Abstract: A charging combination includes a power output device which is configured to output electric energy constantly or adjustably and a power input device which is configured to receive electric energy from the power output device. The power output device includes a power supply module for storing electric energy or obtaining electric energy from an external power grid as an energy source, a first USB connector for being connected with the power supply module and at least configured to transfer electric energy, and a first control module having a first controller which is at least configured to control an output voltage of the first USB connector when supplying electric energy. The power input device comprises a second USB connector at least configured to be electrically coupled to the first USB connector for transferring electric energy, and a second control module comprising a second controller at least configured to communicate with the first controller and to control the second USB connector.
