I'm really happy with this battery set. Having spare batteries on hand is great, especially when I'm traveling and I don't know if I'll be recharging anytime soon. I love that these charge through USB, which makes it easier on the road if I do need to charge them.
So far they work just as well as my Nikon battery. I haven't done a shot count on them, but I'm sure they're fine. These batteries work in my Nikon charger, and vice versa for the Nikon batteries in this charger. You can tell they are well made and I've used other K&F Concept products before and have always liked the quality. Totally worth it!

This is the 2nd set of charger and batteries that I take with me on all my gigs and they work perfect. Just as great as the original. I have no issues what so ever. Highly recommend.

Fast charger and good batteries. I go through a lot of batteries when taking product photos because the video output is usually on so I can see lighting changes through the lens. Having a fast charger and two extra spare batteries handy makes a big difference. The battery life seems as good as anything else I have, and so far they are working well. The charger is compact, too. Being able to charge two batteries at a time instead of one as in the Nikon charger is a major plus. Altogether, a great setup and a worthwhile addition to your gear.

I like that they came with a charger, and a charger that will charge 2 batteries at the same time, with a separate indicator for both batteries! The charger is flexible, it comes ready to use USBC, or Micro USB The batteries fit perfectly in the camera, are the same rated power as my original battery, 1050 MAH. Now with two spares, there should be no worries about running out of power! The D5100 is pretty good about not eating batteries, so this should easily handle a heavy shooting day! They certainly seem like a good quality product.

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

I bought this charger with the two batteries for three reasons. Firstly, the original Nikon batteries were too expensive for me, secondly, I wanted a lightweight solution as a charger for vacation and thirdly, I have always been very satisfied with the K&F products in terms of quality and price. Unfortunately, one of the two batteries died while I was on vacation. The support team not only replaced this battery, but also gave me a new charger and an additional battery!
This is more than exemplary and I will continue to use K&F products...

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.
