Just when I was going to show the bag with the radio and batteries in it, my phone stopped recording. The medium bag fit all the batteries in it with the NOAA crank radio. The 3 set of bags was $38.86 on Amazon and you can put also a tablet and fob/keys (RFID), car signal blocker, fire proof, water proof.
I like those bags! I got one for my phone then wondered how much notice I would have of an EMP. Probably none. So I put it in the bag every night, figuring the bad guys would want to set it off when no one was awake to be warned. Another thought--I also got protection for a couple of small solar chargers (and my old phone that is full of books and other good stuff) and charging cords, both C size and mini. I may not need batteries with solar chargers since there is sun practically all day, all year here. Good idea about the key fob, I will add my spare one to my stash!
