Clever twist on NP-FW50 battery: an embedded charger
Although this is the first battery I've used from them, K&F Concept is a well-respected brand for camera accessories in general, and these batteries have the clever twist that the Lithium Ion charge circuitry is built into the battery, so no charger is needed. Despite that, THESE BATTERIES HAVE A VERY COMPETITIVE PRICE -- less for these two than I paid for my first one with a built-in charger. There is a simple LED that lights red when charging and turns green when charged. The battery comes with a charging cable, but no USB power supply... which isn't a big deal; the cable is a little unusual in that the USB C end clips into the battery a bit more authoritatively rather than just smoothly sliding in.

It used to be that 3rd-party smart batteries often were recognized as "fakes" by cameras which would then refuse to operate with them, and some camera models and firmware revisions are pickier than others. Over the years, I've amassed quite a collection of NP-FW50 batteries and clones, including several rejected by my newer cameras or even by my original NEX-5 after I updated the firmware.

Incidentally, the main reason I'm still buying more NP-FW50 is that I have a fleet of Sony cameras (NEX-5, NEX-7, two A6000, A6500, A7, A7II, and two A7RII) that take this battery and about half of the batteries I have eventually (after multiple years of use) started to swell a little, which is a major danger sign for Lithium Ion batteries. If your batteries are becoming a tight fit into your camera, they are swelling too and you should properly dispose of them.

Anyway, I've tried using this battery in my Sony A7RII, which is one of the latest and presumably pickiest models taking this battery, and, happily, it seems to work identically to the Sony-branded original batteries. It's too early to say if this battery will hold charge as well as Sonys over time, but so far, so good. The battery fits the Sony cameras perfectly and has a distinctive two-color case, white on one side and gray on the other, which makes it easy to avoid confusing it with the ones that need a separate charger.

Overall, I think the concept of not needing an external charger is really good and worthy of a 5/5, although the benefit is reduced slightly by the fact that you still need to carry a USB cable to charge it. It does come with a charging cable, but it would be better if the battery itself had a pull-out USB head so you could just plug it directly into a USB power supply without the need for a cable. Unlike a very similar battery, there isn't much of a price premium for these over other non-Sony FW50 batteries that don't have a built-in charger. Thus, I very strongly recommend these...

Not a Replacement, an Upgrade.
I’ve become a fan of K&F; they have proven themselves to be a serious player in the photographic and videographic markets with professional quality accessories across a broad spectrum of the marketplace.

The K&F Concept NP-FW50 battery is a professional quality replacement for Sony’s OEM NP-FW50 battery. And it is an awesome replacement!

The Sony cameras that use the NP-FW50 battery, including the A7rII that I own, are infamous for their voracious use of battery energy. And although these K&F Concept replacement NP-FW50, rated at 1100 mAH while the Sony OEMs are rated at 1020, only have about 8% more capacity, they have a shorter charging time, a number of convenient charging options, and a longer life between charges. With its USB-C charging input, it can be charged almost anywhere and with almost any charger in use for today’s current devices that has a USB output; that includes the original Sony plugin wall charger, car chargers, power banks, your phones charger, etc. And the cost of the K&F Concept 2-pack of NP-FW50 batteries is about a third less than a single Sony OEM battery.

Included with the batteries is a USB-A to USB-C charging cable for each, with a convenient cable wrap, a nice touch. There is a charging status light on each battery that is red while charging and turns green when the battery is fully charged. In one of the batteries that I received, rather than turning green when it is fully charged, the light just goes out. Not a big deal to me since the battery showed as fully charged in the camera.

Rather than a replacement battery for the Sony OEM NP-FW50, the K&F Concept Batteries are an upgrade.

Pay more $ and get the convenience of on-board USB-C charging
TL;DR - you are paying a premium of both price and battery capacity but gaining the ultimate travel convenience of not having to bring a separate charger.

CONs:
- More expensive than other aftermarket batteries. Of course still way cheaper than Sony OEM batteries.
- slightly less battery capacity than other batteries. This makes sense since the volume of the charging components take up space that could have otherwise been battery.

PROs:
- Ultimate travel convenience of being able to charge up your batteries with the same cable that you charge your phone with.
- Comes with USB-C charging cable.

What more can you say. My old Sony Nex works with at as well as my trusty A6000. Only time will tell of its longevity.

Better than the original!!
I think these are the first batteries I've used where I truly feel that they're better than the original batteries. My Sony A7RII is notorious for having poor battery life so I always use a vertical grip with mine. It may be due to age but my Sony batteries never lasted very long and typically, by the time I take 200 shots, I'm already on my 2nd battery.

I've only had these batteries for short while but I was surprised to find that I was still on the first battery after 200 or so shots. I compared the weight and the ratings for these batteries and these weigh 5g more than the Sony ones (probably related to larger cells and usb-c charging mechanism) and are rated for 1100 mah vs 1020 mah. And with the convenience of charging these in multiple ways, whether it's via charger or usb-c, this is a no brainer purchase. So far, these have been longer lasting and better than the original. Very impressive!!

Works perfect with my A6300 and A 6400 cameras
Great Idea!!!, comes with USB-C cable for each, no more charging block!!!! Charges faster than my Sony batteries too. The batteries have a LED that lights up red while it is charging and when fully charged it turns green.

Perfect for SONY ZV-E10
These replacement batteries fit my SONY ZV-E10 perfectly. They are almost identical in dimensions to the SONY OEM and the K&F has a bit higher capacity than SONY. No error messages from the camera when in use. The big advantage with these is that you. can charge directly via USB-C making the process of recharge much easier and more convenient. This type of replacement battery pretty much lets you keep shooting all day long as long as you have an adequate power bank to continually charge these. I would never go back to batteries that do not have the ability to charge directly.

Convenient and clever alternative to needing a dedicated battery charger!
These are very convenient to travel with if you have a Sony mirrorless camera that uses their first generation Li-Ion battery. They are always needed as spares since one battery can't last all day and will only provide 300 shots. We Sony shooters know this shortcoming well. But with this design, they eliminated the need for the bulky external battery charger. It's been miniaturized into the body of the pack. Just plug in a USB-C plug into it and provide it a 5V source and it's charging. A red LED shows it's charging and it turns green when fully charged. The kit comes with the USB-A to USB-c charge cable. The battery fits my Sony a6000 and A7II perfectly. They have the same capacity as stock batteries. And you can still recharge them in a traditional charger as well. Very convenient indeed!

Nice job, K&F Concepts!

Good Battery for Travel
Works fine in my sony a6500. Charges pretty fast with usb c.

I charged it with my usb power meter and it took 7.6wh to charge and given a 95% charge efficiency that puts it around 7.2wh of capacity. Slightly lower than what's stated. But not low enough to remove a star imo.

Convenient Way to Charge When Traveling
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.

USB C Charging is a life saver
I am loving this battery! Apart from having spare batteries at hand to supplement the original one (that came with my Sony ZV-E10 which doesn't last too long), I love the ability to charge these outside the camera using USB C. I've charged it using a wall charger, a car charger and a power back in different scenarios - and it is a life (and time) saver!!

I also like the LED in each battery that is red while charging, and turns green when the battery is charged.

The battery fits my Sony camera perfectly, and the camera didn't show any warning about the battery not being original, etc.
