Abstract

A charging device using magnets is disclosed. The charging device using magnets includes a sleeve and a charging pad. The sleeve includes a connector connected to the charging terminal of a mobile terminal, and a plurality of magnetic terminals connected to the connector. The charging pad includes magnetic electrodes which magnetically come into contact with the respective magnetic terminals of the sleeve, and supplies charging power to the magnetic terminals using the magnetic electrodes. The magnetic electrodes of the charging pad are configured such that magnetic forces are attenuated due to magnetic fields of coils or such that repulsive forces are generated between the magnetic electrodes of the charging pad and the magnetic terminals of the sleeve which come into contact with the magnetic electrodes.
