Usb pd or usb c power delivery is a new protocol specification that allows for faster and more flexible charging.
Usb type c power delivery laptop.
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.
Usb c is a universal charging standard.
Usb c usb pd and power delivery the usb pd specification is also closely intertwined with usb type 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.
If the connector supports usb power delivery it can charge even faster at greater power levels.
The usb c power delivery protocol is a specification that allows for more flexible and faster charging of devices.
The usb pd specification supported by usb c ups this power delivery to 100 watts.
Usb c is the physical port connection.
A device with a type c connector does not necessarily implement usb usb power delivery or any alternate mode.
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 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.
What this means is that.
Usb 3 2 released in september 2017 replaces the usb 3 1 standard.
Some devices may have higher power capacity.
The type c connector is common to several technologies while mandating only a few of them.
So just because you have usb type c that does not mean you have usb pd.
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.
This power delivery pd protocol was developed along with usb c.
This basically means that.
A pc or phone with usb type c connectors has larger power limits.
Usb type c power delivery allows hp computers to deliver a higher current output at different output voltages.
Usb type c can support usb power delivery if the device s host controller and the cable itself support the standard.
