USB Power Delivery Explained

Power Delivery (PD) is a specification for handling higher power and allows a range of devices to charge quickly over a USB connection. ... Power Delivery starts at the 5V setting and is configurable up to 20V. Using a standard USB-C cable, it can handle up to 60W, and will go up to 100W using a designated EMCA cable.

How does USB power delivery work?

USB Power Delivery is delivered through a USB-C cord. This cable has a reversible tip that has no up or down configuration, so no matter which way you insert it, it will fit in the device. These cords can handle higher current and voltage than older USB cords, allowing for faster charge times.

What is USB power delivery?

USB Power Delivery (USB PD) is a relatively new fast charge standard that was introduced by the USB Implementers Forum, the creators of the USB standard. It is an industry-standard open specification that provides high-speed charging with variable voltage up to 20V using intelligent device negotiation up to 5A at 100W.

What is the difference between USB-C and USB-C PD?

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.

Are all USB-C power delivery?

Not all Type-C cables support the full range of power capabilities that USB-PD specifies, however. The major differentiation is supported current. Passive Type-C cables support up to 3A by default at any USB-PD voltage range (standard voltages for fixed sources are 5V, 12V and 20V).

Is USB-C and USB 3.1 the same?

To summarize, USB 3.1 generally refers to the latest USB data transfer standard while USB Type-C is for a new USB connector type. A USB Type-C port is not necessary to support USB 3.1 data transfer. A USB 3.1 cable is not necessary to have a Type-C connector for the cable assembly.

Is USB-c USB C faster than USB A to USB C?

A USB-C connection can charge devices up to 20 times faster than basic USB. USB-C ports support USB Power Delivery, a fast-charging standard that can deliver 100 watts of power to compatible devices.

How much power can a USB port deliver?

Most computer USB ports supply 5V of electricity with a maximum current of 0.5A. This amount of current is standard across the majority of computers and means the overall power output will be 2.5 Watts at best. Later USB designs bring that current up to 0.9A.

Are all USB-C cables the same?

No, not all USB-C cables are equal. USB-C stands for the shape and type of connector, which is the same for all USB-C cables but not all cables support the same kind of protocols and transfer speeds. To use a Thunderbolt 3 product from Akitio, a Thunderbolt 3 cable is required.
