PROBLEM TO BE SOLVED: To more effectively use power in consideration of residual capacity of a plurality of batteries and power consumption of a plurality of loads. SOLUTION: The electronic equipment is provided with: batteries 10A and 10B as power sources; loads 20A to 20C operating with power to be supplied from one of the batteries 10A and 10B; switches SW1A to SW1C and SW2A to SW2C for switching paths for supplying power from the batteries 10A and 10B to the loads 20A to 20C; voltage detection circuits 11A and 11B for detecting the residual capacity of the batteries 10A and 10B; and a control circuit 30 for measuring the power consumption of each of the loads 20A to 20C, selecting the combination of the batteries 10A and 10B which supply power to the loads 20A to 20C based on the measurement result and the detection result, switching the switches SW1A to SW1C and SW2A to SW2C according to the selection result, and causing the batteries 10A and 10B to supply power to the loads 20A to 20C.
