Mission Darkness Dry Shield Revelation Faraday Bag
The Dry Shield Revelation is designed for EMP and CME protection with a military-grade Faraday enclosure. Its large capacity is suitable for most compact portable generators, solar panels, computer towers, and other large devices. The bag is MIL-STD-188-125 certified, with a focus on preserving device integrity during electromagnetic events. Interior dimensions offer substantial space for tall or bulky equipment, and the bag folds down for compact storage when empty.
Mission Darkness Dry Shield Rapture Faraday Bag
The Dry Shield Rapture provides an extremely large, 1,060-liter capacity suitable for portable gas or solar generators, oversized electronics, and emergency gear. It features three layers of high-shielding TitanRF fabric on all interior sides with durable seam construction to maintain shielding during EMP or CME events. The bag blocks RF signals across WiFi, Bluetooth, GPS, RFID, and other radio frequencies, delivering robust EMI and EMR protection.
Mission Darkness Eclipse Faraday Bag
The Eclipse Faraday Bag is geared toward solar panels and large electronics, offering military-grade EMP, CME, and RF shielding. Made in the USA, it provides certified shielding per MIL-STD 188-125 and IEEE 299-2006 with reports available on request. It blocks a wide range of RF signals (including up to 40GHz for some configurations) and is suitable for technicians and preppers seeking robust, domestic manufacturing and testing authenticity.
Xtreme Sight Line G CUBE 100 Faraday Bag
The G CUBE 100 model from Xtreme Sight Line is designed to shield portable power stations and generators from EMP and GMD threats. Made in the USA (Las Vegas, NV), it features interior dimensions suitable for medium to large equipment in a 20″ tall by 20″ wide by 15″ deep configuration. The product emphasizes durable construction and effective RF and EM shielding for high-value gear.
Xtreme Sight Line G CUBE 50 Faraday Bag
This G CUBE 50 offers a compact yet capable shield for small to medium generators and electronics. With a diamond-form Faraday interior and a 15″ interior footprint per side, it provides multiple layers of shielding against RF signals, GPS transmissions, and EMP/GMD threats while maintaining portability for field use and quick deployment.
Buying Guide
Key considerations when selecting an EMP/EMI shield for generators and large electronics include shielding effectiveness, interior capacity, durability, and certification.
- Shielding and certifications: Look for MIL-STD-188-125 or MIL-STD equivalent testing, and independent test reports when available. This ensures devices maintain functionality during EMP/CME events and helps verify shielding claims.
- Interior capacity and shape: Generators, solar panels, and large electronics require bags with generous interior dimensions. Consider whether the bag’s form (rectangular, diamond, or roll-top) fits your gear and storage space.
- Material and construction: Military-grade fabrics and multi-layer shielding provide stronger protection. Check seam construction, zippers, and handles for long-term durability in field conditions.
- Portability and storage: Bags that fold down or compress when not in use save space. Padded straps and rugged exterior help with carrying and weather resistance in varied environments.
- RF signal blocking scope: Some bags block broader bands (WiFi, Bluetooth, GPS, RFID, 5G). Consider your risk model and whether comprehensive RF shielding is necessary for your use-case.
- Made in USA and warranties: If domestic manufacturing and readily available test reports matter, prioritize brands with USA production and transparent documentation.
Selecting between larger capacity bags and more compact variants depends on your gear inventory and expected deployment scenarios. If you routinely transport sizable generators or multiple solar panels, a 1,000+ liter capacity bag may offer the most practical solution. For field teams prioritizing quick access and lighter gear, a 15″ to 20″ interior bag with robust shielding can be sufficient while reducing weight and bulk.
