Want to charge your GoPro Hero 8 Black without opening up the side battery door? Need to charge it on the go? Finally - a solution! The Ulanzi G8-7 battery door seems to fit the bill. Sure, it's not entirely perfect, but it solves the main issue I have with being able to charge my GoPro while on the go. I give ya a quick run-down of the pros and cons of the G8-7 USB-C charging port door for the Hero 8 Black.
Note: This will NOT work on the Hero 5/6/7 or anything other than the GoPro Hero 8 Black.
