Batteries last as long as the ones that I got with my gopro and it’s nice being able to charge multiple at once!

I purchased these K&F CONCEPT batteries for use in my GoPro 9 camera. These batteries work in the GoPro 9 camera just like my other K&F CONCEPT batteries work in the GoPro 7 Black. They provide excellent run times and do not cause overheating issues I have attributed to other manufacturer batteries. I feel confident using these batteries.

I film for long hours (5-6) I needed some extra batteries for My GoPro Hero 9. I will admit, that I chose this not really because of features and description but because of how it looked. Loved the compact and boxy look, but when I received it I was more than happy with the features. Love the red light when battery is charging and green when complete, love the fact that it charges 3 batteries at a time. Its great that its USB 3 my only small issue is that the usb cable should be longer than 3 inches.

I love this little charger for my GoPro. I can store 3 fully charged batteries in it and when one needs a charge you simply throw it into the charger. It monitors each battery separately and stops charging when full capacity is reached. GoPro should have designed something like this, it is not always easy to charge a GoPro.

Nice, small, portable cube can be charged from the same USB-C cable that charges Hero devices. Charging is fast. Charge indicators appear accurate.Note that it doesn't work well on under-powered USB circuits -- so use a high-quality USB power source.

Easy to use and works great!

UPDATED REVIEWseller reached out to me and sent me a brand new set completely free to replace the faulty one. New batteries and charger work flawlessly now. Hold charge as they should and I have sero problems. Used all of them on full cycles 4 times and they are definitely on par with originals1 original GoPro battery easily outlasts 4 of those... And more.I do have 2 GoPro batteries but needed a charger. Decides to try these since reviews were promising.Unfortunately the battery life is really really bad. They might be defective. I don't know.All I know is that I used both of them from 100% to 10% life twice and the performance is the same.I was recording a 10 minutes video on my GoPro hero 9 and the battery went from 100% to 62%. Same thing with the second one. it went from 100 to 67.So basically I am looking at 30 minutes of footage MAX per battery.As a comparison while using original GoPro battery I can record over 2 hours of footage before it dies. That is not right.Also if you charge the batteries in included case, and leave them there unplugged they will discharge. This makes zero sense as the charger is also sold as travel case.To summarize.You get 2 batteries that have 25% of performance comparing to original and you get a charging dock that will discharge your batteries while you travel.This is not a good deal

I totally needed this one to hold all my batteries while I charge them and to keep the batteries all in one place while I’m traveling. The other chargers that the batteries just sit on sometimes if you bump them the battery comes loose and it doesn’t get charged. This charger is the only way to go.

Works perfectly, in a small travel size.

Pretty straight forward. It will charge one at a time via USB-C cable. Also charges the stock battery that comes from the camera manufacturer.I like the fact the charger is small enough that I can easily fit it in my camera bag without having to sacrifice space.The outside is a bit rubbery, but means it will likely take a beating if it bounced around in my bag.
