The GoPro HERO5 Black can be charged using USB Power Delivery but how it's charging can be confusing to the user.
Here we have the GoPro HERO5 Black charging from its USB Power Delivery based GoPro Supercharger. However, while recording is going on, the battery indicator does not show that charging is going on.
Even after over half an hour of recording, the user may think that only 1% battery charge is left on the GoPro HERO5 Black.
However, once recording has stopped, you can see that the battery actually was charging all the time to 24% and shows active charging going on.
However, once the GoPro HERO5 Black starts recording, the battery indicator stops showing that it's charging again.
