Using K&F Concept, it was easy to find the right product for my Nikon. The product offered is a cut above the competition – especially the capacity of the battery. Combined with a speedy delivery, I do not believe it can be beaten!

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.

While these might not be the highest capacity batteries I've used, I have found that all of my EN-EL15 batteries have relatively poor life. These batteries work as expected in my Nikon Z6 and I'm happy to have a couple of extra spares I can have on hand now.

I got these as backup batteries for when I travel in rather remote areas of south America, these are very good, almost as good as the original. They charge up in the same time and hold their charge well, very good purchase.

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 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.

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.
