The present invention relates to an auxiliary battery using a solar cell and, more particularly, to a wireless charging solar auxiliary battery which can charge electricity using a solar cell as a charging source and charge power in a mobile phone by wirelessly transmitting the power to the mobile phone. To this end, the wireless charging solar auxiliary battery comprises: a battery unit (110) to receive a battery cell; a plurality of solar panels (120) connected to the upper end of the battery unit (110) to be rotated; a charging circuit unit (130); a power transmission unit (111) to transmit a current charged in the battery unit (110); a power control unit (140) to apply or block the current from the power transmission unit (111); and a power reception unit (150). According to the wireless charging solar auxiliary battery of the present invention, in providing an auxiliary battery pack including a solar panel which generates electricity using sunlight as an energy source, a folding solar panel is provided to reduce the volume thereof when carried, and the solar panel is expanded during charging to increase a light receiving area. Also, a mobile phone can be used without spatial constraints while being charged in a wireless charging manner. Also, an auxiliary battery can be charged using a separate adapter or USB power when it is difficult to charge the auxiliary battery using sunlight. |
