I ordered these for additional batteries for multiple GoPros. I've used them once and they're pretty solid. While I won't compare them to the original GoPro batteries, the charging base and batteries themselves are sufficient and useful. I would say as a rough guesstimate, especially since I'e only used them once, they're about 90% as effective as the original GoPro batteries. I may have noticed a slightly lower overall battery time, but that could possibly be attributed to a multitude of factors including more usage, temperatures, etc. In the end, they're a great choice and alternative to expensive first party batteries. I love the multi charging dock as this comes in handy to reduce cord clutter and space.

These batteries have proven to be reliable for my GoPro, especially in colder climates where other batteries falter. The fast charger is a boon, keeping me ready to capture action without long downtimes. While they perform well, I keep a close eye on battery life during longer shoots.

The reliability of a battery pack during extended shoots is crucial, especially in colder climates where traditional batteries falter. My experience with this battery pack was noteworthy. Despite spending hours in chilly conditions, the battery held up impressively, powering my camera without a hitch. The charger's design is practical too, charging up to three batteries at once, which proved indispensable during back-to-back sessions. This setup not only supported my use well but did so with efficiency and ease.

Power Up & Save:
This kit includes two 1720mAh batteries, similar to GoPro's Enduro batteries. They seem to hold a good charge, and for the price, they're a great alternative. While they might not last quite as long as GoPro's official batteries, the difference isn't huge.

Triple Threat Charger:
The included 3-channel charger lets you juice up three batteries at once, with handy LED lights to show you the charging status.

I picked up this K&F Concept set of batteries and charger for my GoPro 9. Everything seems well built and the batteries fit both the GoPro and the charger well.

One of my pet peeves with the GoPro was that batteries never seen to last long. Having extras is always worthwhile. Getting two batteries in this set just doubled what I had. I can't judge the long term life of the batteries, but so far, so good.

Up to this point I did not have an external charger for my batteries, so I was just charging them in the GoPro. This meant I couldn't use the camera while charging the battery (not to it's full capability at least). That's fine overnight or if I don't need the camera for a while. Now with the additional external battery charger, I can charge drained batteries while still using the camera, and have to worry about taking a time out while I wait for batteries to charge. This in itself make the K&F Concept Battery and Charger kit worth it.

As an avid adventurer and GoPro enthusiast, having a reliable power source for my camera is essential. That's why I recently invested in the K&F Concept Battery and Charger for GoPro Hero 12, 11, 10, and 9 – and I couldn't be more satisfied with my purchase.

This package includes two 1720mAh batteries and a triple battery charger, providing me with ample power to capture all of my outdoor escapades. Whether I'm hiking, biking, or surfing, having multiple batteries ensures that I never miss a moment.

One of the standout features of this battery and charger set is its compatibility with multiple GoPro models. As a proud owner of the GoPro Hero 10, I was pleased to discover that these batteries are fully compatible with my camera, as well as the Hero 12, 11, and 9. This versatility makes them a worthwhile investment for any GoPro user.

The batteries themselves are well-built and long-lasting, providing reliable power throughout extended shooting sessions. I've been impressed by their performance in various conditions, from extreme temperatures to high-action environments.

The triple battery charger is also a convenient addition to my gear kit. Its compact design makes it easy to pack for travel, and the ability to charge three batteries simultaneously saves me time and hassle.

Overall, the K&F Concept Battery and Charger for GoPro Hero 12, 11, 10, and 9 is a must-have accessory for any GoPro enthusiast. Its reliable performance, compatibility with multiple models, and convenient triple charger make it an indispensable addition to my camera gear. Whether you're a weekend warrior or a professional filmmaker, this battery solution is sure to power up your adventure.

I have a GoPro Hero 11 and these batteries fit perfectly and last just as long or longer than the original. I've purchased aftermarket batteries for various devices in the past and was disappointed. These do not disappoint. Comes with a 3 bank charger and USB A to C cord. Good to go on this purchase if you're looking at it.

K&F Concept Battery and Charger kit for GoPro is a very good deal. You receive 2 batteries and a 3-slot charger for just slightly more than GoPro charges for a single battery.

The charger lets you charge 3 GoPro batteries simultaneously, comes with a USB-A to USB-C power cable for the charger, and can also be powered by a micro-USB cable. A nice feature of this charger that is lacking in many others is a small flexible piece of plastic in each charging slot that securely holds the batteries in place - you can shake the charger upside down and the batteries will stay in the charger.

Note that this kit does not come with the USB/AC adaptor, but everyone has many of those already!

I like that the charger uses USB power instead of an AC plug, because that means you can charge batteries from a power bank, computer, or vehicle.

These two batteries each hold a ton of power so I can film for longer without worrying about cutting my day short. It's a big upgrade from the standard batteries. Thanks to the 3-channel charger I can juice up all my batteries at once, which is amazing when I'm short on time. It charges them a bit faster than the regular charger.
