Why Do I Need EMP Shield?

  • The Government has released an EMP Executive order & Homeland Security is urging people to get prepared quickly!
  • Although the grid may be down, your electrical equipment and home will still be functional if you have EMP Shield. 
  • EMP Shield will ensure your vehicle operates after an EMP helping you get home, save family members, or even get supplies while others cannot.
  • Your home will be 100% protected from lightning saving you thousands of dollars and months of time if you are hit with lightning.
  • If you have a solar system or generator, you will have power and functional equipment while others do not!

How Has This Been Tested?

Isn’t a nuclear explosion required to create an EMP?

The threat of an EMP is the large amount of electricity that is induced into conductors that generate heat and can be destroyed.  There are only a few testing facilities in the world capable of producing the same amount of electricity that an EMP produces. 

EMP Shield has been rigorously tested at the Keystone compliance facility which is a federally approved testing facility that is used to conduct many of today's most advanced and comprehensive technological tests. Out testing and evaluations conducted at the facility were documented in depth to show the true ability and durability of the EMP Shield. Below you will find the complete Keystone Compliance testing results of the EMP Shield.


How Does EMP Shield Work?

EMP Shield will protect all the electronics and equipment connected to your electrical system.

This is accomplished by shunting (shorting) the over voltage coming in from the grid and the induced voltage that is collected within your home.

Whether the source of electrons are from within your home or coming into your electrical system from outside the home (the grid), the Shield will see the surge and protect your electrical system. Our technology reacts in less than 1 billionth of a second. Since the shunting is completed incredibly fast, the over voltage is drained away from the equipment before the voltage can rise high enough to damage any equipment. We call this new technology SightSpeed™

    This comment is for customer service and simplicity in the installation. I have not had an incident to have had the device protect me as of yet, and I hope never to have such.

    Seriously, this was the BEST customer service I have EVER experienced!!! I am in awe of the genuine care and old fashioned way of taking care of business that I have missed. It is refreshing to know people and companies like this still exist, especially in the industry of something so essential and life-saving! I do not give reviews lightly and rarely provide them. However, I need to say Thank You So Much, Andrew, for being a breath of fresh air in this ever-changing world!

    Further, I called late at night after I ordered online to see if I could add to my order and ask a question, and I got an answer by a human, Andrew. He was so amazing, adjusted my order, and shipped it out right away. I got the box within 24 hours of my actual order!

    I have been able to install the devices purchased. The home models arrived, and I was able to connect the one device on the customer side of the main line breaker; my service company would need to be there to shut it off if on the service side, despite an electrician. I was very cautious about installing anything to the electrical panel, yet I was encouraged as the directions were so simple. I, NOT an electrician, with minimal electrical experience, installed the device closest to the main breaker off of two, twenty-amp breakers connections, and the ground, so easily. I had an electrician check my work afterward, to be sure, and it was perfect; amazing! Simple directions that are simple because it is simple to do; wow! It took me only minutes to install the two vehicle models on vehicles with top mount batteries; the instructions with pictures were so concise and precise.

    I ordered again, at a later date, for my family. You need to know a few things before you order for others. Do the vehicles have a top or side mount battery? It matters, as some domestic automobiles have side mount batteries and have different posts or means of connecting to the battery from the vehicle. This situation is easy to fix by changing the connections with different washer type connectors to have it fit flush. The directions are the same, however, aside from the connector size, as post sizes and means of connections are different, and obviously that it is on the side instead of the top, the other way around.

    The next important thing you need to know before you purchase for your loved ones is, for their home, do they have a flat electrical panel or a box? This distinction matters for the cord length, and to see the lights. The other thing they will need is enough room on the panel to insert it on 2, 20 amp breakers, which they should have already, and if for some reason the circuit board does not, they will need them before installation. I am not an electrically inclined person, so please excuse the down to earth language.

    Another important thing to know for an RV model is the amps. You may need to call and have one custom made, which they will gladly and quickly do.

    The last recommendation is for the solar/wind, or generator. There are a few things you need to contact the customer support for these applications because the device you order needs to be made specific to the amps your generator can handle. The solar/wind placement for the model is different, but also very easy to install. Regarding the generator that connects to your service panel, not from a solar panel, or wind, or battery, but one that connects to a pre-installed cord so you can use the generator to connect to your circuit-panel so that you can run the house or portions of such.

    My loved ones hired an electrician to install the device on their home to be satisfied and feel more secure. They protected the domestic vehicles with vehicle models, even with side mount batteries themselves.

    All in all, this was a very wise investment, and, I hear more and more daily about the reasons that I purchased the products in the first place: protection and peace of mind! I did my research and I chose the best protection! Thank you, EMPshield Team!

    Love the feeling of knowing life can go on with this jewel. Would not be without it, especially for peace of mind sake. THANKS

  15. Michael Woldman (verified owner)

    Rapid shipment of product and good instructions/wiring diagram on how to safely install.

  16. Kenneth (verified owner)

    This product came packaged very well. Best packing I’ve seen. (#5 rating)
    Phone Friendliness and prompt phone answer (#5 rating)

    Help over phone get’s a ‘5’ for wanting to help and a ‘3’ for not calling me back.
    4 wire connectivity is simple but the Instructions get a “2” at best.

    IF you have an older outdated “pushmatic” (Push type) breakers, then you better have 2 free in the box because finding “pushmatic” breakers can be a problem leaving you with a nice unit just ‘waiting’ to be installed.

    My point:
    you’ll pretty much NEED a real electrician to do the Connecting due to the Joke called “Instructions”. I paid $80.

    WOULD I recommend this to a friend still?
    (This sort of Insurance is just too essential NOT to have installed today!)

    YES! Get one! I told all my friends and on course they just sit and stare and sometimes blinked before changing the subject! LOL

  18. Susan Morgan (verified owner)

    It didn’t take long to arrive after placing the order. Simple to install and now I am confident I will be prepared when an EMP of any sort happens. Be prepared is always a good motto.thank you.
