An exemplary charger control circuit includes an input port having a positive terminal and a negative terminal, an electrode control circuit, and an output port having a positive terminal and a negative terminal. The input port is connected to a source of power. The output port is connected to a load. The electrode switching circuit detects the electrode polarity of the input port and the output port for selectively coupling the positive terminals and the negative terminals of the two ports, and protecting the electrical equipment.
