K&F Concept should be familiar to most people by now, they have steadily expanded their portfolio of products and even if I wasn't aware of it, there are also replacement batteries in the range.
The NP-FZ100 set tested here comes with a USB charging cradle and can charge two batteries at the same time. Of course, it also charges the original battery
Where K&F found the outdated micro-USB connections and cables is a mystery to me.
The batteries are almost identical to the original and have 2280mAh. They feel a little shorter than the original, but this could even out after a few charging cycles.
Except for the somewhat long loading time, a really good replacement set and a recommendable alternative to the original from Sony, which is twice as expensive

The two "NP-FW50" batteries that are 3/4 charged also fit in a Sony A-6400 camera and work reliably without any problems. An enclosed micro-USB cable is firmly plugged into the small charger, another USB-C connection without the supplied cable can also be used.
Especially in cold temperatures or when travelling, you are on the safe side with additional batteries that you can take with you on the go, and I think that both batteries are also safe and last a long time. There were no instructions included, but there is a "CE" mark on the batteries, the charger and the packaging.

After more than 50 charging cycles, absolutely problem-free and reliable in handling

My main camera is a Canon 5dmkiv and I'm a big fan of backup batteries (the camera is battery hungry!) but the OEMs are extremely expensive. My current three Canon batteries are aging, I needed something new for my camera.
I have several Edelkrone motion control products that are also battery hungry and are powered by the LP-E6NH. I order third party batteries for the Edelkrone gear and that was my original intention of trying them out.
These are closer to Canon's surface than any other third party. They charge well with the included charger or Canon's. (And the included charger does a great job with the OEMs, too.)
My 5div recognized these batteries and displayed them at 100% charge and three bars of charge power (max), allows me to register them - gives the same information I get from the OEM. After checking that, I decided to actually use them to take pictures. For the first time I felt safe doing that with this camera.
I'm having a hard time doing a scientific comparison of battery life. I've used each of the K&F batteries in the camera until they were pretty depleted and they seemed to last about the same as my Canon's, maybe a little longer as those age.
So basically these are high quality alternatives to OEM products at a more attractive price point while still offering excellent performance. I would definitely order more.

I use the batteries for my Sony camera, which is getting on in years. The original batteries do not last as long and the original charger can only charge one battery.
The set here makes a good impression of workmanship. The batteries snap into the charger with a rich "click" and are charged. However, it is not the fastest charger. With a maximum of 9W via USB-C, charging takes a while. But, for this, two batteries are charged at the same time. You are very spoiled with fast chargers from today's world, but the manufacturer's specifications come close to 5V/2.1A. That is max. 10W
The batteries themselves fit well into the device and have a great capacity, especially compared to the old batteries I own. It's really fun to take several hundred photos (fast series of sports events) with one battery.
The charger itself is very small and very flexible thanks to Micro USB and USB-C. I think that's really great!
I am very satisfied with it, especially with the price/performance ratio you can be really very satisfied.

Compatible batteries for Sony Alpha 6000 series camera. They work great and it is very convenient to have the external battery charger. Possibility to connect the charger with the supplied USB-C cable or micro-USB (not included). I am fully satisfied with the construction quality, compatibility (I have an alpha6100) and charging speed (I use a 2 amp wall charger). Perhaps they have a slightly shorter life than the original SONY batteries but I have not noticed the difference, plus with what an original battery costs at a little more than half the price you will have 2 and a dedicated charger.

For extended use with only short breaks, a second battery and external charger are essential. The lack of the required USB power adapter is easy to live with these days and doesn't represent a negative for me. You almost always have suitable power adapters for other devices in your household that you can easily use as a backup. It's good for the environment!

The batteries came half charged so I used the charger overnight to charge them to 100%. I then left both batteries for a few days before testing them with my Sony camera. Both batteries showed a charge of 100%.
One of my earlier third party NP FW batteries had a habit of slowly draining at about 1% per day when not in use and the camera was not in use, while another set completely failed within a year of use. This seems to hold the charge well for the time being. If I see problems I will update here.
As mentioned in the title of my review, the charger can be conveniently connected via a typical USB connector as well as a newer format (USB-C). The lights correctly indicate whether the battery is charged or not, and other brands of NP-FW50 batteries can be used.
Overall very good quality and no problems so far.

The charger does exactly what it's supposed to: charge two batteries simultaneously. It works very well; the indicator light makes it easy to check whether the battery is full or still charging. The charger can be connected to a power adapter or a computer via a USB port. Would I buy it again? Absolutely!
