I recently bought a used Nikon D3300 for use with some AF-P wide angle and telephoto zoom lenses as my older DSLR D7000 will not work with any of these lenses. The OEM battery that came with the D3300 is EN-EL14a and the battery is showing its age. So I ordered these extra batteries and charger set. I really don't need two batteries as I don't use this camera often as I use my other two mirrorless FF and APS-C cameras. But those extra batteries come in handy when I take the camera on vacation and don't have to worry about charging for days.

I have purchased a number of K&F Concept products over the years and they have all been of excellent quality. Those batteries and charger also look great. It came with a charger, two batteries and a generous 3ft charging cable with USB-A and USB-C end connectors. Note, however, that a wall charger is not included in the box. The charger has USB-C and Micro-USB input ports. The batteries were delivered fully charged. The charger works fine, but it has yet to be determined how long it takes to charge either or both dead batteries.

Just like the OEM battery, these batteries can be easily inserted and removed from the camera. Works as expected. These batteries should last a while. One day I'll update this review for the number of shots I get on each full charge. I am happy with this set and given the past history of the products I have owned from K&F Concept I would definitely recommend this set.

When it comes to mirrorless cameras and DSLR's, having extra batteries is paramount. I got these to use with my Nikon Z6, and am very happy with their performance so far. I found that they last just about as long as my OEM Nikon batteries do, and the fact that they come with a dual charger is a nice added bonus. They worked perfectly, and have very good build quality. The charger has built in overcurrent protection, which is great if you plug the batteries in, and forget that you did so. All in all, I have no complaints at all to this point, and would absolutely recommend them as great replacement batteries. When it comes to cameras, the more batteries you have, the better. I also find that given the quality, they are very reasonably priced. I'd absolutely recommend them.

I am very pleased with these batteries and dual charger. The charger requires a USB port to work which I guess is ok, I’d prefer it to just plug into the wall, but that’s a small issue. The batteries fit perfectly in my camera. I plugged both in and gave the batteries an overnight charge. For the past three nights I’ve been doing astrophotography with long exposures and the large screen on my Nikon Z6 turned ON virtually the entire time I’m out. I’ve used about half the capacity of one battery during that time. This is a great addition to my camera bag.

Battery says EN-EL15, I put them beside my Nikon EN-EL15C as shown in picture. The charger have no issue charging both KF battery and Nikon battery(USB C from MacBooks Pro charger). The K&F EN-EL15 can power my Z6III, as well as getting charge in my camera. Shot around 100 shots of mix low light and long exposure pictures, lost about 1 bar of battery life, pretty much what I would see with my original Nikon battery. This set is extremely good value for Z6III owner.

The set of a USB charger with 2 batteries

easy to keep in car to recharge battery on the go, and comes with 2 spare batteries, so whats not to like!

Best non Nikon batteries I've bought in the last 5-7 years. More expensive than others but charge lasts far longer than the selection of cheaper ones I've previously bought.

Batteries charge easily and work just as expected, great price too.

This K&F Concept USB rechargeable battery and charger is just what you need when you take a lot of pictures. (And it comes with two batteries.)

Today we need batteries to power many of the things we use, and as expensive as they are to buy, we often look for ways to save money without sacrificing quality. With the K&F Concept name, you can be sure that you are getting the best quality while not spending a lot of money.

This charger is for Nikon cameras that use the EN-EL14 model battery. With the USB charging station with 2 battery slots, you can charge both batteries at the same time. The charger can use either a USB-C cable (included) or a micro-USB cable (not included) to charge the batteries.

A red light indicates that the batteries are charging. When it goes out, the batteries are fully charged. (Both batteries charged in about an hour and a half.)

I'm using this with a Nikon D5600 (make sure what model your camera is) and it works perfectly. It's recognized by the camera (some aftermarket batteries won't work) and since each battery is rated at 1050mAh, you're sure to have plenty of backup power on hand.

As a dedicated photographer who relies heavily on my Nikon D850, I've always been mindful of battery life. When I discovered the K&F Concept EN-EL15 battery charger, I was initially hesitant due to its significantly lower price compared to Nikon's branded options. However, after giving it a try, I'm convinced that I made the right choice.

The K&F Concept charger has exceeded my expectations in every way. It's incredibly easy to use, and the build quality feels surprisingly sturdy for a budget-friendly product. I've been using it for several charges now, and it seems to be holding up well. The charging time is comparable to the official Nikon charger, and the batteries it charges consistently deliver excellent performance.
