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Where K&F found the outdated micro-USB connections and cables is a mystery to me.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

The two "NP-FW50" batteries that are 3/4 charged also fit in a Sony A-6400 camera and work reliably without any problems. An enclosed micro-USB cable is firmly plugged into the small charger, another USB-C connection without the supplied cable can also be used.

Especially in cold temperatures or when travelling, you are on the safe side with additional batteries that you can take with you on the go, and I think that both batteries are also safe and last a long time. There were no instructions included, but there is a "CE" mark on the batteries, the charger and the packaging.

These batteries are brilliant , in my opinion they are as good as Nikon !
i would purchase again no problem

Très bien : rapport qualité-prix par rapport au produit de marque photo. Affichage facile à lire de l'état de charge et de la situation. Les piles rechargeables conservent leur état de charge dans le temps. Je rachèterai le produit.

My main camera is a Canon 5dmkiv and I'm a big fan of backup batteries (the camera is battery hungry!) but the OEMs are extremely expensive. My current three Canon batteries are aging, I needed something new for my camera.

I have several Edelkrone motion control products that are also battery hungry and are powered by the LP-E6NH. I order third party batteries for the Edelkrone gear and that was my original intention of trying them out.

These are closer to Canon's surface than any other third party. They charge well with the included charger or Canon's. (And the included charger does a great job with the OEMs, too.)

My 5div recognized these batteries and displayed them at 100% charge and three bars of charge power (max), allows me to register them - gives the same information I get from the OEM. After checking that, I decided to actually use them to take pictures. For the first time I felt safe doing that with this camera.

I'm having a hard time doing a scientific comparison of battery life. I've used each of the K&F batteries in the camera until they were pretty depleted and they seemed to last about the same as my Canon's, maybe a little longer as those age.

So basically these are high quality alternatives to OEM products at a more attractive price point while still offering excellent performance. I would definitely order more.

Lives in my campervan, great value for money. Works a treat

I use the batteries for my Sony camera, which is getting on in years. The original batteries do not last as long and the original charger can only charge one battery.

The set here makes a good impression of workmanship. The batteries snap into the charger with a rich "click" and are charged. However, it is not the fastest charger. With a maximum of 9W via USB-C, charging takes a while. But, for this, two batteries are charged at the same time. You are very spoiled with fast chargers from today's world, but the manufacturer's specifications come close to 5V/2.1A. That is max. 10W

The batteries themselves fit well into the device and have a great capacity, especially compared to the old batteries I own. It's really fun to take several hundred photos (fast series of sports events) with one battery.

The charger itself is very small and very flexible thanks to Micro USB and USB-C. I think that's really great!

I am very satisfied with it, especially with the price/performance ratio you can be really very satisfied.

Almost the originals

This charger charges all, the included batteries and other 3rd party batteries as well as original Nikon batteries. The charging times are quite long and the batteries are charged in parallel not in sequence.
I have not done any intensive testing of the batteries but so far they seem to last long enough. I would say for the price they are excellent!

I bought these batteries to always have them with me and not run out during the photo sessions. They have a good yield and charge very quickly. It can be said that the lifespan is equal to the original batteries, at a much lower price. Absolutely recommended!
