On the off chance that manufacturers and PR folks read this blog...
For years now I have been looking for a way to charge my laptop in case I lose power for an extended period of time (such as after a hurricane). It doesn't have to power it directly, although that would be nice; simply trickle-charging it will do. Having a battery supply that would allow me to run a box fan in order to stay cool is also a very good thing.
The problem isn't finding such a product. The problem, as always, is that I have a severely limited budget and cannot afford the several hundred dollars these systems cost. The (very) few systems that are in my price range are, shall we say, of questionable durability and I really don't want to just throw that kind of money away.
I've been told that I can assemble a rudimentary system fairly easily. Such discussions usually involve formulae of volts, amps, and watts thrown about willy-nilly. I don't do well with any math more involved than simple arithmetic and, frankly, I don't trust myself not to screw something up. What little I know about electricity has instilled in me a healthy respect for its power, and I know full-well that it is something one does not simply screw around with.
So, in the event that someone out there has an alternative energy method of charging a laptop and powering a box fan, please contact me. I am poor, but I have a good readership of techno-geeks, gunnies, preppers, and other folks who are likely to be interested in this sort of thing (my review of survival stoves was very popular and sold not a few of the ones I liked), and I would be willing to trade my pretty, pretty words in exchange for testing your fine product.
