The present invention relates to a charger capable of charging and storing a built-in main battery in a mobile communication terminal and a supplementary battery and supplying charged power of the supplementary battery to the mobile communication terminal or other devices. The charger of the present invention comprises: a case in which a first storage portion and a second storage portion are formed, wherein the first storage portion surrounds and fixes the rear and lateral sides of the mobile communication terminal and the second storage portion is formed on the rear of the first storage portion to fix the supplementary battery; and a charge control module which is integrally formed with the case and which monitors a charged state of the main battery installed in the mobile communication terminal and a charged state of the supplementary battery and supplies the charged power of the supplementary battery to the mobile communication terminal. The charger of the present invention stores both of the mobile communication terminal and the supplementary battery and can prolong the usage time of the mobile communication terminal with the charged power of the supplementary battery when the main battery of the mobile communication terminal is discharged. Also, the charger can charge the main battery of the mobile communication terminal of the same kind or of different kinds with the charged power of the supplementary battery and has a case function capable of protecting the mobile communication terminal against external impacts, thereby providing the convenience of use of the mobile communication terminal and improving the function as a charger. |
