Faraday Bag for Phone & Key Fob | Full Signal Blocking

Protect your phone from EMF radiation and unwanted tracking with our faraday bags. These signal-blocking pouches use Faraday cage technology—a conductive enclosure that redirects electromagnetic fields around your device, completely blocking all wireless signals.

What's in this collection: Phone pouches in multiple sizes, laptop sleeves for larger devices, and travel bags for comprehensive protection. Each bag is constructed with military-grade shielding materials tested to block up to 99%+ of signals.

How faraday bags work: Named after scientist Michael Faraday, these bags use conductive fabric that forms a continuous shield around your device. When sealed properly, no signal can enter or exit—not WiFi, cellular, Bluetooth, GPS, or RFID. You can verify effectiveness yourself by placing your phone inside and trying to call it.

Choosing the right size: Check your device dimensions against our sizing guide. Phone pouches fit devices up to 6.7" screens. Laptop sleeves accommodate 13" to 15" screens. For multiple devices, our larger bags provide room with the same complete signal blocking.

Lab-tested protection: Every bag undergoes independent testing with published dB reduction ratings. Our standard phone pouches achieve 80+ dB attenuation—that's over 99.99% signal reduction. Test results are available on each product page so you can verify the protection level.

Browse faraday bags to find the right fit for your device and protection needs.

Unlike shielded cases that protect you while allowing phone function, full faraday bags block all signals completely. Your phone can't receive calls, texts, or data while inside. This complete isolation provides guaranteed privacy and prevents tracking.

Full faraday bags are essential for security-conscious users, but they're also useful for anyone wanting true disconnection. Put your phone in the bag during meetings, meals, or sleep to ensure zero signals reach or leave your device. When you're ready to reconnect, simply remove it from the bag.

Frequently Asked Questions

Do faraday bags actually block all phone and key fob signals?
Yes, faraday bags work by creating a conductive enclosure that blocks all wireless signals. Our bags are lab-tested to 80+ dB attenuation—that's 99.99% signal blocking. You can verify effectiveness yourself: place your phone inside, seal the bag, and try calling it. If it goes straight to voicemail, the bag is working.
Can my phone be tracked when it's inside a faraday bag?
No. A properly sealed faraday bag blocks GPS, cellular, WiFi, and Bluetooth—all the signals used for tracking. Your phone cannot send or receive any data while inside, making tracking impossible. This also means you won't receive calls or messages until you remove the phone.
What are the disadvantages of using a faraday bag?
The main trade-off is accessibility: you can't use your phone while it's protected. You'll miss calls and messages until you remove it. For key fobs, you'll need to take the fob out to unlock your car. Some users keep a secondary pouch to quickly swap between protected and accessible modes.
Do faraday pouches lose their effectiveness over time?
Quality faraday pouches maintain effectiveness for years with proper care. The shielding materials don't degrade from normal use. However, physical damage—tears, holes, or worn seams—can create gaps that leak signals. Inspect your pouch periodically and test it with your phone. If it stops blocking calls, it's time to replace.
Does TSA allow faraday bags through airport security?
Yes, faraday bags are TSA-compliant. They appear as normal bags on X-ray scanners—the shielding materials don't trigger security alerts. You may be asked to open the bag for visual inspection like any other carry-on item. Many frequent travelers use faraday bags specifically to protect devices and prevent wireless skimming at airports.
