USB Power Delivery
An industry standard for high-wattage charging for battery-powered devices with USB-C connectors.
The USB PD standard allows for USB-C chargers that deliver up to 100 watts of power, enough to charge a large laptop relatively quickly. Smaller USB PD chargers designed for phones typically offer 30 watts, enough to charge a phone very quickly.
As an industry standard, chargers and devices compatible with USB PD are interchangeable. USB PD chargers automatically deliver the appropriate amount of power to each device. Therefore a single 60W USB PD charger (for example) can be used to charge either a laptop or a phone.
