The GoPro Supercharger is a practical GoPro accessory to have, allowing you to charge two USB devices at once. This charger can be used almost anywhere in the world. The GoPro Supercharger has dual USB outputs, on Type-C and the other Type-A. It is compatible with the GoPro HERO5 Black, HERO5 Session, Dual Battery Charger, and Karma Grip, and gives those GoPro products an extra boost while charging through the USB-C port. Charging times are boosted 20-70% compared to a 5 volt, 1 amp output. The USB Type-A port is compatible with most devices, including current as well as legacy GoPro equipment. This port outputs 5.1 volts at 1.5 amps. Both USB outputs on the GoPro Supercharger are simultaneously active, allowing you to charge multiple devices at once.
