Problems solved by technology

However, due to more and more functions of mobile phones, the software and hardware to realize these functions need to consume a large amount of built-in power of mobile phones, especially for display, camera and positioning, which consume a lot of power, which makes the battery life of mobile phones seriously insufficient. , Therefore, many mobile phone users will be equipped with one or more mobile power banks to keep the mobile phone working continuously when they go out
[0003] In the prior art, almost all mobile power supplies sold on the market have a fixed structure, fixed batteries and fixed rated power. Such a design makes the mobile power supply unable to continue to provide electric energy when the power of the mobile power supply is exhausted, thereby Inconvenience to users, especially long-distance travelers
Moreover, mobile power supplies on the market generally use lithium-ion batteries, lithium-ion polymer batteries or 18650 lithium-ion batteries as electric energy storage media. However, the above three batteries have safety hazards suc
