The charger and batteries that replace the Sony NP-FZ100 are great, and cost half as much. They fit my camera like an OEM battery and work really well. I can't imagine paying full price for a Sony battery. There's no noticeable difference.

I ordered this product for two reasons.
1. I wanted additional batteries, of course
2. I wanted an external charger.

The batteries have exactly the same power and capacity as the original battery. I have felt the same way so far and can't tell so far that these batteries run out faster.

The charger is extremely light (plasitk) and really fits quickly in your pocket, it fits in the photo bag or backpack. It has a display showing the charging status of the batteries (1-4/5 bars). You can connect the charger anywhere, it has 2 interfaces, either via a micro USB cable (included) or with a USB-C cable (not included). This is convenient, of course, since one of them usually has everyone somewhere, and even in the car above the cigarettes lighter with charger, they can be charged without any problems.

The original battery charges the same as K&F Concept's, so everything I assumed has been fulfilled.

The price is of course another extra point, considering that a single Sony battery cost around €65 and you get 2 here including a charger.

This battery pack is great, it save you quite a lot of money and totally safe for my A7S iii. It can be quickly charged up in 1-2 hours so you will never run out of supply although the battery did last me a whole week if only taking a picture with video on occasions. Say no more to doubt

Bought this for my alpha 7iv, have used the batteries without problem. Charges from empty to full takes around 2.5hr. Great to be able to charge two batteries at the same time. Batteries are slightly less long lasting than the Sony original but I would say they are 70%. For the price, I can't complaint.

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.

Two batteries for this price seems to me a great option. I have used them and I wouldn't know if there is any difference from the original. It also includes the charger, which is very useful to be able to recharge two batteries at once. Very happy with the purchase. Delivery was made on the indicated date and without any incident.

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.
