[0031] The utility model relates to a portable charger designed to provide a convenient and versatile charging solution for smartphones, tablet computers and other mobile devices on the go. The utility model discloses an adjustable output port mechanism, which is a new feature that significantly enhances the portability and user-friendliness of the portable charger. In the mobile technology field, the demand for reliable and efficient portable charging solutions has become quite important. Although conventional portable chargers are powerful, they often perform poorly in meeting the diverse needs of users, especially for users who use protective cases of different thicknesses. This mismatch can cause users to have to remove these protective cases to establish an electrical connection between the mobile device and the portable charger, which is not only troublesome but can also cause damage to the equipment. In addition, the compatibility problem also involves various types of charging connectors required by different mobile devices. Users often need to carry multiple wires or adapters to meet this diversity, which in turn undermines the convenience that portable chargers should provide. The utility model addresses these challenges by having an adjustable output port mechanism that can easily adjust the height of the output port to achieve integrated connection with the mobile device, regardless of the protective case used. In addition, the utility model also integrates an integrated plug that provides an alternative connection type, further expanding its compatibility with various equipment. This dual approach - adjustability and multiple connection options - aims to provide a comprehensive solution to the limitations of existing portable power banks, thereby improving the charging experience of users in different situations. By addressing these specific user problems, the utility model establishes a new design standard for portable chargers, providing the convenience and applicability that the market currently lacks.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 shows an exploded view of the portable charger, Figure 2 describes the output port of the portable charger retracted in the assembled state, Figure 3 shows the output port of the portable charger extended. As described in the above paragraph, this portable charger 100 is not just a container for a battery 120 (e.g. a high-capacity lithium-ion battery), the outstanding feature of this charger, namely the adjustable output port mechanism 140, embodies the portability of the portable charger 100. Through the exploded view and perspective view shown in Figure 1 、 Figure 2 and Figure 3 , one can understand how this adjustable output port mechanism 140 is ingeniously integrated into the compact form of the portable charger 100.

[0033] 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.

[0034] 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).

[0035] 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.

[0036] 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.

[0037] In addition, in the present embodiment, the front housing 150 further comprises a retractable landscape stand 155. That is, when a user is charging a mobile device (e.g. a smartphone or a tablet computer) using the portable charger 100, the landscape stand 155 is folded outwards to horizontally support the mobile device while it is being charged. This feature is particularly useful for users who want to watch videos or make video calls without having to hold the mobile device while it is being powered by the portable charger 100. The landscape stand 155 is integrated into the front housing 150 of the portable charger 100 when not in use, that is, the landscape stand 155 is folded back into the opening 152 of the front housing 150 to maintain a streamlined and compact design.

[0038] In the present embodiment, the core of the portable charger 100 is a clever adjustable output port mechanism 140. The components that make up the adjustable output port mechanism 140 are discussed in depth below, please refer to Figure 4 and Figure 5 , Figure 4 a detailed view of the adjustable output port mechanism is provided, while Figure 5 presents an exploded view of the adjustable output port mechanism. The adjustable output port mechanism 140 comprises a screw spindle 141, which is a component that converts rotational motion into vertical motion. The screw spindle 141 directly interacts with the internal threading 144a of the platform 144. By interacting with the control wheel 142, which is exposed on the outside of the front housing 150 of the portable charger 100, the user can easily adjust the height of the output port 160. In addition, the platform 144 carries the output port 160, which can move vertically along the guide rail 143, the function of which is to ensure that the movement of the platform 144 is limited to the vertical axis, eliminating possible lateral or angular changes. The output port 160, 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 mobile devices with different thicknesses of protective cases. This feature solves the common problem faced by users of the portable charger 100, providing an innovative and practical solution.

[0039] In addition, the adjustable output port mechanism 140 further comprises a top plate 145 and a base 146, which is used to support the guide rail 143 and the platform 144. In the present embodiment, the top plate 145 and the base 146 are fixed to the rear housing 110 of the outer shell, so that the adjustable output port mechanism 140 can be stably fixed inside the portable charger 100.

[0040] The operation of the adjustable output port mechanism 140 inside the portable charger 100 is quite simple and efficient, ensuring that users can easily adjust according to their charging needs. Below, please refer to Figure 6 , Figure 6A flow chart is presented to illustrate the process of adjusting the position of the output port 160 using the adjustable output port mechanism 140. First, refer to step S110, the user estimates the height of the output port 160 that needs to be adjusted according to the thickness of the protective case of the mobile device. Then, refer to step S120, the user interacts with the control wheel 142 that is partially exposed outside the front housing 150 of the portable charger 100, in this embodiment, by rotating the control wheel 142. Next, refer to step S130, by rotating the control wheel 142, the user initiates the rotation of the screw rod 141 of the adjustable output port mechanism 140. After that, as shown in step S140, as the screw rod 141 rotates, it interacts with the internal thread 144a of the platform 144, causing the platform 144 and the output port 160 mounted on the platform 144 to rise or descend.

[0041] It is worth noting that once the output port 160 is adjusted to the desired height, it needs to be fixed to prevent accidental retraction or extension during use. In this embodiment, this is achieved by a friction fit mechanism, i.e., a tight fit, which is a design choice that takes advantage of the friction between the screw rod 141 and the internal thread 144a of the platform 144. The resulting friction is sufficient to maintain the position of the platform 144, and thus the output port 160, under normal usage conditions.

[0042] 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 the main smartphones, tablet computers and other mobile devices on the market today.

[0043] Next, refer to Figure 7 , Figure 7 The power supply line 162 is shown to supply power to the output port 160. As can be seen from Figure 7 , the power supply line 162 extends laterally from both sides of the platform 144, bypassing the screw rod 141 and the control wheel 142, to ensure that the power supply line 162 does not interfere with the movement of the screw rod 141 and the platform 144, nor does it interfere with the components inside the portable charger 100. The power supply line 162 has a certain flexibility to withstand the stress caused by repeated movements. In addition, the power supply line 162 is sufficiently insulated and fixed to the platform 144 to prevent wear or damage over time.

[0044] In summary, the above embodiments demonstrate a uniquely designed portable charger that is equipped with an adjustable output port mechanism that provides a convenient and versatile charging solution for smartphones, tablets, and other mobile devices. The present invention addresses the common compatibility issues of 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 offers alternative connection options, this charger improves compatibility with a variety of devices, thus providing a comprehensive solution to the limitations of existing portable chargers. The addition of a stowable landscape stand further enhances its functionality, allowing users to comfortably watch videos or engage in video calls while charging. This portable charger represents a significant advancement in the mobile technology field, offering users a high degree of convenience and adaptability in their charging needs.
