Surge Protector for Automobile Use

The automotive electrical system is a harsh environment. Normal voltages range from 9 to 15 volts, and even greater extremes. A jump start from a tow truck often pushes 24 volts down the wires. Stopping the engine can generates a spike up to 130 volts. And if a battery cable comes undone, the load dump can send 40 amps looking for somewhere to go. Automotive equipment, like the factory or after-market radio, is designed for this. But consumer electronics, especially the “cost minimized” imports, can easily be blown out of the water, or sunk by cumulative damage.”
