[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] As per the instruction manual Figure 1 , 2 As shown in Figures 3 and 4, a single-cell portable power bank 1 with wireless charging capability is included. To ensure diverse power supply and charging capabilities, the top surface of the single-cell portable power bank 1 has a wired charging port 11 (USB-C interface) and a universal charging port for data cables. The front has a magnetic charging plate for wireless charging and a display screen for displaying the power level. A solar charging plate 2 is provided on the opposite side of the magnetic charging plate for wireless charging of the single-cell portable power bank 1. To prevent the mobile phone from overheating due to exposure to sunlight when the solar charging plate 2 is supplying power and wireless charging simultaneously, the solar charging plate 2 and the single-cell portable power bank 1 are separate structures. The solar charging plate 2 is connected to the current collection system of the single-cell portable power bank 1 through a wire. In order to ensure that the power supply speed can keep up with the power consumption speed, there are multiple solar charging plates 2, and the photovoltaic surfaces of every two solar charging plates 2 are folded and connected by a hinge. This not only saves lateral space, but also protects the photovoltaic surfaces from damage due to direct external pressure.

[0022] When needed, unfold the solar charging panel 2 and connect each group of solar charging panels 2 using the double-headed sliding clamp 21. To prevent loosening during connection, anti-slip pads are attached to the inner walls of both sides of the double-headed sliding clamp 21. The upper and lower ends of the double-headed sliding clamp 21 and the solar charging panel 2 are provided with protruding strips 22 that engage with the double-headed sliding clamp 21. To facilitate connecting multiple double-headed sliding clamps 21 in the same direction, the left and right ends of the double-headed sliding clamp 21 are provided with pins 211 and pin holes 212. The pins 211 and pin holes 212 are located at the upper and lower ends of one side of the double-headed sliding clamp 21, respectively, meaning the pins 211 and pin holes 212 are evenly distributed at the upper and lower ends of the double-headed sliding clamp 21. To ensure the matching of the pins 211 and pin holes 212, the double-headed sliding clamp 211... 1. The pins 211 and pin holes 212 at the left and right ends face opposite directions. Pins 211 and pin holes 212 must fit tightly; otherwise, the connection of the double-headed sliding clamp 21 may loosen. To prevent hand injuries during assembly, metal parts are not recommended for the double-headed sliding clamp 21. Therefore, the double-headed sliding clamp 21 of this device is made of high-temperature resistant and impact-resistant PC endurance board. The shell made of PC endurance board is not easily cracked under normal use conditions. However, its compressive strength is affected by factors such as material thickness, processing technology, and usage environment. In common cases, the impact strength of PC endurance board is 250 times that of ordinary glass and 30 times that of tempered glass, and it can even withstand extreme impacts such as hail and typhoons. Its tensile strength remains at 350 kgf / cm² at 120°C. 2 It has excellent bending strength and is not easy to break even when bent at 90°, which means that the shell is not easily crushed under normal mechanical pressure.

[0023] To facilitate the storage of these solar charging panels 2 and double-headed sliding clips 21, a leather sleeve 3 for storing the solar charging panels 2 is attached to the outer wall of the single-cell portable power bank 1. The top surface of the leather sleeve 3 is provided with a movable opening 31 that is closed by a zipper. The leather sleeve 3 is connected to the narrow side wall of the single-cell portable power bank 1 by three-way universal adhesive. In order not to affect the normal use of the wired charging port 11, a charging slot 12 corresponding to the wired charging port 11 is provided on the top surface of the leather sleeve 3.

[0024] In practical implementation, the charging method can be selected according to needs. If wireless charging is selected, and the single-cell portable power bank 1 is low on power during charging, simply unzip the movable opening 31, then take out each solar charging panel 2. After opening the solar charging panel 2, use the double-headed sliding clip 21 to fix the upper and lower ends of each solar charging panel 2, and then assemble them through the pins 211 and pin holes 212 on the left and right ends of the double-headed sliding clip 21. Then place it in a sunny place to charge. The number of solar charging panels 2 can be automatically controlled and adjusted according to the maximum power consumption of the single-cell portable power bank 1. The connecting wires between the solar charging panels 2 and the single-cell portable power bank 1 can also be designed to be detachable or integrated as needed. The leather case 3 usually also has a storage bag sewn inside to store the double-headed sliding clip 21.
