New USB-C Type 2.1 standard offers up to 240 W power delivery

Yesterday, Benson Leung—Google engineer and intrepid USB-C cable tester—dropped the news on Twitter that a new USB-C cable specification has been released. The new spec allows for considerably heftier charging rates between compliant USB-PD devices.

Although Leung points out that the new specification has been under development for two years, very little has changed. 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.
