Looks very well made and so far works really well

In general they are good for the price they cost, I have 2 originals and these 2 generic ones, when I make a video I use the originals and when I take photos I use these from K&F, as far as possible of course.

I have a canon eos 250D, charge to "wake up" the batteries and have a 100% charge level, no error message when putting it in the device. Battery level present on the canon, so very satisfied with my purchase, very good brand that sells good quality photo products. To be seen over time.

For my Canon R10 I was looking for alternative batteries that I could use in an emergency when my original Canon batteries were empty. Since I usually get through the day with the original batteries, I didn't want to buy an expensive battery and that's how I came across the batteries from "K&F Concept".

The batteries are delivered in a cardboard box, so there is no unnecessary plastic. The delivery includes the following items:
- Charger
- USB cable type
- 2x batteries (compatible with LP-E17)

The batteries are inserted upright into the charger. This requires a bit of force at the beginning, but after charging it a few times it becomes much easier. The charging process is indicated by two LEDs. Which changes from orange to green when fully charged. The charging process is completed in an acceptable time. However, the batteries then have a slightly shorter battery life than the original batteries.

Inserting them into the camera works without any problems and the batteries fit in well. Unfortunately, the camera does not recognize the batteries correctly, so the charge level cannot be displayed correctly. This means that the camera may simply switch off at some point. You should be prepared for this and replace the battery early.

The item is relatively expensive, but overall it still costs less than an original Canon battery. I would therefore recommend buying it.

I usually read a ton a reviews beforehand I buy any new equipment and online the reviews were great for the K&F battery's. The order arrived surprisingly fast and so far they are great, from the weight of the battery to it's quality charge durability, one the best camera accessories I've bought all year!

Back then with my Canon 750D and a replacement battery I had the problem of an error message because the battery was not original. With the R8 I was afraid that it would happen again. But here everything is fine, no error message or anything else. Even the battery indicator works

Just perfect for my Canon r10, like the original batteries everything works perfectly and holds better than the original.
The battery display appears on my Canon like the original, unlike other brands, nothing to say!

In the comparison pictures, on the left is the original battery from Canon and on the right is the alternative battery. The two look more or less the same and have the same dimensions. The alternative is not meant to be charged in the Canon charger but comes with its own small charger, which can be charged anywhere with a USB C cable.

The battery is comparatively cheap but offers the same endurance as the original. Great.

I was looking for some cheap and efficient replacement batteries for my Canon 250D and I can't tell any difference from the original battery with these. They also work perfectly without the camera detecting that they are not original and the charge status is displayed correctly, which is great so I don't run out of power in the middle of a photo shoot.
The dual USB charger is super handy, especially when I'm traveling. I can charge the batteries in the car, with a power bank or directly from my laptop. The options are endless!
Compatibility is wide, as these batteries work with my Canon 200D and 750D as well. I haven't had any issues in terms of fit or performance, which shows the quality of the product.
One thing that could be improved is the lack of compatibility with the original Canon charger, but honestly, with the dual charger included, I haven't missed it.

This is a kit of 2 batteries with a charger.
The first thing I would like to point out is that the charger has both a type C input and a micro USB input. The type C is appreciated, as it allows you to travel with a single cable for all your devices. The charger can recharge two batteries at once, which speeds up the workflow.
As for the batteries, they have the same capacity as the originals, they fit perfectly, and their duration is like that of the original battery, so their performance is excellent.
I think this is an essential kit to complement the camera, as a single battery can be scarce if you go on a trip.
In short, for a little more than half the price of an original battery you get two batteries and a charger with a type C input, which I think is excellent.
