Abstract: An apparatus is disclosed for adaptively providing power. In example implementations, an apparatus includes a power adapter coupler, at least one transistor, a first charger, and a second charger. The first charger and the second charger are coupled between the power adapter coupler and the transistor. The apparatus also includes a first switch, a second switch, and a charging controller. The first switch is coupled in series with the first charger between the power adapter coupler and the transistor. The second switch is coupled in series with the second charger between the power adapter coupler and the transistor. The charging controller is coupled to the first switch and the second switch. The charging controller is configured to selectively close the first switch to connect the first charger to the at least one transistor or close the second switch to connect the second charger to the at least one transistor.

Abstract: A dual port charging architecture is generally disclosed. For example, the dual charging architecture may include a first board portion having a first battery port configured to be coupled to a first set of battery terminals of a battery, a second board portion having a second battery port configured to be coupled to a second set of battery terminals of the battery, a connection portion electrically coupled between the first board portion and the second board portion, a first power path coupling a power input port of the second board portion to the first battery port via the connection portion, and a second power path coupling the power input port to the second battery port.
