Abstract
A portable device including a secondary battery, a plurality of driving components driven by charged power of the secondary battery, a charging unit configured to charge the secondary battery by an input of outside power supplied from outside of the portable device, a plurality of transformation units each configured to output the charged power of the secondary battery at a driving voltage of a corresponding one of the plurality of driving components, a detection unit configured to detect the input of the outside power to the charging unit, and a switching controller configured to switch a state of one of the plurality of transformation units from an operation state to a stopped state responsive to detecting the input of the outside power to the charging unit causing only the corresponding one of the plurality of driving components to stop operation during charging of the secondary battery.
