It used to work perfectly and I threw the casing out because I didn't think I would ever have trouble with it but clearly I was wrong. Anytime I plug it into my go pro it doesn't seem to turn on ( the go pro) but when I unplug it. The go pro works. When ever I plug in the bacpac a red light shines meaning that is it turned on and connected. But for some reason the battery icon doesnt work and obviously the battery doesn't seem to last Any longer than it normally would. When the bacpac is plugged into the wall it shines red but the battery icon doesn't show it even after I leave it plugged in for like 6 hour it still doesn't work.
