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!

Perfectly suited for the t7i alarm clock.
▶️ The batteries are recognized by the case, in the settings you can see the cycles and battery voltage just like the original.
▶️ The autonomy is close to that delivered with the case.
▶️ Charger that is used with a USB-C cable, so you can charge it anywhere.

The announced capacity seems correct because the autonomy is comparable to the originals.
No compatibility issues.
On the other hand, the charger is slow, even with a QC or PD adapter it is impossible to exceed 10W (see 7-8W...)

They work well, they seem to last the same amount of time as the original, at least I don't notice any difference in practical terms.
The dual charger is also very useful!
The only thing to keep in mind is that I have a Canon RP and it seems that the camera doesn't detect the amount of battery available. It's always at 100%. I contacted Neewer support, they sent a new pack but it doesn't seem to be a defect, as the 4 batteries have the same symptoms. It doesn't prevent use at all, but for a user with specific requirements it could be a problem. I'm satisfied with both the batteries and the service and support!

Received for a few dozen days now and seems to work perfectly.
Both batteries are recognized by my camera and the battery level seems operational too.
They recharge quickly and seem to last over time.
To see in the duration of use if it holds!

Arrived quickly, they are perfect for replacing the original Canon ones.
In my experience, they were recognized without problems by a Canon EOS 800d.
At least for now, everything is ok! The duration is also superior to that of the equivalent original battery.

I recently bought a used Nikon D3300 for use with some AF-P wide angle and telephoto zoom lenses as my older DSLR D7000 will not work with any of these lenses. The OEM battery that came with the D3300 is EN-EL14a and the battery is showing its age. So I ordered these extra batteries and charger set. I really don't need two batteries as I don't use this camera often as I use my other two mirrorless FF and APS-C cameras. But those extra batteries come in handy when I take the camera on vacation and don't have to worry about charging for days.
I have purchased a number of K&F Concept products over the years and they have all been of excellent quality. Those batteries and charger also look great. It came with a charger, two batteries and a generous 3ft charging cable with USB-A and USB-C end connectors. Note, however, that a wall charger is not included in the box. The charger has USB-C and Micro-USB input ports. The batteries were delivered fully charged. The charger works fine, but it has yet to be determined how long it takes to charge either or both dead batteries.
Just like the OEM battery, these batteries can be easily inserted and removed from the camera. Works as expected. These batteries should last a while. One day I'll update this review for the number of shots I get on each full charge. I am happy with this set and given the past history of the products I have owned from K&F Concept I would definitely recommend this set.

I use the batteries in an EOS M6 Mark II and am happy with it so far.
In addition to the charger and the two batteries, the box also contains a suitable USB cable. The batteries are inserted vertically into the charger (a bit crunchy, but it will probably "widen out" later) and then charged; an LED for each battery shows the charge level.
I haven't been able to notice any difference in the M6 (so far) compared to the standard battery. Time will tell whether it will stay that way. Otherwise, everything is tip-top.
