The K&F CONCEPT NP-FZ100 camera battery charger was delivered quickly.
It is packaged neatly and appears to be of high quality.
However, the item description on the product page is a bit muddled and confusing. You have to look carefully at which battery you really need.
But the batteries are no worse than the originals from Sony.
They load quickly and reliably.
Of course, not much can be said about the longevity, but so far I'm really satisfied.

In general they are good for the price they cost, I have 2 originals and these 2 generic ones, when I make a video I use the originals and when I take photos I use these from K&F, as far as possible of course.

The K&F CONCEPT NP-FZ100 work without any problems in my Sony A7R IV. There are no warning messages or anything like that either.
Since I own several replica batteries, I started measuring the capacity of these. I was able to determine 1911 mAh here, which is a "medium" capacity for a replica battery. In my measurements, Sony's own battery has a capacity of 2256 mAh, which is around 18% more. Considering the price difference, totally okay!
The included charger is also very compact and works well. While this is very simple, it is also light and small, good for travel and light luggage.

Just as good as OEM batteries.
As we all know, third party camera batteries can be a bit controversial as some batteries are enlarged or just fail. OEM batteries are more known for being very reliable and punctual. However, this comes at a much higher cost.
I would say these do the job and only time will tell how good they are for long term use. So far I find them excellent. This is convenient as they can be charged from a wall charger, car charger or external power bank.
I can only recommend these batteries.

The batteries make a good impression. They feel good to the touch and the casing is not as sticky as with some other third-party batteries.
They are charged in their own charging cradle, which is operated via USB-C or Micro.
Both batteries can be operated at the same time.
In the test, one battery in my R10 lasts a good 1 hour and 15 minutes with a 4K25fps recording. My original Canon batteries do not reach these values, but they are also a bit older and only have 1040mAh. The Canon batteries last just over an hour.
It is important to remember that the K&F batteries, like all third-party batteries, do not have a status display of the battery charge in the camera. If you want this luxury, you will have to use Canon's own batteries. With the K&F (and other third-party batteries) the status display remains full until the camera simply switches off. Then the battery is also empty, of course.
I am happy with this battery set. Simply because the battery case is much more stable than my old third-party batteries. The charging cradle also seems well made.
As a cheap alternative (compared to Canon batteries) it is definitely worth considering. The only disadvantage is the missing battery status display mentioned above.

The batteries work like the OEM batteries in the H2s and X-T4. They can be charged in the cameras, which is great. The charger has a USB-C connector. The combination of these two features guarantees that you can charge these batteries wherever you can charge your phone. Great for travel. From a usability point of view, I don't feel the differences between these and the OEM devices. They work great in my Fuji cameras.

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.

I have a canon eos 250D, charge to "wake up" the batteries and have a 100% charge level, no error message when putting it in the device. Battery level present on the canon, so very satisfied with my purchase, very good brand that sells good quality photo products. To be seen over time.
