Description

technical field [0001] The invention relates to the field of electric bicycles, in particular to a reverse charging device for an electric bicycle and its mobile equipment. Background technique [0002] With the continuous promotion of urbanization and the continuous improvement of people's living standards, mobile devices (such as mobile phones, tablet computers and mobile power supplies, etc.) have become an indispensable part of people's lives. Due to the limited power storage of these mobile devices, mobile power supplies It is also not easy to carry. For most mobile phone users, they dare not go out if the battery power of the mobile phone is less than 50%, and they need to bring a mobile power bank to feel safe when they go out with 70% power. Travel charging has become a problem. On the other hand, people have also put forward more suitable requirements for means of transportation and travel methods. Therefore, electric bicycles are popular among the public because of...
