What To Store In A Faraday Cage For EMP Protection?


An EMP, or electromagnetic pulse, is thought to be a highly unlikely event. And it might be. On the other hand, no one can predict with any certainty one way or the other…if and when we get ‘zapped’ into a pre-high-tech age in which many or most of our ‘survival’ systems stop working (any system which depends upon electronics to keep on functioning).

While the follow-on effects of a devastating EMP event would be horrific, for those who are preparing for such an event – what are the electronic items that you would consider ‘saving’ in a do-it-yourself Faraday cage for life after the EMP?

Here are a few thoughts:

A quick review of potential EMP sources.
– Weaponized
– Natural occurring

I have written a number of articles regarding the topic of EMP. Long story short, nuclear weapons detonated at high altitude have the potential to instantly destroy today’s high-tech electronics within a debatable radius. It is conceivable that an EMP could be detonated from a weaponized orbiting ‘satellite’, or from a launched missile.

A naturally occurring EMP would be sourced from the Sun. While the technicality of the EMP effects are different (as well as the most vulnerable systems – e.g. the power grid itself), there is zero argument that this is a ‘regularly’ occurring event. Fortunately the time between events is not terribly frequent (to our own relativity), although many scientists say that a ‘1859 Carrington Event’ could occur sooner than we think… Space physicist Pete Riley, senior scientist at Predictive Science in San Diego, published an estimate in Space Weather Journal (FEB-2012) saying, The Earth has a roughly 12 percent chance of experiencing an enormous megaflare erupting from the sun in the next decade.

With that said, and for the sake of hypothesizing what we might protect in a Faraday cage, lets assume that most all electronic systems are ‘down’ (except those which may have been EMP ‘hardened’). If we presume that much or all electronic systems and the power grid is down, this will certainly influence the value (if any) on some of the items you may wish to consider for EMP protection…

My thoughts on a few potentially valuable items to protect in a Faraday cage:

2-way handheld battery powered radios for communications (GMRS/FRS/MURS). These do not rely upon any external systems for basic direct 2-way communications. After an EMP SHTF there will be significant value in local radio communications (for various reasons – especially security among a group).

CB Radio. Similar to the aforementioned 2-way radios, CB radios are also battery powered and may serve a useful comms purpose after EMP.

Portable Shortwave (plus AM/FM) radio. Following an EMP event, not everyone may be ‘down’. There will likely be regions and/or other parts of the world that will not be affected. Using an ordinary battery powered SW/AM radio will provide the possibility of gaining news and information.

Ham Radio receivers or transceivers. Again, most all of these units have the ability to be powered by battery, and a ‘Ham Radio’ has the ability to transmit and receive all over the world without the requirement for any external systems.

Solar battery charger system. The ability to recharge common batteries for the electronic devices that you’ve protected – is essential for ongoing operation.

LED flashlights. Some say that even your LED flashlights may be vulnerable to EMP effects, so storing a few in the Faraday cage may be smart.

I could go on and on with more brainstorming of items to consider for a Faraday cage, but I want to hear what you have to say too…

What are your ideas?

  1. When talking about storing a Ham Radio for long distance communications it is important to note we are talking about HF (High Frequency) radios. The the VHF (Very High Frequency) UHF (Ultra High Frequency), 900mhz and 1200mhz ham radios are for line of sight and repeater use communications.

    HF radio bounces the signal off of the ionosphere for long distance communications. An HF transceiver is also a short wave receiver. If you purchase a HF transceiver you do not need a short wave radio. A HF transceiver can receive in all modes, AM,FM,CW (Morse Code), Sideband (Upper and Lower)and RTTY. Many lower price short wave receivers do not have this capability.

    If you are looking for something small, inexpensive that does it all and only weighs 5 pounds, I would consider the Yaesu FT-857D. In addition to putting out a full 100 Watts on HF frequencies, this radio also receives and transmits VHF and UHF (2 meters and 70 Centimeters) Almost all modern Ham radios operate on 12 volts so you will need a power supply or 12 volt battery that would best be charged with a solar panel and small charge controller.

    When it comes to an antenna for HF radio, a simple multi band wire antenna up in the trees works very well and they are very inexpensive.

    For a Faraday Cage, I use a 55 Gallon steel drum with a steel overlapping lid and steel locking band. These can be found on Craigs List. I line the drum with 1/4″ rubber mat material purchased on Ebay.

    1. the suggested HF radio Yaesu FT-857D is $915.00 on Amazon, I don’t think that is cheap, did you have another in mind? I do need one that is affordable to me, so am interested in the best I can get for the least price, as I am a bit broke right now! Thanks!

      1. My suggestion would be a BaoFeng BF-F8HP which you should be able to get for under $80.

  2. Before this article I only considered our short range walkie talkie’s and our AM/FM/Shortwave/Weatherband radio. Now I will have to think about picking up a couple more LED flashlights to store. We can’t store the current ones as they always seem to be in use.

  3. Does a Faraday cage need to be solid metal or would metal screen work?
    How “tight” does the lid need to “seal”?
    Do I need to weld a metal cover or would an over lapping lip be enough?

    1. You might review some of the following articles – some of which touch upon some of this (also within the comments)

      Category: EMP

      With that said, metal window ‘screening’ is apparently sufficient for the frequencies involved – to obtain sufficient attenuation.

      In my opinion, a snug fitting conductive metal cover is plenty sufficient.

      1. Thanks for the past links. Went back and read some of them and read about doing the cell phone test so I decided to try it in a couple of my safes. I put my cell in the safe and called it from another phone. The safe effectively blocked the radio waves, the cell did not ring while in the safe. Makes me feel a little better knowing that my electronics and thermal scopes are protected.

      2. Watched a video weeks back , sorry I don’t have the link, where this fellow did testing on different enclosures for Faraday cages. He said the biggest improvement came when you sealed all seams with metal duct tape.

  4. This is a topic I am need of more info. I am currently storing 2 way radios, portable CB radios, a battery operated am/fm/weather/sw receiver, LED flashlights, a solar charge controller, a 2000/4000 watt power inverter, a 12/120 volt battery charger for NiMH AAA, AA, C, and D size batteries. I am using lined ammo cans stored inside a solid steel lined safe to store these items. My solar panels are too large to fit in the safe so they are kept in a large lined metal cabinet. The cabinet and safe are continuous steel with no gaps larger than maybe 1/32″ when closed. As I understand it, the energy waves created by an EMP or CME have a wavelength of 2-4″ so as long as there are no gaps this large or larger any metal container can serve as a faraday cage. As stated, both the safe and cabinet are lined with non conductive material to keep the items in them from touching the metal of the cage. Another question I have is on the solar panels themselves. I have read at some sources that if the panels ARE NOT hooked up to anything, ie charge controllers, inverters, or battery banks they would probably be safe if left unprotected during a CME or EMP. What about a lead acid battery bank? If disconnected, would they be ok during a CME or EMP?

  5. What would be the effect of an EMP on traditional batteries? Discharge? Complete failure? I may be wrong, but it seems to me that they would either overcharge and explode, or discharge depending on the circumstances (distance from the EMP event, sitting on or near conductive materials, etc). Might want to consider storing rechargeable batteries and a solar charger.

      1. However, if a battery is discharging its power thus creating an energy ciruit to a computer or to a vehicle that is running, the battery and every wire connected to it will be effected..

        only a battery that is not connected to anything will not be effected.

  6. I think the question is a lot more simple that “what to store?”. It is more ‘why?; or, should I store anything?”.

    Folks – an EMP produced by high-altitude nuclear detonation of the type that has been developed to maximize pulse-yield will penetrate most cages slapped together. In other words, 99.% of all electronics we are now burdened with thinking crucial to our day-to-day will be gone. I understand the question though as to what should be considered. Solar cells to begin with. They are all basically light-driven/opening/flow inducing diodes. For long-term power generation, they’d be the first choice. And without sufficient protection – they’ll be toast.

    For any radio – that is, 2-way comm – I counsel all to basically rethink any and all ideas of gabbing away on the air-waves. To do so most definitely will draw down upon you all the attention of those who mean you no good-will. From the government to the bad-guys. Listen – sure. But please, for your own sakes – shut up. But, given the choice between storing away a 2-way radio versus any of the following – I’d recommend these 7:

    1. calculators – you’ll have plenty of need for them to rebuild (solar cell powered)
    2. reception only radios – any and all frequencies. (hand-crank or solar again)
    3. portable drives – external hard drives, thumb drives, flash drives. But actually I would consider CD/DVD storage – see the next item….
    4. a CD/DVD player that is USB capable to hook to a computer – and of course….. ==> a small laptop with an optical drive.
    5. RDF/ADF units, radio band scanners, frequency counters
    6. medical equipment (EKG, transfusion pumps, medical scales…)
    7. diodes, transistors, common logic and usages integrated circuits – learn some basic electronics and ‘roll your own’ post-EMP

    As for lighting, or any other device that contains electronic circuits – you’ll find that in no time you’ll convert to old-school methods of lighting, heat, vehicle control, machine control, refrigeration…

    If the worst should happen – a nationwide EMP affected continent – life will not be the same in any way, shape or form. Best to get used to not worrying about what has been lost in terms of music, video, e-books, programs and all your supposed needs – i.e. cellphones, mobile devices, and all the rest of the b.s. you think you can’t live without. For if that is really true – you won’t live.

    1. I think electronic items not connected to the power grid (long wires = antennae) have a good shot at working, with the odds increasing as the distance from ground zero increases. Your i-toys won’t be much good even is they work, because cell towers and the internet require electricity. Even if your car runs, you will be quite limited by available fuel. Oil refineries will grind to a halt, and you didn’t REALLY think the strategic petroleum reserve was for YOU, did you?

      Electrical power will probably slowly come back on a local scale. The environmental schmucks in CA will have an especially tough time, since they refused to allow generating stations to be built and instead brought electricity in from long distances.

  7. Ok, here is one or two for you.

    As Heartless suggested, medical, question, how many people do YOU know that’s on a pace-maker? Your wife, husband? If we have a “real” CME or EMP those WILL stop, now a lot of people with PMs will make it for a little time without, but what if? would/could you cut open their chest and replace one?

    What about Hearing aids or other medical electronics that keeps someone alive?

    Just something more to think about


  8. @Lauren,
    You ask a very good question. Batteries such as A, C and D that are connected to anything electrical that makes a complete circuit will be fried. The battery casing makes a perfect Faraday cage except for when an electrical current can pass thru the battery(battery in a circuit). The electrolyte will boil in the battery due to the excessive current(wattage) and then the battery will just simply boil (or explode) over so to speak.

    Those same batteries not connected to anything will not be effected. Unconnected batteries can be setting on or near anything metal and still will not be effected by an EMP.

    Large amp-hour batteries such as in a solar battery bank will not be effected by an EMP because the time duration of the EMP is so short that the electrolyte of the battery will not have time to boil and the conductors are so large that they will not melt. There can be some electrical arcing inside a connected battery bank but that would be taken care of by surge protectors connected to your system.

    Also, the electrical field inside a Faraday cage is zero and therefore if your electronics touches the inside metal surface of the cage there will no problems for your equipment.

    I hope this clears up a lot of misconceptions. Be well all.

    1. In my opinion, the battery electrolyte will not have time to boil because an EMP is over in nanoseconds (with exception to a CME event from the Sun which is quite different – although my instinctive opinion regarding batteries in that situation is still the same).

      No disrespect intended – just my opinion.

    2. One has to consider the shielding effect of structures, wood shelves, etc. An EMP has never happened on a large scale, so a lot is conjecture.

  9. Would the cab of an auto serve as a faraday cage or would the glass and rubber door seals “leak” to much “charge”? I often have my laptop and other small electronics in my truck. If not, I am considering hardening a hard-sided brief case into a faraday cage and ditching the soft leather bag I now use for the gear. Are there any retail options out there for such a case? Thanks.


  10. @ken,
    No disrespect felt. Your instinct about electrolyte not boiling is correct except for those nuclear weapons designed to generate an EMP. Current flow caused by such weapons will last for nearly 20 seconds, the intent of such weapons is to also melt copper transformer cores and power transmission lines. These weapons are designed using slow fusion reactions. That is where my statement comes from.

  11. Learning a lot here. Question on EMP vs CME. I figured an EMP would be very brief and see that I was wrong. On CME, anyone with knowledge about duration?
    I kind of thought it would be luck of the draw meaning being on the daylight side and hit and being on the night time side and missed. But I wonder if it went on for a prolonged enough time and the cone was wide enough could the earth rotate through it, this exposing everybody?
    What I have stored is a few walkie-talkies, solar charge controller, blocking diodes for panels, LED flashlights, spare AA & AAA batteries, charger for same, multi-meter, net book, assorted flashdrives. Working on a flexible solar panel to go into a galvanized trash can but what is available has some rather large holes where the handles attach. The small stuff is wrapped in foam and then aluminum foil. Stored in a 20mm ammo can with the gasket removed, paint scraped of at the lip and gasketed with crushed aluminum foil. May I never need it!

    1. A CME (from the Sun) may last hours to days, whereas an EMP (man-made) will last nanoseconds to seconds… Hope that helps ;)

  12. Curious if a surge will effect a watch?

    I also keep a few of the inexpensive Wilkie talkie to hand out to neighbors as a method of keeping the neighborhood safe. This allows the few of us who are “like minded” to stay connected at specific intervals. Nothing major as the range on them is very limited at just a few blocks.

    Multiple small solar powers keep easy in a trash can and can be enough to maintain a battery for my back up CPAP machine.

  13. a fair number of people are familiar with the Carrington event
    but not many have heard of this

    Researcher points to Sun as likely source of eighth-century ‘Charlemagne event’


    “”What they concluded was that the energy emitted by the Sun would have had to have been, say, 1,000 times larger than the Carrington event—the greatest solar flare ever known,”

    fortunately for human kind
    events like this are incredibly rare
    should something like this occur today
    the results would be beyond devastating

  14. Any idea about fuel injectors? I have a spare computer module for my 89 Grand Prix that is wrapped in layers of aluminum foil in the trunk.

    1. @ Johnson
      Simply wrapping the computer in AL foil will not protect it as you might imagine. the Comp. must be insulated from the foil.

  15. I know this will sound weird but in addition to a lot of what has been listed I put in an electric hair clippers like a barber uses. Buzz cuts may one day be in demand. LOL. I also have a small dremmel tool for chainsaw sharpening and other tools.

    1. will it really matter if you protect those chargers/drills?

      won’t the grid be down for months/years?

  16. would a regular firearms safe ( such as stack-on brand ) work as a Faraday cage? The gap around the door is about an 1/8″

  17. Is there any truth to a majority of the vehicles (modern) on the roads today being obsolete after an event like this? And if so is there anyway to protect them? Such as a metal sided garage or something similar, at least if you are at home?

    This post strikes a nerve after finishing “One Second After”. Seems like the biggest strain on society in that book was the lack of communication and transportation of supplies (food, building materials, medicine).

    1. @ Northern Boy
      Interesting question, as far as “modern” vehicles, If the vehicle is inside a Faraday Cage, such as a Connex with a steel floor and seams sealed it should “survive”. Until the world relapses there would be no replacement parts to speak of, sure lots of “junk” cars around to salvage. One might also consider storing spare replacement parts for the electronics, but again, Fuel? Spare Parts? anything electronic will fry with a “major” EMP/CME. Suggestion, get a older Junker and fix it up, pre mid 70s and have spare coil and condenser. I’m having a BLAST restoring my 1961 Scout Pick-em-up-truck.

  18. Second these suggestions:

    laptop (and DVD library)
    battery chargers
    radios (AM/FM/SW, scanners, weather alert, and two-way)
    solar panels and inverters
    solar LED (flash)lights

    And a few I didn’t see mentioned in the article or comments:

    smoke/CO detectors
    motion detectors
    electronic scales (gram/milligram size)
    power supplies/voltage regulators/wall wart adapters
    portable generator
    Night vision scopes (on my list)

    We try to upgrade or replace electronics while our current items are still functional, then the old ones go in the cages as spares. The cages I build aren’t meant for the items to be easily accessible, I wrap individual items in multiple layers of aluminum attic radiant barrier with insulator material between and store those inside a larger cage so each item has at least two, and usually three, layers of shielding. It’s a trade-off, difficult to remove and re-store the items, but better shielded. Good to note too that shielding items against EMP damage doesn’t necessarily provide complete protection, it’s just attenuating the EM radiation the item receives. The better the shield(s), the more the attenuation. Multiple shields are cumulative in effect. The goal is to attenuate the strength of the pulse below the failure threshold of the individual components in the device being shielded. No shielding is perfect in the sense that it “stops” EMP, the strength of the pulse and the sensitivity of the items will vary.

  19. I have a large safe in the garage, I removed the door seal and replaced it with a copper weather strip. You can find them in any hardware store, old school.
    I replaced all the liner material with rubber sheet insulation. All the shelves are made from composite material. Like marine star board.
    In it I have a hoard of , radios, led lights, inverters, charge controllers, ect.
    Batteries are in a simple metal storage cabinet, set up the same way. But I keep them separated and keep this cabinet outside in a out building. In case of fire, and gases.
    In general, what I keep is solar parts, radios several of all. Electronic parts, my background is in electronics. Lights and batteries.
    I also have Generators, but I don’t worry to much about them.

  20. Haven’t seen these mentioned: light fixtures and light bulbs. If and EMP or CME were to happen and the lights are on, I think the surge would possibly fry the wiring and pop the light bulb. We will need lights!!!

    1. @ being watched
      You bring up an interesting note, and maybe some smarter than I would help out here. Will the surge from an EMP that can fry all of the transmission lines, transformers and power generators not also fry the wiring within the house?

    2. Finally someone is talking about light bulbs! Does any one know
      if one needs to provide EMP protection for stored light bulbs? I’d
      have to assume that incandescent bulbs would survive better than LED
      but what about florescent bulbs? No one wants to live in the dark.
      Oh I do assume that any bulb that is plugged in will fry. So I feel it is
      a good idea to have spares hence the question of do stored bulbs need EMP protection? And do all kinds need this protection

  21. Since this topic of a Possible EMP has come up, I MUST REMIND everyone that the FED has recently bought huge amounts of NBC respirator canisters for FULL FACE respirators and Potassium Iodide tablets!! They are preparing for nuclear attack!

    These supplies aren’t for the General Public!!!

    Wake UP!!!!

    1. @bob, Based on the reading I’ve done regarding the technicality of the surface effect of the Faraday cage, my conclusion is that technically, no it does not have to be grounded. However most people do.

  22. I am sometimes greatly amused by the lack of understanding of technical subjects I read on various web sites. Would one of the readers of this web site review Gausses Law and then post what they learn about Faraday bodies. This would really help other readers on this subject learn how to use a Faraday cage. But I will give you a heads up.

    Faraday cages do not attenuate the E.M. field at all. Grounding a
    Faraday cage does not improve or diminish the shielding capacity of the cage, nor does it have any other effect. The Faraday cage must be made of electrically conductive materials. Touching the inner surface of the cage will have no effect on the contents of the cage because the electric field inside the cage is zero. Also, as long as the hole size in a Faraday cage is much smaller than the incident radiation wave length, the cage will be effective at protecting the contents.

  23. the gooberment will be making efforts to disseminate information …. they’ll be using the emergency phone systems that are currently in place …. both an older cell phone and a simple landline phone should be included in the Faraday cage ….

    covering all possible bases is just good prepping ….

  24. Heartless asked the right question. Not what to store but why. Then plan accordingly. The Wife loves music so I have included that. I have range finders and night vision. Both of our vehicles have a small cage that fits a handheld ham radio. We have a plan on what to do if it happens.
    One of the best YouTube videos I have seen about testing cages for EMP is Dr. Bradley Cooper from Disasterprepper. About 11 minutes long. He does real testing.

    1. Dr. Bradley’s video is great, everyone should watch to see the dBs of attenuation he achieved in his various tests. The FutureScience site has some great information too.

  25. I have a pacemaker…is there anything at all that can be done to shield it from an EMP?
    Secondly, knowing there was an air burst or some other man made cause for an EMP, is there any measure of time and distance in which the EMP travels? In other words, for example, if I knew there was a detonation 500 miles away from me would I have time to react?

    Fortunately, my heart would not stop in my pacemaker stopped but I would be in the hurt locker in regards to a very low heart rate. Should I assume that if there is no way to shield myself that I can expect to get a new one implanted?

    By the way…great site / blog.

    1. There is a good book called Nuclear War Survival Skills by Cresson H. Kearny. I purchased it several years ago from Emergency Essentials…

      If the US is doing its job, there should be a warning given the the citizens as soon as a missile is launched. This would give you the greatest amount of time to react. After that and once detonated, light travels very fast and there should be a very bright light, brighter than you have ever seen before. A bigger problem is surviving the blast/heat wave that will follow if it is a ground explosion. This will travel faster than than sound travels… Remember seeing lightening and then hearing thunder? Not much time to react.. but after seeing the bright light, immediately seek shelter away from windows. If it is an EMP only weapon same thing, meaning little time to react after seeing the light. One can make a homemade Faraday cage out of aluminum foil. Perhaps if you made a vest out of plastic covered by aluminum foil and kept it in your pocket.. it might help and you might have time to put it on after receiving a civil warning. Not the best protection but could mitigate the effects enough to not damage your pacemaker. However, my guess is after seeing the bright light, there may not be enough time to do any needed shielding of a pacemaker. The metal in a car will provide some shielding against EMP as well which are OK for a high burst EMP weapon but not for a ground burst as windows could break and the car could be set on fire by the heat wave that follows. You could turn a closet into a Faraday cage and hope that it is reachable in case of a blast. Cover all the walls, ceiling, floor and doors with aluminum foil. These closets are not the best Faraday cage but it would help. This should be an interior closet with no windows. Anyway, I recommend the book as a good education. for more than just EMP. I hope this helps

      1. One other thought. Aluminum foil vests may give you some protection but are limited due to neck, arm and torso openings. Aluminum foil is the best EMP protection but mylar Faraday bags have shown to reduce EMP although less effectively than aluminum foil ones. Perhaps your best bet might be to carry a space blanket with you. These are made of mylar and would permit you to wrap yourself entirely in a mylar sheild so to speak. These space blankets are small when folded, light weight, cheap and could be more easily carried in your pocket. They are available on Amazon. This would give you more freedom than having to live in your aluminum foil lined closet. Hope this helps and Merry Christmas.

  26. First time on this site, will be back. I can heat my house, water, cook and so forth with wood. So the question is will an EMP kill my chain saw?

  27. @Country Bumpkin
    Most likely will not effect tha chainsaw unless it’s one of the new electronic ignition ones.

    1. Thanks for the feedback. We are very comfortable with growing our own food and old time skills. Some other things, not so much.

  28. Thank you for your replies…I will definitely get the book you suggested. I pray none of this will become reality but I fear we taht it make take more than prayers to undo what our current lack of leadership has accelerated by allowing Iran and others to go basically unhindered.

    May I suggest a book for all of you…”Epicenter” by Joel Rosenberg. Regardless of your religious beliefs, this book brings ancient history and the evolving circumstances of today into vey clear focus.

    1. Hi David, Thanks for the book suggestion and your kind words. I will purchase it. Although I am by no means a Biblical scholar I do believe we are in the “End Times” as mentioned in Mark 13 and other places. I grew up in the 50’s which was a time of hope and joy and promise. The times we live in now are a far cry from that… now it is all very scary. May God bless you and your family and protect you in wherever life takes you.

  29. Hi Pam, It sounds like we share some similar views and values.. I am not much of a Biblical scholar myself but I have been taking much more notice these days. Epicenter describes in great detail the book of Ezekiel and how it translates into modern day. The author is extremely credible as the book will illustrate. However, what makes it even more credible are the events that unfolding right before our eyes.

    I sincerely wish you and your family the same protections. May 2016 bring you all the very best in health, happiness and prosperity!

    1. Good Morning David, I ordered the book yesterday on Amazon. It should come soon. I read exerts on-line and figured that it might be a good idea to know what is coming to prep accordingly, so ordered it. Do you or anyone know of any live prepper fairs or meets? Or perhaps a website that lists them? I’ve done a lot but it would be helpful to meet like minded people.

  30. Hi Pam – sorry for the late reply. They only Prepper meet I am aware of was one held in Scottsdale, AZ about a year ago. I actually live in Scottsdale but unfortunately was out of town when they held it. I will try to get some information for you and see if this is something they will have again. I heard it was very well attended…I am amazed by how many of my neighbors are either currently active in being prepared or just becoming involved.

    Regarding the book…you will be shocked to learn where the safest place to be is. I won’t spoil it by telling you but make sure your passport is current!

    1. Hi again David,

      The book finally arrived and I have been devouring it. Due to my own research in the Biblical time line I have concluded that we are on the verge of the war of Gog and Magog. This book confirms everything I learned from my own research and added more. I do disagree with the Rapture theory. I think we will have to go “through” all this and I have heard some TV preachers refer to “the land of unwalled villages” as a reference to the USA which did not exist back then and may have been the best way to describe a then unknown place. But THANK YOU SO VERY MUCH FOR RECOMMENDING IT!!!! You have been a tremendous help. I will pass the book on to others!!!!!!!!!!!

    2. As a fairly new resident of the Phoenix area, I escaped from Mexifornia, I’d be interested in knowing if there is a prepper group that meets around town on a regular basis? I’m not totally prepared but prepared more than probably 95% of others but love learning more about this as I do believe that we’ll be needing to use these skills in the not too distant future.

  31. Good Morning David,

    How kind of you to do this research for me! I live just south of Sarasota FL in the winter and near Valley Forge PA in the summer. This means prepping in two places, each with its own unique requirements. But I have a bunch of frequent flier miles I need to use up so could make a meet there. I was in Scottsdale a number of years ago ..very nice town. (Vacation with now ex-husband.) You are fortunate. I also have some relatives that live in AZ. (And I do keep my passport current. :-) ) Most preppers are kind of in the every man for himself mode, and this has its place. But there is a time when collective/unified people need to stand against collective/unified evil. Perhaps for now this is just about helping each other prep. And I’m glad to hear that people are waking up and preparing. The more people who are prepared, the better. I run into toooo many people here in Florida who are clueless or have this weird attitude that if the SHTF, they dont want to live. Consequently, they are not preparing.. and ..I ..ah.. think they will get what they want. LOL Sorry, I guess I shouldnt laugh as this will be sad. But sometimes one needs a sense of humor or thinking about all this stuff will be too depressing. I’m glad you are level headed and taking the time to solve problems NOW while it is still possible. This prepping stuff takes time and serious thought.

    Happy New Year David, and many more! May you come through all this like Shadrach,Meshach and Abednego… untouched and without even the smell of smoke.

  32. I also store a Samlex 300 watt pure sine wave inverter (for charging my Dewalt and Craftsman tools and for operating sensitive electronic testing equipment if that equipment survives). I also store a spare solar charge controller, some Nitecore AC/DC battery chargers for my extensive flashlight collection, some 18650 batteries, and a hand held GPS.

    1. @ TX7

      Probably not. Most that prepare would suggest changing the lock to a mechanical one….


  33. I have a portable solar panel system that charges a rather heavy battery unit to provide portable power in the even of normal power disruption. I would like to know if that portable battery unit needs to be protected in the event of an EMP event?

      If the “Battery Unit” has any electronic components in it at all…. Yes it would been to be protected.

      1. Thanks for your quick reply.

        I am not very versed on electrical devices so I’ll ask a stupid question. This battery unit is kept plugged into the garage wall outlet all the time so that it will be fully charged whenever it is needed. I’m getting the impression from reading all these posts that since it is connected to the grid, it will likely be fried. So the best way to protect it is to disconnect it and then construct a cage for it. Yes?

        Also, the actual solar panels, they are packed in a cardboard shipping box only. Are they vulnerable too?

        1. @ Brian C…Yes you would want the battery unplugged. A stand alone battery (car, dry cells) should be fine. Batteries with prewired terminals should be caged as well as the other components to the solar system. Nest your cages, but make one just for batteries so you can get at them and recage them easily to keep them charged.

  34. I bought a Thunderbolt Solar 14W briefcase. I has a male and female car lighter like attachments. I have Ryobi cordless tools and a charger for the batteries P131 that instead of a wall plug has the male plug. So I believe I will ve able to recharge my Ryobi batteries and so use my tools and a Ryobi fan

  35. I saw a u-tube about sleeping in a faraday cage. I did not watch it, so I’m not sure if the pupose was to protect a pacemaker. I wonder if maybe a canopy bed, with fine metal mesh curtaining would work. Under the box spring would have to be a metal plate and all would need to be continuously touching. Any physics majors out there who could help with this?? A middle of the night emp attack is more likely considering time zones.

  36. I am protecting my hand-crank dynamo/battery/solar powered AM/FM/Police/Weather band receiver radios and my two 2-way FRS/GMRS walkie talkie and my two hand-held 2-way BaoFeng BF-8FHP amateur radios and accessories (SWR meter and connectors and USB chargable Li-ion power packs and USB-chargeable 14500 Li-ion 1.5V batteries) in Crossbreed ARK Resister EMP Protection bags. I have both 15.6″ whip antennas and the short OEM antennas for the BF-8FHP amateur radios, but I’m not planning on having any of the antennas connected to the radios inside an EMP Protection Bag. Do I need to protect the unattached radio antennas from the effects of EMPs or CMEs ?

    1. @Old Indiana Farmboy Bill,

      Quote, “Do I need to protect the unattached radio antennas from the effects of EMPs or CMEs ?”

      Answer: No. There are not electronics in those handheld radio antennas. Hope that helps.

  37. An overlooked question is how long does one need to keep items protected in Faraday cage? I have heard that there is some risk of delayed second EMP from high altitude nuclear blast by an american adversary to destroy the few electronics that have been removed from protection for use. I would also think that multiple smaller faraday cage containers of electronics would allow one to retrieve some items without risk of exposing all the protected electronics. I keep a few throw away solar calculators in insulated cookie tins and will open them first and if they continue to work then I would have more confidence that it is safe to open more protected supplies.

  38. Other things to consider putting in your EMP vault;

    Some inverters – sized to the load you want to drive – see Ken’s other articles on this.
    An AED – Automated External Defibrillator – they are finally getting within the realm of affordable.
    RF hacker with portapac H2 and Havoc software – software defined radio for TX and RX surveillance.
    Boat Radar set – You can see movement beyond visual range, most firearms are detectable.
    Night vision and flashlights – own the night.
    An old laptop with a copy of Navy Electronics Training Courses – 24 E-books
    Battery powered hair clippers – Scissors work but this is better.
    Ear Wax removal Endoscope with associated old iphone or android or laptop. – great for close up stitching or tooth extraction.
    All the associated plugs and adapters for charging flashlights, iphones, androids, flashlights, night vision, walkie talkies – to use with inverters.
    Old Nextel phones with encoded, PTT, walkie talkie, point to point communication, freq skipping capability with all the needed paraphernalia.
    Many voltmeters and calculators.
    Eneloop batteries and chargers – assuming you got some solar power left over.
    DC fans – on hot nights, this is all you might have.
    Drone – with FPV that can fly without GPS – with long range antennas – sure makes patrols safer.
    Voltage charge regulators (solid state) – for retrofitting cars or lawn mower alternator chargers with spare Zener diodes, and power transistors, and variable voltage regulators.
    Wireless remote control switches to be used for peaceful things like Halloween props.
    Lasers – The ones you can light stuff with – for peaceful things like Christmas displays.

    1. not so sure,
      that’s a very good list. can i recommend some ECM’s for the lawn and garden equipment.
      all of the gas in the world won’t help if your equipment doesn’t get fire to the plugs.
      small brigg’s motors and others all use the same electronic parts and their cheap, and not very hard to change out.
