More friendly.
按,現代科技日新月異,目前幾乎每個人都有行動設備,例如智慧型手機或是平板電腦,此種行動設備內的電力來源大多由鋰電池、鋰聚合物電池提供,但由於行動設備會不斷的接收與傳輸訊息,導致耗電量相當的大,當行動設備在戶外沒電時,使用者即需要以行動電源進行充電,讓行動設備能夠持續使用下去,而目前的行動電源通常還是以有線的連接方式為主,因此,使用者在使用行動電源的同時,也要準備好充電的線材才能充電,係較為不便利。 According to modern technology, every day, almost everyone has a mobile device, such as a smart phone or a tablet. Most of the power source of such mobile devices is provided by lithium batteries or lithium polymer batteries. Receiving and transmitting messages results in considerable power consumption. When the mobile device is out of power, the user needs to use the mobile power source to charge the mobile device for continuous use. The current mobile power source is usually wired. The connection method is mainly used. Therefore, when using a mobile power source, the user must also prepare a charging cable to charge, which is inconvenient.

由前案專利可知,目前行動電源已經有無線的充電技術,可增加使用上的便利性;然而,行動電源本身也需要充電才能提供足夠的電力給行動設備使用,一般行動電源都是透過市電或外部其他電源進行充電,而目前市電的生產仍是以石化燃料與核能為主,其對環境會造成相當大的汙染。爰此,如何提供一種讓使用者便利使用的行動電源,且其能夠以較乾淨的燃料進行充電,以保護環境減少污染,此變成為發明人所思及之方向。 According to the patents in the previous case, the current mobile power supply already has wireless charging technology, which can increase the convenience of use; however, the mobile power supply itself also needs to be charged to provide sufficient power for mobile devices. Generally, mobile power supplies are powered by city power or Other external power sources are used for charging. At present, the production of commercial power is still mainly based on petrochemical fuels and nuclear energy, which will cause considerable pollution to the environment. Therefore, how to provide a mobile power source that is convenient for users and can be charged with a cleaner fuel to protect the environment and reduce pollution has become a direction that the inventors thought about.
