USB Power Delivery (USB PD) is a technology that allows devices to communicate and negotiate power requirements over a USB connection. It enables faster charging by delivering higher power levels, up to 100 watts, which is beneficial for charging laptops, smartphones, and other devices more efficiently. With USB PD, devices can also share power, meaning a laptop can charge a smartphone, or vice versa. This flexibility simplifies connections and reduces the number of cables needed, making it easier to manage power needs across various devices in our daily lives.
