USB Type-C and USB Power Delivery are exciting new technology and standards that enable customers to use a single flip-able cable to connect personal electronics and provide the fastest charging speed. If you still have no idea about these two trends, passage below will lead you to this new world of USB type-c and USB power delivery.
What is USB Type-C?
USB Type-C is a specification for a small 24-pin reversible-plug connector for USB devices and USB cabling. Nowadays this technology is applied to various products such as usb type-c cable, usb type-c adapter and usb type-c charger. The USB Type-C connectors connect to both hosts and devices, replacing various Type-B and Type-A connectors and cables with a standard meant to be future-proof. Physically, the Type-C port and connector is about the same size with Micro-B USB, this means it’s small enough to work for even the smallest devices.
Starting at 2015, Type-C USB are support to USB 3.1 with the great speed of 10Gbps and has much high power output of up to 20V(100W) and 5A.
Advantages of USB Type-C
- Small flip-able connectors that reduces the number of cables
- Supports USB 3.1 up to 10Gbps
- Supports up to 15W of power
- Supports Alternate Modes through the same port
What is USB power delivery?
The USB Power Delivery Specification enables the maximum functionality of USB by providing more flexible power delivery along with data over a single cable. Its aim is to operate with and build on the existing USB ecosystem.
Actually the current USB power delivery is not the first version. In July 2012, the USB Promoters Group announced the finalization of the USB Power Delivery (PD) specification, an extension that specifies using certified PD aware USB cables with standard USB Type-A and Type-B connectors to deliver increased power (more than 7.5 W) to devices with larger power demand. Devices can request higher currents and supply voltages from compliant hosts – up to 2 A at 5 V (for a power consumption of up to 10 W), and optionally up to 3 A or 5 A at either 12 V (36 W or 60 W) or 20 V (60 W or 100 W). In all cases, both host-to-device and device-to-host configurations are supported. Quick charge vs USB power delivery.
To understand USB power delivery specification and USB power delivery 2.0 and other terms better, you need to know history of USB power delivery.
Advantages of USB power delivery
- Single-wire protocol that enables power and data over a single cable
- Enables USB Type-C cable and connectors to deliver power up to 100W
- A cheaper, smaller solution vs other USB standards
- Supports host and peripheral solutions
To be more specific, below are some examples of USB power delivery advantage:
- Enables new higher power use cases such as USB bus powered Hard Disk Drives (HDDs) and printers. This eliminates the need for a separate power brick.
- A monitor with a supply from the wall can power, or charge, a laptop while still displaying.
- USB power bricks or chargers are able to supply power through a laptop’s USB ports.
- Laptops and USB power bricks can provide higher power to battery powered devices (not currently defined by USB).
- Battery powered devices can get increased charging current from a hub and then give it back temporarily when the user’s HDD requires to spin up.
How can the combination of USB type-c and USB power delivery affects charging and data transfer.
Many of devices on market have equipped with USB type-c technology and adapt USB type-c port, such as USB type-c cable, USB type-c charger, USB type-c laptop and power banks. Below in the video, we tested the effects that USB type-c and USB power delivery would bring with different devices. Watch the video above and get to know how amazing these two technologies are!
