A good reliable back up battery is a god-send and this is just that. It charges up via USB-C which everyone has these days so really easy to recharge, it has high capacity and most importantly it works!
It fits the camera perfectly with no errors, it's easy to recharge and it has good capacity so no complaints

Canon has a put a firmware block on these batteries. When installed in an R5ii you’ll see an error message and then the camera will not function at all.

These batteries work great! I also love the USBC charge port very convenient to charge on the go in the car. These batteries last longer than an afternoon day to night Timelapse transmission. Can’t beat the price either.

I have no idea why canon doesn’t just have usb charging like these m, but I bought 4 and left the canon batteries at home with the oversized charger.

Apart from C charging being great, battery life is much better than the Canon one!

NP-FZ100 Batteries.
I can confirm these work well with Sony A7S III and A7C II cameras, absolutely no compatibility issues and the capacity matches the original OEM ones. Having shelled out almost £400 on six original Sony batteries (which are faultless by the way, just expensive) I thought I'd give these K&F ones a try, just to have a few backup batteries in my bag - and I'm happy to report they work very well...in fact I bought 4 of them. I took advantage of the special offer and got them for less than half the price of Sony ones, which makes it even better.
I initially thought the USB-C charging port was a but gimmicky but I have to admit when all your charger slots are occupied, being able to plug directly into a power bank or a V-Lock with USB port is pretty handy.
I will still go to my OEM Sony batteries first as they have proven reliability but these K&F batts are good enough to keep along side them on long shoot days.

Tried using it and it last longer and the Canon original. The USB charging is great. May be Canon should use the same charging. The battery does not get warm or hot while charging or even if I leave it connected to the USB charging cable for 24 hours.
Will be having some major photo shoots. Will update if there are issues.
First impression really good.

I cannot speak on durability, longevity or performance even. What I can confirm is that it works very well in a Sony A7IV running firmware 3.01 with no battery warning.
K&F do have a relatively decent reputation, so I took punt on these. the plan was to confirm it was fully compatible with the Sony camera, in my case the A7IV and to return it withing return window if not. I am glad to say these are keepers for now.

This a good battery and seemed to charge in a similar time frame my to original battery. I had no problems using it and found it gave me a very similar performance to the genuine item. Just having a usb-c charging port is a fantastic idea - who doesn’t have a usb-c nowadays? More than happy to recommend this product.
