I had already bought them years ago in another version for a different camera model. I wanted to try her trust again for 'the newcomer. ' What can I say, it reconfirms the excellent product I was used to previously. The kit consists of a 2-slot charger with light indicators, cable and two batteries. The duration is comparable to the originals, they do not suffer from the memory effect, the self-discharge over a long period of inactivity is there and is even lower than the originals. Obviously, in order to be 100% operational, they need a few charge-discharge cycles, as well as they can be influenced by cold temperatures. Overall, it's a great product to have with you.

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.

I bought this mostly to get two additional batteries, but the charger itself surprised me compared to the Sony single battery charger (which plugs into the wall, this one needs a separate usb charger) and the previous 3rd party one I got (where the batteries lie flat).

A very surprising touch was cell phone style battery charging lights that give you an indication of how far along you are versus the red then green indicators on my other chargers. Definitely get this one if you are red/green color blind.

If the batteries work out as well as the other 3rd party batteries, then I'm going to be really happy!

Perfect alternative to the original battery and they work exactly as the original. Really please and charge nice and quickly.

K&F supplies a complete set for Canon.

In my case for the EOS R.

Compact and comprehensive, the set comes in solid packaging.

The battery, charger and cable make a high-quality impression.

Charging time is close to the original, you need a little longer, but it is due to the capacity.

The batteries are recognized without any problems and the camera works as it should.

Can recommend this set.

Working perfectly on my Sony A7Iv.
No error messages, put it in and good to go. Very nice value.

Great product works really well! Only slightly less battery life then the genuine Brand, would highly recommend!

This set of two NP-FZ100 battery packs and a dual charger comes with a Micro-USB-USB-A cable.
The charger is made of plastic and is well made and does not look high quality. It has two built-in LEDs, which light up green and red and provide very superficial information about the charging status.
On one side are a micro-USB and a USB-C port.
Charging is self-explanatory by connecting the included cable or your own USB-C cable and then plugging it into a USB power supply or power bank. Then the two batteries in and it charges.
The batteries are well made and work better than the charger. They fit easily into a Sony camera and are similar in performance to the dozens of other third-party batteries.
Compared to Sony batteries, they are not as good, but they are also significantly cheaper.
With the charger you can charge them reliably, but slowly. With an original from Sony it is synonymous.
And overall it's a good set, even if the charger isn't great. Reasonably priced and recommended!

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.

I am a photographer and videomaker and having a lot of batteries to cover full days of work I decided to buy these newers!
The product arrived in a day and in excellent condition.
Aesthetically the charge is very nice and intuitive with the lighting of the charge of each individual battery.
The two batteries work perfectly, the machine (Sony A7iii) never gave me reading problems.
I gave 3 stars battery life due to the simple fact that compared to the original Sony there is no comparison.
At the photographic level, the yield is very good, while at the video level the duration is reduced by a lot.
However, great product for those who use them only at the photo level and do not want to spend 90 euros of original Sony charge.
