The battery is an excellent alternative to the original batteries. The workmanship and quality of the battery are impressive and it delivers reliable performance for long and demanding recording sessions.

The ability to charge the battery directly via USB-C is particularly practical, which eliminates the need to carry a separate charger and is ideal for on the go. The battery fits perfectly in the camera and shows no compatibility issues. For photographers and filmmakers who are looking for a cost-effective yet powerful solution, this battery is a clear recommendation.

I bought them for my X-Pro2 and they are perfect. I think it is a very good idea that the batteries can be charged directly via USB and not need a charger that always ends up breaking. These batteries are not expensive considering their autonomy and that they are independent from the charger, one less thing to worry about. We will see how long they last or if they fail over time. So far so good.

I recently purchased the K&F Concept 2-Pack NP-W126 NP-W126S Batteries for my Fujifilm camera and have been extremely satisfied with their performance. These batteries are perfect for my Fujifilm X100V and XS10, providing reliable power for extended photography sessions. The USB-C fast charging feature is a game-changer—charging the batteries is quick and hassle-free, which is crucial when I’m out in the field and need to top up my power without wasting time. The convenience of being able to charge both batteries at once with a USB-C cable is also a big plus.

What stood out to me was the battery life—these batteries last a surprisingly long time even during intensive use. Whether I’m shooting video or taking lots of photos, they’ve held up well. The 2-pack is perfect for ensuring I always have a backup when I’m on the go, especially during long shoots where I can’t afford to run out of power.

Overall, the K&F Concept NP-W126 batteries offer great value for anyone using Fujifilm cameras like the X100V, XS10, or XT series. They are high-quality, long-lasting, and the fast charging via USB-C is an absolute game-changer for on-the-go photographers. I’d highly recommend these batteries to anyone in need of reliable, efficient power for their Fujifilm camera.

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.

As a photographer who spends a lot of time shooting outdoors, I appreciate the convenience of having extra batteries on hand. The 1050mAh capacity provides ample power for extended shooting sessions. The USB-C charging port is a huge plus, as it eliminates the need for a separate charger. I can simply plug the batteries into my laptop or power bank for quick and easy charging. The batteries are compatible with a wide range of Fujifilm cameras, including my X100V. They fit securely in the battery compartment and provide consistent performance. The build quality is excellent, and the batteries have held up well over time.

I'm using these batteries in my FujiFilm X-100F digital camera.
Straight out of the box, both the camera and external charger report the batteries as full.
I spent 3 days with a visiting friend going around the sites, so got an opportunity to try the battery out. I shoot RAW + jpg, so there's more writing going on per shot.
The battery level doesn't appear to have changed very much at all, and compares very favourably to my original Fuji battery.
I've used K&F Concepts lens accessories in the past, so expected good quality.

In the realm of photography, having a dependable backup battery can feel like striking gold.

I purchased this K&F Concept NP-W126 set, and they have truly proven their worth. While using them in my trusty X100V on a hiking trip, I appreciated how easily they fit into the camera without any hassle.

Charging via a simple USB-C cable is a real advantage, meaning fewer chargers cluttering my travel bag. They match my camera's original batteries in performance reasonably well, although they do provide slightly less shooting time. It's not a major issue, but something to keep in mind if you're embarking on a long journey without access to a plug. Despite this, the versatility they offer by allowing battery charging without specialised blocks is very convenient.

A little note, though: while they do take their time to charge, their practicality compensates for it nicely. For the price, they're excellent additions to any Fuji photographer's kit.

This two pack of direct charging replacement 1050mAh battery with USB-C port works as expected with no any errors, they are compatible with Fujifilm X100VI, X100V, XS10, XT30, XT30 II, XT20, XE4, A5.
They looks on very solid made so they will be useful and helpful for long time.
They also has a charging indicator light, which can clearly show the charging progress.
I can easily recommended to anyone for this really reasonable price.

Absolutely love the fact that these can be independently charged via regular USB C cable. Yes there are aftermarket chargers for the W126 battery that use a USB C port but these mean that you don't have to carry a charger with you at all when your out or, just as likely, if you forget your charger you can just use a regular USB C cable and a power bank to keep things rolling. No issue with the fit and finish of these battery and so far it has been working well with the X-Pro 1 and the XT30 I have used them with. Excellent.
