The Power Delivery Specification (PD) is a standard that enables faster and more efficient charging of devices through a single USB connection. It allows for higher power levels, up to 100 watts, which means that not only smartphones but also laptops and other larger devices can be charged quickly. This specification enhances the versatility of USB connections, making them suitable for a wider range of electronics. With the Power Delivery Specification, devices can negotiate power requirements, ensuring that the right amount of power is delivered based on the device's needs. This feature helps prevent overheating and improves overall charging efficiency. As a result, users benefit from quicker charging times and reduced cable clutter, as fewer types of chargers are needed for different devices.
