BLACKOUT Faraday Cage EMP Bags Premium Ultra Thick 12pc Prepping Kit Laptops Tablets Smartphones Hard Drives

These bags look and feel very well made and i feel they should provide substantial protection. I personally feel any bag like this should be put inside another larger faraday cage. The seller is fantastic to work with. I had an issue with my order that was not the sellers fault and the response and follow-up i received was outstanding. I strongly recommend these bags.

Was surprised at how well this works. Placed my cell phone in a sock to prevent it from touching the bag wall. Sealed the bag and then attempted to call it. No ring and the phone was complaining of no signal when I removed it from the bag.If you place the phone directly in the bag, the phone will get signal from the bag wall. Direct contact thwarts the faraday effect.

I liked that there was quite a collection of sizes, they seem sturdy, and the ziploc closures seem to work just fine. That's about all I can say, since we have not experienced an EMP yet. I'm just trusting that they will protect the electronics that I have chosen to put into them.

I tested these prior to leaving for DEFCON in Las Vegas. Simple test, WiFi calling turned on so this is dealing with the WiFi access points in our house. Yes they are Prosumer grade WAPs [Ubiquity]. It took nesting he phone in 3 bags before it would not receive a phone call. Now let's think this through for just a second. If it takes 3 of these to just stop a strong WiFi signal, how do you think they will hold up to an EMP from a nuclear weapon. So ya worthless, just worthless. Very upset that I wasted money on this product. I could have just bought a roll of aluminum foil at Costco and probably have had better results. Yes seriously!

Won't really know how well this works until an EMP event happens (God Forbid), but it arrived on-time, all pieces were included as advertised, and they have a comforting thickness to the bags.The largest ones are large enough for my laptop, and the smaller ones would be good for a cell phone. I have an emergency radio and emergency old phone with scanner apps as well as a charger for both in 3 total small bags.

If it was to stop a emp it won't in my opinion. I can turn a radio on set it in the bag and it still plays. If it can do that then it's won't protect against emp.

I have not used them yet, but plan to in the very near future. They look extremely strong. I feel confident they will do the job.

I was a bit skeptical but I wanted to give this company a shot. here's a test with wifi router before putting the bag in front of emf sensor. again if a SHTF day came then I won't know if they would hold up but they definitely work for everyday use.
