Abstract
Embodiments of the present invention relate to a portable charging case that can serve as both a charging base and a protective carrying case for a rechargeable stylus. The portable charging case can enable a quick connect and release of the stylus using magnetic force for magnetic engagement of the stylus to the charging base. The charging base may include a logic board that dynamically changes the polarity of the charge coming in through the charging base charging contacts. Such a dynamic change of polarity can recharge the stylus irrespective of the polarity alignment between the stylus charging terminals and the charging base charging contacts.
