[pct-l] charging your ipod

[Robert Kristoferitsch]

More and more often I hear that hikers use the iphone for journaling, gps, digital maps, e-mails....
so they use it a lot... every day for hours?

how do they keep the iphone charged? a little solar device for the big ipod?

I don't have one yet but my brother does.  he has to charge his iphone nearly every 1,5 days be using it in a normal way... not for business!

any suggestions?
thanks robert
