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 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.

Very practical to have spare batteries for a photo weekend! The dual slot charger is well thought out

The batteries are no different from the original battery. Same quality and more features.

Unfortunately unusable, perhaps I got a Sunday model. But 1% self-discharge per hour seems abnormal to me. Too bad, I expected more. Update: After absolutely perfect behavior from the manufacturer, I can now draw a conclusion after an extended test phase of the replacement batteries. 1 battery is completely flawless and shows what appears to be the correct percentage. The second battery has the following problem. In the camera, it shows 100-80% after just a few hours. I assume that the software is not recognizing something correctly and that the battery is also in good shape. Either it has/had something to do with the Sony A7IV software or the first two batteries were Monday models. Many thanks to K&F.

The batteries came half charged so I used the charger overnight to charge them to 100%. I then left both batteries for a few days before testing them with my Sony camera. Both batteries showed a charge of 100%.
One of my earlier third party NP FW batteries had a habit of slowly draining at about 1% per day when not in use and the camera was not in use, while another set completely failed within a year of use. This seems to hold the charge well for the time being. If I see problems I will update here.
As mentioned in the title of my review, the charger can be conveniently connected via a typical USB connector as well as a newer format (USB-C). The lights correctly indicate whether the battery is charged or not, and other brands of NP-FW50 batteries can be used.
Overall very good quality and no problems so far.

This rating refers to the LP-E6NH (Canon 5D).
I like that the charger can accept both USB-C and Micro-USB.
It comes with two 2250mA batteries (of course it's not as good as OEM).
It can charge two at the same time. The charging indicator is simple, just red (charging) and green (fully charged).
I like the portability because the original Canon charger is so big and bold and can only charge 1 battery (and no USB).
