New USB-C Type 2.1 standard


Important parts pasted below:

Yesterday news released of a new USB-C charger standard. The new spec allows for considerably heftier charging rates between compliant USB devices.

Comparing the USB-C 2.0 standard to today's 2.1 standard, the optional new Extended Power Range (EPR) specification—which bumps maximum voltage up to 48 V, sufficient to deliver 240 W at 5 A—seems to be by far the largest change. Other changes, although in development for 2 years don't seem note-worthy.

USB released the following statement:
“We also anticipate a wider range of product application developers outside of the traditional USB ecosystem to now consider standardizing on USB Type-C with USB PD power their power needs.”

Key characteristics of the USB PD 3.1 specification include:

  • A choice of three new fixed voltages: 28V (above 100W), 36V (above 140W) and 48V (above 180W) joining previously defined 5V, 9V, 15V and 20V fixed voltages.
  • A new adjustable voltage mode enabling a range from 15V to one of three maximum voltages (28V, 36V, or 48V) depending on the available power allowing the device being powered to request specific voltages to a 100 mV resolution.

I share the reddit users sentiment who comments:

"Replace the 24 pin atx connector with usb-c, Replace NEMA-5 with USB-c, Replace the trailer connector with usb-c. And the tow hitch. I want to pull my horses with a USB cable."


Here's to hoping USB-C comes to more devices!
