STRUCTURE AND METHOD FOR PROVIDING POWER TO EXTERNAL MOBILE DEVICES

摘要

A structure for providing power to external mobile devices has a first power supply module and a second power supply module. The first power supply module has a first voltage source outputting an activation current to a main circuit of an external mobile device when activated. The second power supply module has a first boost circuit and an activation circuit. A second voltage source from a computer supplies power to the first boost circuit through the first boost circuit to output a first operating current to the main circuit through the activation circuit to replace the activation current supplied from the first power supply module. The structure further has a blocking circuit blocking the first voltage source to keep supplying power for the purpose of energy conservation and carbon reduction when the external mobile device is powered off.
