K&F CONCEPT 2-Pack 2600mAh NP-FZ100 Battery, USB C A7iii Batteries with 2.5H Fast Charging Compatible with Sony A7iv A6700 A7Cii A7 A6600 FX30 FX3 A9 A1 ZV-E1 Cameras

Charge quickly, last just as long as the official batteries. Both of mine are working great. Absolutely recommend as an alternative.

I really like these batteries. The built-in USB-C charging is very useful, meaning you don't need a great load of dedicated battery chargers.I have been using these, as well as the older brown version, for quite a while now. I've had no problems using them in an EOS 80D, 6D Mk II, or R5, and they seem to be holding up pretty well to daily use.

I use these with my Canon R6 II.Cool white colour makes them easy to pick out and the in built USB C charging option makes them easy to re-charge when on location.The battery level indicator seems to work ok and whilst I’ve noticed a couple of odd things on start up, they seem to work more or less on a par with other non Canon equivalents.They’re also significantly cheaper than Canon brand equivalents.

These are excellent replacement for the Canon LP-E6NH batteries and can even be charged inside the camera via the USB C port. But you will get 4 x faster charging by utilising the built in USB-C charging port (see pics) Not all batteries will charge inside the camera, even older Canon LP-E6 batteries won't do this. In my opinion, these are better than the Canon OE batteries because of this feature as you can use a battery bank to directly charge when out in the field to keep you shooting.They have excellent capacity and when I load 2 into my battery grip of my R5 they last all day no problem, same as 2 Canon batteries. But you can get 6 of these for the price of 2 Canon batteries making them amazing value for money.Highly recommended by me (pro photographer for over 25 years)

I'm "Canon" born and bred. Over the years, I've bought the Canon EOS 5Dmk1, 5Dmk2, 5DSr and 5Dmk4 all new and all from New York. Each time I bought a set of two, new official Canon batteries every time I bought each camera as I always use the associated battery grips for each camera. Now, some of those Canon batteries are getting tired and at some point I will buy an 'R' camera so wanted to buy descent, high power, replacement batteries. I've never really been a 3rd party equipment buyer, always opting to buy OEM gear (Canon) so this was the first time I've bought a 3rd party battery. I've heard so many horror stories of cheap Chinese rip-off versions of LP-6(+N+H) batteries, but these K&F batteries are superb! What I thought wasn't clear in the Amazon advert was, apart from charging via the USB cables, could these batteries be recharged in the official Canon charger and can they be recharged in a good quality 3rd party charger? YES, they can and they interface and operate/register with each of the listed cameras above as though you were using the official Canon batteries. I have no hesitation in recommending these cells. They are robust, reliable so-far, they don't get too warm when charging and they seem a very good quality product. They're not dirt-cheap for 3rd party batteries, but you get more than what you pay for with these......they are in a different league to other 3rd party batteries you find available and as such, they offer excellent value.

Very easy to use when travelling as don’t need a dedicated charger. To charge you just plug in the cable and it recharges, a light indicates when it has re charged.

I really wanted to like these as being able to usb-c charge them directly into the battery, without needing additional charging docks was very useful. They charge quickly and everything with them seems fine, but the battery life is very poor compared to the Sony original NP FZ100 batteries. I’d estimate around 50% worse.I’m not sure if I got a bad batch (I bought 4 and all of them are the same) as other reviews suggest they last just as long as Sony ones, but this is far from my experience. They have been returned, unfortunately.

I've been using these regularly in my Canon R5 for a while and am very happy. I haven't done any direct comparisons with the canon versions but these seem to last a good long while and it is great having the option to charge them with USB C. I'd definitely buy them again if I need any more batteries.
