[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0026] like Figure 2 and Figure 4As shown, a portable power bank with a card holder function includes a main body, which includes a housing 1. The housing 1 houses a battery and a PCB board. A storage slot 11 is provided on one side of the housing 1. One end of the storage slot 11 is damped and hinged to a card holder body 2. Two card storage cavities are sewn onto the card holder body 2. Each card storage cavity forms a card insertion port 21 at its end, allowing cards such as ID cards and bank cards to be inserted into the card storage cavity through the insertion port 21. A triangular elastic protrusion made of silicone material is provided in each card storage cavity, with the tip of the elastic protrusion facing the card insertion port 21. This allows the elastic protrusion to press firmly against the card inserted into the card storage cavity without affecting the insertion. The card holder body 2 is rotatable and has two states, one being... Figure 2 The storage state shown is completely located in the storage slot 11; another state is as follows: Figure 1 and Figure 4 The state described above when unfolded from the storage slot 11, in this state, as Figure 1 As shown, rotating the card holder body 2 can create a supporting state for the power bank body.

[0027] like Figure 2 As shown, the card holder body 2 is provided with a buckle structure 22 at the other end away from its hinge end. The buckle structure 22 facilitates the unfolding of the card holder body 2 from the storage slot 11.

[0028] like Figure 2 and Figure 3 As shown, a power switch 6 and a bidirectional charging interface 7 are provided on the side wall of the housing 1. Both the power switch 6 and the bidirectional charging interface 7 are electrically connected to the PCB board. The power switch 6 is used to turn the power bank on and off. The bidirectional charging interface 7 serves as both a charging input and output interface, which simplifies the design, reduces the number of interfaces on the power bank, makes the product appearance more concise and aesthetically pleasing, and also reduces production costs and product complexity. A power indicator light 3 is provided on the PCB board, and a light hole is provided on the side wall of the housing 1 at the corresponding position of the power indicator light 3. The power indicator light 3 indicates the approximate remaining power of the power bank.

[0029] like Figure 1 and Figure 3As shown, a faceplate 4 and a wireless charging assembly are provided on the other side of the housing 1. The wireless charging assembly includes a wireless charging coil disposed inside the faceplate 4 and a magnet 5 disposed on the surface of the faceplate 4. The wireless charging coil is electrically connected to a PCB board disposed in the housing 1 and is used to wirelessly charge electronic devices. The magnet 5 includes a ring magnet 51 and a bar magnet 52. The ring magnet 51 is positioned directly opposite the wireless charging coil, and the bar magnet 52 is positioned outside the ring magnet 51, with a distance between them. The faceplate 4 has a ring-shaped groove adapted to the ring magnet 51 and a bar-shaped groove adapted to the bar magnet 52. The ring magnet 51 and the bar magnet 52 are respectively disposed in the ring-shaped groove and the bar-shaped groove, and the outer end faces of the ring magnet 51 and the bar magnet 52 are located on the same plane. The ring magnet 51 and the bar magnet 52 cooperate with each other to provide adsorption force from different shapes and positions, which can better adsorb electronic devices such as smartphones, making the adsorbed electronic devices less prone to shaking and displacement. The cover 4 has a charging contact surface 41 inside the annular magnet 51. The charging contact surface 41 is on the same plane as the outer end face of the annular magnet 51, or the charging contact surface 41 is slightly lower than the outer end face of the annular magnet 51, so as to ensure the attraction function of the magnet 5 and make the wireless charging coil closer to the electronic device being charged.

[0030] In summary, this utility model features a card holder body 2 that can be used as a stand. The card holder body 2 can rotate freely within a certain range to the desired angle. The card holder body 2 simultaneously serves to store cards and support the power bank body. When carrying this utility model, there is no need to carry a separate card holder, making it very convenient to use. Furthermore, this utility model includes a wireless charging component with magnets 5, which can wirelessly charge electronic devices and simultaneously attract and hold the charged electronic devices, allowing users to easily view them, such as watching videos on a smartphone. Magnets 5 include a ring magnet 51 and a bar magnet 52. The ring magnet 51 is positioned directly opposite the wireless charging coil, while the bar magnet 52 is positioned outside the ring magnet 51, with a distance between them. The ring magnet 51 and the bar magnet 52 work together to provide attraction from different shapes and positions, effectively attracting smartphones and other electronic devices and preventing them from shaking or shifting.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
