However, the use of electronic products is inseparable from electricity, and people's demand for electricity is increasing day by day. It can be said that people's lives are inseparable from electricity. Once they are out of the power grid or the power is cut off, these electronic products will be paralyzed. At this time, the power supply of electronic products has become a problem faced by people.

[0003] At present, there are two main ways to solve this problem. One is to use diesel or gasoline generators to generate electricity, and the other is to use energy storage equipment to store energy for power supply. Using generators to generate electricity is costly, noisy, and consumes diesel or gasoline during the power generation process, causing noise pollution and environmental pollution.
