[0002] Existing rechargeable power supply devices are of a great variety due to different uses, for example: there are power supplies that utilize solar energy or wind energy or mains power, can be used for charging power supplies for mobile phones, or are used for computers, radios, players and various low-voltage batteries. External power supply for energy-saving lamps and other electrical appliances, but these charging power supply devices are all low-voltage and low-capacity DC power supplies, which are difficult to use for various lighting fixtures that use AC power, and include refrigerators, hair dryers, electric fans, TVs, and even air conditioners. External power supply for large household appliances

Due to the improvement of living standards, various household appliances are very popular in modern families. However, in summer, power outages or power outages (due to thunder or power grid maintenance) are often encountered due to power shortages, and residents' lives are seriously affected. Therefore, although some units currently Residential communities and residential areas have to purchase diesel generators as temporary power supply equipment, but most households cannot and unconditionally purchase this kind of emergency power supply equipment, so they can only endure the suffering of power outages or power outages helplessly
