BLACKOUTFaraday Cage EMP Bags Premium Ultra Thick 5pc Prepping Kit Laptops Tablets Smartphones Hard Drives

these blackout bags really work, Tested my phone with the small one and it completely lost reception. It works really well for me. They do get a little beat up if you keep using them, but so far the bag itself has not been ripped and its last for now. the quality of the bag is not bad either so i do not expect it to tare any time soon. These are good quality bags for protection and off the grid needs.

Product looks great! Nice assortment of sizes, fit all I needed. Will update after the big dreaded "EMP", and if it protected my electronic data......

Great EMP solution! The bags are made with thick material, closes easily and can fit a few relatively small devices. I haven't tested it but based on it's solid construction I have faith that it will work. The bags are a form of insurance: hopefully I won't need them but I'm glad that I have them just in case.

Good bags, thick and seal well. I tried a cell phone and it didn't have signal. a GOS and a ham radio in them and didn't get a signal.

I store batteries and two old hard drives in these. I don't know if they work because I am sitting here waiting for an EMP event. If and when that happens, I won't get back to you, because my computer will no longer be working, but I hope my flashlights will!

I have not been near an EMP so I can't attest to how good the EMP BLACKOUT Bags work in a real-world EMP. If and when I am near an EMP, I will follow up with an additional review. Until then 3 stars.

It passes the cell phone rest so I'm completely satisfied with the product. The bags are solid in quality and construction. Good size to fit just about whatever you need.

These bags are a good size and can also be used for other equipment, but care needs to be taken because the substantially thick, silky metallic fabric can get thin tears with any squarish item, and a flat, rounded corner item is best of course. I put all kinds of electronic items in the bags to see what they would hold, and if a moderate amount of items, batteries, portable flashlight-radio etc. could be put in them. I would say, yes, but be very careful, and put these bags on a tray or flat surface of some kind. Plugs, and an antenna must be carefully packed so as not to pierce the package. Ironically, these bags are rather fragile. Putting these items in a nylon or net bag and then putting them in the larger bag might be good insurance.
