1. A parallel multi-source power supply system with a unified output, comprising:
a first power supply including a first USB-C connector and a second USB-C connector;
a second power supply including a third USB-C connector electrically connected to said first power supply in parallel through said second USB-C connector;
wherein said first power supply is configured to operate in a constant current and constant voltage (CCCV) mode to output a first power, while said second power supply is configured to operate in a constant voltage (CV) mode to output a second power;
wherein said second power of said second power supply is transferred to said first power supply and unified with said first power to power an external electronic system with a fourth USB-C through said unified output; and
wherein an amount of said second power transferred to said first power supply is determined by a charging agreement through communicating between said first power supply and said external electronic system.
