The original solBAT was a neat idea - a backup battery that charged through an integrated solar panel and can be plugged in to any USB device. But it was $US100. The latest sequel, on the other hand, is just $US30.
Mounting to a window thanks to some suction cups, or hooking to pretty much anything with a clip, the 1500mAh solBAT II puts out 5V, which is enough throughput to charge your iPhone as fast as you can from the wall.
So how was this price drop possible? The original solBAT included perks like voice-enabled caller ID - something most of us are probably willing to live without. For $US30 (available now), I'm willing to give the solBAT II a shot. [Scosche]
