Abstract
The utility model discloses a charger, which comprises a charger body. The charger body comprises a charging interface, a charging circuit, a power plug and a switch control mechanism. The switch control mechanism is located between the charging interface and the power plug. When a charging plug is detected to be inserted into the charging interface, the switch control mechanism makes the power plug and the charging circuit conducted. The charger is then powered on. When the charging plug is detected to be pulled out, the switch control mechanism then makes the power plug and the charging circuit disconnected. Though the charger body is inserted in a power strip, the charger is not powered on. The electric energy consumption is thus reduced. The charger is further prevented from being power-on for long. The service lifetime of the charger is prolonged.
