Faraday DefenseDEFCON Vehicle - EMP Protection 12 Volt DC for Auto and Truck, Protection for Lightning, CME, Solar Flare, and Surge Protection

While of course I will not know if this will truly protect my vehicle if an EMP Event occurs, this seems to be the most thoroughly engineered device of its kind. I have to drive 22 miles to get to my bf if SHTF and I would prefer not to walk. Let's hope I never have to find out if it works!

Of all the questions to struggle to answer for someone else that might be considering buying this, "does it really work" is the most important, but in this case, the most difficult.I'd like to tell you that I installed it on my car, the bombs dropped, and a day later I was driving around the wasteland dodging super-mutants in my Lincoln while everyone else was stuck running away from the hordes of Deathclaws on their poor little feet.Except...I can't really say that. This is a product that is, for all intents and purposes, un-testable. Unless you have a giant lightning generator. I don't.I can tell you that it has a pretty green light. And it uses next to no power at idle.But when it comes to assuring you that this will, indeed, protect your car from an EMP? As much as I hate to lean on ambiguity, I simply don't know.Now, like the creator of this product, I do have a little bit of education in electrical engineering. And here is what my GUT tells me, just from what I know about electricity. My GUT tells me that your car battery is just as much an "absorber of EMP" as the Faraday Defcon. My instinct says that any EMP that the battery can't absorb isn't going to be absorbed by the Defcon, and the reason for this is a lack of path to ground and a lack of shielding around potentially effected circuits.When an EMP hits, it is a bubble of electromagnetic energy moving outward in space/time from a point of origin. This bubble or wave of electromagnetic energy is what causes a surge in electrical systems via INDUCTANCE. If inductance didn't exist, neither would damage from an EMP. As the wave passes through the car, the wave passes each and every wire and circuit. Any time an electromagnetic wave passes a wire, it induces a current (aka "inductance").The problem is while the coils of wire (inductors) in this can, indeed, absorb an induced current, what I don't think it CAN do is prevent the generation of inductance currents in the rest of the system. When that energy wave passes over the car's CPU, what prevents the EMP from inducing a current in the circuits OF the CPU?So...my INSTINCT...tells me that without shielding all the wires of your car, the Defcon is every bit as effective as your car battery at channeling away harmful EMP energy. And just like when your UPS protects your computer from a lightning strike (it's the batteries at work here, too, not the 'surge protector'), your car battery does most of the work in question.The question that remains is, do I recommend it? That's a difficult thing for me to say without a body of empirical evidence to back it up. For which there is none, save for the data that says "shielding works", but I've seen no other evidence that anything else does.I can't honestly say, buy it, it'll protect you from an EMP. I can't say that, so I won't say that. What I can say, with a degree of honesty I'm comfortable with, is that it's POSSIBLE that this works to provide some level of protection against an EMP. But that I'm not 100% convinced that it does. And I'll recommend that you do your own research, and be sure of your findings, before you commit.

Great item to have it installed, if it works, I don’t know, time will tell, but other than that all is well and easy to install! As a father I have to protect my family, at least I did something before it happens!!! Just saying I purchased four different ones and it’s 400$ each….

This brand produces several interesting products, from high quality dry bags to other EMP shielding items. This one feel well designed and sturdy, really i]easy to install in the Jeep. It’s small enough to fit pretty much about anywhere. Biggest challenge was finding the “right” place for it. Indicator light that allows you to know it is operational.Unsure of whether it really works without testing it or having an actual EMP event but considering they are more likely than one would expect, for example from a solar flare. It seems it is more logical to be prepared if possible. Especially since I would imagine that in a bad situation a vehicle being operational would be very important. I experienced one major natural disaster in my lifetime and a vehicle was absolutely critical.

Easy installation. Used for vehicle EMP protection.

It is not possible for a small device placed inside your vehicle to provide any sort of protection from an EMP. The only thing that could possibly help in these circumstances would be to put a Faraday cage around the sensitive electronics. This and any other device offering EMP protection is a scam.

Easy to wire up on the battery. Probably would help if your a handy person. I cant say for sure if this will stop a surge, but i have faith in the product, so far. Seems well made and came well pakaged. I have no reason to believe this product wouldnt perform properly, when needed. Im kind of hoping ill never need to find out, but atleast im more prepared, now. I would recommend based on the products build quality and expected functionality.
