The EMP Stopper is a multi-purpose transient protection device. It protects your vehicle against lightning, surges as well as EMP charges. It is easy to install by plugging it in under the under the drivers side dash area of the vehicle. The device is packed with transient voltage suppression components which have ultra high reliability (AEC Q101 qualified), have a reaction time of less than 1 picosecond, and can suppress up to 10,000 Watts. Excellent for fast protection in temporary vehicles.

How can the EMP Stopper be effective against an EMP when it’s so small?
The danger to vehicles from an EMP is mainly the high voltages that are introduced on the wiring from E1 and E2. Those transient voltages are extremely brief in time (from nanoseconds to microseconds) and can therefore be suppressed using small devices. This is distinctly different than the case with homes, which would also experience a powerful E1 current surge from the power grid.
Is it ok to use multiple EMP Stopper devices in one vehicle?
Yes, putting EMP Stoppers at multiple points in your vehicle does a better job shunting away the unwanted energy.
Does the EMP Stopper protect a vehicle even when the vehicle is powered off?
Yes, the EMP stopper provides transient protection even with the ignition switch turned off because wiring assemblies can still receive damaging energy. The EMP Stopper continues to act as a high-frequency energy absorber even when the vehicle is off. The module is always connected to your vehicle wiring, ensuring the Stopper always catches any surges across the wiring. The green indicator light uses extremely low current and ensures the module is connected and working.
Can the light on the EMP Stopper drain my battery?
No, the light uses extremely low levels of power, approx 4mA, which is much less than car radios and other accessories. This amount of current draw is negligible.
Can I use the EMP Stopper on another vehicle?
Yes, the EMP stopper can be used on any 12 Volt vehicle manufactured on and after 1996.
Will the EMP Stopper interfere with any vehicle systems?
No, the EMP Stopper monitors the wiring for voltage surges and only activates once one is detected. It then shorts this energy in a fraction of a second, protecting the vehicle electronics. Once the surge has been neutralized, the module returns to normal, ready for the next surge.
