Response: Thank you I, had seen this panel. I am not sure that it is
something solid enough to carry around on the backpack in areas where
you may have to go through underbrush.

Response: I have seen the site. This guy has a lot more engineering
knowledge than I can muster. It would have to be a complete project
after next trip. For now it is too late. It would be OK for batteries,
not for solar. However, I wonder why he does not use a dynamo for
recharge. Downhill, he would collect energy at no cost, and on a
cruise a dynamo is not too hard to run, although with the load he has
on his bike...

Response: Actually I make it a point to carry those batteries with me
and 10 pounds should be excessive I believe.. What I really look for
is for a DC alternative to the AC wall socket. Besides a GPS, I have
two Canon cameras, with different battery types of course. So a
battery solution for one is not good for the other. An AC contraption
that would be able to recharge batteries of any type would be the
preferable solution. And then on boondocks treks where different
people with different electronic gear congregates it would fit the
trek organizer to have such a power-gear on the mule for participants
to reload at night, rather than everyone carrying an individual
solution, or carrying multiple batteries for multiple electronic
gears.
Separately, I have tried to see if one could generate enough power
through a small physical gear (bicycle or stepper) and a dynamo.
Unless I am mistaken the power equation shows that there is far more
energy in these little batteries that one would be ready to deliver
after a day's trek.
