Very pleased with these batteries that works great in my aging Nikon D5100 DSLR that can be picky about aftermarket batteries.
Pleased that the charger accepts USB-C charging and has big clear red / green status leds for each battery.
I’ve tried a few products from K&F concept and have been impressed with them all.
5/5 recommended

So far these batteries and charger are working properly and keeping my Sony A7 III powered up. I haven't noticed an issue with battery life yet, but its only be a few weeks.

This is a pretty decent set and a good price. Compared to the OEM, the batteries retain their charge well and charge quickly.
There is not a lot else to say about this set other than it is a good product at a good price if you need additional or replacement batteries or a charger.

One of the problems of being a photographer is the cost associated with most gear. I already sink tons of money into lenses and bodies, so I really would like to get a break on the other stuff where I can. I opted to get these batteries instead of the Sony version because the price was MUCH lower. They came charged to about 60-70%, and I popped them in the charger to get them to 100%. As normal, my A7R5 pops up a warning that 'this isn't a recognized battery', but they work great anyway. The A7R5 is a battery hog as it is, so I needed to have at least 4 extra batteries for Weddings and long sessions. These work great, and for the price, I can get more sets and have 8-10 spare batteries with me on any shoot. Doesn't seem to make sense to me to buy the official name brand batteries. One thing I did note, when you plug an official Sony battery into this charger, the charger indicator doesn't function. But if you leave it in there for a while, I do overnight, it's always 100% the next day. So, value for money, these are great.

Nothing negative to say about this charger. I should have gotten this kit instead of buying extra OEM batteries which were expensive. Was looking for something like this so I could have spare batteries always fully charged. I’m using it with my Sony Alpha 7IV. Both the charger itself and the included batteries work as expected. The camera knows no difference and works the same on either. I did not see any warnings about using third party batteries. The charger can charge two at a time and can accept either a microUSB or USB-C input. I took this charger with me on two separate trips this summer and it did not let me down as I took over 1000 photos on one trip over 9 days. I didn’t time or take note of the battery life but I didn’t notice any substantial difference between these batteries and the official ones from Sony. With a total of four batteries in my travel bag I always had enough to last throughout the day.

These batteries do a good job of powering my Nikon, they're easy to keep charged, with the included charger. They're priced fairly for lithium ion batteries. I'm glad I ordered them. If I run into any issues with them, I'll update the review.

The battery in some 10-20 charge cycles in a short time remains intact regardless of whether I leave it charging for a long time, even recording at 4k the battery lasts a good time, this product is in my cart again for the quality it has with respect to the original Sony batteries, one of the best options for replacement batteries

This K&F Concept NP-FZ100 Battery and Dual Slot Charger Set works as described. It comes packed compact with everything it's suppost to. So far battery life is acceptable but I'm noticing a slight drop in life every recharge. Will have to test more to see if the longevity last but for now it's good and takes up little space.
