A solid battery replacement
K&F is quickly becoming one of my favorite off brands for photography. Every product I've gotten from them has impressed me in some way or another. These batteries are no different.
The batteries themselves fit perfectly and worked the first time reporting their battery percentage. The casing is nice - a touch more texture than my sony batteries but it's a good feeling battery.
The charging cradle is where I'm most impressed though. While it comes with a micro USB cable, there's also a spot to use a USB C cable to charge the batteries through the cradle. Anything that can reduce the number of cables I have to bring with me is a win in my book. And the charging cradle helpfully has the red and green LED indicator to show when batteries are charging versus full. I much prefer that to the LED on/off style since I can't ever remember which means charging and which means full.

Overall, a solid battery replacement set for anyone still using a sony camera with W batteries.

Quality Replacement with Proper Fit for Sony Cameras
This review is for the Sony NP-FW50 version

I tested these for a couple weeks with several charge cycles. I have also owned various other brands of aftermarket chargers and batteries. Having had good luck with K&F camera to lens adapters, I was looking forward to try their batteries.

Packaging:
Good quality shipping box. Includes a USB type A to USB Micro cable. Does not include a USB-C cable just a USB-A to USB Micro.

Charging:
Batteries arrived charged to about 65 percent according to what my Sony A7 was reporting and they do fully charge to 100%, but this can take quite a while, perhaps longer than the 2.5 hrs claimed. The LED goes from Red to Green on full charge which is nice and intuitive unlike on/off or blinking LEDs that other companies employ.

Battery
The tolerances on these are excellent. They fit several of my Sony camera bodies just as well as the factory batteries, not loose nor tight. They also fit the Sony OEM charges quite well. Battery power is better than other aftermarket batteries, but I don't think they are a good as the Sony factory units, but then again you get two K&F batteries for the price of one Sony branded battery.

My only gripe is that on the first couple uses, the batteries were a rather tighter fit on the charger than what I expected, but they do seem to go in easier after several uses and after about a month it's fine.

Overall I would say these are high quality replacement batteries and better than most competitors. The high tolerances of the batteries make a big difference as fitment can be just as important as battery life.

Charger accepts both USB C and A types
Batteries came half-charhed, so I have used charger overnight to give them 100% charge. I then left both batteries for another few days before I have tested them with my Sony camera. Both batteries shown 100% charge.
One of my previous sets of NP-FW non-Sony batteries had a habbit to slowly discharge about 1% per day of not being used and being out of camera, while another set died completely within a year of use. This one seems to hold the charge well for now. If I will see any problems, will update here.

As mentioned in the title of my review, the charger conveniently could be connected via typical usb, as well as newer format - usb C. The lights indicate correctly if battery is charged or not and accepts other brands of NP-FW50 batteries.

Overall, very decent quality and no issues so far.

Best Batteries I have! My First K&F Concept Product
I was looking for extra batteries for my Sony a6400 and watched a comparison showing 4 different battery brands competing in which K&F Concept was the winner for longevity, so I decided to purchase them. The proof is in the pudding is all I have to say, these batteries have been with me for over a year and still hold up great as they did when I first got them and they can easily be placed in the charging dock for easy transport. And for the price, you cannot beat these!
