As the portable ‘everythings’ of the world get more powerful so do the battery demands. But wait, there is salvation. Enter the PSP Solar Charger. Although this won’t resolve your cell phone battery issues (like mine on the S710), it will keep your thumbs happy and mind busy as long as the Sun, or some light, is available.
The charger has a built in Lithium battery and charges in 4 hours. The solar charger also supports the Nintendo DS and runs for $35 – not bad considering an extra PSP battery alone runs from $20-40.
