The invention relates to the technical field of charging, fast charging protocol chip application and the like, and provides a power rail management method of a multi-port USB charger and related equipment thereof. When a plurality of charging devices are connected to different ports of the multi-port USB charger for charging, identification information of the connected charging devices is automatically identified, and the charging efficiency is improved. According to the identification information of the automatically identified charging device, an independent power rail is arranged for each USB port of the multi-port USB charger, and an initial output voltage is configured for each independent power rail so as to charge the corresponding charging device, and the state change of the accessed charging device is monitored in real time. The output voltage of each independent power rail is dynamically adjusted according to the monitored state change and voltage and current output of the charging equipment throug
