Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a centered element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a centered element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method. The terms "upper end", "lower end", "left side", "right side", "front end", "rear end" and similar expressions used herein are positional relationships with reference to the accompanying drawings.

[0018] In order to make the technical solutions and advantages of the present invention more clear, the implementation modes of the present invention will be described in further detail below with reference to the accompanying drawings.

[0019] See also Figure 1-3 As shown, the utility model provides a single-line dual-interface luggage fast charging cable, including a USB-A plug 1, an extension cable 2, a PCB board 4, and a type-c port 5 and a USB-A port 6 installed on the PCB board 4. The USB-A plug 1 is electrically connected to the PCB board 4 through the extension cable 2. The PCB board 4 includes Vbus, GND, D+, and D- terminals. The charging device triggers the fast charging mode of the USB-A port 6 through the voltage recognition of the D+ and D- terminals. The extension cable 2 is a fast charging cable. In this embodiment, the wire of the extension cable 2 uses multiple copper cores inside and a nylon braided outer sheath outside. Figure 2 As shown, the PCB board 4 is fixedly installed in the storage compartment 32 of the protective shell 3, and the protective shell 3 is also provided with a sealing cover plate 31 to seal the PCB board 4. Figure 3 As shown, the Vbus and GND line widths on the PCB board 4 are greater than 2MM to allow large currents to pass through.

[0020] In order to have a more thorough and comprehensive understanding of the disclosed content of the utility model, the principle thereof is further explained below in combination with the usage method.

[0021] When in use, insert the USB-A plug 1 into the charging port of the mobile power supply in the bag, and extend the type-c port 5 and USB-A port 6 outside the bag through the extension cable 2. When the user needs to charge, plug one end of the data cable into the device to be charged, and the other end into the type-c port 5 or USB-A port 6. It should be noted that the type-c port 5 only supports the slow charging function, which can be used to slow charge the IOS system series mobile phones and Android system mobile phones, and also supports the charging of various digital electronic products. The USB-A port 6 supports the fast charging function and slow charging function of mobile phones of the Android system and IOS system, and also supports the charging of various digital electronic products. When the fast charging function is enabled, the charging device needs to trigger the fast charging mode of the USB-A port 6 through the voltage recognition of the D+ and D- terminals. After use, the sealing cover plate 31 needs to seal the type-c port 5, USB-A port 6, and PCB board 4 to prevent dust and water vapor from entering.
