Abstract: The embodiments discussed herein relate to systems, methods, and apparatus for providing a charger capable of adaptively handling a range of power inputs. The charger can selectively activate different control switches within the charger in order to more efficiently use current supplied to the charger. When a low power input is provided to the charger, the charger can reduce the number of active control switches being used to provide a voltage output from the charger. In this way, the capacitance required to toggle the control switches can be reduced. When a high power input is provided to the charger, the number of active control switches can be increased in order to increase a total amount of charge that can be provided from the charger, thereby reducing charge times for batteries.
