Tech Protect – The Top Faraday EMP Bags

Tech Protect Faraday EMP bags are the only ones that have been tested to military standards.

Our bags use the most up to date metalizing technology. This provides an excellent moisture barrier. Not only will your electronics be protected against EMP attacks, but any items properly sealed in the bag are going to stay dry as well.

Our bags feature multiple layer construction to EMPs, EMI, RFI, ESD, and tribocharging. The bags seal completely to form a Ziplock type seal, making them easy to access. They’re also much more compact than Faraday cages and other EMP protection containers.

What Qualities Do Good Faraday EMP Bags Have?

Not every Faraday bag you can buy offers the same level of protection. In fact, quality among manufacturers varies quite widely.

Basic Faraday bags available today are designed to block electromagnetic interference (EMI) and not much else. Some of them don’t even do this very well, as we’ll see later in this article!

When you’re looking for Faraday bags, you need to look at how effective the shielding is, in terms of attenuation or dB. Anything beyond 40 dB is a good level of protection. Be cautious of any sellers who aren’t able to provide technical specifications for their product.

There’s so much of misinformation on the internet about what actually qualifies as a Faraday bag and what they can protect against.

Basic Faraday bags online are marketed as a way to block radio wave transmissions and electric currents to prevent identity theft, hacking, and to block tracking. For an average person just going through the airport and looking to protect their credit cards and other data from being stolen, such products might be sufficient.

For law enforcement and federal agencies, these entry level Faraday products won’t be sufficient. Especially when protecting valuable evidence and information like laptops and cell phone from being remotely erased, hacked, or tampered with.

For preppers interested in protecting themselves against an electromagnetic pulse caused by a nuclear bomb or solar flare, you want the top Faraday emp bags on the market today. Making sure that your electronics like solar panels and radio communications will still be operational after the power grid goes down could be a matter of life and death. So it only makes sense that you’d invest in the most reliable and quality EMP protection that you can find.

How To Use Faraday EMP Bags

Improper use of an EMP bag can render them ineffective against electromagnetic pulses. Luckily using them is quite simple. After you’re done reading this part of the article, you will know how to effectively store electronics in EMP bags yourself.


At Tech Protect, we always advise to use nesting for extra levels of EMP protection.

Nesting is placing one Faraday bag inside of another. This will double your protection against an EMP. This is why our bags are the sizes they are. Two small bags will fit inside one medium bag. Two medium bags will fit inside of one large bag. And so on all the way up through the sizes.

When an EMP happens, gamma radiation excites electronics in the Earth’s magnetic field. As this energy hits pieces of metal like antennas, power lines, or telephone wires, it gets conducted into them. Any electronics connected to these metal objects will receive a strong pulse of electricity that can fry them.

An EMP from either a solar flare or nuclear bomb detonation will produce about 50 dB worth of gamma radiation. Quality Faraday bags can filter out about 40+ decibels. This will reduce the strength of the EMP to only around <10 decibels when it hits your electronics, which typically isn’t enough to harm them.

However, to be completely safe it’s still a good idea to nest one Faraday bag inside of another. Two bags will be able to filter 80 dB of gamma radiation, which is more than any powerful EMP can produce, meaning 0 decibels will reach your electronics.

Another reason to nest your Faraday bags is because some countries have developed Super EMP bombs. This technology produces enough gamma radiation to break through even standard EMP protection. Nesting should theoretically be enough to protect against such a device, depending on its strength. It’s estimated that a Super EMP can produce about 80 decibels of gamma radiation, so two Faraday bags nested together would completely cancel it out.

Make Sure To Close the Bags

Your Faraday bags can’t have any kind of cracks or openings. If provided with any way to get in, EMP energy will always find its way to a piece of metal and start to conduct to it.

A Faraday bag has to be completely sealed for it to be able to redirect the energy pulse away from the contents inside of it. If your bag is open even in a little bit, EMP energy will find the opening and destroy whatever sensitive electronics you’ve stored inside.

You also can’t have anything plugged in while it’s in a bag for the same reason. Anything connected to the power grid will conduct energy from an EMP and be destroyed even if it’s fully inside a Faraday bag.

If you do need to take something battery powered out of a bag to keep it charged, do so for as short a time as possible to minimize your vulnerability. Set a schedule where you only unzip your bag to charge any battery-powered electronics inside it once per week for a few hours. Don’t forget to seal your bag back up when you’re done. And if you receive any kind of emergency broadcasts about potential nuclear conflict or solar flares while charging, it’s best to stop and get your electronics back inside your Faraday bags as soon as possible.

Tech Protect Faraday bags are easily sealed just like Ziploc bags. To make the seal permanent, you can also use an iron to melt the edge of the bag shut.

Be Ready For A Second EMP Strike

After an EMP strikes, you might open your bag and see all that your electronics are still in working condition and think you’re in the clear.

But wait there’s more! There’s a good chance that if the US is struck by one nuclear EMP, a second EMP will follow up a couple weeks later to finish off any remaining electronics or rebuilding that has been done in the meantime. This would happen most likely within 7 to 14 days after the first event.

Don’t fall into a sense of security because you survived the initial EMP blast. It’s still worth only using your electronics for brief periods when needed and then storing them inside your Faraday bags otherwise.

Faraday EMP Bags on Amazon

Nearly all the products marketed on Amazon as Faraday EMP bags won’t provide you with any kind of real protection in case of an EMP attack.

These aren’t really Faraday bags at all, and it’s a shame that Amazon continues to allow companies to use this misleading kind of marketing.

Most of these bags are made of leather or fabric with only a thin layer of mylar or similar material inside the pouch in an attempt to protect from electromagnetic radiation.

They seal shut with just velcro, leaving huge gaps at the top of the bag for electromagnetic pulses to enter and destroy your equipment.

We bought a few of these products to test them out, and they weren’t even effective at blocking signals from key fobs or credit cards, which is what they were mainly designed for.

These bags are also really small! Most will only fit a couple of key fobs or credit cards, so you’re out of luck if you want to protect even a tablet or anything larger.

Most of these are cheaply manufactured in China and use deceptive language about what they can really do!

Related Questions

Q: Why can’t I just use mylar or anti-static bags?

A: These products aren’t designed or capable of protecting against the destructive force of an EMP. They are only able to block very weak signals and amounts of electricity. We tested food grade mylar bags, and they weren’t even able to stop wifi or cell phone signals, which only operate at about 11 watts or a 2.4 GHz frequency.

Q: Can I do anything else to add extra protection to my electronics?

A: Before putting your electronics into a Faraday bag, you might want to wrap them in plastic to act like an insulator. Then wrap them in two layers of aluminum foil before placing them into Faraday bags. This will offer a little bit of additional protection.
