However, the use of electronic products is inseparable from electricity, and people's demand for electricity is therefore increasing daily. It can be said that people's lives are now inseparable from electricity. Once disconnected from the power grid or during a power outage, these electronic products will be paralyzed, and at this time, power supply for electronic products becomes a major problem for people.
[0003] Currently, the main methods to solve this problem are as follows: one is to use diesel or gasoline generators to generate electricity, and the other is to use energy storage devices to store energy for power generation. However, using generators to generate electricity is costly, noisy, and requires diesel or gasoline to generate electricity, causing noise pollution and environmental pollution.
[0004] Currently, the most commonly used energy storage devices include portable power banks and energy storage power supplies. Portable power banks typically only have a single 5V input and output, which limits their application scenarios and makes it difficult to meet people's diverse needs. Most energy storage power supplies are too industrialized in design and mostly use lead-acid batteries as energy storage batteries, resulting in excessive size and weight that far exceed the requirements of portability, making them unacceptable to people. Therefore, it is necessary to design a portable energy storage power supply. Utility Model Content
