  "textContent": "A power supply device includes: a power storage unit including a first power storage device and a second power storage device; and a first switch used, when a first condition is satisfied, to switch a power supply source to a first electric device between the first power storage device and the second power storage device in order to drive the first electric device for at least a first time. The first power storage device is capable of supplying power to a load and the first electric device. The second power storage device is capable of supplying power to the load and the first electric device. In a first use mode in which the power supply source to the first electric device is set to the first power storage device, until the first condition is satisfied, power supply from the first power storage device to the load and the first electric device and power supply from the second power storage device to the first electric device are restricted. In the first use mode, when the first condition is satisfied, the power supply from the first power storage device to the load is restricted, the power supply from the second power storage device to the first electric device is restricted, and the power supply from the first power storage device to the first electric device is performed.",
