Great FW50 batteries with USB-C
Since FW50 batteries are so small, I didn’t expect to find a FW50 battery with USB-C charging capabilities.
Overall the battery is about a half-milliliter wider than the official Sony FW50 but it still fits inside the camera well. I tested with Sony ZV-E10 and the battery fit smoothly and performed flawlessly.
Due to its ever so slightly wider shape, I found this battery doesn't fit some third party battery chargers.
The USB-C charging is of course appreciated, as this means I can more easily charge batteries on the go and not have to worry about a separate battery charger.
Overall it’s another winner product from K&F concept.
