Four NP-FW50 cells and a dual USB charger

The kit supplies four lithium-ion batteries rated at 1650 mAh and 7.2 V each, plus a LTD2 charger that accepts Micro-USB or USB-C input. It targets Sony shooters using Alpha mirrorless or Cyber-shot models that take the NP-FW50 format.

Charger sustains 800 mA per slot continuously

When both bays are occupied the charger delivers 800 mA to each battery without dropping current, so a full cycle takes roughly the same time as a single cell. The LCD panel shows real-time capacity for both positions during the session.

Slide-in plates and cable included

Batteries drop into the swappable plates without tools, and the supplied Micro-USB cable plugs into any 5 V 2-3 A source. The charger will not operate from a 1 A port, so builders needing faster than 8.4 V 800 mA output must use a stronger adapter.

Questions about this item

Does the LTD2 charger get hot or make noise when charging two NP-FW50 batteries all day?

The charger runs from a 5V 2-3A USB source and delivers 8.4V at 800mA per slot, so heat and noise stay low during extended use.

What power source do I need to run the LTD2 charger with its Micro-USB or Type-C input?

Any 5V 2-3A USB adapter or power bank rated for at least 15W will drive the dual charger.

Will these 1650mAh 7.2V batteries work in my older Sony NEX-6 or A6000 without issues?

Yes, the NP-FW50 cells are listed as compatible with the NEX-6, ILCE-6000 and many other Sony models.
