I was a bit skeptical at first, even though the promises are really bold.
I was not disappointed. The battery lasts twice as long as the original. The classic fear of an empty battery is finally unfounded

I am loving this battery! Apart from having spare batteries at hand to supplement the original one (that came with my Sony ZV-E10 which doesn't last too long), I love the ability to charge these outside the camera using USB C. I've charged it using a wall charger, a car charger and a power back in different scenarios - and it is a life (and time) saver!!
I also like the LED in each battery that is red while charging, and turns green when the battery is charged.
The battery fits my Sony camera perfectly, and the camera didn't show any warning about the battery not being original, etc.

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.

I have owned many batteries for my Sony A7 and this aftermarket battery with built in USB-C is a game changer. In the past I would have to just bring hands full of batteries with me. The next progression was a USB powered charger. Now with the built in USB port, that takes it to the next level. I almost always have a battery pack with me now between the phones, tablets, etc. that I carry. So now that the port is built in, I can literally take out a low batt and plug the USB cable into the batt and go.
Battery life so far is good, but longevity will be the ultimate indicator for whether this is a good value or not. For now everything works as it should so it gets 5 stars.

The battery keeps up well with the original batteries. Advantage: Cheaper, can be charged with a USB-C cable, protective cover on the contact side (for transport)

It’s cool to be able to hook these up to a cable in a pinch. They last a few minutes longer than the stock battery.

The problem with my zv e10 is that these batteries are so small you need to have a bunch on hand if you are out shooting video,that means having to carry around a charger as well. These are super convenient to be able to charge directly from any usb c charger cord like the one in my car all the time. This is a great invention!

Since I like to take time-lapse series, I thought running one would make for a good test. After fully charging the battery, I installed it in a Sony A7R, connected an intervalometer configured to fire every 10 seconds, and let it do its thing. The result? 754(!) RAW images were recorded to the sdcard before the camera shut down from lack of power.
Between the excellent performance and the integrated USB C charge port (a really nice feature—one less charger to worry about) I’ve got to say, I’m terribly impressed!
