Abstract
In the charging process of a power device of a portable device, a control unit or firmware of the power device dynamically acquires the status of the charging current and the charging voltage, and by incrementing the charging current, the power device correctly obtains maximum charging current affordable by a charger without overly drawing the current from the charger that causes overly low charging voltage. Such current-adaptive charging process optimizes the charging process.
