Abstract:
1. A pocket safety hand-making electric power and rechargeable system for an electrical device, comprising: a manual power generation circuit which comprises a drive wheel which is adapted to be mechanically actuated for converting mechanical energy into a corresponding amount of electrical energy; an output interface electrically connected with said manual power generation circuit, wherein said electrical energy converted by said manual power generation circuit is transferred to said outer interface for operating said electrical device; and a safety control circuit which is electrically connected to said manual power generation circuit and said output interface, and comprises a first and a second reference source circuit, a first and a second comparator, a first and a second switch tube, and an indication circuit electrically connected to said first and said second comparator, wherein said first comparator is electrically connected to said first reference source circuit, said manual power generation circuit, said output interface and said second comparator, which is electrically connected to said second reference source circuit and said second switch tube, which is electrically connected with said first switch tube, such that said safety control circuit is adapted to control said electrical energy supplied to said outer interface when said manual power generation circuit is mechanically actuated.
