Abstract
A charging device for commonly charging multiple digital electronic devices has a housing, a charge control unit and multiple outlet strips. The charge control unit is mounted inside the housing and has multiple relays. The outlet strips are electrically connected to the charge control unit with each outlet strip electrically connected to one of the relays. A charging method corresponding to the charging device is performed by the charge control unit without the need of users' configuration during a charge cycle. The charge method automatically determines if the outlet strips can simultaneously supply power to charge during each charge schedule of the charge cycle. At least one outlet strip supplies power to charge during each charge schedule, and each outlet strip supplies power to charge once, thereby achieving optimization for the charging process with automatic determination and enhancing charging efficiency and users' operational convenience.
