Abstract
A power charging system for charging portable electric devices. The power charging system includes a plurality of transformers for transforming a plurality of different input voltages into a standard DC (direct current) voltage. The charging system also includes a power cord for inputting and outputting the standard DC voltage. The charging system also includes a plurality of converters for converting the standard DC voltage into the working voltage of the portable electric devices. Users connect the corresponding converters to the power cord and then connect the power cord to any one of the transformers to use the standard DC voltage to charge the portable electric devices.
