Links over in Japan has come up with a solar powered battery charger that can charge any device via a USB port, including the PSP and DS. The Solar-Fine 1350 doesn’t look like the smallest charger out there, but it looks portable enough to get the job done. A day out to the park or a forced family picnic no longer means having to listen boring “remember when?” drivel. Obviously you’ll need to live in a sunny area to use this effectively. Obviously.
