The power supply device as claimed in claim 4, a data storage unit is arranged in the casing, and the data storage unit is electrically connected with the main control unit; wherein: the main control unit is set with a first device type, a second device type device type, a third device type, a first transmission protocol, a second transmission protocol, and a third transmission protocol; step (b2) in the above-mentioned simultaneous data transmission procedure includes: when the main control unit is According to step (a2), it is determined that the external electronic device that sends the command is the first device type, the master control unit will switch from the default master mode to the slave mode, and add a first data storage in the data storage unit When the instruction in step (b2) requires data backup, the main control unit establishes a data transmission path between the external electronic device and the first data storage area, and uses The first transmission protocol obtains the data of the external electronic device, and stores it in the first data storage area together with its device number; or when the instruction requires data reading, the first transmission protocol and its device number are used from the first transmission protocol and the device number. The first data storage area reads its data; when the main control unit determines according to step (a2) that the external electronic device that issues the command is the second device type, the main control unit maintains the default main mode, and in the When a second data storage area is added in the data storage unit, and the instruction in step (b2) requires data backup, the main control unit establishes a data transmission path between the external electronic device and the second data storage area, and uses The second transmission protocol obtains the data of the external electronic device and stores it in the second data storage area; or when the instruction requires data reading, the second transmission protocol and its device number are used from the second data The storage area reads its data; and when the main control unit determines according to step (a2) that the external electronic device issuing the command is of the third device type, the main control unit will switch from the default master mode to the slave mode, When the instruction in step (b2) requires data access, the data storage unit is opened, and the main control unit establishes the external electronic device and the data storage unit, and performs data access using the third transmission protocol. The power supply device according to claim 5, wherein the step (b2) in the above-mentioned simultaneous data transmission procedure further comprises: when the main control unit requests data transmission according to the instruction of the step (b2), the main control unit The interface controllers of the external electronic devices that agree to perform data transmission are electrically connected to establish a data transmission path. The power supply device according to any one of claims 1 to 3, wherein the AC connector is an AC plug, which is arranged on the housing or is arranged on the housing through a power cord. The power supply device according to any one of claims 1 to 3, wherein the data storage unit is SD, eMMC, UFS, U-Disk, HDD or SSD. The power supply device of any one of claims 1 to 3, wherein the multi-interface port includes USB interface ports of different USB standards. The power supply device of claim 5, wherein: the first device type is an electronic device type using an iOS operating system; the second device type is an electronic device type using an Android operating system; and the third device type It is the type of electronic device that uses the Windows operating system.
