         2 . The charger according to  claim 1 , wherein the bottom circumferential portion including the finger hook portion protrudes to an outside of the main body housing further than the bottom center portion. 
     
     
         3 . The charger according to  claim 1 , wherein the finger hook portion is provided over an entire circumference of the bottom circumferential portion. 
     
     
         4 . The charger according to  claim 1 , further comprising a center step portion in the bottom center portion, the center step portion protruding to the outside of the main body housing so as to expand an internal capacity of the main body housing. 
     
     
         5 . The charger according to  claim 4 , wherein the center step portion protrudes to the outside of the main body housing in a same height as the bottom circumferential portion. 
     
     
         6 . The charger according to  claim 1 , further comprising a leg in each of four corners of the finger hook portion,
 wherein the charger is placed on a worktable via the leg.   
     
     
         7 . The charger according to  claim 1 , further comprising a pair of charger hook portions on the bottom surface so as to mount the charger on a wall surface in a wall-hanging state. 
     
     
         8 . A charger used for charging a rechargeable battery, comprising:
 a main body housing including an upper housing and a lower housing;   a bottom surface formed in the lower housing;   a bottom center portion provided in the bottom surface such that a plurality of charger function parts are mountable thereon in an interior of the main body housing;   a bottom circumferential portion provided in the bottom surface, the bottom circumferential portion surrounding the bottom center portion and including four sides of the bottom surface; and   a finger hook portion that is provided over an entire circumference of the bottom circumferential portion and protrudes to an outside of the main body housing further than the bottom center portion, thereby increasing efficiency in hooking a finger thereon compared to on the bottom center portion.   
     
     
         9 . The charger according to  claim 8 , further comprising a center step portion in the bottom center portion, the center step portion protruding to the outside of the main body housing so as to expand an internal capacity of the main body housing. 
     
     
         10 . The charger according to  claim 9 , wherein the center step portion protrudes to the outside of the main body housing in a same height as the bottom circumferential portion. 
     
     
         11 . The charger according to  claim 10 , further comprising a leg in each of four corners of the finger hook portion,
 wherein the charger is placed on a worktable via the leg.   
     
     
         12 . The charger according to  claim 11 , further comprising a pair of charger hook portions on the bottom surface so as to mount the charger on a wall surface in a wall-hanging state. 
     
     
         13 . A charger used for charging a rechargeable battery, comprising:
 a main body housing including an upper housing and a lower housing;   a bottom surface formed in the lower housing;   a bottom center portion provided in the bottom surface such that a plurality of charger function parts are mountable thereon in an interior of the main body housing;   a bottom circumferential portion provided in the bottom surface, the bottom circumferential portion surrounding the bottom center portion and including four sides of the bottom surface;   a finger hook portion that is provided over an entire circumference of the bottom circumferential portion and protrudes to an outside of the main body housing further than the bottom center portion, thereby increasing efficiency in hooking a finger thereon compared to on the bottom center portion;   a leg in each of four corners of the finger hook portion, via which the charger is placed on a worktable; and   a pair of charger hook portions on the bottom surface so as to mount the charger on a wall surface in a wall-hanging state.   
     
     
         14 . The charger according to  claim 13 , further comprising a center step portion in the bottom center portion, the center step portion protruding to the outside of the main body housing so as to expand an internal capacity of the main body housing. 
     
     
         15 . The charger according to  claim 14 , wherein the center step portion protrudes to the outside of the main body housing in a same height as the bottom circumferential portion.
