What is dc pin?

A DC pin or DC connector (direct current connector) is an electrical cable with a plug at one end that is used to connect electronic devices or appliances to a power source. DC pins come in various sizes, shapes, and capacities, depending on the voltage and current requirement of the device or appliance. They are commonly used in electronic appliances such as laptops, routers, printers, and LED lights. Some DC pins are polarized, which means they have a positive (+) and negative (-) pin, while others are not. The DC pin is connected to the power supply, which is usually a DC adapter or a battery, and provides a continuous flow of DC power to the device or appliance.
