Claim 22:
23. An apparatus comprising: at least one power supply circuit; at least one load; at least one battery; a switching circuit coupled to the at least one power supply circuit and the at least one load; and at least one charger comprising: a first node coupled to the switching circuit; and a second node coupled to the at least one battery, the at least one charger configured to selectively: transfer power from the at least one power supply circuit to the at least one battery based on the switching circuit connecting the at least one power supply circuit to the first node; or transfer power from the at least one battery to the at least one load based on the switching circuit connecting the at least one load to the first node, wherein the at least one charger is configured to selectively operate as a voltage-divider-type charge pump, a voltage-multiplier-type charge pump, or a direct charger, wherein the at least one charger is configured to selectively: operate as the voltage-multiplier-type charge pump to transfer power from the at least one power supply circuit to the at least one battery; or operate as the voltage-divider-type charge pump to transfer power from the at least one battery to the at least one load.
