Three-battery pack for Sony mirrorless

The Kastar NP-FW50 kit supplies three 7.2 V 1650 mAh lithium-ion cells and a quadruple USB charger. Each battery stores 11.8 Wh and fits Sony Alpha and NEX models from the a5000 through the a7R II series, plus Cyber-shot RX10 variants and the ZV-E10. The bundle targets photographers who need several ready spares for long shooting days.

Quad charger with dual USB inputs

The included charger powers up to four batteries simultaneously through either Micro-USB or USB-C ports, accepting 5 V at 2–3 A. Output adjusts automatically: 8.4 V at 800 mA for one or two cells, dropping to 500 mA when three or four are inserted. A compact display shows charge status and remaining capacity for each slot, and swappable plates allow future compatibility with other battery types.

Simple USB-powered setup

Connect the supplied Type-C cable to any 5 V 2 A or 3 A source such as a wall adapter, power bank or laptop port — no AC cable is required. Insert batteries in any order; the intelligent circuit detects cell count and sets the correct current. The only common issue is attempting to run the charger from a low-current port, which prevents the 800 mA dual-bay mode from activating.

Questions about this item

How often will the NP-FW50 1650 mAh batteries need replacing?

Lithium-ion cells typically last 300 to 500 full charge cycles before capacity drops noticeably; with three batteries in rotation you can spread wear and extend the interval between replacements.

What limits continuous shooting when all four charger bays are used?

The charger drops to 500 mA per bay when three or four NP-FW50 packs are inserted, so replenishing depleted 11.8 Wh cells takes longer than with one or two batteries.

How much heat does the quad charger produce during an all-day session?

At 15 W maximum input the compact USB-C / Micro-USB unit stays warm but not hot; the intelligent display lets you monitor each bay without the charger becoming a thermal concern.
