Easy to charge without a need for a charging dock or a separate charger. Buying a pair is great as you know you’ll always have a back up battery available. Works with PD chargers

Compared to many other, even cheaper, products like Hama, this one delivers what it promises, even after months of use. So far, it's at least as good as the original, if not better.

These are quite good.
A charging dock, which these are compatible with, is useful if you have multiple batteries. The type c port is a excellent bonus.
Capacity is noticeably better than my old original batteries. I do not have new Sony batteries to compare against, but these are more than good enough given the price and charge port.
I don't know how long these will last. I've had some truly horrid experiences with cheap lithium batteries. Here's hoping these hold up.
I have an old a6300 and have not had any warnings or notifications pop up about third party batteries, these just worked.

These may not last as long as one but they didn't cost as much as well I also like the fact these can be charged in the standard way and with usbc as well

Bought these to use on an extended trip. Really liked the USBC port and indicator light on the battery for easy charging outside the camera without needing a charger base. Over four months only had to change the battery once while in the field after some heavy usage. Otherwise, each evening I would replace the day's battery with one freshly charged the night before. As to longevity, I won't know for quite a while but so far so good.

Great replacement for the original. This battery does not require a charger, it has its own usb port. Less items to carry. Very convenient.
Battery life is great. Can’t beat the price.

I used this battery for the first time in my camera for the eclipse. It charged quickly and worked great. I love the fact that you can charge it in a traditional charging base or simply by connecting a usb-c cable to it. You can never go wrong with K&F products.

The K&F Concept FW50 Battery comes with a charging cable. The battery works well with my Sony A7s. It holds slightly less charge than most FW50s, with only 1100mAh versus 1500mAh. The convenience of charging it from a USB cable is worth the 30% difference. The battery charged about the same duration as when I charged in a cradle. It is an excellent alternative for travel because it means carrying one extra item.

I've been using the K&F Concept NP-FW50 batteries with my Sony RX10 IV, and I'm totally satisfied. They slot in and work just like the original batteries, no issues whatsoever. What I really appreciate is the build quality; they feel sturdy and reliable, which is exactly what I need for long shooting days.
The USB C charging feature is a massive plus for me. It's so much more convenient to plug them directly into a USB port to charge, instead of having to carry around a separate charger. It simplifies my setup and makes it easier to ensure all my batteries are charged and ready to go, no matter where I am.
