Abstract: The auto powered jack apparatus provides for selective telescopic extension of the jack shaft. The telescopic jack is especially useful for lifting an auto. The jack is in removable communication with either the air compressor or the electrical inverter, both powered by a cigar lighter plug removably fitted into a cigar lighter. The apparatus also provides for wrenching any given object with the powered handgun shaped wrench. The jack is omni directionally operated so that objects may be separated as chosen and other functions performed with the jack.
