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.

The Z5 uses the EN-EL15C but can use the B variant as well, while the charge is less than the C model I use them as backup at air shows and the set up holds nicely for up to 4,000 shots.

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

I am using K&F Concept EN-EL15C Dual Slot Charger to charge batteries for my Nikon DSLR and mirrorless cameras. I am also using the included batteries with both cameras. The website headline for this kit specifies “EN-EL15C Battery.” Nikon EN-EL15C batteries are 2280mAh/16Wh, while Nikon EN-EL15 batteries are 1900mAh/14Wh. Both battery models have the same form factor and can be used interchangeably. The EL15’s rarely run low with my DSLR, but the higher-powered EL15C’s frequently start to run low and occasionally run out of power in my mirrorless camera. The batteries included with this kit are labeled “Model: EN-EL15” with 2100mAh/15.5Wh, so power and longevity are about halfway between the EL15 and EL15C.

The kit includes a USB-A to USB-C cable but does not include a USB-A power adapter. The charger has both a USB-C port and a USB-A micro port, so batteries can potentially be charged using a cable connected to the USB-A micro port, but I did not try that option. The input power for the charger is labeled 5v/2A. USB-A power adapters are frequently only 5v/1A and possibly could charge one or both batteries, but it is very likely to get hot during the charging process – it is better and safer to use a power adapter that can provide 5 volts and at least 2 amps. The output power for the charger is 8.4V and 700mA for charging a single battery, or 8.4v and 500mA when both batteries are concurrently charged (meaning charging is faster for a single battery.) The Nikon EN-EL15C charger provides 8.4v and 1200mA for a single battery, so this charger likely charges a single battery a bit slower than the Nikon charger. That said, I generally charge batteries overnight, so charging times are not normally an issue for me.

I am a fan of K&F Concept, they make excellent products, but for me, two things keep this from being a 5-star product: A) the website specifies EN-EL15C, but the batteries have slightly less power than the Nikon EN-EL15C batteries and the charger provides less charging power then the Nikon charger; and B) the power draw for the charger is two-Amps, with no adapter provided, so you may need to purchase and USB adapter that can provide 5v/2A power. That said, there are a number of things I really like about this kit: 1) it includes two batteries; 2) it can charge two batteries at once; 3) battery charging is via a USB port, so it can be charged via a USB wall adapter, via a USB port in a car, or from a battery pack ( camping, etc.); and 4) for about the price of the Nikon charger, you get a charger PLUS two batteries – so the kit is a great deal from a price perspective.

If you are planning to use this kit with a camera that uses EN-EL15 batteries and you already have a 2-amp USB-A power adapter, this is a 5-star product. However, my main camera needs the EN-EL15C batteries, so I am rating this charger and battery set 4-stars.

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.
