This unit needs to be plugged into a source of power in order for it to charge your battery
Sorry, there was a problem. Please try again later.No, it must b plugged into an outlet to charge batteries. That would be nice to use as a stand-alone charger case, perhaps they will implement that idea for the next GoPro, hopefully the Hero 8.
Sorry, there was a problem. Please try again later.You can probably charge it either outlet or through any USB port but it costs only the rate of charge. If you want to charge it quick go with outlet.
Sorry, there was a problem. Please try again later.The Dual Battery Charger comes with an extra battery for your GoPro, but it does not have its own internal battery. It connects to a power supply using a USB cable, and transfers that power into your GoPro batteries. You can connect the charger to an outlet using a power plug (ex. an iPhone plug works great), or you can use other USB power sources like plugging the charger to a laptop's USB ports, or some external power packs.
