   Power equals voltage times current. A USB port that draws 500 mA (0.5 A) at 5 volts is drawing 2.5 watts of power. In Bus-powered USB hubs, each USB port can supply power as well as transfer data. A self-powered hub takes its power from an external power supply unit and can therefore provide full power (up to 500 mA) to every port. Self-powered ...
