This unit is also based on the PowerFilm cells, and produces more power than the 
unit below (4.62 watts vs. 1.44 watts). But it weighs more (6.08 oz. vs.
3.4 oz.) and if you use a 12V cigarette lighter type system to run a 5 volt
USB device, you are throwing away 58% of the generated power as heat (in 
down-converting to 5 volts) which is a waste of energy and weight.

Adding that extra weight and size just to throw it away doesn't make sense to 
me. Thus I prefer the quad AA model.
