To put it blunt, the battery life on all cellular/smartphones suck. Japanese manufacturer’s Links International introduce two versions of their solar-powered iCharger: the DX and the Lite. The standard DX and smaller Lite chargers work as a three-way amenity; standing in as a solar, AC, and USB charger.
The iCharger juices up a plethora of devices, bearing connectors for portable gaming consoles such as the Nintendo DS and Sony PSP, along with the obvious iPhone/iPod, eMobile and other Japanese cell phones. The expected charging time for both devices lie around 13-15 hours (solar) and about 2-3 hours via cable connections.
