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