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.

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.

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.

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.

I waited a bit before writing this review to see if there would be any issues that crop up. Fortunately, the charger works perfectly (charges OEM Sony batteries also). The fact you can connect it to a power bank is a massive bonus for me especially when out in the woods with no AC outlet options.

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.
