the current capability of the USB power source used.

Drop-in installation, watch cable power

Batteries slide into the camera exactly like the original Sony units, and the charger needs only a standard USB-C cable (included) and any 5 V 2 A or higher adapter. The main practical issue is that under-powered USB ports will lengthen the cycle or stop charging when all four slots are occupied.

Questions about this item

Should I pick the triple-battery pack or a single battery for my Sony Alpha 6000?

The pack includes three 1650 mAh NP-FW50 batteries plus a charger that can charge four at once, so you get spare power and a way to top them all together.

What does the 11.8 Wh rating mean when I am shooting with an Alpha 6400?

At 7.2 V and 1650 mAh each battery delivers 11.8 Wh, giving roughly the same run-time as the original Sony NP-FW50 in cameras such as the Alpha 6400.

How fast will the quadruple charger fill the batteries when I plug it into a USB-C source?

The charger takes 5 V at 2–3 A via Micro-USB or USB-C and outputs 8.4 V at 800 mA for one or two batteries or 500 mA each for three or four.
