Good quality NP-FZ100 batteries and Charger from K&F Concept.
I have been using the batteries and charger for twelve weeks and so far I have had no issues.
If you are out and about using your camera having extra batteries is a must have accessory to ensure you can keep taking photos for as long as you need/want to.
The charger is nothing fancy and nor does it need to be as long as it can charge the batteries which this does very well, I like the fact that you can connect this to power bank and charge the batteries making this truly portable should you need to.
The batteries do not last as long as original Sony batteries BUT then again alternative batteries never do last as long as original ones, but they are cheaper you are getting three batteries and a charger at just a little more money than one original Sony battery. So it will comes down to what is more important to you brand and better battery life time or price I will leave that for you to decide.
Overall I am happy with the batteries & charger.

To my great surprise, the batteries once mounted on my Sony A6700, did not return any warning on the camera. For the price of an original Sony, you get 3 with charger included. A bargain.

Fast charging and a great bang for your buck of a kit. If you need food batteries and a way to charge them this is for you!

Having recently purchased a new Sony A7RV, I was looking for another battery. I came across these by K&F, and having had other products by K&F, thought I'd give them a try...especially as 3 of these these come in at almost exactly the same price as a single Sony battery.
Absolutely perfect! Despite being third party batteries, my camera (which has the latest firmware), didn't display any errors or warnings. Battery life and build quality is as good as that from Sony. I really like the triple charger as the charge for each individual battery is shown and you could potentially charge everything from a high capacity power bank if you're on the road away from mains power.
I haven't noticed any difference in shooting time - everything is absolutely on par with Sony - so I'll very happily recommend these to anyone who uses NP-FZ100 batteries.

I use these batteries in a Sony A7IV and a Sony FX3, professional photo and video cameras that require powerful and reliable batteries.
These batteries work perfectly for me, they behave like the originals, they are well made and have a duration of use similar or identical to the originals.
A great addition to this pack is the triple charger, which allows us to charge up to 3 batteries at a time. In addition, the charger shows the remaining charge for each battery, and once fully charged it turns off, thus avoiding overcharging. You can use a micro-USB or USB-C cable.
It is an excellent pack, at a very advantageous price (currently, €69.99)
HIGHLY RECOMMENDED.

For use with the Sony A7R IV camera, I got the K&F Concept 3-pack of NP-FZ100 batteries and the 3-slot charger. These battery kits have proven very useful for me over the past few months, and I am very pleased with their performance and ease of use.
The batteries appear to have good longevity in terms of how long they can discharge before needing replacement and can fire at least several hundred shots per charge, which makes these on par with Sony branded NP-FZ100 batteries in terms of capacity. I particularly appreciate the utility of a simple LED indicator on the charger that informs on the charge status of each battery slot with green meaning fully charged and red meaning charging. The fact that it’s possible to charge 3 batteries at the same time is good because these cameras drain batteries rather quickly.
The physical construction of both the batteries and charger also appears to be well-engineered – there are no cheap plastic components here. The battery tabs, for example, are nicely click-in with the camera without any possibility to wiggle. But it is even better that the kit has a car charging adapter which can be used to charge batteries in my car whenever I do not have access to an electrical outlet.
Overal for the price offered, K&F Concept offers an exceptional value with this battery kit. It is very stable for my daily use of shooting pictures and the 3 slot charger is very useful. That means I never lack power to supply all my electrical appliances within my home. Definitely the best for those who own any sony mirrorless camera.
