Right you are; entirely my fault, and corrected now.
Sorry, and thanks.
I have a rechargeable battery bank, a bank that uses 4xAA drycells, and a few 12v-powered usb sources. The drycell one stays in my globebox with some AAs, as it can be "recharged" on short notice with a trip to any store. The rechargeable one is in my center console, to be grabbed if I need to recharge my phone. That one also has a simple little bright white LED light on it and makes a nice impromptu flashlight. (IMHO every battery bank should have this feature, look for it if you are shopping around, it also has a charge level indicator and can be switched off without unplugging the device, but alas only one USB port)
On the floor is one 7 port power station, that can supply two 2amp and 5 1amp ports off the truck's 12v power, good for rapid-charging high-demand things like tablets or other banks. Its daily duty is to power my GPS, a pair of USB speakers on my dash, and keep my iphone charged. Most of the "high power usb chargers" are garbage and a waste of money. This one's actually designed for it and speced to do the job. (http://www.startech.com/Cards-Adapters/USB-3.0/Hubs/7-Port-Dedicated-USB-Charging-Station~ST7CU35122)
I know several people that have those cheap usb-personal-fans and use a bank to run them, they keep them in their purse and pull them out when they're somewhere hot and want to cool off.
I'm also ordering two DC-DC converters shortly, one that steps down and one that steps up. It occurs to me that I can use the step-up to generate 12v etc from a 5v USB source, which may come in handy.
It's not an "idea", it is genetics that you are intolerant of. And the bigotry is based on intolerance against specific genetics. And boo on you if you don't like it, that's just the way it is. Analysis and reason is fruitless when confronted with tribalism and instinct. Just not worth my time. Besides, I am more easily humored by watching you play dumb.
The unintentional hilarity of YOUR shiny, new, fascist tribalism is its nihilistic inability to perpetuate hooey, but not the tribe itself.
I denounce myself afresh as the bad guy for upholding the notion that Form Follows Function; Flees Foolishness; Flames Falsehood.
