Currently interested in portable chargers. Some of these uses solar power and were reviewed in RACV's Royal Auto magazine, August 2009 issue, p. 8, FreePlay FreeCharge | Hymini |Powermonkey eXplorer. Many tech magazines have pinned Solio as the most powerful 1 on the market. While I'm currently own 1 EnergizerToGo that is not solar powered and planning to own a more eco friendlier device. Um. If only I can win one. lol. You can see them on my flickr album click here.
Solio classic white solar portable charger.
Hymini - a wind/solar powered device that wicked when you put it on your bike's handle bar.
