[0018] The present invention relates to a portable charger designed to provide a convenient and versatile charging solution for smartphones, tablets, and other mobile devices on the go. The present invention discloses an adjustable output port mechanism, a novel feature that significantly enhances the portable charger's adaptability and user-friendliness. The demand for reliable and efficient portable charging solutions has become crucial in the mobile technology industry. While powerful, traditional portable chargers often struggle to meet the diverse needs of users, particularly those using protective cases of varying thicknesses. This mismatch forces users to remove these cases to establish an electrical connection between the mobile device and the portable charger, which is not only cumbersome but can also damage the device. Furthermore, compatibility issues arise with the various types of charging connectors required by different mobile devices. Users often have to carry multiple cables or adapters to accommodate this diversity, which diminishes the convenience that portable chargers are supposed to provide. The present invention addresses these challenges by providing an adjustable output port mechanism that easily adjusts the height of the output port, enabling a seamless connection with the mobile device regardless of the protective case used. Furthermore, the present invention incorporates an integrated plug that provides alternative connection types, further expanding its compatibility with a wide range of devices. This dual approach—adjustability and multiple connection options—is designed to provide a comprehensive solution to the limitations of existing portable power banks, thereby improving the user charging experience in different scenarios. By addressing these specific user issues, this invention establishes a new standard in portable charger design, providing convenience and adaptability currently lacking in the market.

[0019] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 Shows an exploded view of the portable charger. Figure 2 Describes the situation where the portable charger has its output port retracted in the assembled state. Figure 3 The portable charger 100 is shown with its output port extended. As described in the previous paragraph, the portable charger 100 is more than just a container for a battery 120 (e.g., a high-capacity lithium-ion battery). The charger's distinguishing feature, the adjustable output port mechanism 140, demonstrates the portable charger's versatility. Figure 1 、 Figure 2 and Figure 3 From the exploded view and the perspective view shown in FIG, people can understand how the adjustable output port mechanism 140 is cleverly integrated into the compact form of the portable charger 100.

[0020] The portable charger 100 also includes a circuit board 130, which serves as the central hub for managing power flow within the portable charger 100. It houses the necessary electronic components to regulate charging for safety and efficiency. This circuit board 130 oversees the distribution of power from the battery 120 to the output port 160 and manages power received from an external power source via the USB Type-C charging port 132. In addition to allowing power from an external power source to charge the battery 120, the USB Type-C charging port 132 can also provide power to other mobile devices, enabling bidirectional charging and discharging capabilities.

[0021] Additionally, the portable charger 100 includes an integrated plug 170 that provides additional connectivity options. When not in use, the integrated plug 170 retracts into the body of the portable charger 100, maintaining the portable charger 100's streamlined profile and portability. The integrated plug 170 demonstrates the charger's versatility, providing an alternative charging solution for mobile devices that may require a different connector (e.g., a USB, micro-USB, or USB-C charging connector; in this embodiment, a USB charging connector).

[0022] Therefore, the portable charger 100 exhibits a multifunctional nature as it can adapt to the needs of various electronic devices. Whether the user needs to charge a smartphone or tablet computer multiple times, or needs to provide power to USB-powered devices such as digital cameras or wireless headphones, the portable charger 100 is designed to meet these needs in an efficient and user-friendly manner.

[0023] In this embodiment, the portable charger 100 further includes a remaining power display 180, which is installed in the opening 154 (eg, Figure 1 The remaining charge display 180 provides a visual indication of the remaining charge, offering the user a clear and convenient way to monitor the charger's charge status. Furthermore, in this embodiment, the housing formed by the front housing 150 and the rear housing 110 provides protection and support for the internal components of the portable charger 100. The housing formed by the front housing 150 and the rear housing 110 is designed to house the battery 120 and the adjustable output port mechanism 140, ensuring the durability and aesthetics of the portable charger 100.

[0024] In addition, in this embodiment, the front housing 150 also includes a retractable horizontal screen bracket 155. That is, when a user uses this portable charger 100 to charge a mobile device (such as a smartphone or tablet computer), the horizontal screen bracket 155 folds outward to support the mobile device horizontally while charging. This function is particularly useful for users who want to watch videos or make video calls without holding their mobile device while the portable charger 100 powers the mobile device. The horizontal screen bracket 155 is integrated into the front housing 150 of the portable charger 100 when not in use. That is, when not in use, the horizontal screen bracket 155 will be folded back into the opening 152 of the front housing 150 to maintain a streamlined and compact design.

[0025] In this embodiment, the core of the portable charger 100 is an ingenious adjustable output port mechanism 140. The following will further discuss the components that constitute the adjustable output port mechanism 140. Please also refer to Figure 4 and Figure 5 , Figure 4 Provides a detailed view of the adjustable output port mechanism, while Figure 5 An exploded view of the adjustable output port mechanism is presented. The adjustable output port mechanism 140 includes an auger screw 141, a component that converts rotational motion into vertical motion. The auger screw 141 interacts directly with the internal threads 144a of the platform 144. By interacting with a control wheel 142 exposed on the front housing 150 of the portable charger 100, the user can easily adjust the height of the output port 160. Furthermore, the platform 144 supports the output port 160, which can move vertically along guide rails 143. The guide rails 143 ensure that the movement of the platform 144 is limited to the vertical axis, eliminating potential lateral or angular variations. The output port 160 serves as the contact point for the portable charger 100 to transmit power to the mobile device. Its vertical adjustability is a direct result of the movement of the platform 144, enabling it to effectively connect to mobile devices with protective cases of varying thicknesses. This feature addresses a common concern among portable charger 100 users, providing an innovative and practical solution.

[0026] In addition, the adjustable output port mechanism 140 further includes a top plate 145 and a base 146. The base 146 is used to support the guide rails 143 and the platform 144. In this embodiment, the top plate 145 and the base 146 are fixed to the rear shell 110 of the housing, so that the adjustable output port mechanism 140 can be firmly fixed inside the portable charger 100.

[0027] The operation of the adjustable output port mechanism 140 in the portable charger 100 is quite simple and efficient, ensuring that the user can easily adjust it according to their charging needs. Figure 6 , Figure 6A flowchart is presented to illustrate the process of adjusting the position of the output port 160 using the adjustable output port mechanism 140. First, referring to step S110, the user estimates the required height adjustment of the output port 160 based on the thickness of the protective case of the mobile device. Then, referring to step S120, the user interacts with the control wheel 142, partially exposed on the exterior of the front housing 150 of the portable charger 100, by rotating the control wheel 142 in this embodiment. Next, referring to step S130, by rotating the control wheel 142, the user activates the rotation of the screw 141 of the adjustable output port mechanism 140. As shown in step S140, as the screw 141 rotates, it interacts with the internal threads 144a of the platform 144, causing the platform 144 and the output port 160 mounted thereon to rise or fall.

[0028] It is worth noting that once the outlet port 160 is adjusted to the desired height, it needs to be secured to prevent accidental contraction or extension during use. In this embodiment, this is achieved through a friction fit mechanism (i.e., a tight fit), a design choice that utilizes the friction between the helical screw 141 and the internal threads 144a of the platform 144. The resulting friction is sufficient to maintain the platform 144, and therefore the outlet port 160, in position under normal use conditions.

[0029] In addition, in this embodiment, the output port 160 is a USB type C charging connector, but it can also be a Lightning or other type of charging connector to meet the needs of major smartphones, tablet computers and other mobile devices on the market today.

[0030] Next, please refer to Figure 7 , Figure 7 Shown is a power supply line 162 that supplies power to the output port 160. Figure 7 As can be seen, the power supply lines 162 extend laterally from both sides of the platform 144, bypassing the auger screw 141 and the control wheel 142. This ensures that the power supply lines 162 do not interfere with the movement of the auger screw 141 and the platform 144, nor with the components within the portable charger 100. The power supply lines 162 are flexible enough to withstand the stresses of repeated movement. Furthermore, the power supply lines 162 are adequately insulated and secured to the platform 144 to prevent wear or damage over time.

[0031] In summary, the above embodiments demonstrate a uniquely designed portable charger equipped with an adjustable output port mechanism that provides a convenient and versatile charging solution for smartphones, tablet computers, and other mobile devices. The present invention solves common compatibility issues with traditional portable chargers, such as compatibility with various protective cases and the need for multiple connectors. By integrating an adjustable output port and an integrated plug that provides alternative connection options, the charger improves compatibility with various devices, thereby providing a comprehensive solution to the limitations of existing portable chargers. The addition of a retractable horizontal screen stand further enhances its functionality, allowing users to comfortably watch videos or make video calls while charging. This portable charger represents a major advancement in mobile technology, providing a high degree of convenience and adaptability for users' charging needs.
