| Jan 9, 2019 at 20:07 | comment | added | QuickishFM | @YoungUn I think that USB 3.X uses 5 extra pins (see any SS (usb3.x) port, you'll see the 5 small pins before the 4 main ones) so it can send a larger current, as well as data. Because of this though, both the power adapter (or computer), cable, AND device have to be USB 3.X compatible. Essentially, the protocol is as high as the lowest component - the device and adapters need the extra pins, and the cable needs the extra wires for it. However, the smartphone might actually support USB 3.X,though I'm not sure it can make use of larger currents, you might have to look at the official documents | |
