[0031] In use, insert the battery into the battery retaining groove 400. The battery interface contacts the battery interface 500, allowing the multi-functional power converter to obtain electrical energy from the battery. The power conversion component 200 inside the converter housing 100 can convert the 18V DC power obtained from the battery through the power input interface 250 and output it to the electrical device through the power output component.

[0032] In this invention, the battery interface 500 includes a positive battery interface 510 and a negative battery interface 520; the power input interface 250 is electrically connected to the positive battery interface 510. A microcontroller control component 300 is also fixedly connected inside the converter housing 100. The microcontroller control component 300 is equipped with a 5V control interface 310, a 12V control interface 320, an 18V control interface 330, and a microcontroller power interface 340. This microcontroller control component 300 can control the power conversion component 200 to output 5V, 12V, or 18V DC power through the 5V control interface 310, 12V control interface 320, and 18V control interface 330.

[0033] A 5V voltage regulator module 240 is provided in the power conversion component 200. This 5V voltage regulator module 240 has a fourth output interface 242 and a fourth input interface 241. The power input interface 250 and the fourth input interface 241 are electrically connected, and the fourth output interface 242 is electrically connected to the microcontroller power interface 340. The fourth output interface 242 is used to provide DC power to the microcontroller control component 300. The 18V DC power obtained from the battery is input to the 5V voltage regulator module 240 through the fourth input interface 241. After processing by the 5V voltage regulator module 240, the 5V DC power is input to the microcontroller control component 300 through the fourth output interface 242, enabling the microcontroller control component 300 to operate stably.

[0034] The power conversion assembly 200 also includes a 5V output module 210, which comprises a first input interface 211, a first control interface 213, and a first output interface 212. The first input interface 211 is electrically connected to the power input interface 250. The first control interface 213 is electrically connected to the 5V control interface 310. Furthermore, the power output assembly includes a first peripheral interface 610, with the first output interface 212 electrically connected to it. The first peripheral interface 610 provides 5V DC power to the device. The purpose of this module is to step down the 18V DC power from the battery to 5V DC power, enabling the multi-functional power converter to charge electronic products such as mobile phones and wireless headphones, most of which require a rated voltage of 5V for charging. The first peripheral interface 610 in the power output assembly can use a USB (Universal Serial Bus) Type-A interface and / or a Type-C interface to accommodate charging cables with different interfaces.

[0035] In some embodiments, the power conversion component 200 includes a 12V output module 220, which includes a second input interface 221, a second control interface 223, and a second output interface 222.

The power output component includes a second peripheral interface 620, which is electrically connected to the second output interface 222. The second peripheral interface 620 can provide 12V DC power to the device. The second peripheral interface 620 can use a female connector of model XT60, enabling the multi-function power converter to convert 18V DC power from the battery to 12V DC power for the device. Most devices using 12V voltage can be connected to power cables via the female connector of XT60.

The third output interface 232 is electrically connected to the second peripheral interface 620, which provides 18V DC power to external devices. This module design enables the power conversion component 200 to not only step down 18V to 12V and 5V, but also maintain 18V, supplying power to devices with a rated voltage of 18V, further improving the applicability of the multi-functional power converter. Considering devices with a rated voltage of 18V, the 18V output module 230 also uses the second peripheral interface 620 for output.

The indicator light 700 is electrically connected to the microcontroller control assembly 300, and the switch assembly 800 is also electrically connected to the microcontroller control assembly 300. The indicator light is used to indicate the working status of the multi-functional power converter. When working, the indicator light 700 is constantly lit. When the multi-functional power converter is not working due to poor contact or battery depletion, the indicator light 700 is turned off. When the user presses and holds the switch assembly 800, the multi-functional power converter is turned on or off. When the user presses and holds the switch assembly 800 briefly, the microcontroller control assembly 300 controls the output voltage of the power conversion assembly 200 to 5V, 12V, or 18V. It can also control the power conversion assembly 200 to output voltages of 5V and 12V, or 5V and 18V.
