The usb type c standard is gaining rapid support by enabling small form factor easy to use connectors and cables with the ability to transmit multiple protocols and offer power delivery up to 100 w a significant improvement over the 7 5 w for previous standards.
Type c power delivery cable.
This protocol expands usb to deliver up to 100 w 20 v 5 a of power.
Usb pd negotiation lets devices create a contract to deliver the optimum power level for each application.
In july 2016 it was adopted by the iec as iec 62680 1 3.
Power delivery starts at the 5v setting and is configurable up to 20v.
Usb c power delivery with usb c charges a google pixel 2 or google pixel 2 xl up to 50 percent in 37 minutes when paired with a usb c to usb c cable.
Usb c formally known as usb type c is a 24 pin usb connector system with a rotationally symmetrical connector.
If a product features usb type c it need not necessarily.
It was developed at roughly the same time as the usb 3 1 specification.
Another point of interest regarding power delivery is that it allows for power to flow both ways with no set direction based on circuit or connection.
With usb pd usb type c ports can be either a source sink or both.
Actual results will vary.
Usb power delivery pd is a single wire protocol leveraging new usb type c standards and cables.
Usb type c is not usb 3 1 the usb type c is a connector and cable specification which can utilize usb 2 0 usb 3 0 or usb 3 1 protocols for data or power delivery.
Charge time varies with environmental factors.
