Three-battery kit with dual USB charger

This set includes three lithium-ion NP-FW50 cells rated at 7.2 V and 1650 mAh each, plus an LTD2 dual-slot charger. The bundle targets owners of Sony Alpha mirrorless and Cyber-shot RX10 cameras who want spare power and flexible charging away from a wall outlet.

Travel photographers needing extended shooting time

The pack suits users who carry multiple bodies or shoot long sessions and want to swap cells without hunting for a proprietary AC adapter. Photographers who rely on in-camera USB charging or who need a charger that also powers other battery formats will not be served by this kit.

Dual-slot charger with Micro-USB and Type-C input

The LTD2 unit accepts 5 V at 2–3 A through either port and can charge two batteries simultaneously at 8.4 V 800 mA per slot. An integrated LCD shows real-time capacity for each cell, and the package includes a Micro-USB cable so the charger works with common power banks or laptop ports.

Questions about this item

Does the charger need a separate wall adapter or can it run from a USB port?

The LTD2 charger draws 5 V at 2–3 A through its Micro-USB or USB-C input, so any 15 W USB power source will run it without a dedicated wall wart.

Will the NP-FW50 packs work in an older SLT-A35 body that originally used the BC-VW1 charger?

Yes, each 7.2 V 1650 mAh cell matches the NP-FW50 spec used by the SLT-A35 and the bundled charger replaces the BC-VW1 function.

How can I confirm both batteries are charging at the same time on the LCD?

The intelligent LCD shows independent status bars for each slot; when both read 8.4 V and 800 mA output the two cells are charging together.
