- barrkel 3y agoYou aren't going to get 20W of fast phone charging power out of USB 2; you get 2.5W tops. USB 3 gets you to about 5W. Meanwhile USB C goes up to 240W. You're probably never going to get that directly out of a motherboard.
- themerone 3y agoThe majority of USB C ports will never support 240W power delivery.
- gruez 3y ago>you get 2.5W tops False. USB-BC allows up to 1.5A, or 15W and doesn't require usb-c https://en.wikipedia.org/wiki/USB_hardware#USB_battery_charging https://en.wikipedia.org/wiki/USB_hardware#USB_battery_charg...
- xobs 3y agoI haven't ever seen a controller that does the BPSK modulation required for A ports. I suspect the standard was defined, but everyone just decided to do signalling over the CC pins on USB-C and ignore the USB-A standard. If you know of any controllers that implement the spec, I'm very interested in knowing part numbers! If for no other reason than as a historical curiosity.
