This is easily the best third party battery I have owned for a camera. In some ways, it is better than the OEM battery. I have always purchased third party batteries for my backup batteries. I have never had a bad experience and they are just so much less expensive than OEM. That said, the OEM battery is still the best option for battery life and longevity. I just don’t believe the higher price is worth it. The K&F CONCEPT battery is in the middle price range and is probably the best option for most owners. I have found the battery life to be as good, if not better than Fujifilm’s battery. It is rated higher, but that doesn’t always mean it will last longer… well in this case, it does. The USB-C port on the battery is a convenience. I have charged my batteries both in the camera and in a third party charger that charges 2 at a time. The USB-C will just add another option to that list. BTW, this battery charges nice in camera and in my charging dock… no issues. I am really happy with this battery and will probably stick with K&F CONCEPT batteries in the future. I already use their camera cages and other accessories. So happy to buy from a trusted brand.
