Abstract
A smart switching charger and a power connection device thereof are disclosed. The smart switching charger includes a socket a plug and a DC power line. The socket is mounted to a power device to acquire electricity therefrom and includes a first contact group. The plug includes a second contact group corresponding to the first contact group. At least one of the first and second contact groups is magnetic to the first contact group attracting to the second contact group. When the first contact group attracts to the second contact group, the plug acquires electricity from the socket. The DC power line connects with the plug for transmitting electricity to electrical devices. Such configuration may obtain a reliable electrical connection between the socket and the plug through magnetic adsorption. A simple and convenient operation of connecting the socket and the plug is obtained, and lifespan of the charger is improved.
