The USB Power Delivery Specification (USB PD) is a standard that can realize the maximum supply of 100W power using the USB interface. Currently, the USB PD standard is divided into 10 levels of 10W, 18W, 36W, 60W, and 100W, and the voltage is 5V, 12V, and 20V, the current is 1.5A, 2A, 3A and 5A, so flexible configuration, so that a variety of electronic devices can meet the power supply requirements through a USB cable, not only can provide power for mobile devices, and even direct power supply to notebooks and monitors , And it can achieve two-way charging, that is to say two computers with USB cable can charge each other.

The USB PD standard can support devices with different voltages of less than 100W, 5V, 12V, and 20V, and integrates the power and signals into the same line. Therefore, in addition to being able to charge mobile phones and tablets, it is also possible to give laptops and other devices that cannot be USB-enabled. Power supply for rapid charging of the drive device, Apple's new MacBook is using USB Type-C + USBPD to achieve. With the support of Google and Apple’s two giants, the USB Type-C+USBPD standard is very promising to become the future unified standard. All digital devices such as smart phones, tablet computers, and laptop computers can realize a universal charger and data cable.
