Four NP-FW50 batteries and dual USB charger

This set supplies four lithium-ion batteries rated at 7.2 V and 1650 mAh each, plus an LTD2 charger that accepts Micro-USB or Type-C input. It is built for photographers using Sony Alpha, NEX, Cyber-shot RX10 and SLT cameras that take the NP-FW50 or W-series pack.

Sustained charging with LCD status

The charger delivers 8.4 V at 800 mA whether one or two cells are inserted, and its LCD panel shows real-time capacity for each slot. A 5 V 2–3 A source powers the 15 W input, so both batteries reach full charge without the current dropping off as they fill.

USB power limits and plate flexibility

Micro-USB and Type-C ports cap the input at 5 V, so charging speed depends entirely on the adapter you provide. The chassis accepts interchangeable plates for other battery types, but this pack includes only the NP-FW50 plate.

Questions about this item

Does the charger generate noticeable heat or fan noise when charging two 1650 mAh batteries at 800 mA each?

The LTD2 charger runs silently with no fan; its 15 W input and 8.4 V 800 mA per slot produce only mild warmth during simultaneous charging.

What power source must I already have to run the LTD2 charger at its full 15 W rate?

Any USB power delivery adapter or power bank capable of 5 V at 2–3 A via Micro-USB or USB-C will supply the charger’s 15 W maximum input.

Will these 7.2 V 11.8 Wh batteries communicate correctly with my Alpha 6000 body and VG-C1EM grip?

Yes — the pack matches the Sony NP-FW50 form factor and voltage, so the Alpha 6000, Alpha 6100, Alpha 6300, Alpha 6400, Alpha 6500 and VG-C1EM grip all report capacity normally.
