I was actually looking for a useful solar alarm clock (and found one). But I also found this cool solar messenger bag. I wish it could also power my Powerbook because the batteries are always the “weak link” for road warriors.
Quantys: The solar panels generate 4 watts of power, enough to charge most devices smaller than a laptop computer. They are lightweight, waterproof and UV resistant, but are tough enough to withstand the rigors of everyday use.
The solar panels charge a 2200mAh Lithium Ion Battery Pack inside the front pouch. This stores any power generated by the panels, and delivers a smooth regulated flow of power to your devices, even when the sun is not shining.
