10 Essential Items to Keep in a Faraday Cage for EMP Protection

Imag­ine a sud­den burst of ener­gy capa­ble of ren­der­ing most mod­ern tech­nol­o­gy useless—in an instant, the world as we know it could change due to an elec­tro­mag­net­ic pulse, or EMP. This sce­nario is not just the premise of a sci­ence fic­tion nov­el; it’s a real con­cern that could pro­found­ly impact our reliance on elec­tron­ic devices. As some­one who pre­pares for the unknown and under­stands the impor­tance of readi­ness, I’ve delved into the con­cept of a Fara­day cage—a cru­cial line of defense against such unpre­dictable events. A Fara­day cage, named after the inge­nious sci­en­tist Michael Fara­day, serves as a pro­tec­tive shield, encap­su­lat­ing and pre­serv­ing vital elec­tron­ics from the destruc­tive capa­bil­i­ties of EMPs.

In our con­tin­u­ous quest for EMP pro­tec­tion and pre­pared­ness, we’ve rec­og­nized that not all devices are replace­able in a post-EMP sce­nario. That’s why, in this com­pre­hen­sive arti­cle, I’ll share with you the top 10 essen­tial items every prep­per should have tucked away in their Fara­day cage. Through my research, I have learned the intri­ca­cies of how a Fara­day cage works and the vary­ing lev­els of EMP shield­ing it can pro­vide, ensur­ing that even if an EMP were to occur, unplugged elec­tron­ics could stand a chance of sur­vival. These insights, cou­pled with prac­ti­cal advice on items like emer­gency radios and water purifi­ca­tion devices, will guide you in turn­ing your Fara­day cage into an invalu­able sur­vival arse­nal. Join me as we delve into the essen­tial prep­per prac­tices that pre­pare us for the unex­pect­ed and teach us how to mit­i­gate the poten­tial dev­as­ta­tion of an EMP strike.

Portable Solar Chargers

In the event of an EMP, hav­ing a reli­able source of pow­er is crit­i­cal, and that’s where portable solar charg­ers come into play. These devices are invalu­able for keep­ing essen­tial elec­tron­ics oper­a­tional when the grid is down. Here’s a break­down of some of the top options to con­sid­er for your Fara­day cage EMP pro­tec­tion set­up:

• Pock­et-Sized for Con­ve­nience: The Patri­ot Pow­er Cell and Ren­ogy Portable E.Flex are excel­lent exam­ples of pock­et-sized mod­els that are per­fect for indi­vid­ual devices. They’re easy to car­ry, mak­ing them ide­al for per­son­al emer­gency kits.
• Mid-Range Pan­els for Effi­cien­cy: For a bal­ance between porta­bil­i­ty and pow­er, the Big­Blue Fold­able 28W is a sol­id choice. It’s designed to unfold and soak up the sun, pro­vid­ing a reli­able charge to your gad­gets. Its porta­bil­i­ty makes it com­pat­i­ble with a bugout bag, ensur­ing you’re ready to move at a momen­t’s notice.
• High-Capac­i­ty Gen­er­a­tors for Greater Needs: When you need to pow­er mul­ti­ple devices or larg­er items, the Jack­ery Portable Pow­er Sta­tion Explor­er 500 and Goal Zero Yeti 3000x stand out. These are not just solar charg­ers but com­plete pow­er sta­tions capa­ble of keep­ing crit­i­cal devices like med­ical equip­ment run­ning.

When con­sid­er­ing the best over­all portable solar charg­er, the Big­Blue Solar­Powa looks like a stand­out for its effi­cient bal­ance between solar charg­ing and porta­bil­i­ty. I have some­thing sim­i­lar in 200 watts vs. 120 watts.  For those seek­ing the best val­ue, the X‑Dragon 28W offers reli­able and fast charg­ing at an afford­able price point. I have an old­er 15-watt ver­sion of this… If you need a high-out­put mod­el, the Flex­So­lar 40W looks capa­ble of charg­ing not just USB devices but also portable pow­er sta­tions, thanks to its DC out­put. I do not have one of these but am look­ing into a Goal Zero portable charg­er that I may upgrade to, and may upgrade my solar pan­el… 

For those of you prep­pers who pri­or­i­tize porta­bil­i­ty above all else, the Goal Zero Nomad 5 is a sol­id pick just based on the fact it is Goal Zero. Their gear is sol­id. This solar charg­er is small enough for back­pack­ing, incred­i­bly thin, and durable enough to with­stand the rig­ors of out­door use. On the oth­er hand, the Jack­ery SolarSaga 100 is a larg­er pan­el that offers user-friend­li­ness and light­weight con­struc­tion, per­form­ing admirably in var­i­ous weath­er con­di­tions.

It’s impor­tant to note that while solar pan­els are fan­tas­tic for charg­ing small elec­tron­ics, they are not rec­om­mend­ed for direct lap­top charg­ing due to poten­tial volt­age fluc­tu­a­tions that could cause dam­age. Instead, use a com­bi­na­tion of a bat­tery and a solar pan­el to max­i­mize pow­er generation—utilize the bat­tery in the evenings and recharge it on the pan­el dur­ing the day.

Remem­ber, when select­ing a portable solar charg­er for your Fara­day cage, con­sid­er fac­tors such as direct and indi­rect solar charg­ing speed, porta­bil­i­ty, func­tion­al­i­ty, and over­all solar charg­ing effi­cien­cy. This will ensure that your EMP shield­ing is as robust as pos­si­ble and that your elec­tron­ics remain pro­tect­ed and pow­ered, even when unplugged.

Emergency Radio

In the wake of an EMP, stay­ing informed is vital, and that’s where the inclu­sion of an emer­gency radio in your Fara­day cage EMP pro­tec­tion set­up becomes indis­pens­able. These radios are not your aver­age tuners; they are equipped with fea­tures specif­i­cal­ly designed for dis­as­ter sce­nar­ios:

• Mul­ti-Band Func­tion­al­i­ty: The best emer­gency radios offer AM/FM radio capa­bil­i­ties, along with access to weath­er band chan­nels. This ensures you can receive crit­i­cal updates and alerts no mat­ter the con­di­tions out­side. For exam­ple, the Kaito KA500 Voy­ager is a pop­u­lar mod­el among prep­pers, known for its reli­a­bil­i­ty and com­pre­hen­sive band cov­er­age.
• NOAA Weath­er Alerts: A cru­cial fea­ture of these radios is the abil­i­ty to tune into NOAA weath­er updates, which broad­cast over fre­quen­cies like 162.400. These alerts pro­vide life­sav­ing infor­ma­tion dur­ing severe weath­er events and oth­er emer­gen­cies.
• Inte­grat­ed Flash­lights: Many emer­gency radios also come with built-in flash­lights, adding an extra lay­er of util­i­ty. This dual-pur­pose func­tion can be a game-chang­er in pow­er out­age sit­u­a­tions, allow­ing you to nav­i­gate safe­ly in the dark while stay­ing updat­ed.

When con­sid­er­ing how does a Fara­day cage work and its role in EMP shield­ing, it’s evi­dent that an emer­gency radio is a must-have. Not only does it serve as a life­line to the out­side world, but it also address­es the con­cern of ‘will an EMP destroy elec­tron­ics that are unplugged’ by ensur­ing you have a device that remains func­tion­al post-EMP. Remem­ber, the goal of a Fara­day cage is to pro­tect devices from elec­tro­mag­net­ic inter­fer­ence, and an emer­gency radio is designed to work in envi­ron­ments where oth­er elec­tron­ics may fail.

As you stock your Fara­day cage, pri­or­i­tize an emer­gency radio that is robust, reli­able, and capa­ble of receiv­ing a wide range of sig­nals. This is a cor­ner­stone of EMP pro­tec­tion and a tes­ta­ment to the impor­tance of under­stand­ing what is a Fara­day cage and how it can safe­guard your com­mu­ni­ca­tion tools. Keep in mind that while no device is entire­ly invul­ner­a­ble, the right prepa­ra­tions can sig­nif­i­cant­ly increase your chances of main­tain­ing access to vital infor­ma­tion when you need it most.

Flashlights and Batteries

In the face of an EMP, the right light­ing can make all the dif­fer­ence in safe­ty and maneu­ver­abil­i­ty. While our Fara­day cage EMP pro­tec­tion is top-notch, we must con­sid­er light­ing options that go beyond the ordi­nary. Here are some essen­tials:

• Diverse Light­ing Options: Tra­di­tion­al can­dles and flash­lights might not suf­fice in an EMP sur­vival sce­nario. I rec­om­mend incor­po­rat­ing a vari­ety of light­ing sources, such as:
  • Solar light­ing solu­tions which har­ness the sun’s ener­gy, pro­vid­ing a sus­tain­able light source.
  • Olive oil lamps, an ancient tech­nique that burns clean and is sur­pris­ing­ly effi­cient.
  • Crank flash­lights which require no bat­ter­ies and can be pow­ered up with a bit of elbow grease. These options ensure that you have light when you need it, with­out rely­ing sole­ly on bat­tery-oper­at­ed devices.
• High-Lumen Flash­lights: A robust flash­light is non-nego­tiable in our EMP pre­pared­ness kit. Here’s what to look for:
  • A min­i­mum bright­ness of 200 lumens, though I pre­fer around 500 lumens for opti­mal vis­i­bil­i­ty.
  • Adjustable beam set­tings to tai­lor the light to your spe­cif­ic needs, whether you’re nav­i­gat­ing a dark path or need to focus on a task at hand.
  • Mul­ti­ple modes, includ­ing SOS for emer­gen­cies, and recharge­able bat­ter­ies to ensure longevi­ty and adapt­abil­i­ty.
• The Tac­Swan EMPEROR Flash­light: This is a stand­out addi­tion to any Fara­day cage EMP kit. Not only is it the first of its kind to resist EMPs, but it also offers flex­i­bil­i­ty in pow­er sources, accept­ing either a CR123 or an 18650 bat­tery. It’s a wor­thy invest­ment for those who take their EMP pro­tec­tion seri­ous­ly. I hap­pen to like Nitecore, these days… 
• Redun­dan­cy is Key: I always stress the impor­tance of hav­ing back­ups for your back­ups. This means mul­ti­ple flash­lights for dif­fer­ent locations—your house, car, and bug-out bags. Brands like GearLight and Ever­bright are among the top rec­om­men­da­tions for 2023, offer­ing reli­a­bil­i­ty when it mat­ters most.
• Long-Last­ing Can­dle Options: For those times when you need a soft­er glow or a back­up to your back­up, long-burn­ing emer­gency can­dles are a must. The 115-Hour Plus Emer­gency Can­dles by Emer­gency Essen­tials are a fan­tas­tic choice, pro­vid­ing a clean and odor­less burn for near­ly five days straight.

In our quest to under­stand how does a Fara­day cage works and its role in EMP shield­ing, it’s clear that diver­si­fi­ca­tion in light­ing is a crit­i­cal aspect of our pre­pared­ness strat­e­gy. By equip­ping our­selves with a vari­ety of light­ing options, we’re ensur­ing that should an EMP strike, we won’t be left in the dark. Remem­ber, the goal is to be pre­pared for all sce­nar­ios, and with these light­ing solu­tions, we’re one step clos­er to achiev­ing that.

Hard Drive or USB Drives

In the realm of EMP pro­tec­tion, safe­guard­ing dig­i­tal data is para­mount. Elec­tro­mag­net­ic Puls­es (EMPs) can wreak hav­oc on elec­tron­ics, includ­ing the hard dri­ves and USB dri­ves that house our most impor­tant infor­ma­tion. Here are some prac­ti­cal mea­sures I’ve tak­en to ensure my dig­i­tal data remains intact in the event of an EMP:

• SLNT Bags: To shield my elec­tron­ic stor­age devices, I use SLNT Fara­day Bags. These are not your aver­age stor­age bags; they are designed with a heavy-duty, five-lay­er con­struc­tion that includes two lay­ers of met­al and a mois­ture bar­ri­er. This supe­ri­or shield­ing per­for­mance is cru­cial for devices like hard dri­ves and USB dri­ves, which are sus­cep­ti­ble to both EMPs and elec­tro­sta­t­ic dis­charge (ESD).
• DIY Fara­day Cages: I’ve also explored the DIY route for EMP shield­ing by cre­at­ing a Fara­day cage. One method involves using a stur­dy shoe box lined with alu­minum foil and sealed with tape. Alter­na­tive­ly, a gal­va­nized met­al buck­et with a snug-fit­ting lid, lined with card­board, and sealed with alu­minum tape can serve as an effec­tive home­made Fara­day cage. To ensure its effec­tive­ness, I con­duct­ed a sim­ple test using a cell phone to ver­i­fy that sig­nals were indeed blocked when the phone was placed inside the cage.
• Opti­cal Stor­age as an EMP-Resis­tant Back­up: For long-term data preser­va­tion, I’ve turned to opti­cal stor­age solu­tions. Reg­u­lar CDs and DVDs are sur­pris­ing­ly resilient against EMPs and can last from 5 to 200 years, depend­ing on the type. How­ev­er, for the most crit­i­cal data, I’ve opt­ed for M‑DISCs, which boast a lifes­pan of up to 1000 years. While their longevi­ty isn’t guar­an­teed, they are engi­neered to be more durable than stan­dard opti­cal discs.

In addi­tion to these elec­tron­ic mea­sures, I also advo­cate for a low-tech back­up method: print­ing out cru­cial data. This approach cir­cum­vents dig­i­tal preser­va­tion risks alto­geth­er, ensur­ing that even if all elec­tron­ic mea­sures fail, the infor­ma­tion sur­vives.

By incor­po­rat­ing these strate­gies into my EMP pro­tec­tion plan, I’ve bol­stered the resilience of my dig­i­tal data against the threat of an EMP. It’s essen­tial to under­stand how does a Fara­day cage work and to rec­og­nize that while no method is fool­proof, com­bin­ing these tech­niques increas­es the odds of keep­ing our dig­i­tal life intact post-EMP.

Two-Way Radios

In our Fara­day cage EMP pro­tec­tion toolk­it, com­mu­ni­ca­tion is key, and this is where two-way radios come into play. They’re essen­tial for coor­di­nat­ing with local Emer­gency Pre­pared­ness teams and stay­ing con­nect­ed with your group. Here’s what you need to know about includ­ing two-way radios in your EMP readi­ness plan:

• Motoro­la T470 Walkie Talkies: These are a sol­id choice for per­son­al use, thanks to their robust design and exten­sive chan­nel com­bi­na­tions. With 121 pri­va­cy codes and FRS chan­nel fre­quen­cies, they offer a total of 2,662 com­bi­na­tions, ensur­ing pri­vate con­ver­sa­tions even in crowd­ed fre­quen­cy bands. Their rugged build makes them suit­able for any sit­u­a­tion, whether it’s a nat­ur­al dis­as­ter or an EMP event. Find out more about their capa­bil­i­ties and how they can enhance your EMP pro­tec­tion strat­e­gy here.
• Under­stand­ing Radio Pow­er Lev­els: The range of two-way radios can be influ­enced by the pow­er they oper­ate at. For instance, Fam­i­ly Radio Ser­vice (FRS) radios typ­i­cal­ly oper­ate at low­er pow­er lev­els of 0.5 watt or 2 watts, while Gen­er­al Mobile Radio Ser­vice (GMRS) devices can trans­mit at pow­er lev­els rang­ing from 1 to 5 watts. This dif­fer­ence in pow­er lev­els can sig­nif­i­cant­ly impact the trans­mis­sion range, which is a cru­cial fac­tor to con­sid­er for your Fara­day cage EMP set­up source.
• The EMP SAFE Com­mu­ni­ca­tions Kit: This kit is the ulti­mate invest­ment in EMP shield­ing, offer­ing a com­pre­hen­sive set of tools for main­tain­ing com­mu­ni­ca­tion post-EMP. It includes:
  • An EMP-resis­tant stor­age con­tain­er to pro­tect your gear.
  • A dual band two-way hand­held radio (BaoFeng UV-5RA) with adjustable pow­er out­put (1–5 watts) for ver­sa­tile com­mu­ni­ca­tion reach.
  • Essen­tial acces­sories like charg­ing cra­dles, exter­nal micro­phones, ear­pieces, and a mag­net­ic mount anten­na to enhance usabil­i­ty.
  • A com­pact solar pan­el to keep your radio pow­ered with­out rely­ing on the grid.
  • A pre-pro­grammed list of essen­tial fre­quen­cies includ­ing FRS, GMRS, MURS, and Weath­er chan­nels, ensur­ing you’re ready to tune in to impor­tant updates.
• The BaoFeng UV-5RA radio is par­tic­u­lar­ly note­wor­thy for its abil­i­ty to send and receive on both the 2 MHz and 440 MHz bands, giv­ing you a wider range of com­mu­ni­ca­tion options. How­ev­er, it’s impor­tant to note that trans­mit­ting on HAM radio fre­quen­cies requires a basic HAM Technician’s license and some addi­tion­al pro­gram­ming to ensure legal­i­ty and opti­mal per­for­mance. The kit linked at the time of this writ­ing is priced at $56 for two with stronger bat­ter­ies, and weighs only a cou­ple pounds com­bine.

By incor­po­rat­ing these two-way radio solu­tions into your Fara­day cage EMP, you’re tak­ing a sig­nif­i­cant step towards ensur­ing that, should an EMP strike, you won’t be cut off from the rest of the world. It’s all about being pre­pared and under­stand­ing how does a Fara­day cage work to pro­tect your com­mu­ni­ca­tion devices, which could be the life­line in a post-EMP sce­nario.

Non-Electronic Survival Gear

In addi­tion to the elec­tron­ic devices safe­guard­ed with­in a Fara­day cage, it’s equal­ly impor­tant to have non-elec­tron­ic sur­vival gear on hand for long-term emer­gen­cies. These items are indis­pens­able for self-suf­fi­cien­cy and safe­ty when mod­ern con­ve­niences are no longer avail­able.

• Pro­tec­tion and Defense:
  • Firearms and ammu­ni­tion can pro­vide secu­ri­ty and hunt­ing capa­bil­i­ties. Stor­ing them in bio­met­ric gun safes ensures quick yet secure access.
  • For non-lethal options, bear spray is a pow­er­ful deter­rent against wildlife and poten­tial threats.
• Water Essen­tials:
  • Store at least one gal­lon of water per per­son per day. Enhance your water stor­age with tools like LifeS­traws or water purifi­ca­tion tablets for safe drink­ing.
  • Keep elec­trolyte hydra­tion pow­der on hand to main­tain prop­er hydra­tion lev­els dur­ing stren­u­ous activ­i­ties or in hot cli­mates.
• Food Stor­age:
  • Aim for a min­i­mum of three months’ worth of food sup­plies. Include a vari­ety of non-per­ish­ables such as canned goods, dried legumes, grains, and high-ener­gy snacks. Reg­u­lar­ly check and rotate your stock to ensure fresh­ness.

When con­sid­er­ing EMP pro­tec­tion, remem­ber that not all sur­vival gear requires pow­er. A robust plan includes items that func­tion with­out elec­tric­i­ty:

• Basic Sur­vival Gear:
  • Gen­er­a­tors: Con­sid­er gas, propane, or solar-pow­ered options for ener­gy inde­pen­dence.
  • Fire Starters and Cook­ing Tools: Include match­es, lighters, and a portable stove.
  • Shel­ter and Warmth: Stock up on emer­gency blan­kets and have a fire blan­ket with DuPont X‑1 on hand for fire-relat­ed emer­gen­cies.
• Health and Hygiene:
  • First Aid: Assem­ble a com­pre­hen­sive first aid kit with ban­dages, anti­sep­tics, and essen­tial med­ica­tions.
  • Hygiene Prod­ucts: Stock­pile soap, tooth­paste, fem­i­nine hygiene prod­ucts, and toi­let paper to main­tain clean­li­ness and pre­vent dis­ease.
• Sur­vival Tools:
  • A good, full-tang knife is a ver­sa­tile tool for a mul­ti­tude of tasks, from food prepa­ra­tion to self-defense.
  • Com­mu­ni­ca­tion Plan: Estab­lish a meet-up loca­tion and main­tain a list of items and meth­ods for con­tact­ing like-mind­ed indi­vid­u­als.

By inte­grat­ing these non-elec­tron­ic items into your EMP shield­ing strat­e­gy, you’ll be well-equipped to han­dle a vari­ety of sur­vival sit­u­a­tions. Whether it’s for defense, sus­te­nance, or main­tain­ing hygiene, these essen­tials will ensure you’re pre­pared for the after­math of an EMP event where the ques­tion of ‘will an EMP destroy elec­tron­ics that are unplugged’ becomes a real­i­ty. Under­stand­ing how a Fara­day cage works and com­ple­ment­ing it with non-elec­tron­ic gear is a com­pre­hen­sive approach to EMP pro­tec­tion.

Water Purification Devices

By under­stand­ing and imple­ment­ing these mea­sures, we stand ready to face poten­tial chal­lenges with con­fi­dence, fos­ter­ing a sense of secu­ri­ty in an increas­ing­ly unpre­dictable world.

FAQs

An EMP event can be a nat­ur­al or man-made occur­rence that dis­rupts elec­tri­cal sys­tems. To help you bet­ter under­stand how to pro­tect your elec­tron­ics, here are some fre­quent­ly asked ques­tions about Fara­day cages and EMP pro­tec­tion:

• What is an EMP and how can it affect my elec­tron­ics?
  • An EMP, or Elec­tro­mag­net­ic Pulse, is a burst of elec­tro­mag­net­ic radi­a­tion that can cause sig­nif­i­cant dam­age to elec­tron­ic devices, poten­tial­ly lead­ing to data loss or com­plete fail­ure. This can hap­pen dur­ing solar flares or as a result of a man-made attack. The threat of EMPs makes it cru­cial to pro­tect sen­si­tive elec­tron­ics, as they can stop func­tion­ing tEM­Porar­i­ly or per­ma­nent­ly depend­ing on the EMP’s pow­er and the device’s con­nec­tion to pow­er lines[https://www.thebugoutbagguide.com/Faraday-cages-EMP/][https://ham.stackexchange.com/questions/14900/how-does-a-Faraday-cage-block-an-EMP].
• How does a Fara­day cage work to pro­tect my devices from an EMP?
  • A Fara­day cage oper­ates by redis­trib­ut­ing elec­tro­mag­net­ic radi­a­tion over its out­er sur­face, effec­tive­ly neu­tral­iz­ing the charge and pre­vent­ing it from affect­ing the con­tents inside. It’s made from a con­duc­tive mate­r­i­al, typ­i­cal­ly alu­minum, and must be con­struct­ed with­out any gaps to be effec­tive. Sim­ple elec­tron­ics with­out sol­id-state elec­tron­ic con­trols are most like­ly to sur­vive an EMP if pro­tect­ed with­in a Fara­day cage[https://www.lbagroup.com/resources/Faraday-cage-faqs].
• Can I use alu­minum foil as a DIY Fara­day cage?
  • Yes, alu­minum kitchen foil can be used to atten­u­ate an EMP sig­nal, reduc­ing its strength to that of a strong FM radio sta­tion. How­ev­er, com­plete­ly enclos­ing all devices may not be prac­ti­cal due to the need for cables or open­ings. To ful­ly pro­tect against EMPs, espe­cial­ly from radiofre­quen­cy weapons, thick­er met­al sheets are required. The effec­tive­ness of a DIY Fara­day cage also depends on fac­tors such as the fre­quen­cy, inten­si­ty, and wave­form of the EMP, as well as the thick­ness and con­struc­tion of the cage[https://mosequipment.com/blogs/blog/Faraday-bags-and-EMP-protection-protecting-your-electronics-in-an-age-of-growing-electromagnetic-threats].

Remem­ber, while Fara­day cages offer a first line of defense against EMPs, there may be lit­tle to no warn­ing before a strike. The best prepa­ra­tion includes not only EMP shield­ing but also ensur­ing you and your fam­i­ly are ready for the after­math, with a stock­pile of sup­plies for poten­tial long-term sur­vival with­out pow­er.
