1. An apparatus comprising: at least one charger having a first node and a second node, the at least one charger configured to: accept an input voltage at the first node; and selectively: operate in a first mode to generate a first output voltage at the second node that is greater than or less than the input voltage; or operate in a second mode to generate a second output voltage at the second node that is substantially equal to the input voltage, wherein the at least one charger is further configured to: accept another input voltage at the second node; and selectively: operate in a third mode to generate a third output voltage at the first node that is greater than or less than the other input voltage; or operate in a fourth mode to generate a fourth output voltage at the first node that is substantially equal to the other input voltage, wherein the at least one charger is further configured to selectively: transfer power from a first power supply circuit selectively coupled to the first node of the at least one charger to a first load based on the first mode or the second mode; and transfer power from a second power supply circuit to a second load selectively coupled to the first node of the at least one charger based on the third mode or the fourth mode.
