These batteries provide good power for my Nikon and charge easily with the included charger. The price is reasonable for lithium-ion batteries. I'm glad I ordered them. If I have problems with this I will update the review.

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.

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.

I was looking for replacement batteries for my Sony camera and decided on this set from K&F Concept, which arrived well protected in a small box. At first glance I was quite satisfied, because the charger is not too big and has 2 inputs. Once USB-C, which was the current standard, and a micro-USB. A charging cable is also included, but unfortunately only micro USB.
The battery capacity with 2280mAh and 7.4V voltage is good. Offers power and runtime like the originals. In the charger, charging is indicated by a red LED and when full, it lights up green. I was also able to charge original batteries with it, which is very practical. In addition, the charger can be used to charge the device on the go, also via a power bank.
The processing is okay and the quality filled me too. All in all a good extension, because you can never have enough batteries. Because of the good price-performance ratio, I can recommend this set.
Thank you for taking the time to read my review. I hope that I was able to help a little with this, also with the photos.

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 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.

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
