"The Voltaic backpack is powerful enough to charge most portable electronics (other than laptops) including: cell phones, cameras, two way radios, GPS's, PDA's, even iPods"
That says it all, no? I was on vacation in Yosemite National Park last week and I wish I had this cool backpack to keep my 2 way radios charged.
Price: $229 [voltaic systems]
