This creation is a kind of "AC/DC rechargeable mobile phone cell". A charger is installed in a case which is composed of a panel and a back case body. The panel has a concave cabinet which can hold an eversible and locatable plug plastic body. It makes the back end of the plug's electric insertion piece pressing on the elastic conducting piece closely. Consequently, the conducting quality~is improved. A dual-color LED and the rechargeable cells are connected across the charging circuit. When the charging voltage is lower than reference voltage, the red light of the dual LED is lighten. When the cells are fully charged, the green light of the dual LED is lighten and a low potential is output to an optic-coupling switch from a linear IC to stop charging. And then, the energy is saved and the cell's life is prolonged |
