[0002] At present, portable electronic devices generally have the problem of short battery life, such as smartphones basically need to be charged once a day. In order to keep the device powered at all times, the widely used method is to carry a mobile power supply. Traditional mobile power supplies need to carry a data cable separately, which is easy to entangle and inconvenient to carry. Since the retractable data cable device can store the wires in the storage mechanism to avoid scattering and entanglement, it is welcomed by many users. For this reason, some people set a retractable data cable device in the mobile power supply to replace the independent data cable, which is convenient for carrying and using. However, there are still some problems with this type of mobile power supply, such as the friction between the data cable and its shell when it is pulled out from the storage mechanism, the pulling out and retracting are not smooth enough, and the design is not user-friendly enough. At the same time, the existing mobile power supply is generally designed in a square or round structure, but since lithium batteries (such as 18650 batteries) are usually cylindrical, the use of a square or round structure in the case of two batteries superimposed with a retractable data cable will cause the overall size of the product to be larger, and the shape is too ordinary.

[0007] Furthermore, the circuit board is in a triangular shape and covers the storage mechanism.

[0008] Furthermore, a partition is provided near both sides of the shell, and the two partitions are combined into a V-shaped structure; two battery slots and an area for installing a circuit board are separated by the two partitions, and the two batteries are installed in the two battery slots respectively.

[0012] Furthermore, a hanging rope portion is provided at the rear portion of the shell, and the hanging rope portion includes an end plate, and the left and right sides of the end plate are respectively connected to the rear ends of the two partitions through a connecting plate to form an integrated structure; the end plate and the two connecting plates form a triangular structure, which can improve the structural strength; a hanging rope is fixed through the end plate, and the utility model can be hung and carried by the hanging rope, which is more convenient to carry.

[0013] The utility model designs the entire product into a triangular structure, which is not only more beautiful and unique in appearance, but also the battery is arranged in a V-shaped structure, which can cooperate more compactly with the storage mechanism, making the overall size of the product smaller and more convenient to carry. At the same time, by arranging a roller in the shell, the data cable is pulled out after being wrapped around the roller. When pulling out or retracting, the data cable is supported by the rolling of the roller, thus avoiding direct friction with the shell. Not only is pulling out and retracting smoother, but also the roller can generate rhythmic sounds when pulling out, such as "rustling" or "da da da", which can bring a certain decompression effect to the user.
