Beschreibung
Zusammenfassung:	A mobile power supply device comprises a shell, a battery assembly, an electric energy conversion assembly and a shielding mechanism. Universal wheels are installed at the bottom of the shell, a containing cavity and a storage cavity are formed in the shell, the containing cavity is designed in a sealed mode, and a plurality of heat dissipation holes communicated with the outside are formed in the cavity wall of the storage cavity; the battery assembly is mounted in the accommodating cavity; the electric energy conversion assembly is installed in the storage cavity and electrically connected with the battery assembly so that charging and discharging of the battery assembly can be achieved. The shielding mechanism comprises a baffle and a driving assembly, and the driving assembly is installed in the storage cavity and is in driving connection with the baffle, so that the baffle has a first position which abuts against the inner wall of the storage cavity and covers the heat dissipation holes and a second posi
