If you are prepping then be sure to keep spare electronics in a Faraday Box. Even bubble wrapped then foil wrapped and tap serves as that purpose. And you can make your own boxes, google has instructions.
Good advice which is why I bought a batch of different sized Faraday ‘bags’ from Amazon some time back. I even keep an old laptop tucked away and some old cell phones. One never knows what they might be worth after an EMP event.
