Heck, I know my tablet charges over twice as fast with the USB3 cable over the USB2. Perhaps ther's something more to it?
Curious. If you check the wikipedia page on USB, you will see that there are sections talking about the standards defining power and charger adaptors over USB. For faster charging than the default, there has to be a negotiation. USB3 implements a 900 mA mode (the default is 500 mA). But there are other modes reaching up to 5A. https://en.wikipedia.org/wiki/USB#Power -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
