2-Packs 1800mAh Batteries for GoPro Hero 12 11 10 9, with USB Fast Charger and Protection Case, Perfectly Compatible with GoPro Hero 12 11 10 9 Black

This is a super nifty little charger. I use a go pro hero black 10 and it fits my battery perfect and the extras this comes with works fine with my go pro. The only thing i could complain about is the batteries it includes dont last as long as actual go pro batteries, but for a back up they are perfect. I have not experienced any substantial heating or over heating with these, even with my camera being on for several hours doing timelapses. This is a great value for your money!

These charge fast and work great on our hero 12. The batteries can die fast depending what you're using it for, videos obviously dies faster. But having the rotation of extra batteries made it so I never ran out. I bought 3 of these bundle for our trip to Puerto Rico to make sure I wouldn't run out and honestly could have just bought two. But having the 9 batteries was nice on those snorkeling days for videos. They charge fast so it was easy enough to use in a car to charge too. Had multiple in rotation and would be fully charged on everything fast.

Have had these batteries for less than a year. They will not hold a charge any more. I will put them on the charger for hours and it will show less than 20% charge or won't even power the camera on. I've charged them in the dock charger and in the camera with same results. Do not recommend

Batteries say 1800 mah and charge pretty quick out of the package. Charger shows fully charged (green light) but when installed in the go pro it only shows 44% charge. Customer service was very good. Giving a 4 star because they refunded my money and also told me to keep them. Even offered to replace them as well. Said if I waited a hr after I charged it. It would show 100%. Will try that soon. Maybe I just got a bad set. But definitely Great customer service. Great seller.

great deal for charging multiple GoPro batteries and it comes with 3.

This battery charger helped me keep all my batteries charged. Great value for the money. Nice small size for travel. Easy to use. Functions as it should .

Don’t really hold a charge very long. The charger is decent though.

This product does work with chargine the batteries, that batteries are great, because they do hold a charge when not put into any device, but I give this a 2 star, because just because you have all 3 batteries put in for charging, only 1 battery will be 100% charged, whole one of them will be at around 60% and the other one at 20%. It's a bad design for the charging part for the batteries, so I guess keeping 1 battery at a time is the best thing to do for charging these batteries. I use my GoPro a lot, so with having the charger saying all batteries are charged, but only 2 of the 3 batteries are almost dead, I can't keep recording with dead batteries. This design needs to be redesigned.
