Personally, I prefer having an ereader that runs on 4ea AA Batteries. So I can charge
them out of the reader, using any power source I wish. This means that I can have a
charged set ready and waiting whenever the set in my ereader runs out. Solar charging
is very practical here in Texas, and in fact this level of solar/PV use is actually a
practical endeavor, as opposed to trying to power a modern household.
I can get AA solar charging kits that can easily provide enough charged batteries to run
a number of devices I can use in the field. I can even get a solar charger that has a
USB charging port, as well as being able to charge my batteries.
Luck;
Ken
