I've long been a fan of K&F products, and these LP-E6P batteries are no exception. They are equivalent to the new Canon LP-E6P batteries intended for newer camera models, such as the Canon R5 Mark II.

I charged one of them with the provided charger, which can accept a mini-B or USB-C connector, though it comes with only a USB-C cable. In addition, the charger can charge two batteries simultaneously. Each slot on the charger has a four-bar LED display to track the charging progress. On my initial charge, no bars were displayed. After 2 hours, 3 bars were solid, and after about 2.5 hours, the battery was full.

The charged battery fits perfectly in the battery compartment and is compatible with my 90D. In several test shots and videos, all functions on the camera were working fine. They are an excellent price for these newer models.

It's a good backup set of a pair of batteries and dual-slot charger. Works right out of the box, charges somewhat slow but holds well enough for a third-party battery. No LED display on the batteries themselves to check current capacity, but at the least you get the LED display on the charger to base it off of.

Far cheaper and better price performing than OEM for sure.

Good option for Canon R5C
Not sure how much time you can get from original LP-E6p, but with this battery recording 4.k / 23.976 I got 78 minutes.

I have several K&F Concept products and they have always surprised me with their careful presentation, design and most importantly: quality.
I expected nothing less from this charger set with two batteries for the camera models listed.
Although the first charge seemed a bit slow to me (they should have come very empty), then it charged much faster.

The batteries have a capacity of 2400 mAh which is a large capacity. It can be compared (I have put them aside in the photo) with the model of the official brand.
But the most important thing is the price. If we buy this set from the official brand, the price is totally exorbitant compared to this model. And I can attest to that because I always use these batteries. I have several and their functionality is extraordinary.
Make no mistake about it: HIGHLY recommended.

These work well on Canon R6iii. Cheaper than OEM and work fine. Charger plugs into USB A, does not come with a 110V plug.

I used the batteries in a Canon R6 Mark iii. They worked just like the original Canon battery and lasted about the same amount of time. Will they hold up over time as well? Beats me, but at 1/3 of the price I'll stick with these.

Work perfectly with my R7 and charger is good.

I was ready for disappointment, but this thing is above the highest expectations. It is affordable and does everything. Charges even old Canon batteries. I didn't compare it with the newest Canon battery, but it is at least as good. Charger feels like quality piece too. Very pleased with it

Well, my camera turns on.
But I did just try one for the first time on my R6 III and got an error message which first asked if there was a Canon logo on the battery itself and then said that it could not guarantee "performance" or camera health, but it still technically works. There is just zero communication so do not even have any idea how much charge is left.

Edit
I tried the 2nd battery and it worked perfectly. After a little while I removed it and put the original one back which I was having issues with, and it now worked. Gave back two stars.
