These are proving really useful as spare batteries for my Sony A7s. NP-FW50s are notoriously weak batteries that drain in no time, and these are pretty similar to the Sony originals, but I like the advantage of being able to charge them by USB-C. Saves me dragging another set of chargers around with me.
Though I'm really pleased with them, they really missed the boat with the USB-C port placement. If they'd put that on the bottom of the battery as it's installed in the camera, they could be charged on the go, or act a kind of dummy battery to pull in a source from something like a v-lock battery. But that's nitpicking. Good value and effective.

The thing I like the most about this battery is that I can recharge it in my car with just a USB cable; no need to take along a battery charger. It's a small thing, but I have enough trouble remembering the equipment I need for a photo safari. One less thing is helpful.
It also works well in my Fuji GFX 100S. Just like the original equipment. I can't say if it takes the same number of shots as the original, but it's close enough for me.
It arrived with a charging cable to boot. Overall, I'm pleased.

Was able to charge battery with USB C port, with camera body and with external charger. Battery life seems about the same as original battery. Highly recommended!

We are using this with our GFX 50 SII alongside two Fuji brand batteries. So far, they appear to perform the same, with one significant difference: the K&F Concept can be charged with a common charging cable. It has Type C Fast Charging, making it very convenient, especially when in the field. This is a brilliant feature. We wish all camera manufacturers would adopt this ability.

This comes in bright orange retail packaging, although the thin card box does little to protect the contents.
Inside is a pretty standard double-charger, with the addition of a USB-C charging port, and you get a USB-C to USB-A cable. Neither this nor the micro-USB offers fastcharging. The maximum you will get is 700mA when charging one battery, or 500mA per battery when charging both.
The indicator lights are fine and do the job well. The overall build quality is decent, it feels solid and doesn’t flex at all when squeezed.
The price of this is £17 (plus 10% discount via voucher), which I think is okay for what you get.

This battery is just as good as the OEM battery for photography. I can just about as many shots out of this battery on my X-H2 as i do with the OEM battery minus a handful. There is a slightly noticeable difference when running video on this battery as it gave about 20 mins less record time than the OEM. This wasn’t a scientific study and other factors may have played into the shorter runtime such as camera temp.
The white color of the battery is a nice touch to the traditional boring black batteries. This color makes your K&F battery stand out amongst the rest. The usb-c port allows for you to charge on the go without the need of a charging station.

I ordered this 2 pack of the K&F Concept 2400mAh NP-W235 Battery for my Fuji GFX100s.
When I take my GFX out for a full day of shooting, I have to take a boatload of extra batteries with me. The energy-hungry GFX uses the same low-capacity battery as the newer Fuji X-series cameras. I'm sure that the Fuji engineers chose to use this smaller battery (as compared to the battery found in the GFX50r) in order to reduce the size and weight of the 100s, but any advantage gained is, in my opinion, more than compensated for by the need to carry more batteries and a charger to charge them on.
These batteries don't need a charger. You just use the included USB-C to USB-A cord. The USB-C end plugs right into the battery and the USB-A end goes to your favorite charging block or your car's USB port. Honestly, it's a technology that deserves to be adopted by all of the camera manufacturers unless they want their clocks cleaned by the quality third-party battery distributors.
It's hard to directly compare the longevity of any battery with another, because every shoot is different. A shoot where I am using the LCD screen a lot is going to eat up battery power faster than when I rely only on the viewfinder. What I can say is that these batteries play nicely with the Fuji electronics. The camera throws no errors when using the K&F Concept batteries and properly reports their state of charge and capacity.

The NP-FW50 is a common, if not too small battery for the older line of Sony DSRL, and as such, will discharge much faster than their latest upgraded counterparts. That means a constant cycle of them is required to keep your setup (which by now, in 2023, is old), going.
This double charging dock is handy - not least for having more recent USB-C compatibility so more modern cables are compatible. There’s a snug fit for the battery to ensure maximum contact without slippage, helping to ensure minor knocks won’t cut off your charge halfway through.
Now there are some downfalls: Firstly, it’s likely you’ll need a laptop with a USB-C port handy to plug the charger into - there’s no wall adaptor, which is fair play considering we’ve lived through a generation of having wall adaptors packaged with every device sold to us, so it’s almost certain you will have one spare (or an alternative USB Micro cable lying around); but also, despite an improved USB interface, the charging voltage isn’t increased, with 700mA charging one battery still being decreased to 500mA when charging simultaneously.
This K&F’s charger form factor also shares a peculiar familiarity with my Neewer charger, down to base shape, charging display and port positioning, with the labelling for this one including double insulation logos. Reassuring, but with the other similarities, who would notice the difference.
A handy spare charger stripped back to just the basics - make sure you’ve the spare charging ports or a wall adaptor free though!
