Faraday Generator Dry Bag by Faraday Defense

The Faraday Generator Dry Bag is purpose-built to shield mid-size portable generators from EMP, Bluetooth, Wi-Fi, cell, GPS, and RFID signals. It utilizes a clip and roll seal for enhanced blocking that ensures minimal signal penetration. Constructed from three layers of CYBER fabric, this dry bag offers robust protection coupled with waterproofing and strong MOLLE webbing for practical carrying. Its supported base structure adds durable support, ideal for field and emergency settings.
Mission Darkness Dry Shield Rapture Faraday Bag

This Faraday bag stands out with an extra-large 1,060-liter capacity, able to accommodate large portable gas or solar generators along with additional electronics or tools. It contains three layers of high-shielding TitanRF Faraday fabric applied internally with dual paired seams to maintain the integrity of electronic devices during EMP or CME (coronal mass ejection) events. The bag blocks WiFi, Bluetooth, cell signals, GPS, RFID, and radio frequencies with an average attenuation of 70dB, providing comprehensive electromagnetic shielding.
EMP Shield Whole Home Generator Protection

Designed primarily for residential use, the EMP Shield offers military-certified EMP protection to safeguard your entire home’s electrical systems, including the generator. Manufactured entirely in the USA by a veteran-owned company, it meets Department of Homeland Security standards. This device actively blocks harmful pulses from lightning strikes, solar flares, and EMPs, ensuring continuous power and safety during grid disturbances.
Mission Darkness Dry Shield Revelation EMP Armor

The Dry Shield Revelation bag offers MIL-STD-188-125 certification, verifying its high standard of EMP and CME protection trusted by law enforcement and preppers. It is built to fit a wide range of equipment, including compact gas and solar generators, radios, medical electronics, and smart home devices. With an extra-large usable interior (30″L x 24″W x 22″H), it can accommodate taller and bulkier items. Its foldable design allows easy transport and storage.
NEWARR Faraday Bag for Generators and Large Electronics

This military-grade Faraday bag is designed for protecting personal privacy and devices against hacking or electromagnetic interference. It blocks an extensive range of signals including WiFi, Bluetooth, cell signals up to 5G, GPS, and radio frequencies up to 40GHz. With an extra-large capacity (30″L x 24″W x 20″H), it easily stores compact generators, power stations, and large electronics. The bag folds compactly for storage, making it convenient to carry and deploy where needed.
Buying Guide for EMP Covers and Faraday Bags for Generators
Choosing the right EMP cover or Faraday bag depends on several important factors tailored to your generator’s size, usage, and protection needs.
Size and Capacity
Measure your generator’s dimensions and ensure the cover or bag has sufficient internal space. Extra-large bags accommodate oversized generators, accessories, and additional electronics. Keep in mind that some bags allow flexible fitting by not using the full width or length.
Shielding Material and Certification
Look for covers made with multilayered high-shielding fabrics such as copper-nickel-polyester blends or specialized materials like TitanRF. Certifications such as MIL-STD-188-125 indicate military-grade EMP protection adherence, assuring proven effectiveness.
Signal Blocking Range
The best covers block a wide frequency range — including WiFi, Bluetooth, cellular (including 5G), GPS, RFID, and radio signals — to protect against all common electromagnetic threats. Check attenuation values like 70dB or higher for superior shielding.
Additional Functionalities
Waterproofing, durability, and design features such as clip-and-roll seals, MOLLE webbing, and reinforced bases contribute to practical use during field deployment or storage. Some covers feature foldability for easy transport.
Compatibility with Generator Operation
Some solutions protect generators even while running via specialized metal tarps or enclosure tents. Consider your operational needs — if you require continuous power during storms or EMP incidents, find a cover designed for use during operation.
Made In / Manufacturing Quality
Domestic manufacturing (such as American-made products) and veteran-owned companies may offer additional assurance of quality and compliance with safety standards.
