USB Power Delivery is a power supply specification that enables delivery of higher power levels (up to 100 W) than was previously possible over a USB connection.
USB Power Delivery makes it possible to supply power via a USB connection to devices not previously supported, such as PCs or displays.
Other advantages are provided as well, such as the ability to switch instantly between power feed and charging, making it possible to implement charging without wasteful heat generation.
With the widespread adoption of USB Power Delivery, a large number of high-output USB chargers have appeared on the market.
Aside from PCs and displays, the number of devices capable of power reception via USB Power Delivery is increasing and is expected to increase further in future.
