When the amount of current of the battery unit 110 decreases, a warning light is turned on on the display unit 112 so that the user can detect the amount of current. The user can expand the folding solar panel 120 and charge the solar panel 120 through the sunlight. At this time, the user can adjust the angle of the hinge 121 of the folding type solar panel 120 according to the angle of incidence of the sunlight to form an appropriate angle of light receiving angle.

When the solar panel 120 receives the sunlight, a current generated in the solar panel 122 is rectified to a proper level in the charging circuit unit 130 to charge the battery cell of the battery unit 110 . When the charging is completed, the charging circuit unit 130 senses this, and prevents overcharging of the battery unit 110 by blocking the current supplied from the solar panel 1220. In a state where the solar battery is continuously lacking, The charging circuit unit 130 turns off the current supplied to the power transmitting unit 111 and the charging circuit unit 130 interrupts the current supplied to the power transmitting unit 111. When the battery unit 110 is in the discharging state, Thereby preventing the battery 110 from being overdischarged.

At this time, if a user applies external DC power to the DC input terminal through a dedicated adapter or USB of a computer, the charging circuit unit 130 can charge the battery unit 110 with the DC power.

The rechargeable solar auxiliary battery 100, which has been charged, can be easily carried by folding the foldable solar panel 120.
