<p>A power supply adapter with zero standby power consumption comprises: one power supply adaptation circuit, one alternating current power supply connection device, a power supply shell, and a direct current power supply output device. The direct current power supply output device matches with a switch unit, so that when a direct current power supply output end is connected to electric equipment, an alternating current power supply output end of the alternating current power supply connection device and an alternating current input end of the power supply adaptation circuit are connected; when the direct current power supply output end is separated from the electric equipment, the alternating current power supply connection device and the alternating current input end of the power supply adaptation circuit are disconnected, so as to eliminate the standby power consumption.</p> |
