Type-C Power Delivery Facts and Technological Theories


Many devices today charge or obtain power using USB connections in computers, vehicles, planes, and even wall plugs. Many compact devices, such as mobile phones, MP3 players, and other hand-held devices, now use USB as a power source. The USB Power Delivery Specification facilitates USB's full functioning by allowing for more flexible power delivery as well as data transmission over a single connection. It makes use of USB-C cables and connectors to provide more power to your devices. This offers two advantages: one, it allows for faster charging, and two, it provides greater power for larger devices.

USB Power Delivery offers the following features:

  1. Increased power outputs up to 100W from existing USB specifications.
  2. The direction of power is no longer set. This allows the power-supplying product (Host or Peripheral) to do so.
  3. Optimize power management across many peripherals by allowing each device to take only the power it takes, with more power available when needed for a specific application.
  4. Power management at the system level is intelligent and adaptable, thanks to optional hub communication with the PC.
  5. Allows low-power cases like headsets to negotiate for only the amount of power they need.

  1. New higher-power use cases, such as USB bus-powered Hard Disk Drives (HDDs) and printers, are now possible. There is no longer a requirement for a separate power supply.
  2. While displaying, a monitor with a power source from the wall can power or charge a laptop.
  3. A laptop's USB ports can be used to power USB power bricks or chargers.
  4. Laptops and USB power bricks can give battery-powered devices more juice (not currently defined by USB).
  5. Battery-powered devices can take use of a hub's higher charging current and then give it back when the user's HDD needs to spin up.
