USB PD (USB Power Delivery Specification) is a standard that can supply up to 100W of power using USB interface. It can carry higher voltage and current. The power supply capacity is up to 100W. It is divided into 10W, 18W, 36W, 60W and 100W. The voltage is 5V, 12V and 20V; the current is 1.5A, 2A, 3A and 5A. In other words, the charger that supports the USB PD protocol can charge portable electronic devices such as mobile phones and tablet computers, and can also charge devices such as notebooks, and can change the direction of power supply at will.
According to IHS Technology, the number of smartphones using Type-C in the world will be close to 100 million units in 2016, and will reach 944 million by 2020. The USB-PD feature will be one of the biggest highlights. Therefore, the United Nations General Assembly has taken the footsteps of the market and launched a USB Type-C charging solution that complies with the USB-PD standard based on many international manufacturers.
