Power on the machine, the sound is soft, the power is good, and the quality feels good. For a brushed DC motor, the motor speed changes with the voltage. We tested its parameters at other voltages:
DC2V current: 45 MA speed: 96 rpm
DC2.4V current: 45 MA speed: 116 rpm
DC3.7V current: 48 MA speed: 178 rpm
DC4.2V current: 48 MA speed: 203 rpm
DC5V current: 50 MA speed: 241 rpm
