The K&F Concept NP-FZ100 batteries have become little superheroes for me. 2600 mAh — and I swear, sometimes these things feel like they have a bit of “friendship energy” on top of that. I don't know what K&F is packing in there, but my camera is running and running... and running.
Two batteries plus a charger — I affectionately call it my “power duo with personal gas station.” While one battery bravely does its job in the camera, the other chills comfortably in the charger and gathers strength. And the charger is so practical and compact that it takes up less space in my photo bag than my guilty conscience when I take too many photos again.
The batteries themselves look high-quality, sit perfectly in the camera and do exactly what you want: They give me the good feeling that I won't suddenly run out of energy when I'm on the move. And that is worth its weight in gold — especially during long photo tours or when you absolutely want to capture that one magical moment.
In short: These batteries have saved me several times from photographic nervous breakdowns. Strong, reliable, enduring — and I love them for that. A clear purchase recommendation for anyone who wants to do something good for their camera!

I keep leaving reviews of this company, because they keep surprising me purchase after purchase. A small box will arrive, usually branded K&F in white and orange. At the opening you will find the charging base with the LEDs that indicate the charging status, the USB-A to USB-C cable, and then, well protected, the two NP-FZ100s. I am using them with my ZV E10 M2 and they are great. The possibility of having 3 batteries is very convenient. The thing that struck me is that the two batteries have a dedicated plastic protector, to protect the connections, which are certainly the most delicate part. I repeat, this brand convinces me more and more

Very good. My a6700 perfectly recognizes large capacity batteries. It charges well and is a small charger. Totally recommended

Spectacular, every day I am freaking out more, how can it be that it lasts much longer than the original, if this product has negative reviews I don't understand it because I'm super impressed, I would buy more, but for what? Yesterday I did a 2365 photo shoot and I came home with 78% what's the point of buying more if I have a lot of battery power

Quick charging and the batteries are not significantly worse than the originals

This battery and charger set is excellent value for money.
It includes 2 NP-FZ100 batteries and a 'fast' (see below) charger for (at the time of writing) under £60. Considering an original Sony battery costs over £60 each, that's one amazing bargain.
I tried both batteries in my Sony A7IV battery grip and both registered with no issues straight out of the box with 56% charge showing.
I did not initially charge the batteries as I wanted to show in the video that they work straight away, but it's always advised to fully charge the batteries before the initial use.
The charger, when plugged in (the charger has inputs for both Type C and Micro USB, meaning you shouldn't be caught short when away from the home) flashes the LCD showing the battery capacity upwards in a charging motion style before a full charge indicator is given. I did however find that the charger took a few hours to charge the batteries, despite them already being half full. So I wouldn't say it was a 'fast' charger, more an overnight one.
The K&F batteries are both a larger capacity with the original Sony battery stating 2280mAh and the K&F is 2600mAh in capacity, so this should mean you get a few more shots of usage out of it.
