摘要：This power supply device is provided with: an AC circuit part (1) having an AC power supply (10) as the input source, and outputting prescribed DC power; a secondary cell (2) charged by the power outputted by the AC circuit part (1); an output connector (3) for connecting electronic equipment (30) to be supplied with power; and a power feed controller (4) which has the output of the AC circuit part (1) as the power supply, for controlling the charging and discharging of the secondary cell (2), and for outputting the output of the AC circuit part (1) or the secondary cell (2) to the output connector (3) and supplying power to the electronic equipment (30) connected to the output connector (3). In a first connection state in which the AC power supply (10) is connected to the AC circuit part (1) and the electronic equipment (30) is connected to the output connector (3), the power feed controller (4) uses the output of the AC circuit part (1) to feed power to the electronic equipment (30) in a preferential manner with respect to charging of the secondary cell (2), and initiates charging of the secondary cell (2) upon detecting that the power feed to the electronic equipment (30) has fallen to or below a threshold value.
