I was looking at those "power banks", which are I guess rechargeable batteries, maybe some kind of step-up transformer or induction coil. I might be better off just using my power tool batteries. I must have 4 or 5 20 volt Dewalt batteries and some kind of fixture that fits them that has a bright led light and various jacks to recharge a phone or whatever. I have a rechargeable tv and other battery operated lights, etc. They've really come a long way with all that shit - rechargeable batteries, low voltage lights, etc.
When there's a storm coming, we usually fill up some buckets with water too in case we lose power and can't use the well. Maybe I could get one of those water containers for drinking water and a kerosene heater and I'll be set. I love living in a small house. I'd live in a garden shed in a minute...cabin, hollow tree...whatever. There should be a drive in this nation to down-size every GD thing we own and do. Conspicuous consumption like a reptile doing some kind of mating display is vulgar and classless. It is the McMansion psyche. I prefer the tree-fort psyche....much more nimble and far less encumbering.
