Item for your consideration is a modified ammo can engineered to eliminate EMP.
Performance should be better than 64db attenuation of 30-1000 MHZ.
That's 20db or 100 times better than the best mil spec bags.
Placing your electronics inside a 30+ db attenuation mil spec bag and then placing that bag in this enclosure should exceed  MIL-STD-188-125-1 for High-Altitude Electromagnetic Pulse (HEMP) testing protocol.
At the current EMP strength of 150 kV/meter you might just need it.
Opening this can up after an EMP or CME event may give you the only working civilian radios/laptop/electronics in hundreds of dark miles. Even LED flashlights are at risk.  An absolute necessity for your Bitcoin thumbdrives.  Perfect for backup hard drives.  Big enough to fit usable sized solar cells and computers. https://youtu.be/rywSR2D79vY

We can provide additional items, including programmed handy talkies with lithium batteries.
They will work when you need them.
