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

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.

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.

When the batteries arrived, I tried them out straight away.
First of all, I would like to point out that the charger that comes with it has a USB C connection.
I think that's great and I wish it was everywhere. Unfortunately, you still get disappointed with that from time to time. But not here, so everything's great.
After charging, I tried the batteries in my Canon RP. The batteries fit perfectly and the camera doesn't complain. So I can't confirm what might have happened, that the camera says the batteries are fake and then doesn't want to work. They work without any problems for me.
Compared to the original battery, these from K&F have even a little more capacity at 1250mAh compared to the original 1040mAh.
I'm satisfied.

The camera batteries from K&F Concept are a good replacement or a good addition to the original batteries from Canon. They make a good impression and fit perfectly in my Canon 760D.

I also like the charger. It can be connected to any charger, power bank or USB-A socket using the included USB cable, making it the ideal solution for on the go.

My conclusion: The charger with the two camera batteries from K&F Concept is a good choice if you need additional batteries or replacements for the original batteries. I'm happy to give it five stars for that.

This is a kit consisting of a battery charger with 2 LP-E17 type replacement batteries.
The battery capacity is 1250 Mah
It comes with a USB A to USB C cord.
It also accepts a Micro USB cord

What I like:

The batteries are the exact copy of the originals.
Charging is quite fast.
The mains charger comes with a USB-C cord, so it can be charged anywhere.
At home, in the car or with a backup battery.

What I like less:

You need to have a 5V/2A USB A charger. Fast chargers are useless.

Conclusion:

It is a good compromise compared to Canon products which are more expensive.
This kit fits perfectly well, and it allows you to have more autonomy with you. Especially when you use the flash a lot.
We will see over time if the batteries have a good lifespan.

I recommend this product.
Thank you for taking the time to read my comment.
Please let me know if my comment was helpful to you. It always makes me happy.

A good little battery + charger kit for my Canon 800D.

It has 2 charging slots with an output of 8.4v - 700mA for the first Slot and 8.4v - 500mA if you charge 2 batteries at the same time. Charging is done simply by USB. (no mains socket.)

I find the charging speed fast enough for my use and the battery life seems just as good as the original ones. I also like the fact that they have a different look from the Canon batteries, it allows me not to mix them up.

In short, RAS, impeccable!
