As I understand things you can only draw 2.5W from a USB 2.0 socket - (5v * 5 units of 100mA = 2.5W)
Yet I see USB powered speakers advertised rated far in excess of this.
How is this possible ?
Will a USB powered speaker system rated at say 50W really sound louder than a system rated at 2.5W ?
Am I right in assuming the only advantage of these higher rated USB powered speaker systems is that the speakers work more efficiently, and so there is less distortion ?
