Great presentation... Nice package containing batteries and cable all packed to perfection batteries with a lifespan like the original Sony batteries... I purposely left the camera on to see how far they went, everything went smoothly until the battery was completely discharged... Very satisfied!!!!!!

I have 3 Sonys and every time I bring chargers, cables, etc.
With these batteries, which can also be charged with a USB c phone charger, the machine recognizes them well and they last as long as
the originals.

All good, it comes with its USB cable, a small LED to know that it is charging, it comes charged at 80% and works without problem. I still don't know if it will last less than the original, but it would be normal so for everything else, I wouldn't care. Just one thing K&F, to say the least, the color is horrible lol

Keep up with the originals very well, but are cheaper and can be charged with a USB-C cable without a charger. There is also a protective cover for the side with the contacts for transport.

I used this on my backpacking trip and the performance is phenomenal!
Not only it has USB C charging, it also charges faster than the original batteries.
Considering I'm in an environment without electricity, my power bank was enough to charge them a couple of times. If it's the original batteries, for some reason, it drains my power bank more.
Also, people told me that the Sony system doesn't allow other factory's batteries anymore but my camera uses it like its own, no problem at all.
I don't know about the lifespan of this battery yet because it has only been a few months, but so far it outruns the original batteries!!

I love that these charge over USB-C. It was the main reason for picking these up, along with having good experience with other K&F products. The batteries fit and work perfectly, but my Sony FX30 gives me an error message. Afterwards, I can't see the battery percentage but the camera continues to work. If you're ok with that, then this is a great battery.

I am writing after several uses and I am really very happy with these batteries. In my Sony A7iv, the usual compatibility warning that is shown with non-original batteries does NOT appear anymore! And, although not essential, it's nice to be able to charge the battery directly by connecting it to a USB-C cable without using a charger.
