Description

technical field [0001] Embodiments of the present invention relate to the field of mobile power supplies, in particular to a self-generating mobile power supply. Background technique [0002] Mobile power is playing an increasingly important role in daily life. It can provide people with the necessary power support in an emergency. When the mobile phone is out of power, the mobile power can be used for emergency charging and prolong the battery life of the mobile phone. , Provide power support for lighting lamps through mobile power supply, light up lighting lamps, and provide many conveniences for people's lives. [0003] However, the traditional mobile power supply needs to be connected to the power supply for charging in advance to ensure emergency power supply when necessary, and the capacity of the ordinary mobile power supply is small, the battery life is weak, and the power will be exhausted soon, and it is inconvenient to use it outdoors. The power supply is charged...
