First, the longer a cable gets, the lower the voltage that will be available at the end of the cable. At some point, the voltage will be too low for the device. Also, the higher the current required at the device, the lower the voltage that will be available. So higher-current devices need shorter runs than their peers. The USB spec asks that all voltages be at least 4.75V. D…
