Abstract
A charger is adopted to charge a first-type battery pack and a second-type battery pack, each type of battery packs having an insertion portion whose shapes are different. The charger is provided with a housing having a battery pack socket for inserting the battery packs. The battery pack socket has a shape that allows the insertion portion of the first-type battery pack and the insertion portion of the second-type battery pack to be inserted thereto selectively in a prescribed attitude. A pair of output terminals that output charging power is disposed within the battery pack socket. The pair of output terminals is electrically connected to the first-type battery pack when the insertion portion of the first-type battery pack is inserted into the battery pack socket in the prescribed attitude. Likewise, the pair of output terminals is electrically connected to the second-type battery pack when the insertion portion of the second-type battery pack is inserted into the battery pack socket in the prescribed attitude.
