Two-pack NP-FW50 for Sony Alpha 7 II and 7R

This set includes two lithium-ion batteries and a dual-slot USB charger. Each cell delivers 7.2 volts and 1650 milliampere-hours for 11.8 watt-hours of capacity. The pack suits photographers who need reliable spares for long shooting days with compatible Sony mirrorless or Cyber-shot cameras.

Dual LCD charger with Micro-USB and Type-C inputs

The LTD2 charger powers two batteries simultaneously at 8.4 volts and 800 milliamps per slot. Its built-in screen shows real-time capacity and charging status. A Micro-USB cable is supplied and the unit accepts 5-volt inputs up to 3 amps from standard power banks or wall adapters.

Limited to NP-FW50 form factor

The charger plates are fixed for this battery type and cannot accommodate larger packs or different voltages. Output current stays at 800 milliamps per bay, so full recharges take several hours. Users needing faster turnaround or higher-capacity cells must seek alternative systems.

Questions about this item

What USB inputs does the LTD2 charger accept and what output does it deliver per battery?

The LTD2 charger has Micro-USB and Type-C inputs at 5V 2-3A 15W and charges each NP-FW50 battery at 8.4V 800mA.

What are the physical dimensions of the charger and two-battery pack?

The pack measures 5 by 3 by 2 inches, making it compact enough for a camera bag.

How do you operate the dual-slot charger and what mistake should be avoided?

Insert up to two batteries, connect a 5V 2-3A USB source to Micro-USB or Type-C, and watch the LCD for status; the common error is using a low-power port that cannot supply 15W.
