<p>A method, a device and a system for enhancing output power dissipation of a Universal Serial Bus (USB) interface are disclosed. The method includes: an emitting module obtains electrical energy, and converts the obtained electrical energy into electromagnetic energy (101); and a receiving module converts the electromagnetic energy into electrical energy, and transmits it to a USB terminal (102). By way of wireless power supply, the USB terminal is provided with wireless power, the output power of the USB interface is supplemented, the ability of the output power dissipation of the USB interface is enhanced, and the problem that the output power of the USB interface is insufficient is solved. The user still can normally use the high-power USB terminal without a USB two-port cable and an external wired power adapter. The energy transfer from one emitting module to multiple receiving modules in the area covered by an electromagnetic field also can be achieved, so as to realize a one-to-many power supply mode. Meanwhile, by integrating the emitting module into a notebook computer and integrating the receiving module into the USB terminal, the portability is improved, and the use of the user is facilitated.</p> |
