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.

These batteries seem to work perfectly in my R6, I used them all day on a shoot and they didn’t give a “non canon” error code. Seem to last as long as the OEM battery.
The charger with a charge indicator is nice and also nice it works with USB-C.

These things are just like the originals, just cheaper! They charge in about the same time, they show up as LP-E6NH in camera, and they function at H+ (15fps) in my Canon R7. Definitely buy them if you need extra LP-E6NHs!

The set of a USB charger with 2 batteries

At this price I will not be judging too harshly the battery duration or how slow the charger is. Let's not kid ourselves, this is a heck of a deal. I use these together in a Neewer battery grip attached to my R5C and have yet to have any problems with them. They seem to drain relatively evenly (this is skewed a little by the way the battery grip works) and they charge up just fine. K&F make a white and gray version of this battery that is 2600mAh that I prefer, but these will do in a pinch and are great for your older cameras that aren't as battery hungry as the new mirrorless cameras. The charger itself gives you a little indication of where you are at in the charge cycle but doesn't have the percentage readout that my preferred charger has, so I don't use it often. I also didn't see a decrease in charge time when hooking the charger up to a faster charging brick. In the end, this will get you through in a pinch. There are better options out there, but for the price this will definitely get you started.

The charger is nice. It has both micro-USB and Type C USB jacks so you are more likely to have the right cord (although it comes with only 1 cord). It is very light. The lighted LCD display gives limited info on the charging status, but so do the Canon chargers. The batteries seemed to charge in about the same amount of time I'm used to. I tried the batteries in Canon R5, D5MkIV, 7DMkII and 80D cameras. All accepted the batteries without any fuss and displayed the battery information just like a Canon battery. Haven't had a chance to see how long they hold up during shooting sessions, but then my shooting sessions are so variable I don't have a good feel for how long the Canon and 3rd party batteries normally last. They all seem to do the job, and I think these will to. If so, this is a great 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 get great runtime out of these batteries. I didn't time it, but I'm shooting stills with a Canon EOS R5, and they seem to be lasting longer than most of the other batteries I have.

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.

Charger seems a bit slow but tge batteries last well and function just like the original representing great value for money.
