This is the third K&F Concept product I bought. They were all surprisingly good. I bought a flash drive for my D810, which rivals the Nikon product in terms of functionality.
This unit is great for the price. I also have a K&F Concept handle for my D810 and this unit makes it much more convenient to keep the batteries charged; all I had before was a single Nikon wall charger. I like that this charges two at a time and from any USB port.

Saved a heap of dough with this product. Definitely better than buying the batteries individually which works out more expensive with a lower capacity. Strange, but true!

Si vous disposez d'une alimentation adaptée, vous pourrez recharger 2 batteries en parallèle et assez rapidement.J'utilise principalement l'alimentation de mon iPad.

When it comes to mirrorless cameras and DSLR's, having extra batteries is paramount. I got these to use with my Nikon Z6, and am very happy with their performance so far. I found that they last just about as long as my OEM Nikon batteries do, and the fact that they come with a dual charger is a nice added bonus. They worked perfectly, and have very good build quality. The charger has built in overcurrent protection, which is great if you plug the batteries in, and forget that you did so. All in all, I have no complaints at all to this point, and would absolutely recommend them as great replacement batteries. When it comes to cameras, the more batteries you have, the better. I also find that given the quality, they are very reasonably priced. I'd absolutely recommend them.

I am very pleased with these batteries and dual charger. The charger requires a USB port to work which I guess is ok, I’d prefer it to just plug into the wall, but that’s a small issue. The batteries fit perfectly in my camera. I plugged both in and gave the batteries an overnight charge. For the past three nights I’ve been doing astrophotography with long exposures and the large screen on my Nikon Z6 turned ON virtually the entire time I’m out. I’ve used about half the capacity of one battery during that time. This is a great addition to my camera bag.

Battery says EN-EL15, I put them beside my Nikon EN-EL15C as shown in picture. The charger have no issue charging both KF battery and Nikon battery(USB C from MacBooks Pro charger). The K&F EN-EL15 can power my Z6III, as well as getting charge in my camera. Shot around 100 shots of mix low light and long exposure pictures, lost about 1 bar of battery life, pretty much what I would see with my original Nikon battery. This set is extremely good value for Z6III owner.
