Usb type c can support usb power delivery if the device s host controller and the cable itself support the standard.
Usb type c power delivery laptop.
The power delivery output and voltage will vary based on the capabilities of the computer or device.
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.
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.
To charge faster your pc or phone charger and cable must all support the industry standards.
Usb pd or usb c power delivery is a new protocol specification that allows for faster and more flexible charging.
What this means is that.
A pc or phone with usb type c connectors has larger power limits.
Usb c is a universal charging standard.
If the connector supports usb power delivery it can charge even faster at greater power levels.
So just because you have usb type c that does not mean you have usb pd.
Usb c usb pd and power delivery the usb pd specification is also closely intertwined with usb type c.
Some devices may have higher power capacity.
The type c connector is common to several technologies while mandating only a few of them.
This helps power devices like cellphones tablets and also charge compatible laptops or ultra books.
This power delivery pd protocol was developed along with usb c.
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.
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.
Usb c is the physical port connection.
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.
A device with a type c connector does not necessarily implement usb usb power delivery or any alternate mode.
The usb pd specification supported by usb c ups this power delivery to 100 watts.
Usb 3 2 released in september 2017 replaces the usb 3 1 standard.
