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