USB has both power and data lines. This new standard can use data lines to negotiate power delivery, I believe. I'd expect will still be backwards-compatible of course. I would think the only allowable voltage would be 5V, as is currently.
- em3rgent0rdr 13y agoCorrection: the new standard will always start at 5V (for legacy purposes), but then may renegotiate the voltage (and current), according to: http://www.usb.org/developers/powerdelivery/PD_1.0_Introduction.pdf http://www.usb.org/developers/powerdelivery/PD_1.0_Introduct...
- srinivasanv 13y ago100W at 5V would be a 20A current, which is sort of high. http://www.usb.org/developers/powerdelivery/PD_1.0_Introduction.pdf http://www.usb.org/developers/powerdelivery/PD_1.0_Introduct... Page 9. There will be different voltage levels: 5V, 12V, and 20V.
