Two NP-FW50 batteries and dual USB charger

This set provides two lithium-ion batteries rated at 1650 mAh and 7.2 V, together with an LTD2 charger that can fill both cells at once. It targets photographers using compatible Sony Alpha and Cyber-shot bodies who want spare power for long shoots.

Check your camera uses NP-FW50 cells

Verify that your camera accepts the NP-FW50 form factor; the list includes many Alpha and RX models but not every Sony body. The charger needs a 5 V 2–3 A USB source via Micro-USB or Type-C, so confirm you have a suitable power adapter or power bank.

Charger delivers steady 800 mA per slot

Each bay supplies 8.4 V at 800 mA whether one or two batteries are inserted, so charge time stays consistent under sustained use. The LCD shows real-time capacity for both cells, letting you monitor progress during extended charging sessions.

Questions about this item

What comes in the pack and do I need to buy a cable or power adapter separately?

The pack includes one LTD2 dual charger and two NP-FW50 lithium-ion batteries. A Micro-USB cable is supplied; you only need a USB power source such as a 5 V 2–3 A adapter or power bank.

Should I choose the 1650 mAh NP-FW50 or a higher-capacity version for my RX10 II?

This kit only provides the 1650 mAh NP-FW50; no higher-capacity version is listed, so it is the sole option for the RX10 II and other compatible models.

What does the 11.8 Wh rating mean for shooting time in my A6000?

At 7.2 V and 1650 mAh each battery stores 11.8 Wh, giving roughly the same per-charge runtime as the original Sony NP-FW50 in the A6000.
