The bummer is that, depending where you live, there is a good chance that even if you preserved your electronics, you wouldn't have any mains current to run them for a long, long time. I would be more worried about rushing to Walmart and stocking up on canned goods and bottled water before anyone else figured out what was about to happen.

Very correct.I think in case of a mass electricity failure across the world. Without water supply, fuel and other energy resources to transport food, medicine and other essential supplies.

More than protecting your electronic gear, the struggle is likely to be for food and other emergency resources.

I am sure there will mass riots and mafia scale entities controlling resources critical to survival. Besides 2/3rd will be dead in quick time anyway. Nobody has every survived without water or food.
