Faraday Bag for Laptops & Tablets & Car Keys - 3 Pack Faraday Cage, Faraday Key Fob Protector, Fireproof & Waterproof RFID Bag, Car Key Signal Blocker(Black)

The media could not be loaded. The size is perfect. The design is amazing. I’m really pleased. And it’s very durable and easy to use. Has a little carabiner for easy carrying.

The way to test these is to place your phone inside and seal it up. Then try to call your phone from an outside phone. If the call doesn't go through then you know they work. I tried this with all 3 and all 3 were successful. Would highly recommend due to the value, quality and different size options.

These are generously sized. The larger envelope for laptops accepts my MacBook with room to spare. Slide my cell phone in, too. Gave my wife the tablet sized one for her iPad. With your computer or phone inside no signals are getting in. When you remove them they have to reconnect to the internet and download mail and messages so should keep out unwanted electric impulses as well hopefully. Guess I won't really know if they work until there is an EMP so hopefully only purchased insurance and never need them or find out if they work under extreme conditions.

I initially tested these by starting a screen recording on an iPhone 15 Pro Max and placing it in each bag for about a minute. The device (with a thin case) wasn't far from being too tall for the smallest of the 3 bags, but it did fit and allow the bag to fold properly. In the smallest (phone) and largest (laptop) sized bags, the iPhone lost Wi-Fi and cellular signal and showed the satellite icon. In the medium (tablet) sized bag, it lost Wi-Fi and cellular signal and just said No Service (no satellite icon).I tested the small and medium bags again by putting an AirTag in them. After double folding and velcroing the small bag, I could not use the Find Nearby or Play Sound functions. For the medium bag, the Play Sound function worked, but when I folded and velcroed the bag again, it stopped working.

Wifi, Bluetooth, and DATA services blocked when applied properly. Confirmed by using secondary devices to ping the "trapped" device.

Super good value and nice sizes for most peoples needs. You have to be careful to seal the velcro completely and it's not the easiest to open with the biggst bag. But you can do it. I tested it and it did the job.

Work as advertised.. Can't confirm GPS signal blocking, but DOES block cell signal effectively...

I ordered the  3 pack faraday bags after being impressed by the one ordered by a friend, but was shocked when it arrived.  They are NOT the same!  My package had a drastically reduced size cell phone faraday bag from the other, and well below the specified size in text and photos in the Hodufy listing on Amazon.  The overall length of the bag I received was over 1/2 inch shorter while folded, and more than an inch shorter when open.  My phone will not fit in what they sent me, but it would in the originally seen one.  Also, in order to cut the size, they installed the velcro strips too close together and you can't even fold the bag flat when empty, let alone with your valuables inside.  It would surely tear and separate in little time.  Thinking it was a one off quality issue, I've ordered a replacement set, and the new set arrived to find same shortened length and issues closing, plus they were under specified size on width.  I've attached photos of the 3 hodufy cell phone bags I've seen as well as another brand purchased on amazon showing it is true to advertised measurements, as was the 1st of 3 Hodufy bags.  The other brand of faraday bags also has far cleaner stitching than Hodufy.  I'm afraid if I order any more from Hodufy, the cell bag won't even fit my keyfob.  Going back!

işe yaramaz

Nice item

Ser bra ut

Je suis plus que bluffé de l'efficacité de ce produit.Aucune onde ne traverse les pochettes.Je l'ai essayé sur de la radio FM, GSM, 3G, 4G, 5G, Wifi et Bluetooth.

Auch wenn ich die Größe vor dem Kauf schon wusste, wirken diese Taschen so großzügig. Das ist das doppelte ist was ich erwartet hatte. Die Verarbeitung ist wirklich sehr hochwertig und deswegen wurde wahrscheinlich auch die Eigenmarke von außen zusätzlich drauf gesteckt. Ich habe ein Smartphone In eine der Taschen gelegt und zu gefaltet und es ist kein durchkommen. Genau was ich wollte. Besser als ich erwartete!
