Power Delivery (PD) is a technology that allows for faster and more efficient charging of devices. It enables higher power levels to be delivered through a single cable, which can charge smartphones, laptops, and other electronics more quickly than traditional methods. PD uses a USB-C connector, making it versatile and widely compatible. This technology also supports bi-directional power flow, meaning devices can both send and receive power. For example, a laptop can charge a smartphone while being charged itself. This flexibility enhances convenience and reduces the number of cables needed for different devices.
