Abstract
The present invention relates to a includes a USB port connector and a charging connector. The USB port connector is used to plug into the jack of the USB port while the charging connector is used to plug into the jack of the electronic products to be charged. The current flowing into the USB port connector will then pass through an automatic voltage regulator. Disposed within a housing of the automatic voltage regulator is a DC voltage transformer which transforms the DC voltage (5V) coming from the USB port to the required voltage supplied to a power/signal connecting jack. Provided within the DC voltage transformer is furthermore a feedback control voltage output circuit which compares the feedback voltage signal of the power/signal connecting jack and enable the DC voltage transformer to output a preset voltage. The charging connector is fitted with a power cord which includes a power/signal connecting connector to fit the power/signal connecting jack. Moreover, a required voltage parameter is preset within the charging connector.
