  • 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 rigorous 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™

  6. Noah T. (verified owner)

    The only thing I can review at this point is the service. All questions were answered. Shipping occurred next day. Terms are good and I’m told for warranty and insurance to take effect I need an electrician to install at the house and generator. No problem as I intended to do that anyway. Hope I never need them but I throw money at insurance every day so no difference except, if it’s needed, these could literally be life savers.

    Given the state of the world and the fact that our home is in the country and is a likely lightening target we decided to invest in this product. The purchase was made via phone and was painless. the product shipped the next day. Employee Jessica was super helpful. We hope we never have to test the product in the “real world” but we agree that it will give us much peace of mind. Thanks!

    We really appreciate EMP Shield’s superb support for the retired military customer wanting to prepare their home and cars for all contingencies. Erika took my call and was extremely helpful and professional getting our entire order processed. She followed up and kept us informed every step of the way! We have been notified by email that the item quickly shipped by UPS, and we look forward to receiving it by 3 April 2023. We hope to have it installed shortly thereafter. Thank you!
