Three-battery pack with dual-slot USB charger

The Kastar NP-FW50 kit supplies three 1650 mAh lithium-ion cells and an LTD2 charger that powers two batteries at once from any 5 V USB source. Each cell stores 11.8 Wh at 7.2 V and matches the form factor of the original Sony NP-FW50. Photographers using compatible Alpha, NEX, Cyber-shot RX10 or SLT bodies gain extended shooting time without proprietary wall adapters.

Check camera model and USB power capability

Verify that your camera appears in the supported list covering Alpha 7, 7R, 7S and 7 II series, Alpha 6000 through 6500, NEX models, Cyber-shot RX10 versions and SLT-A33 through A55 bodies. The charger draws up to 15 W from a 5 V 2-3 A USB port, so confirm your power bank, AC adapter or laptop port can deliver that current. No AC cable is included, only a Micro-USB lead.

LCD charger adds simultaneous charging

The LTD2 unit accepts both Micro-USB and USB-C input and shows real-time capacity and charging state on its built-in display. It outputs 8.4 V at 800 mA per slot whether one or two batteries are inserted, cutting total recharge time versus single-bay units. Interchangeable plates are supported for other battery types, though only NP-FW50 plates are supplied in this pack.

Questions about this item

What is included in the pack and what must be bought separately?

The pack contains three NP-FW50 7.2 V 1650 mAh lithium-ion batteries, one LTD2 dual-slot charger with LCD status display, and a Micro-USB cable; a 5 V 2–3 A USB power adapter is not included.

Which capacity version should I choose for my Sony a7 II?

Each battery in this set is rated 1650 mAh and 11.8 Wh, matching the original NP-FW50 specification for the a7 II, a7R II and a7S II.

What does the 800 mA output mean when charging two batteries in the camera bag?

The charger delivers 800 mA per slot when both slots are occupied, so two depleted 1650 mAh cells take roughly two hours to reach full charge from a 5 V 2 A source.
