Facts and technological theories behind Type-C Power Delivery


Today many devices charge or get their power from USB ports contained in laptops, cars, aircraft or even wall sockets. USB has become a ubiquitous power socket for many small devices such as cell phones, MP3 players and other hand-held devices.The USB Power Delivery Specification enables the maximum functionality of USB by providing more flexible power delivery along with data over a single cable. It uses USB-C cables and connectors to deliver higher levels of power to your devices. This has two benefits: one, faster charging, and two, more power for larger devices.

USB Power Delivery offers the following features:

  1. Increased power levels from existing USB standards up to 100W.
  2. Power direction is no longer fixed. This enables the product with the power (Host or Peripheral) to provide the power.
  3. Optimize power management across multiple peripherals by allowing each device to take only the power it requires, and to get more power when required for a given application.
  4. Intelligent and flexible system level management of power via optional hub communication with the PC.
  5. Allows low power cases such as headsets to negotiate for only the power they require.

  1. Enables new higher power use cases such as USB bus powered Hard Disk Drives (HDDs) and printers. This eliminates the need for a separate power brick.
  2. A monitor with a supply from the wall can power or charge a laptop while still displaying.
  3. USB power bricks or chargers are able to supply power through a laptop’s USB ports.
  4. Laptops and USB power bricks can provide higher power to battery powered devices (not currently defined by USB).
  5. Battery powered devices can get increased charging current from a hub and then give it back temporarily when the user’s HDD requires to spin up.
