I agree with the previous comment of Goal Zero being stupidly overpriced. It’s an easy target as they’re in most stores, but if you check out brands like AUKEY, they make the exact same thing for a fraction of the cost. Goal Zero’s Yeti is pretty rad, but there are defn cheaper options. However, having a mobile(ish) PV cell and battery pack is essential. Even in Armageddon I’d want my survival guide PDF I’ve got on my smartphone which wouldn’t work without electricity!
I wrote a blog on this a couple years ago for the Dallas preppers the place to go is Honeyville. Do the math and figure out protein, carbs, vegetables, and fruit per serving and order case lots. To pull together that much it’ll run you about $3000 and then you’ll have what you need. I parcel mine into tubs two tubs will feed a family of four a balanced diet of 1800 cal per day for a month.

After 9/11, my dad filled a duffel bag with some energy bars, a couple gallons of water, some penicillin, and a map. Amid scaremongering headlines about imminent anthrax and “dirty bomb” attacks in the city, he wanted to have some supplies on hand in case we needed to get out of Brooklyn fast. Were he to assemble such a bag today, he’d likely stumble on a number of companies promising a more wholesale brand of disaster preparedness: a box full of shelf-stable freeze-dried meals, to be revived from their dessicated state with the addition of boiled water.
