Two good NP-FZ100 USB-C batteries offering a high capacity of 2600 mAh, providing good power and battery life for your Sony devices.
k&f is starting to become well-known, so we'll see how it works over time, but it's a good battery kit for now.

I've consistently found K&F Concept accessories to be reliable, and this dual battery charger kit maintains that standard. The kit includes two NP-FZ100 equivalent lithium-ion batteries, fully compatible with Sony Alpha series cameras, along with a USB Type-A to Type-C charging cable for flexible power input. The charger supports parallel charging with independent monitoring, aided by a clear LED display that tracks each battery's charge status in real time. In testing, both batteries were charged from zero to full in approximately 3 hours, delivering efficient performance suitable for on-the-go workflows. The entire set arrived well-packaged with a neat, professional presentation.

This K&F charger and battery set is essentially the exact same as the Neewer set I already own - except one key difference.
First off, the charger is small and compact, and takes either Micro USB or USB C input. Personally, I would have preferred USB C in and passthrough, but it’s not a huge issue.
The batteries are the differentiator between the K&F and Neewer sets. The former are slightly higher capacity, which was unexpected. I’ll have to get more use out of them in my Sony camera to establish whether such a small varience (16Wh vs 18 Wh) makes a real-world difference.
It’s a good set. I recommend it.

The two-pack of batteries have proven to be real workhorses for my Sony Alpha.
With 2600mAh, they offer noticeably long runtimes, which is extremely useful, especially for longer shoots or while on the go.
The build quality appears robust and high-quality; nothing rattles or feels cheap.
The charger also appears sturdy and charges the batteries reliably and relatively quickly.
In use, the batteries deliver consistent performance, without unexpected drops, and retain their capacity very well even after multiple charging cycles.
For me, they are a fair and long-lasting alternative to the original batteries.

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.

Good value battery and charger kit. The batteries perform as well as the OEM ones do. The charger charges the batteries well and features an indicator as to whether the batteries are fully charged or not. Powered by provided USB cable, which is handy as it can be charged in any wall outlet, power bank, computer etc. Good value for money over the OEM batteries.
