  "textContent": "The present invention relates to the field of terminal technologies, and discloses a method and a system for supplying power to a USB device. The system includes a USB device and a host, where the USB device is connected to the host through a USB cable, and the host may supply power to the USB device through the USB cable. The power supplying method includes: when a power supplying state of the host changes, automatically switching a power supplying manner for the USB device; when an electric quantity of the USB device is low, performing comprehensive analysis on power supplying state information of the USB device and the host according to a rule set by a monitoring program, selecting a proper power supplying manner and implementing dynamic switching of the power supplying manner. According to the present invention, the power supplying manner may be dynamically switched in a case that a connection is not broken, which ensures electricity supply to the USB device in a case that endurance of the host itself is ensured.",
