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 batteries are well built and works as per the OEM batteries. I tried in my Sony A7III and it works perfectly. No sign or non-OEM warning or anything.
I like the fact that the charger comes with two ports for connecting to power source. Specially USB-C since this is going to be the standard in everything ( already in Europe). USB-C port also charges faster.
My only nitpick is that you won't know how much progress it has made when it is charging. It just goes from red to green.

I've been using Sony cameras for quite awhile now and have tried a number of different third party batteries, so when I saw K&F Concept offering their version, I thought they would be worth a try, given the K&F have been around a good while.
Of course the main issue with 3rd party batteries is whether the camera flags it as a fake every time you start using it. In this case, I am please to say that my camera booted up with no warning whatever, so these passed the primary test.
One word of warning, though, is that I've had 3rd party batteries work fine until a new firmware version is released. There has not been any new firmware for my camera recently, so I cannot speak to that issue for these batteries.
I have given these the full 5 stars because of the value they represent. For less than the price of one OEM brand name battery you get two batteries and and decent charger. In my opinion, the value makes it worth the risk of them becoming unusable at some point in the future.

Also works for charging older batteries. When I saw this article, I had concerns about compatibility. After testing it with the batteries that came with it and my older battery, I can't tell any difference. I love that there are separate gauges for both batteries. I was always afraid of taking my charger on vacation and then losing it. Now I have a spare. I can take this charger with me and leave my original charger at home. And I can now have one battery in the camera, one in my bag for backup, and one for charging at home/in the room. Satisfied customer.

The batteries come about 2/3 charged and that is what is displayed on the original Sony charger.
The included K&F charger is very basic and has just a red / green indicator light, no status level for the batteries which I would have liked to find here. From that perspective, I am not a fan of this charger, I am not able to check the battery level with it.
The batteries specs (2280mAh / Voltage: 7.4V / WH: 16.8Wh) differ slightly from the original Sony FP-Z100 batteries (2280mAh / Voltage: 7.2V / WH: 16.4Wh) -- I would have liked to see the exact same specs.
The camera (with a firmware 2.0 update) recognized the battery and its charge status is displayed on the screen.
Even with the slightly different specs, the power and endurance seem like the original batteries. I cannot offer longevity observations due to a lack of long-time use.

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 have been impressed with K&F products in general and this one is no exception. The charging station takes two forms of USB cable and has easy to see indicator lights. The charging takes the same amount of time as the OEM. The batteries operate the same as the OEM batteries. They check-out in my Sony A7r. I have included a picture comparing the two batteries front and back. The batteries appear to be manufactured well with crisp plastic molding and good contacts.

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.

Purchased this product before I went away to Poland for a car show - these batteries last forever! They really are long lasting and the charger is brilliant, good indicator as to what charge percentage the batteries are at and is really easy to use, takes micro USB and USB C I believe (sorry if I'm wrong) a must have for your Sony camera kit!

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.
