The quality/price ratio is truly satisfactory.

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).

In general they are good for the price they cost, I have 2 originals and these 2 generic ones, when I make a video I use the originals and when I take photos I use these from K&F, as far as possible of course.

These work as advertised. They show up as “NH” batteries in an R5, so they unlock the power features including USB charging in the case. The charger also works well but only uses conventional power even when connected to a PD power supply. So don't expect fast loading.

The batteries make a good impression. They feel good to the touch and the casing is not as sticky as with some other third-party batteries.
They are charged in their own charging cradle, which is operated via USB-C or Micro.
Both batteries can be operated at the same time.

In the test, one battery in my R10 lasts a good 1 hour and 15 minutes with a 4K25fps recording. My original Canon batteries do not reach these values, but they are also a bit older and only have 1040mAh. The Canon batteries last just over an hour.

It is important to remember that the K&F batteries, like all third-party batteries, do not have a status display of the battery charge in the camera. If you want this luxury, you will have to use Canon's own batteries. With the K&F (and other third-party batteries) the status display remains full until the camera simply switches off. Then the battery is also empty, of course.

I am happy with this battery set. Simply because the battery case is much more stable than my old third-party batteries. The charging cradle also seems well made.
As a cheap alternative (compared to Canon batteries) it is definitely worth considering. The only disadvantage is the missing battery status display mentioned above.

Great for recharging the batteries of my eso r8. Perfect value for money

I have a lot of generic batteries and some fit well and some don't. Some were DOA and others were the last of my original Canon batteries. So far these feel like a winner. They charge quickly and hold a good charge.

To be honest, I dislike The En-EL14 batteries for Nikon cameras as much as i do the NP-Fw50 batteries for Sony. These batteries have always had terrible battery life in my use cases. So having multiple batteries was always a must, to ensure that i was never up a creek without a paddle when i needed it most.

K&F has always done a good job with their series of batteries. I have tested their batteries across multiple camera brands and i have never had any issues with any of them. The only thing that can be said is that these do not give you the full battery life that the OEM will offer but the reduced battery life to cost savings over the OEM is worth it in most cases for me.

I used these batteries in my Nikon D5600 and D3500. I noticed more of a difference in performance in my D5600 battery life when compared to OEM than with my D3500. I took both cameras out with me while i walked around getting shots of nature for the day. It was about 95 degrees that day so i expected the batteries to die much faster, which did not happen. The batteries held up well in the higher temps and gave me a sufficient amount of shots. In most cases, i would never take over 300 shots when birding or anything of that nature but did on both cameras just to better access the batteries.

The biggest area that i noticed a difference in was when i left the batteries fully charged in the camera bodies and coming back 2 days later to one at 52% and the other at 39% when i had never seen the at much of a power drain on my OEM batteries when i left them in the body. Not sure why that happened but i know now to never leave those batteries in the body if i want them fully charged and ready to go.

Overall these are good batteries that fall slightly short of the OEM. It is also hard to find new OEM batteries, so amongst the deep sea of third party batteries, these are some of the better ones i have used.

I have a canon eos 250D, charge to "wake up" the batteries and have a 100% charge level, no error message when putting it in the device. Battery level present on the canon, so very satisfied with my purchase, very good brand that sells good quality photo products. To be seen over time.

Very pleased with these batteries that works great in my aging Nikon D5100 DSLR that can be picky about aftermarket batteries.

Pleased that the charger accepts USB-C charging and has big clear red / green status leds for each battery.

I’ve tried a few products from K&F concept and have been impressed with them all.

5/5 recommended
