On the surface, it is also for not affecting the active connection between the battery unit 2 and the power control device 1 or other battery units 2 .

Users can combine the power control device 1 and the battery unit 2 according to their own needs. They can assemble one battery unit 2 or multiple battery units 2. In theory, it supports the free combination of N battery units, so as to achieve the purpose of unlimited expansion. . Assume that the power of one battery is 5000MAH, two batteries are 10000MAH, three batteries are 15000MAH, and so on. As many batteries as you need. When the capacity of the battery becomes smaller after a long period of use, you can discard the used battery and replace it with a new battery instead of throwing away the entire mobile power supply, saving costs and protecting the environment.

In this embodiment, referring to FIG. 1 a , a light source 16 is further provided on the power control device 1 , and the light source 16 is electrically connected to the first contact feed point 15 .

The light source 16 is set on the power control unit 1 of the mobile power supply in order to use the light source as an emergency light in the dark. After the light source 16 is electrically connected to the first contact point 15, it can pass through the second contact point with the power control unit 1 22 is electrically connected to the battery unit 2 to obtain the electric energy for lighting. The light source can be arranged at any position other than the surface where the first contact point 15 is located.

Preferably, the light source 16 is an LED lamp.

LED uses a low-voltage power supply, and the voltage of a single LED is between 1.9-4V. It has the advantages of energy saving, long life and good applicability. Because of the small size of a single LED, it can be made into any shape. In addition, the response time of LED is short, which is the response time of nanosecond level, while the response time of ordinary lamps is millisecond level. LED is a very suitable choice for emergency lighting. The LED is colorful, the luminous color is pure and environmentally friendly, there is no harmful metal, and the waste is easy to recycle, so the LED lamp is selected as the light source 16 in this embodiment.
