have been a photographer for over 10 years and have had almost every manufacturer on the market. And as is my usual practice, I use the original battery of the respective system once and otherwise only third-party batteries. This time, however, is the first time I have used batteries from K&F Concept and yes, what can I say? The batteries are great! I can easily get through the whole day with my Sony A7 IV and the two batteries (around 8 hours at a time) and still have some charge left. In my opinion, these batteries are in no way inferior to the original from Sony and I can give them a clear recommendation. I particularly like the fact that you can charge both batteries at the same time, which is often not the case with other third-party manufacturers.

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. One USB-C, which is the current standard, and one micro USB. A charging cable is also included, but unfortunately only micro USB. The battery capacity of 2280mAh and 7.4V voltage is good. Offers power and running time, like the originals. A red LED in the charger indicates that it is charging and when it is 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 on the go, even via a power bank. The workmanship is OK and the quality is also good. All in all a good addition, because you can never have enough batteries. Due to 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.

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.

These work as advertised. They show up as “NH” batteries in an R5, so they unlock the power features including USB charging in the case. The charger also works well but only uses conventional power even when connected to a PD power supply. So don't expect fast loading.

I have a lot of generic batteries and some fit well and some don't. Some were DOA and others were the last of my original Canon batteries. So far these feel like a winner. They charge quickly and hold a good charge.

High quality - compact - expensive - modern - 2250mAh - beautiful design - Sony battery charging set The K&F Concept battery charging set for Sony is delivered in a medium-sized plastic packaging and is well packaged. The delivery includes a charger, two batteries, a micro USB charging cable and no instructions. The battery charging set is very high quality and well made. Each battery has a storage capacity of 2250mAh. It takes 4.5 hours to fully charge the 2 batteries. If the battery is empty, it can be charged using the charger with the included micro USB charging cable. Unfortunately, no power adapter was included. Optionally, you can also connect it to a computer or laptop to charge it. It also has a USB-C input, which means you can also use a USB-C charging cable. I am happy with it. Scope of delivery: ➡️1x charger ➡️2x batteries ➡️1x micro USB charging cable Pro:

⭐⭐⭐⭐ This set of two NP-FZ100 batteries and a dual charger comes with a micro USB-USB-A cable. The charger is made of plastic and is well made, but does not appear high quality. It has two LEDs built in that light up green and red, very superficially informing you about the charge level. On one side there is a micro USB and a USB-C port. Charging is self-explanatory; you connect the included cable or your own USB-C cable and then plug it into a USB power supply or power bank. Then put the two batteries in and it charges. The batteries are well made and seem better than the charger. They fit into a Sony camera without any problems and their performance is similar to that of countless other third-party batteries. Compared to Sony batteries, they are not as good, but they are also much cheaper. You can charge them reliably but slowly with the charger. An original from Sony will also work. And overall it's a good set, even if the charger isn't particularly good. The price is still OK and I recommend it! ⭐⭐⭐⭐

The K&F CONCEPT NP-FZ100 work perfectly in my Sony A7R IV. There are no warning messages or anything like that. Since I have several replica batteries, I started to measure their capacity. I was able to determine 1911 mAh, which for a replica battery is a “medium” capacity. The Sony battery has 2256 mAh in my measurements, so about 18% more. Considering the price difference, this is completely OK! The included charger is also very compact and works well. This is very simple, but also light and small, good for travel and light luggage.
