Hand-held power self-generating portable cellphone charging device

Abstract

The invention provides a hand-held power self-generating portable cellphone charging device. An electric control device which is electrically connected with the rotor shaft of a generator is arranged in an ABS (Acrylonitrile Butadiene Styrene) shell; the electric control device comprises a rectifier-filter circuit, a voltage stabilizing circuit and a storage battery pack, all of which are orderly connected with each other; a shunt circuit is arranged at the output end of the storage battery pack; an LED (Light Emitting Diode) light emitting branch circuit, a cellphone charging circuit and an electric quantity testing circuit are arranged in the shunt circuit; the LED light emitting branch circuit is connected with an LED lamp bead strip arranged at the front end of the ABS shell; the cellphone charging circuit is connected with a USB (Universal Serial Bus) charging port arranged at the rear end of the ABS shell; the electric quantity testing circuit is connected with an electric quantity display screen arranged on a sidewall of the ABS shell. The hand-held power self-generating portable cellphone charging device is simple in structure and reasonable in design, and capable of charging a cellphone in an emergency by being added with corresponding circuits based on the charging principle of the traditional hand-held power self-generating flashlight, and therefore, the troubles of people can be avoided.
