Keep Generators and Extra Large Electronics Shielded

The Mission Darkness™ Revelation EMP Shield is an extremely large faraday bag designed specifically to protect generators, large electronics, and survival gear from the damaging effects of an electromagnetic pulse (EMP) or coronal mass ejection (CME). The bag has been lab tested and certified "compliant" for MIL-STD-188-125, High-Altitude Electromagnetic Protection for Ground Based C41 Facilities. The results ensure that the product surpasses military shielding requirements to handle natural or man-made EMPs. In the case of an EMP or CME, everything from electrical infrastructure on a national level to personal electronics could be destroyed, which is why it’s imperative to shield survival electronics. The high-shielding properties of the Revelation EMP Shield direct damaging electromagnetic fields away from highly sensitive electrical components, thus protecting their working structure.

The extremely large size and volume of the Revelation EMP Shield allows it to accommodate most compact portable electric (solar) or gas powered generators, including the Goal Zero Yeti series, the Patriot Power 1500, and the Honda EU2000, plus their accompanying accessories such as power cords and solar panels. The bag is built with a removable polypropylene plastic base plate secured in a bottom zipper compartment to provide ample support for oversized items. Padded handles with load-bearing webbing completely wraps around the sides and bottom to support the weight of heavy objects during transport. The front side of the bag includes a deep unshielded zipper compartment and a large transparent pocket to keep accessories accessible while not compromising the shielding of the electronic items inside the main compartment.

The bag is built with a durable and water-resistant ballistic nylon outer material to ensure that devices and faraday fabric stay dry and protected. The interior includes three layers of high-shielding TitanRF™ Faraday Fabric on all sides with dual paired seam construction. Once the generator or electronics are properly enclosed inside the bag, they become isolated from outside wireless signals. Damaging effects from an EMP or related occurrence cannot penetrate the bag to destroy the electrical components inside. The bag will block WiFi (2.4 & 5GHz), Bluetooth, cell signals including 5G networks, GPS, RFID, NFC, and radio signals from low MHz to 40GHz. The complete signal cut-off also allows you to go off-grid and keep electronic devices untrackable. This is the ultimate safety bag for protecting large survival electronics from a natural or man-made disaster occurrence such as an EMP or CME.

MIL-STD-188-125 Compliant for High-Altitude Electromagnetic Protection

The Revelation EMP Shield underwent rigorous lab testing to certify that the product meets military standards MIL-STD-188-125. This compliance measure not only ensures that the product shields against high-altitude electromagnetic pulses (HEMPs) and related occurrences, such as coronal mass ejections (CMEs), electrostatic discharges (ESDs), and solar flares, but also provides concrete proof to the shielding ability and effectiveness of the bag. The image below shows the shielding effectiveness results.

Just the right size

When I ordered the MOS bag I was concerned it would not be able to contain my solar generator and two batteries. After taking out the removable bottom, the bag was flexible enough to hold everything inside. I was able to get the top flaps to Velcro together as designed. I have a bit more comfort knowing the generator and battery are protected.

Nice bag!

As soon as it arrived I put my solar generator and equipment in the bag along with my cell phone. I had my wife call my phone and it did not ring. It didn't even register as a missed call. That was awesome! The bag is huge and has lots of room for my generator and other electronic devices.
