1. A charger apparatus, comprising:

  • a housing;

    a first port supported by the housing;

    a second port supported by the housing, the second port being of a different type than the first port;

    a first circuit coupled to the first port and structured to advertise a first current at the first port;

    a second circuit coupled to the second port and structured to advertise a second current at the second port; and

    a controller, wherein the first circuit and the second circuit each receive a DC power signal generated from an AC input signal provided to the charger apparatus, and wherein the controller is structured and configured to determine whether a load current on the second circuit is above a threshold level and responsive to determining that the load current on the second circuit is above the threshold level, (i) cause the first circuit to advertise the first current at a level that is less than a maximum current level that may be advertised at the first port, and (ii) cause the second circuit to advertise the second current at a level that is equal to a maximum current level that may be advertised at the second port.
