Does USB-PD require special cable?
With up to 100W of power available, USB-C PD can even charge larger devices, like tablets and laptops. All you need is the right wall charger and USB-C cable – and leave those heavy laptop power cables at home.
Does all USB-C support PD?
It’s important to note that not all USB-C ports support USB-PD, nor will all USB-C devices charge with all USB-C chargers. However, take a look at their sequel, and you can see that USB-C has since become a near-universal standard.
Is PD cable same as USB-C?
The fundamental difference between USB Type-C and USB-PD is that USB Type-C is a new reversible USB connector with a small form factor, whereas USB-PD is a power delivery protocol that supports power delivery up to 100W.
Is USB PD better than USB-C?
USB Type-C can provide up to twice the power of the BC 1.2 specification, and USB Type-C/PD offers up to 100 watts of power. USB power delivery supports high bandwidth video and data rates through alternate modes, such as DisplayPort or Thunderbolt over the USB Type-C cable.
What is a USB-C PD charger?
USB-C Power Delivery is a fast charging technology, supported by certain iOS / Apple and Android / Google devices, that delivers much higher levels of power than standard charging. Samsung smartphones and tablets support a different fast charging technology called Qualcomm® Quick Charge™.
What’s the difference between USB Type C and USB PD?
However, care is required to select the most cost-effective solution for the application as USB Type-C and USB PD offer multiple power levels. For example, USB Type-C alone can support up to 5 volts at 3 amps (15 W), while USB Type-C with USB PD allows the ecosystem to support several power levels up to a maximum of 20 volts at 5 amps (100 W).
How does USB Power Delivery ( PD ) work?

So this makes the External device not drag any power from the PC and draw power from the external power supply based on the rating of the device. You can refer to the circuit above to make the connections.
How are USB power supplies used in design?
Fortunately, by using a range of recently introduced components, designers can take advantage of new capabilities such as reversible power delivery, power negotiation and the 100 watt power delivery to design USB power supplies that charge devices – even portable computers – safely and quickly.
