Works very well for both the batteries that came with it and my original Sony battery. The batteries have slightly less power than the original, but still perform well and haven't cut power to the camera even when they've shown as 3% on the display.

Ok , batteries definitely don’t last as long as the OEM Sony batteries but throw 2 in a battery grip and it’s not even an issue during most shoots.

Sony batteries are way over-priced so I bought these based on good reviews. They work as well as originals at a fraction of the price. I had purchased a different generic battery awhile back that also worked, but every time I started up my Sony a7iii I would get a warning message about using a non Sony battery. These K&F Concept batteries do not cause that warning to pop up. I see no reason to buy Sony batteries and charger when these K&F Concept batteries and charger work as well at a fraction of the price.

I have an a7iii purchased used with the original 2 year old battery. I purchased this set for the batteries and compact charger. My camera is on the latest firmware and I don't get any software errors as noted with some 3rd party batteries. And the battery life is great. On par with my original Sony battery. The charger is compact and I appreciate the dual USB C/ Micro USB input. Charger works equally well for the Sony cell. Highly recommend.

I have always trusted K&F Concept and even here it has not disappointed me, the only drawback it takes a while to charge the batteries, but it charges them well so far, they seem identical to the original, but with many € less excellent. alternative

Works great! The batteries hold the charge well too. However be careful you will get a small error message when you turn on your case with non-original batteries. That's all! Never had a problem with this brand, quite the contrary. I recommend!

I had already bought them years ago in another version for a different camera model. I wanted to try her trust again for 'the newcomer. ' What can I say, it reconfirms the excellent product I was used to previously. The kit consists of a 2-slot charger with light indicators, cable and two batteries. The duration is comparable to the originals, they do not suffer from the memory effect, the self-discharge over a long period of inactivity is there and is even lower than the originals. Obviously, in order to be 100% operational, they need a few charge-discharge cycles, as well as they can be influenced by cold temperatures. Overall, it's a great product to have with you.
