I love the fact that these just require a usb-c cable to charge. Works flawlessly with t7i. Battery life has been solid as well.

First I must say that I am a Vine reviewer and I received these K&F Concept 2-Pack LP-E17 Battery 1040mAh with USB C Fast Charging for Canon for free as part of the vine program. The Vine program was designed to generate reviews of new products at amazon. I have a a few camera and I like to have extra batteries for all of the,. This puts my total to four for my Canon Rebel T7i. I have two canon batterie sand now these two. These batteries have a feature I have never seen before, they have a Type-C charging port the LP-E17 battery. Very convenient to charge. And they charge fast. These are 1040mAh lithium battery's and they work well. And no warning message. I can recommend.

K&F is quickly rising up my best photography accessories brands list. There stuff seems to be getting better as everyone else's quality seems to be dropping.

These batteries seem well made, they have decent charge time. Being able to charge with simply a USB-C charger is a plus.

At this price, you really can't afford to pass these up.

I love having these batteries with the USB-C connectors built in. Now I can charge the batteries just with any USB-C charger. Perfect when I travel, I don’t need to bring different chargers for different batteries. These seems to be pretty good quality lasts pretty much all day on my x100vi camera.

Works!
Charging is very convenient. Via charger or via built in USB charging port.
There is LED indicator that shows RED when being charged and GREEN when fully charged.
Good battery for X100VI.
Good value at 2 pieces.
Highly recommend.

Great batteries for your Fuji X100. I like being able to use a USB C cable to charge them externally as well.

There are a lot of third party batteries available out there, and while I am definitely cautious about buying a battery from a company that I do not recognize, I do know the K&F name so these were a bit less questionable to try out - and, hey, I could always use spare batteries since these run out so quickly when out shooting photos.

These came nearly fully charged, so I was able to run them down until depleted and then charge them via the USB-C port on them. They charged quickly and without issue, and they didn't give me any trouble when using them in my cameras.

The quality looks as good as OEM, but I will say that I prefer the look of these over the OEM fuji batteries - they just look more premium to me, and the added benefit of being able to charge them via USB-C is definitely a nice upgrade (and something that I have with my other camera body batteries). These will also charge in the regular plugin style charging cradles without issue, if you prefer.

From what I can tell, there's no real difference at all between the life of these batteries as compared to OEM (meaning that they last just as long when in camera as the Fuji branded ones). In fact, other than a nicer look and extra feature, I can't tell any difference from the batteries that came with my cameras so it really is a no brainer when it comes to whether or not to get these - and it's a two pack so that's pretty sweet, too.

K&F Concept’s NP-W126 NP-W126S battery set is an essential backup for Fujifilm camera users, delivering impressive longevity and fast charging via USB-C. The batteries work seamlessly with models like the X100V, XT30 II, and XE4, maintaining a steady charge that rivals Fujifilm’s original batteries. The USB-C fast charging feature is convenient, allowing both batteries to be fully charged in just a couple of hours, perfect for on-the-go photographers.

The only minor drawback is the lack of a built-in charge level indicator on the batteries themselves, which would be helpful for quick checks. However, the high-capacity performance and rapid recharge capabilities more than make up for it. This two-pack is a must-have for extended shoots, providing peace of mind and eliminating the fear of running out of battery mid-session.

I quite like the K&F Concept line of batteries—and these NP-W126’s are no exception—because of the integrated USB C charging ports. It makes for one fewer type of charger to worry about. However, there is a price for that convenience: these batteries are rated for 7.77Wh, which is 0.97Wh less than the official Fujifilm-branded battery. All in all, on days where I’m going to be doing a lot of shooting, I’d rather carry around an extra battery than an extra charger.

This fits my Fujifilm camera perfectly and already comes fully charged, but maybe charge it again in case so it's actually at full capacity. I've never used this kind of battery before where you can charge the battery itself without the charging port. There's good and bad to both as this makes it so much easier to travel with but then at the same time you'll need multiple USB cables as you need to charge them individually. Luckily, it does come with a USB C cable each but you'll also need a charging station that allows you to put in multiple USB cables. Really cool concept and you can of course still charge it as is with the wall charger, etc. And if you're on the go, you can charge it with a portable charger. What a genius idea, never thought this was available. Another great product by K&F. Great value too.
