Abstract
An external storage device includes a memory, a controller, a first interface, a second interface, a first switching module, and a second switching module. The controller is coupled to the memory. The first interface is used to connect to a first electronic device. The second interface used to connect to a second electronic device. The first switching module is coupled to the controller, the first interface, and the second interface. The second switching module is coupled to the controller, the first interface, the second interface, and the first switching module. When the first interface is electrically connected to a first electronic device and the second interface is electrically connected to the second electronic device, the first electronic device charges the controller and the second electronic device through the first switching module, and the first electronic device accesses the memory through the second switching module and the controller.
