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 bought this battery charger twice as it is so incredibly practical and I’m worried about it eventually being discontinued. All good things must come to an end as the saying goes! Simple to use- Just plug in and wait for the light to tell you when the charging is complete. Overcharge cut out is also a great function. I really like it. Charges batteries to a high capacity. Practical and robust enough for everday use!!

Love that I can charge both batteries at the same time. Supplied with a micro USB cable which offers huge universal compatibility and allows you to charge up from laptops, Android boxes, TV’s, mobile chargers, car USB jacks and more… Great charger and even better higher capacity batteries for longer usage in between charges.

Great product, convenient charger as you can charge both batteries in one go, fantastic value for money

Self-sufficient and armed only with power banks and the cigar tanner lighter in the car, I threw myself into shootings for two days from morning to evening. I'm absolutely thrilled. The charger does what it should and does it quickly and reliably; you can see at a glance which battery is full and which is still needed based on the lights. Both included batteries last almost as well as the original. In short, recommended. Especially if you don't have an outlet available between shootings. I'm annoyed that I've waited so long to make up my mind. Now I don't have to worry if one shoot after another is planned again.

In addition to being cheaper, they are better than the original ones. Not only do they charge faster, but they last longer. The originals have approximately 40 minutes of continuous recording and they last just over an hour and a half.
I bought the product more than two years ago and to this day they still have the same quality

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

Very well packaged and fully charged on arrival. Batteries operate in the Z series plus previous DSLR models.
Little light weight charger is a bonus and works fine.

This is a pretty decent set and a good price. Compared to the OEM, the batteries retain their charge well and charge quickly.

There is not a lot else to say about this set other than it is a good product at a good price if you need additional or replacement batteries or a charger.

it works and works well cant fault them
