[0002] With the popularity of electronic devices and the improvement of their intelligence, mobile power has become one of the indispensable electronic devices in modern people's daily life. Mobile power, also known as portable charger or power bank, is a device that can store electrical energy and provide power to other electronic devices when needed. It usually uses rechargeable lithium-ion batteries as energy sources, and realizes the storage and release of electrical energy through internal charging and discharging circuits.

[0003] Traditional mobile power supplies mainly focus on improving charging capacity and charging speed to meet users' power needs in different scenarios. However, with the advancement of technology and the diversification of consumer needs, the simple charging function can no longer meet user needs.

[0004] Disadvantages of existing mobile power supplies:

[0005] 1. Single function: Although existing mobile power supplies already have basic charging functions, they often lack other additional functions. Outdoors or in emergency situations, users may also need other functions such as lighting and emergency distress signals, but existing mobile power supplies often cannot provide these additional assistance.

[0006] 2. Inconvenience in use: Some mobile power supplies are not user-friendly in design and use. For example, the power cord is easy to get tangled or lost, or the charging interface is not universal, requiring users to carry multiple charging cables. These problems bring inconvenience to users.

[0007] 3. Inconvenient to carry: Although the size of mobile power banks is relatively small, it is still a burden for some users who need to carry them frequently. In addition, some mobile power banks are not equipped with lanyards or fixing devices, which can easily slip or get lost during carrying. Utility Model Content

[0008] The purpose of the utility model is to provide a multifunctional mobile power source to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional mobile power supply, comprising a shell and a power cord, a lighting screen is fixedly installed on the top of the shell, a knob switch is threadedly connected to the left end of the top of the shell, and a leather lanyard is sleeved on the outer side of the power cord.

[0010] A shell cover is fixedly installed on the bottom of the shell, and a charging interface is arranged in the middle position of the left side of the shell.

[0011] A PCB board is fixedly installed in the middle of the shell, and batteries are arranged on both sides of the PCB board.

[0012] One end of the power cord is clamped on a plug-in end fixedly arranged on the leather hanging rope, and one end of the power cord is clamped in a limiting sleeve fixedly arranged on the leather hanging rope.

[0013] A U-shaped ring is fixedly connected to the rear end position of the left side of the shell, and the U-shaped ring is connected to the leather lanyard through an active buckle.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Multifunctionality: It integrates lighting and charging functions to meet the needs of users in different scenarios.

[0016] 2. Easy to carry: Through the design of leather lanyard and U-shaped ring, the mobile power bank can be conveniently hung on a bag, wrist, etc., making it easy to carry and use.

[0017] 3. High safety: The brightness of the lighting screen and battery charging are controlled by a knob switch to avoid potential safety hazards caused by misoperation. At the same time, the charging circuit on the PCB board also has overcharge, over-discharge, over-current and other protection functions to ensure the safe use of the mobile power supply.

[0018] 4. Easy to operate: The design of the knob switch allows users to adjust the brightness of the lighting screen and control the battery charging through simple rotation, which is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
