Usb Type C Power Delivery Laptop
This basically means that.
Usb type c power delivery laptop. Usb power delivery usb type c cable supports up to 130w of power transmission along the same cable for compatible devices compared to 2 5w on its predecessors usb 2 0 or usb 3 0. The type c connector is common to several technologies while mandating only a few of them. Some devices may have higher power capacity. Usb type c power delivery allows hp computers to deliver a higher current output at different output voltages.
The usb pd specification supported by usb c ups this power delivery to 100 watts. Usb pd or usb c power delivery is a new protocol specification that allows for faster and more flexible charging. Usb c usb pd and power delivery the usb pd specification is also closely intertwined with usb type c.
