Abstract
The utility model discloses an emergency charger for handsets. The main body is a shell body. A gearing is arranged in the shell body. A drawing buckle passes through the shell body and is connected with the gearing. The gearing is arranged on a bracket and fixed with a circular magnet through a rotation shaft. A rotor is wound with coil and fixedly arranged in the circular magnet. The circuit of the charger is composed of a rectification circuit, a regulation circuit and an output circuit which comprises a generating circuit sequentially connected with a rectification bridge. The drawing buckle drives the gearing rotate, so the rotor of the generator carries out the magnetic force line cutting movement in the circular magnet. Thus, an AC output voltage is generated and provides the mobile phone a 12V working voltage through the rectification and the voltage regulation. At the same time, the AC output voltage is supplied to an LED through a switch and a charging capacitor for provide the lighting service in the dark. When the power is out, the drawing buckle can be drawn by hand for providing the charging or lighting service for the handset. The charger can be hanged on a key ring. The emergency charger for handsets is portable, convenient and practical.
