The Universal Serial Bus (USB) had its humble beginnings in the mid-1990s to standardize the connection of computer peripherals to PCs, both to communicate and to supply electric power. Today, it has become commonplace on a variety of devices and appliances, including Smartphones, Smart TVs, Automobiles and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports with speeds up to 10GB/s (with USB 3.1), as well as separate power chargers for portable devices.

The new USB Power Delivery (PD) specification takes it to the next level by delivering power ranging from 60W (3A @ 20V) to 100W (5A @ 20C) over varied cable profiles: from Type C unmarked cables to Type C electronically marked cables. This increase in supply capability adequately supports high-power consumption equipment, significantly reduces battery charging times and frees the system from AC adapters to achieve a more cable-free life.
