USB Type-C is a new standard for USB cables and connectors. Compared with previous USB standards, it has many advantages, including faster data transmission speed, higher power transmission and reversible connectors. A key feature of USB Type-C is that it can manage the power transmitted to the device through the port.

USB Type-C uses a technology called Power Delivery (PD) to manage the power delivered to the device. PD allows power to be delivered at different levels according to the needs of the equipment. For example, a smartphone may only need a small amount of power to charge the battery, while a laptop may need more power to run and charge the battery at the same time.

USB Type-C also supports a function called USB power transfer profile, which allows devices to negotiate the power transferred to them. This means that the device can communicate with a power supply (such as a charger or laptop) and request specific power. The power supply can then provide the required power, which helps prevent overloading or damage to the equipment.

In addition to power management, USB Type-C also supports data transmission and video output, which makes it a common and convenient standard for various devices. With more and more devices adopting USB Type-C, we are likely to see more advanced power management functions and functions become available.
