Hi all - we're off to do Kilimanjaro and a safari in a few weeks. I have a Solio Rocsta solar charger - but something appears to be wrong with it. I looked at the Solio website and it's like the device never existed. I wasn't all that happy with it anyway because it could only boost the charge on my devices. When the Blackberry was dead there was no hope to get it to charge. Nowadays, I have way more electronic gear I'd like to charge using solar with USB adapters: a new camera that now has a proprietary battery, Nook, and my phone. Any suggestions?
