USB 3.0 and greater specifications not only promise higher speeds, up to 10Gbps for USB 3.1, but also the ability to deliver up to 100W over USB to power your laptop, display, and printer via equipment, usually a USB hub, that supports USB Power Delivery, or USB PD, via a USB Type C connector. So far very few products appear to support it, and I could only find the Macbook and ChromeBook Pixel, and a few USB PD chargers on Amazon.
So basically in the future, the need for power supplies should decrease sharply, simplifying connections, and decreasing the cost of products and shipping since devices will only need a USB port that’s compatible with USB PD, meaning your computer, printer, and display won’t need an extra power supply as long as they consume less than 100 watts combined.
The reasons I’m writing about this today, is that completely forgot about this until I saw a video by Renesas that explains USB PD in a way easy to understand with 4 main advantages:
- One cable achieves both data communication and charging
- Simple design for the interconnections between boards
- Faster charging
- Universal charger
Beside Renesas, many other companies also provide solutions for USB PD including Microchip, Cypress, NXP, TI, and more, so I assume it’s just a question of time before more devices support USB Power Delivery.
