To provide a better charging and power supply device.SOLUTION: A charging and power supply device 10 comprises: a housing 12 formed in a substantially polyhedral shape; first ventilation paths 36A, 36C, and 36D formed in first faces 18A, 18C, 18D, and 18F of a plurality of faces 18A to 18F of the housing; and a second ventilation path 36E formed in a second face 18E different from the first face. A cross-sectional area of the first ventilation path and the cross-sectional area of the second ventilation path are different from each other. The first ventilation path is an intake passage, the second ventilation path is an exhaust passage, and the cross-sectional area of the first ventilation path is smaller than that of the second ventilation path. The charging and power supply device 10 further includes a heat generator disposed inside the housing and an air blower for cooling the heat generator.SELECTED DRAWING: Figure 5 【課題】より良好な充電給電装置を提供する。【解決手段】充電給電装置１０は、略多面体状に形成された筐体１２と、筐体の複数の面１８Ａ〜１８Ｆのうちのいずれかである第１面１８Ａ、１８Ｃ、１８Ｄ、１８Ｆに形成された第１通気路３６Ａ、３６Ｃ、３６Ｄと、第１面と異なる第２面１８Ｅに形成された第２通気路３６Ｅと、を備える。第１通気路の断面積と第２通気路の断面積とが互いに異なる。第１通気路は吸気路であり、第２通気路は排気路であり、第１通気路の断面積は第２通気路の断面積より小さい。筐体内に備えられた発熱体と、発熱体を冷却するための送風機とを更に備える。【選択図】図５
