There are disclosed herein various implementations of a power management system for powering a portable device while charging a multi-series-cell battery of the portable device when the portable device is connected to an adapter. One exemplary implementation comprises a voltage regulator for powering the portable device and a multi-mode charger receiving input power from the adapter. The multi-mode charger is operated in a switching mode for charging the multi-series-cell battery concurrently with the voltage regulator powering the portable device. In another implementation, the power management system is adapted for use with a portable device having a single-cell battery.
