Using my NEX camera body with original charger and cable.
Not useful at all, as I can only charge while battery is in the camera.
Needed a way to charge batteries externally.

Picked out the 2 pack version.
This includes: 2 1100mAh rechargeable batteries, 2 charging cables, 2 instruction sheets.
Charging cables are 24" from end to end, with a built in hoop and loop strap.
USB-C at the camera end and USB-A at the charging end.
The batteries are white on the front and sides.
USB-C port is on the front along with the built in charging LED.
Back is gray and has the information label.

Charging.
Connect with the provided charging cable.
Plug into the battery charging port.
This port can only be accessed out of the camera.
Power bank was my preferred way to charge the batteries.
LED color is red while charging. Green when fully charged.
Side note.
The batteries will also charge inside the camera using the OEM NEX charger.

Overall.
High quality replacement NP FW50 batteries.
Batteries are easy to find as they are white and gray in color.
Include USB-C to A charging cable with built in hoop and loop strap.
Nice long run times while using in the camera.
Very low drainage while sitting in camera for long periods of time.
I prefer these over the OEM and I can charge outside of the camera.
Hope this was helpful.
