[0034] The power conversion circuit module 2 is installed inside the main housing 1 and is electrically connected to the power input interface 11 via a circuit board. The buck circuit 21 and boost circuit 22 in the power conversion circuit module 2 are composed of high-performance power chips and peripheral circuits, and can automatically adjust the output voltage according to a preset program. The output voltage range is 3V-24V, which can meet the power supply requirements of most electronic devices.
[0035] The interface switching control module 3 is also installed inside the main housing 1 and is electrically connected to the power conversion circuit module 2 and the power output interface group 12 via ribbon cables. The logic control unit 32 in the interface switching control module 3 uses a microcontroller, which can identify the interface type and signal characteristics of the connected device, and control the corresponding relay 31 to operate according to a preset program, so as to realize automatic interface switching and adaptation.
[0036] The safety protection module 4 is installed inside the main casing 1 and is electrically connected to the power conversion circuit module 2, the interface switching control module 3, and the power output interface group 12 via circuitry.

The interface status indicator 52 displays different colors according to the interface's operating status; for example, the indicator for an interface transmitting data displays blue, and the indicator for an interface that is connected but not transmitting data displays yellow. The alarm indicator 53 illuminates red when the safety protection module 4 detects an abnormality, alerting the user. Through the signal indicator module 5, the user can intuitively understand the device's operating status.
