The housing is provided with terminal pieces for adjusting the position. The terminal pieces may be moved by fingers from the bottom of the housing. The second locating surface of the slide cover is in tight contact with the first locating surface when the charger is not used, thereby creating a complete contour of the charger without any gaps. In charging, the slide cover is pushed outwards over a certain distance according to the dimensions of batteries such that a charging space is created between the second locating surface and the first locating surface of the housing.
