I used this battery for the first time in my camera for the eclipse. It charged quickly and worked great. I love the fact that you can charge it in a traditional charging base or simply by connecting a usb-c cable to it. You can never go wrong with K&F products.

These batteries appear to work as well as the oem one's. I have had no issues with them.

These are proving really useful as spare batteries for my Sony A7s. NP-FW50s are notoriously weak batteries that drain in no time, and these are pretty similar to the Sony originals, but I like the advantage of being able to charge them by USB-C. Saves me dragging another set of chargers around with me.
Though I'm really pleased with them, they really missed the boat with the USB-C port placement. If they'd put that on the bottom of the battery as it's installed in the camera, they could be charged on the go, or act a kind of dummy battery to pull in a source from something like a v-lock battery. But that's nitpicking. Good value and effective.

The thing I like the most about this battery is that I can recharge it in my car with just a USB cable; no need to take along a battery charger. It's a small thing, but I have enough trouble remembering the equipment I need for a photo safari. One less thing is helpful.
It also works well in my Fuji GFX 100S. Just like the original equipment. I can't say if it takes the same number of shots as the original, but it's close enough for me.
It arrived with a charging cable to boot. Overall, I'm pleased.

Was able to charge battery with USB C port, with camera body and with external charger. Battery life seems about the same as original battery. Highly recommended!

We are using this with our GFX 50 SII alongside two Fuji brand batteries. So far, they appear to perform the same, with one significant difference: the K&F Concept can be charged with a common charging cable. It has Type C Fast Charging, making it very convenient, especially when in the field. This is a brilliant feature. We wish all camera manufacturers would adopt this ability.

This battery is just as good as the OEM battery for photography. I can just about as many shots out of this battery on my X-H2 as i do with the OEM battery minus a handful. There is a slightly noticeable difference when running video on this battery as it gave about 20 mins less record time than the OEM. This wasn’t a scientific study and other factors may have played into the shorter runtime such as camera temp.
The white color of the battery is a nice touch to the traditional boring black batteries. This color makes your K&F battery stand out amongst the rest. The usb-c port allows for you to charge on the go without the need of a charging station.
