Что совсем не мало, учитывая что USB 2.0 позволяет напряжение только 5 В и силу тока 0,5 А, а USB 3.0 до 5 В и 0,9 А. А максимальная мощность 4,5 ватта.<br />Кроме того теперь будет возможность изменять как силу тока, так и напряжение для питания USB устройств.<br />Техника с поддержкой USB Power Delivery может появиться на рынке уже в следующем году.
