PURPOSE: An aging test apparatus for a battery charger for a cellular phone or a switching mode power supplier is provided to not only check and detect the abnormality of equipment even by the change of time but also check all various kinds of equipments in an apparatus by switching. CONSTITUTION: A plurality of testing equipment connecting parts(110) is formed in one substrate to interlink a plurality of testing equipments. An equipment selection switch part(120) chooses a type for checking equipment which is connected in the testing equipment connecting part. A cable normality checking and voltage testing part(130) checks voltage output in the testing equipment which is connected in the test equipment connecting part, confirms disconnection between pins, or a short circuit, and/or the abnormality of ID resistance, and checks the change of the output voltage in the load of the testing equipment. MPU(Microprocessor Unit)(140) reads the switching status of the corresponding type and process an aging test, check the abnormality of the cable, and controls an output in an abnormality display part(150).
