The usb pd specification supported by usb c ups this power delivery to 100 watts.
Usb type c power delivery laptop.
This helps power devices like cellphones tablets and also charge compatible laptops or ultra books.
What this means is that.
To charge faster your pc or phone charger and cable must all support the industry standards.
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.
That means that technically it doesn t matter what usb c charger you use it should be able to power up a laptop with a usb c charging port and power bank.
This power delivery pd protocol was developed along with usb c.
Usb c is the physical port connection.
Some laptops have one usb c port that supports the pd power delivery standard and one that doesn t because that way you can use a cheaper controller chip and only have to route the power down.
A device with a type c connector does not necessarily implement usb usb power delivery or any alternate mode.
Usb 3 2 released in september 2017 replaces the usb 3 1 standard.
It was developed concurrently with usb type c usb c which is the physical connection and it is a subset of the new usb 3 1 standards.
So just because you have usb type c that does not mean you have usb pd.
The usb c power delivery protocol is a specification that allows for more flexible and faster charging of devices.
This basically means that.
Usb type c power delivery allows hp computers to deliver a higher current output at different output voltages.
The type c connector is common to several technologies while mandating only a few of them.
A pc or phone with usb type c connectors has larger power limits.
Usb type c can support usb power delivery if the device s host controller and the cable itself support the standard.
Usb c is a universal charging standard.
Usb pd or usb c power delivery is a new protocol specification that allows for faster and more flexible charging.
The power delivery output and voltage will vary based on the capabilities of the computer or device.
Currently a usb 2 0 connection provides up to 2 5 watts of power enough to charge your phone or tablet but that s about it.
