1. Field of the Invention
The present invention generally relates to a charger, and more particularly to an AC and DC dual input charger.
2. The Related Art
A conventional charger is generally an AC power charger or a DC power charger. The AC power charger is directly connected with the AC power, and is mainly used inside a room. The DC power charger is connected with the DC power through a car charger, and is mainly used in a car and other vehicles. In order to make the charger used in both AC and DC work modes, an AC input plug and a DC input plug are provided to connect with the charger, and a manual control switch is mounted to the charger so as to switch the AC and DC input. However, when the AC and DC dual input charger described above is in use, it needs to control the switch manually to match the AC plug or DC plug so as to realize the function of charging. As a result, the usage of the AC and DC dual input charger becomes complex and apt to cause a wrong operation.
