Volta asserts that its upcoming 120W power brick is for "techies" and gamers as well as travelers. It combines a multi-socket "~200-country" form-factor with the gallium nitride (GaN) III tech necessary for a combined up-to-120W output via USB-C. The OEM also backs its new Travel Adapter to debut with a compact form-factor and the potential safety boost of an extra fuse.
