K&F CONCEPT EN-EL15/EN-EL15a/EN-EL15b Quick Dual Battery Charger With Micro USB & Type-C Port, for Nikon D7000, D7100, D7200, D750, D850, etc.

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.

The set of a USB charger with 2 batteries

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.

Also works for charging older batteries. When I saw this article, I had concerns about compatibility. After testing it with the batteries that came with it and my older battery, I can't tell any difference. I love that there are separate gauges for both batteries. I was always afraid of taking my charger on vacation and then losing it. Now I have a spare. I can take this charger with me and leave my original charger at home. And I can now have one battery in the camera, one in my bag for backup, and one for charging at home/in the room. Satisfied customer.

These batteries provide good power for my Nikon and charge easily with the included charger. The price is reasonable for lithium-ion batteries. I'm glad I ordered them. If I have problems with this I will update the review.

The K&F CONCEPT NP-FZ100 work without any problems in my Sony A7R IV. There are no warning messages or anything like that either.

Since I own several replica batteries, I started measuring the capacity of these. I was able to determine 1911 mAh here, which is a "medium" capacity for a replica battery. In my measurements, Sony's own battery has a capacity of 2256 mAh, which is around 18% more. Considering the price difference, totally okay!

The included charger is also very compact and works well. While this is very simple, it is also light and small, good for travel and light luggage.

The K&F CONCEPT NP-FZ100 camera battery charger was delivered quickly.
It is packaged neatly and appears to be of high quality.
However, the item description on the product page is a bit muddled and confusing. You have to look carefully at which battery you really need.

But the batteries are no worse than the originals from Sony.
They load quickly and reliably.
Of course, not much can be said about the longevity, but so far I'm really satisfied.

I was looking for replacement batteries for my Sony camera and decided on this set from K&F Concept, which arrived well protected in a small box. At first glance I was quite satisfied, because the charger is not too big and has 2 inputs. Once USB-C, which was the current standard, and a micro-USB. A charging cable is also included, but unfortunately only micro USB.

The battery capacity with 2280mAh and 7.4V voltage is good. Offers power and runtime like the originals. In the charger, charging is indicated by a red LED and when full, it lights up green. I was also able to charge original batteries with it, which is very practical. In addition, the charger can be used to charge the device on the go, also via a power bank.

The processing is okay and the quality filled me too. All in all a good extension, because you can never have enough batteries. Because of the good price-performance ratio, I can recommend this set.

Thank you for taking the time to read my review. I hope that I was able to help a little with this, also with the photos.

Just as good as OEM batteries.

As we all know, third party camera batteries can be a bit controversial as some batteries are enlarged or just fail. OEM batteries are more known for being very reliable and punctual. However, this comes at a much higher cost.

I would say these do the job and only time will tell how good they are for long term use. So far I find them excellent. This is convenient as they can be charged from a wall charger, car charger or external power bank.

I can only recommend these batteries.

The batteries work like the OEM batteries in the H2s and X-T4. They can be charged in the cameras, which is great. The charger has a USB-C connector. The combination of these two features guarantees that you can charge these batteries wherever you can charge your phone. Great for travel. From a usability point of view, I don't feel the differences between these and the OEM devices. They work great in my Fuji cameras.
