Power delivery is a technology used in power adapters and other power supplies to provide higher power output to devices. It is based on the USB Power Delivery (PD) specification, developed by the USB Implementers Forum. USB PD is a charging standard that allows a device to receive up to 100W of power and enables faster charging of devices. The technology is based on the concept of negotiated power, meaning that the device and the charger will negotiate the amount of power needed for charging. The device will draw the amount of power it needs, up to the specified maximum. This can lead to a more efficient charging process, as devices are not drawing more power than they need. In addition, USB PD is capable of communicating additional information, such as the battery level and charging status, between the device and the charger. This allows for more efficient power management and can lead to longer battery life. USB PD is currently used in many power adapters and other power supplies, such as those used for laptops and smartphones. It is also used in automotive applications and is starting to be used in industrial applications.
