I have an a7iii purchased used with the original 2 year old battery. I purchased this set for the batteries and compact charger. My camera is on the latest firmware and I don't get any software errors as noted with some 3rd party batteries. And the battery life is great. On par with my original Sony battery. The charger is compact and I appreciate the dual USB C/ Micro USB input. Charger works equally well for the Sony cell. Highly recommend.

I have always trusted K&F Concept and even here it has not disappointed me, the only drawback it takes a while to charge the batteries, but it charges them well so far, they seem identical to the original, but with many € less excellent. alternative

Works great! The batteries hold the charge well too. However be careful you will get a small error message when you turn on your case with non-original batteries. That's all! Never had a problem with this brand, quite the contrary. I recommend!

Both the charger and the batteries work well

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.
