As competitions between people have been intensified significantly over time, people's pressure has been increased dramatically. In order to release the pressure, people would like to do outdoor exercises on holiday. People get used to the life with water and electricity supply and rely on electronic products. Therefore, it is really inconvenient to exercise outdoor without the electricity supply. In order to solve such inconveniency, an innovational product is invented, and the name is called "Inverter."

随著人与人之间竞争越越激，人们的生活压与日俱增，平时工作压大，到假日就想走向户外，藉由各种的休闲活动舒解生活压，然而平时过惯有水有电的生活，对生活家电已是相当依赖，而家电用的是市电，当假日到郊外，没市电，就会产生许多困扰，为消弭远城市所产生的种种，於是就产生一种电子产品-----Inverter，Inverter其主要作用即是将直电转换成交电，其用意乃是运用、船或飞机上之蓄电池
