Abstract
Portable electronic equipment which prevents an unwanted decrease in capacity of an internal battery of an external device, such as a smartphone, by cutting off feeding as necessary when connected to the external device, such as the smartphone, through a USB. The portable electronic equipment has a USB connector for connection with the external device, a feeding switch for turning on or off feeding to the secondary battery through a VBUS line, and a CPU. The CPU subjects the feeding switch to ON-control at all times or OFF-control at all times, or displays a selection menu for selecting feeding or unfeeding when the external device is connected to the USB connector. When a user selects feeding, the feeding switch undergoes ON-control. When the user selects unfeeding, the feeding switch undergoes OFF-control.
