Background technique

With the development of science and technology, people's demand for electronic products is increasing day by day. Regardless of home, going out, work, entertainment, electronic products have almost entered every aspect of people's life, so people have to pay attention.

In addition to providing the most powerful functions within the limited volume of electronic products, more and more attention is paid to the portability of electronic products. To get the assistance of electronic technology at any time to make life more convenient. the

Continuing from the above, due to the emphasis on the portability of electronic products, various manufacturers have devoted themselves to studying the technology of miniaturization of electronic products, and have achieved quite fruitful results in a short period of time. However, electronic products also have inherent limitations, which on the other hand limit the rapid development of electronic technology. This innate limitation mainly comes from the power supply. When electronic products are used, they must rely on electric power to provide drive. When the power is insufficient or interrupted, even the most powerful electronic products are useless. Since traditional electronic products are mainly used in fixed places and rely on indoor power supply, the problem of power supply is often ignored in use. But for portable products, every milliampere of electricity is a very precious resource. Although various manufacturers are also working hard in the direction of low energy consumption, they are still unable to make effective breakthroughs due to the limitation of power storage technology. Therefore, under the limited battery space, there is often a temporary power interruption problem. Especially for electronic products that are getting smaller and smaller, their batteries are also reduced accordingly, making it more difficult to store electricity, thus limiting the use of portable electronic products. the

For this reason, some people will carry chargers when they go out, but the size and shape of the chargers are not easy to store, and the chargers of each portable electronic product may be incompatible with each other. If a person has more than two (including) It is really inconvenient to carry some miscellaneous items every time you go out. Or someone will carry a backup power source such as a second battery or a small generator when they are out and about. However, these devices are not frequently used products, and they take up limited personal carrying space, so most people do not or are inconvenient to carry them with them. Even if they want to carry them, they may forget to carry them due to temporary haste, so their application rate is not high. the

It can be seen that the existing portable backup power supply device still has shortcomings, and needs to be improved urgently. the
