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.

Great price great kit and easy to keep in the bag

Unfortunately, the current condition of my original battery only shows condition 3. In order not to stand in the rain I bought the two batteries at a very reasonable price. For this, there was a charger, which is charged by a USB port. This will accompany me during my travels, because it takes up much less space than the original one and it can also charge two batteries in parallel. And that, if necessary, also from the car battery.

The batteries are just as good as the original in size. I had also bought batteries for another camera, which, although 100% compatibility is promised, could only be inserted into the camera body under pressure. The capacity display also works fine. As for the most important thing - the long-term functionality, of course, I can not say anything about it today.

My current conclusion: batteries and charger completely fine.

The set of a USB charger with 2 batteries

simple, cheap and it works well, enough said about that.

Very happy with this, just as good as the original and at a fraction of the price.

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.

I bought this 2xbattery and charger due to me dropping my Nikon charger from waist height and it stopped working. This kit was less than half the price of a single genuine battery from Nikon. So now I have a charger and 2 spare batteries and $50 in my pocket. Currently, the replacement battery is at 62% having taken 497 pictures. It fits perfectly in my Z6 and obviously works really well so far.

You can't charge this battery "in camera", but who cares!? The small, lightweight USB charger can be used just about anywhere.

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.

For a fraction of what the original batteries cost these really do deliver, very good value.
