Very nice replacement or addition to the GoPro camera 10-11-12. The box comes well packaged and includes the charger, 2 batteries, and the USB cable. The batteries fit properly into the camera, I have a Hero 10 and Hero 11 which had no issues. The batteries last as long as the original and charge a bit faster. Made well they look right and work well, I can recommend this set to all Hero 10-11-12 owners.

Gopro is eating batteries extremely fast. It's always quite necessary to take as many batteries as possiple.
These K&F Concept Hero batteries for Gopro are in high quality and providing reliable power, even though it's a little bit thicker than my original one, but can fit my Gopro 10 black without any problem. I also attach here the comparison of this battery (white color) with the original battery (blue color). I also did the testing. After one hour of shooting under exactly same condition, this battery drops from 100% fully charged to 21% remaining, and the original battery drops from 100% fully charged to 6% remaining. Considering the original battery is about 2 years old. I'd say this battery is very comparable to the original one. I also attach here the comparison of this charging dock (long one) with the original charging dock (short one). But this charging dock seems not as good as the original one and not charging that fast. But it's just add-on and has 3 charging slots. No complaint. Highly recommend.

I got this for my Hero 12 and I've been very pleased so far. First, the packaging that it came in was well done, so this is giftable, in my opinion. I already have a multi-charger but this works just as well....it doesn't hurt to have a back up. These batteries perform well and appear to be similar quality to the battery that came with my Hero 12. All in all, this seems to be a solid battery/charger set....very happy with this purchase!

What I liked:

• Fit GoPro hero 12 seamlessly.
• Good battery capacity 1730mAh and two batteries included. I will not run out batteries for a day trip.
• Charge up reasonably fast.
• A charger is included which is very helpful for charging up to 3 batteries simultaneously.
• Multiple safety features as stated.

In overall, the build quality seems to be good. The charger with three channels is awesome to charge 3 batteries at the same time, instead of charging through GoPro camera one battery at a time. It allows me to have two extra backup batteries on a trip.

This K&F Concept GoPro Battery and Charger Kit is a great solution for any GoPro user looking to extend the battery life of their cameras while saving money. Here is my detailed review after testing it:

Design and Compatibility
The kit includes two "enduro" type batteries compatible with the GoPro Hero 9, 10, 11, and 12. Each battery has a capacity of 1730 mAh, slightly higher than the original batteries, and is equipped with a smart chip to ensure reliable performance.

3 Slot Charger
The included charger can charge up to three batteries simultaneously, which is extremely convenient for heavy users. It supports both USB-C and micro-USB for maximum flexibility when charging.

Performance
I found the batteries to provide comparable battery life to the original GoPro batteries. They charge quickly when connected with a good USB-C cable and a suitable charger (minimum 5V 2.1A). The charger indicates the charging status with a red light during charging and green once it is finished, which is very practical to know when the batteries are ready to be used.

Use and Transport
Compact and lightweight, this charger is easy to carry in a backpack or bag, ideal for travel and outdoor adventures. It even plugs into a USB port on a motorcycle, which adds to its versatility.

In conclusion:

The quality is good.✔
I am satisfied.

I highly recommend them, they are as efficient as the official batteries, the charger is great, it fits in my bag, it even plugs into my USB port on my motorcycle if necessary. I am very happy with them. The price is very affordable.

GoPro batteries and charger Compliant, for Hero 12, 11, 10, and 9.
With the same voltage 3.85V and 1730mAh.
The charger works well with the red indicator when charging, and green when the battery is charged, works independently with each battery.
The price is correct.

Perfectly compatible with my GoPro HERO (10).
No miracle with the autonomy, identical to the original batteries.

Very practical 3-slot charger for recharging in series after an outing!

Charger for GoPro 9/10/11/12.
Includes 2 standard batteries as well as the charger, which was stated but I didn't really take that on board as it makes this even better than just a charger.

Light weight, compact so good for traveling.

Great to prepare batteries for quick change over whilst you’re out having fun.

3 batteries took 2.5 hours to fully charge, very pleased with this.

This set of two third party party batteries for GoPro have virtually identical specs to the original batteries (3.85V 1720 mAh 6.62Wh vs K&F concept 3.85V 1730mAh 6.7Wh - see picture attached). The charger works well with both original and third party and can charge 3 batteries at the same time - very useful during travel. The battery fits well my GoPro Hero 12, which I assume means that they will fit Hero 9-12 models as well. No issues so far using them.
