I recently purchased a GoPro Hero 9 Black with two OEM batteries and this K&F CONCEPT Hero 9 battery set with two batteries. I can honestly not tell the difference in battery performance between the OEM and the K&F CONCEPT batteries. The charger is very compact and works for OEM batteries as well. One thing I might note is that the blue power LED on the rear of the charger is INSANELY bright!! (See pic) Not a bad thing.. just really bright!

I like that the lights let you know when they are charged. You can charge 1,2, or 3 batteries at one time. Not very heavy duty but it works.

Batteries seem to be of the same quality as what came with my go pro. Quick charge feature is convenient. Very well made, not some cheap plastic. Fully charge indicators a plus. Very compact and good for traveling

Husband need some extra batteries for his GoPro Hero 9 and these work perfect. They work and last just as long as the name brand GoPro battery he has. Very impressed!

As I expected, seems to work just fine.2 spare batteries that fit my Hero 9, a USB to USB-C charging cord and the box itself.No problem

Battery isn’t as good as GoPro batteries but I didn’t expect them to be. Battery last about an hour and charger does it job with no issues

Love the indicator lights and how it takes up very little space. Very pleased. Works with generic and gopro official batteries perfectly for the listed model.

UPDATE: 13.10.2021I've gotten around to field testing these batteries. I like the charger, the batteries seem to make my camera do strange things. They don't last as long as I expected. When I use these batteries in the camera I have trouble using the menus, the camera seems to freeze a lot. With the GoPro batteries, the camera functions normally. There were a couple of times when I couldn't get the camera to the mode I wanted to use and lost the opportunity to film. The camera froze and I had to turn it off and on before I could get it to work. Not the best thing to happen while on vacation.I'll be using the charger a lot. The batteries I'll be suspicious of and use only in non-important controlled situations.I like the idea of charging three batteries faster than with the GoPro.I got this and put the batteries in it and charged them. I'm ready to go take some time-lapse videos. Yeah

I've test three different batteries so far. They all appear to deliver about the same level of performance. My recommendation is to have plenty of spares!

Great customer service. They reached out to replace the defective batteries I received. I haven't tried them out yet but just for the customer service they deserve an updated review.
