The rotating pin 20 is rotatably arranged on the back of the housing 10 and can be rotatably received in the first receiving slot 11. The rotating pin 20 and the main control circuit board 60 are arranged on one side of the energy storage module 50. The rotating pin 20 is used to be inserted into the power supply device, connected to the mains voltage, and transmit the electric energy to the main control circuit board 60. The relevant circuit on the main control circuit board 60 converts the mains voltage into a lower voltage to charge the energy storage module 50. When the energy storage module 50 needs to be charged, the rotating pin 20 can be rotated to the charging position. When the energy storage module 50 does not need to be charged, the rotating pin 20 can be rotated to the receiving position, that is, rotated to the first receiving slot 11, which is conducive to the miniaturization of the mobile power supply.

[0031] At least one connection plug 30 is electrically connected to the energy storage module 50, and each connection plug 30 can be correspondingly received in a second receiving slot 12, and the connection plug 30 is used to connect an external electronic device. The connection plug 30 can connect an external electronic device, transmit the electric energy of the energy storage module 50 to the electronic device, and charge the electronic device. When the electronic device does not need to be charged, the connection plug 30 can be stored in the second receiving slot 12, and the user does not need to carry an additional charging cable, which is very convenient to use.

[0032] The display screen 40 is electrically connected to the energy storage module 50, and is disposed on the front of the housing 10, and is located on the side of the energy storage module 50 away from the rotating pin 20 and the main control circuit board 60. The display screen 40 is used to display the status information of the mobile power supply. The status information of the mobile power supply that can be displayed on the display screen 40 may include the charging voltage, charging current, power, and power of the mobile power supply. The display screen 40 can specifically be a liquid crystal display screen 40, a diode display screen 40, and the like. In this embodiment, a liquid crystal display screen 40 is preferably used, which has low energy consumption, is lightweight, has high resolution, a wide viewing angle, and a long service life.

[0033] The present application arranges an energy storage module 50 and a main control circuit board 60 in a shell 10, a rotating pin 20 is connected to the main control circuit board 60 and arranged on one side of the energy storage module 50, and a first storage groove 11 and at least one second storage groove 12 are provided on the back side of the shell 10, so that the rotating pin 20 and the connecting plug 30 are stored on the back side of the shell 10, which is conducive to the miniaturization of the mobile power supply; the display screen 40 is arranged on the front side of the shell 10 and is located on the side of the energy storage module 50 away from the rotating pin 20 and the main control circuit board 60, so that the distance between the rotating pin 20 and the main control circuit board 60 and the display screen 40 is increased, and the influence of the heating of the rotating pin 20 and the main circuit board 60 on the display screen 40 is reduced, and the service life of the display screen 40 is increased, thereby increasing the service life of the mobile power supply. At the same time, the user can connect an external electronic device through the connecting plug 30 to charge the electronic device without carrying an additional charging cable, which is convenient to use.

[0034] In addition, the display screen 40 is located on the front side of the shell 10, and the rotating pin 20 is located on the back side of the shell 10. When the mobile power supply is charged using the rotating pin 20, the back side of the shell 10 is in contact with a wall or a power supply device, and the user can observe the status information of the mobile power supply through the display screen 40 on the front side of the shell 10, such as the charging voltage, charging current, and whether it is fully charged.

[0035] The connection plug 30 may be a type-C plug, a Lightning plug, a Micro USB plug, or other plugs that can be adapted to the charging port of an external electronic device. The number of the connection plugs 30 may be one, two, three, or more than three. The plug types corresponding to the two or more connection plugs 30 may be the same or different. The user may set the number and type of the connection plugs 30 according to actual needs.

[0036] In this embodiment, three connection plugs 30 are preferably provided. The three connection plugs 30 are respectively a type-C plug, a Lightning plug, and a Micro USB plug. They can be adapted to three electronic devices with different charging ports. Three electronic devices can be charged at the same time, which is convenient to use.

The second receiving grooves 12 are arranged along the length direction of the housing 10, allowing the second receiving grooves 12 to have a longer length, thereby allowing the connecting plug 30 to have a longer length. The three second receiving grooves 12 occupy a larger area. By arranging the first receiving groove 11 and the three second receiving grooves 12 on the back of the housing 10, the front and side surfaces of the housing 10 are smoother, and the user can quickly identify and find the corresponding connecting joint and rotating pin 20, thereby improving the user experience.

[0041] The charging connector 32 can be connected to the energy storage module 50 through the connecting wire 31, allowing the charging connector 32 to have a certain distance from the energy storage module 50 and the housing 10. The user can place the housing 10 on the desktop and move the charging connector 32. There is no need to hold the mobile power supply when charging the electronic device, which is convenient to use. Since the connecting wire 31 and the charging connector 32 have different thicknesses, by setting the height of the bottom wall of the second groove section 122 to be lower than the height of the bottom wall of the first groove section 121, the connecting wire 31 and the connecting plug 30 of the connecting plug 30 can be stored in the corresponding groove section, and the connecting wire 31 and the connecting plug 30 are more closely attached to the bottom wall of the groove, and the back of the housing 10 is flat and will not bulge out to affect the feel of use.

When the connecting plug 30 is not in use, the connecting plug 30 is not easy to separate from the second storage slot 12.

[0046] Specifically, the first limiting assembly 13 includes at least two first limiting protrusions 131 symmetrically arranged on the two groove side walls of the first groove section 121, and the connecting wire 31 can be clamped and limited between the two first limiting protrusions 131 to limit the connecting wire 31 in the first groove section 121. The connecting wire 31 is clamped and limited by the two symmetrical first limiting protrusions 131, and the force on the connecting wire 31 is uniform.
