This battery works great with my Nikon Z50. I needed an extra batteries and picked this one. Not only are you able to charge via USB-C, but the price is great for this battery. No issues whatsoever and I feeling like this one last a bit longer than OEM. Price is ok, just keep an eye for the discount promotion.

Second time getting a K&F Concept battery for my cameras. This time I picked up EN-EL15C battery. No issues with my Nikon Z8, Z6 or Z7. Works just fine without any error messages. Cheaper option when buying extra batteries for the cameras. You are able to charge them with your regular charger or via USB-C which comes in handy when you already have several other products that are using USB-C like your cell phone & headphone. I am able to use this battery without issues when shooting 20 fps on my Nikon Z8. If you are in the market for something that cost less and works just as good as the OEM, this is one does it.

Doesn't have quite the stated capacity of some similar batteries (this is 1250 mAh and I have others that offer 1600 mAh) but high quality, charges well and works perfectly.
So much more convenient than the original batteries that have to be charged in the supplied charger, and no longer use those batteries at all as a result of these, especially if I want to travel light as I know I can and a USB-C lead just about anywhere.

Great USB-C chargeable battery for Nikon cameras. I'm not sure if it will work with the latest cameras with authentication chips, but it works great in my D7000; I no longer have to carry around a bulky charger with me and can just use it with any USB-C charger. Battery life also seems good. Overall a nice battery.

This battery works well. It works perfectly fine and charging the battery is super simple and convenient. I did not run into any issues with this at all.

I try to carry as little as possible - less stuff to lose/break and less weight to lug around. The new generation of batteries that include an integrated USB-C port has been a quick and easy addition to my kit. Why carry around a separate charger when I can charge the batteries directly?

I compared this K&F version of the EN-EL25 with the SmallRig and OEM Nikon versions. All work without any issue in the z50, all are the same size and weight (1.8oz), and all appear to have the same charging capacity.

I've found that over time, some third party batteries hold less of a charge than the original Nikon batteries. To be clear, that has not been the case with either this K&F or the SmallRig versions, but I also haven't used them long enough yet to where it could be an issue.

I wouldn't hesitate to recommend this battery to a friend - the convenience and weight savings of being able to recharge directly, without a separate charger, is totally worth it.

This K&F Concept EN-EL15C battery is a great alternative to the one that Nikon sells. Not only is it considerably cheaper but it also can be charged through USB-C. This is really handy as I still haven't gotten a charger yet (Z6 III doesn't come with one) and have to charge my OEM Nikon Battery inside the Z6 III via USB-C.

I had issues getting another third-party battery to work with my Z6 III but this one worked without any issues. So far, this is a good Nikon battery that I can recommend.

K&F Concept has a great reputation in the photography and content creation industries as a company that provides quality accessories at a reasonable price. The K&F Concept 2600mAh EN-EL15C Battery, charged via a USB-C cable and compatible with the Nikon Z8, Z7, Z6, Z7ii, Z6ii, Z5, D850, D810, D810A, D780, D750, D610, D500, D7500, D7200 cameras, is an inexpensive and quality alternative to the more expensive Nikon batteries.

Perhaps the biggest “selling” point of this battery is the fact that it can be charge via the included USB-C cable, meaning you can charge this battery via a charger, a computer or laptop, or even a car with a USB-C charging port. The battery has more capacity than the Nikon EN-El 15C battery (7.2V and 2600mAh, vs 7V, 2280mAh) so it should last longer for photos and video. It has various protections, including temperature, over-voltage, over-discharge, over-current, over-charger and short-circuit protection. Finally, it’s fully decoded for a number of Nikon DSLR and mirrorless cameras but not the Nikon Z f or Nikon Z6 III.

Whenever you buy third party batteries, you should also keep in mind that Nikon, or any camera company, can always release new firmware for their cameras that might affect the compatibility with third-party batteries. But they remain a good value when compared to the original battery.

I got this battery for use with my Nikon D500 and D7100 DSLR bodies.

The main attraction of this battery for me was the ability to charge directly via USB C port on the battery. And it works fantastically well. Why don't all DSLR batteries include this feature??

The battery feels robustly made in terms of construction quality.

The battery works just as well for me in both my Nikon DSLRs as the originals do. It also has a fair bit more juice built in with its 2600mAh capacity rating. There are no problems with my cameras interpreting the remaining battery levels or battery age so compatibility is good.

On the face of it, the price point may seem a little high for a 3rd party battery, however it is a good quality battery, plus the USB charging convenience and additional capacity make it good value for money in my opinion.

Love the fact that this can be charged via a regular USB cable and it is not a gimmick it performs well in the camera and getting excellent battery life so far. Very happy with it.
