Not really true. USB don't take much power to run, and currently it doesn't even support hard drives. The 15V is because it would take forever to charge at 5V. Will it charge? Yes. Even while playing Zelda? Yes, very slowly. But the official charger with PD can charge super fast while playing Zelda, and that's why you should want PD. Not for USB devices.
