Abstract: A power supply applied to an electronic device for providing power includes a transformer unit, a connector, a pulse-width modulation (PWM) control unit, and a switch unit. The connector is electrically connected with the secondary side of the transformer unit for outputting a first output voltage. The PWM control unit outputs a pulse signal with a first period. The switch unit is electrically connected between the PWM control unit and the primary side of the transformer unit. When the electronic device is connected to the power supply, the connector receives an external control signal, and the PWM control unit adjusts the pulse width of the pulse signal to a second period and transmits the pulse signal with the second period to the switch unit to control the connector to output a second output voltage to the electronic device.

Abstract: A connector module includes a first connector, a first electrode, a second connector and a second electrode. The first connector has a plug hole. The first electrode is disposed in the plug hole. The second connector has a connecting portion. A projecting area of the connecting portion is larger than that area of the plug hole. The second electrode is disposed at the connecting portion. When the connecting portion is disposed in the first connector, the first electrode contacts the second electrode and an inner wall of the plug hole restrains the connecting portion from detaching from the plug hole. An electronic device with the connector module is also disclosed herein.

Abstract: A power detection jack can be connected with a plurality of power output jacks respectively to receive different power levels. Each of the power output jacks has a first insulation element, and the lengths of the first insulation elements are different from each other. The power detection jack includes a first electrode, a second electrode and a power detection element. The first electrode is disposed inside the power detection jack. The second electrode is disposed outside the power detection jack. The power detection element is disposed between the first electrode and the second electrode. When the power detection jack is connected with one of the power output jacks, the power level provided by the power output jack is determined according to a connection state of the power detection element and the first insulation element.
