The K&F Concept NP-FZ100 2600mAh Battery and Charger Set comes with two 2600mAh High Capacity NP-FZ100 Batteries and a Dual-Slot LCD Charger stand. This charger stand does it right. While charging the LCD screen shows an animated battery image filling up and when it is finished it stops the animation just shows a battery image full so you can tell it it is done. Too many other chargers on the market never indicate when the batteries have a full charge. The batteries work great withe my Sony camera too. Recommended!

These batteries are a great alternative to the OEM ones. The lower price point is an obvious reason, but so far, these batteries have not triggered any warning codes on my FX30, which makes these a great choice.
I haven't noticed any big performance differences between this and my original Sony ones either. As mentioned before, I don't get any 3rd party battery warning messages popping up during the power-on cycle! And I just updated to the latest firmware on my FX30 too and so far, these batteries are working perfectly!
Overall, this is a fantastic battery set for the money. Charger works great. Everything feels quality and well-made. I also love the set includes a protective cover, one for each battery, which is great for my travels. I highly recommend it.

This K&F Concept battery and charger set is a practical and high-value accessory for any photographer using Sony cameras that take the NP-FZ100 battery. The core of this kit is the compact dual-slot charger and the two included high-capacity 2600mAh batteries.
The charger itself is the standout feature. It efficiently charges two batteries simultaneously, which is a significant time-saver and ensures you always have a spare ready for a long shoot. What makes it exceptionally versatile is the inclusion of both USB-C and Micro-USB input ports. This is a fantastic design choice, as it means I can charge the batteries with any modern phone charger, power bank, or laptop cable I already have, reducing the number of specific cables I need to carry.
The two included batteries have a 2600mAh capacity, which is slightly higher than the standard OEM batteries, offering the potential for longer shooting sessions.

I wanted some spare batteries for my Sony A6700 for a upcoming holiday and these batteries fit my camera and work well.
The charging dock works with a USB-C lead, making this ideal for use abroad. The charging dock stops charging when your battery is full, so over charging is less likely.
The charging base also lets you know when each battery is fully charged so the batteries are charged independently of each other.
The build quality is very good and this works well.

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.

Seems like a solid replacement option. However, the charging base seems to take a long time to charge the batteries. The batteries fit as a replacement and operated just fine. No issues observed with overheating or any other problems.

Price at time of review was £59 with the time-limited option of a 10% discount, so price comparable with other supplier and much cheaper than Sony OEM of course.
The batteries are supplied with clip-on covers, not something I've seen before, so grit or dirt can't get into the battery contacts. The batteries fitted fine into my Sony A7R V; I've yet to see the camera warning about performance limitations with a non-Sony battery, but can't be sure K&F have completely prevented that.
Charging rate was typical, with the charger showing LCD progress bars. I appreciate that the charger has USB-C as well as micro-USB.
All in all recommened to give spare batteries for extended usage time of a Sony camera.
