The "pinch" that Basher uses to knock out Las Vegas's power is based on a device called the z-pinch, which creates a burst of energy (mostly x-rays) by using a magnetic field that "pinches" a column of charged gas particles. However, the movie departs from science in several ways: first, a real z-pinch is much too large to fit in the back of a van; second, a pinch can't create energy out of nowhere, and would need a power source much greater than Basher's "score of car batteries" or anything that would fit inside a van; third, even with such a power source, the electromagnetic pulse (EMP) generated by a real z-pinch is barely powerful enough to knock out an electronic device across a room. In fact, under current science, the only thing capable of generating a city-wide EMP is a genuine nuclear explosion.
