Experience next-level charging with advanced Ga N technology. This addition to Belkin's charging family offers fast charging for your device in an exceptionally compact & convenient size. Foldable prongs make it as small as possible when not in use. Gallium nitride (Ga N) is a high-performance alternative to the traditional silicon used in charging devices. Ga N transistors produce less heat, allowing components to be closer together, which means you get a much smaller charger with all the power of a big one.
