these things are also available on-line at http://www.jaycar.com.au 
in two differnt sizes.  you can compare the specs and prices there 
with plain solar panels in various sizes.

AFAIK the only difference between these "car chargers" and plain 
cells is the cable with the cigarette lighter plug, there's no charge 
control circuit added.  not that i've checked, they just look that 
way to me.

IMHO they are not such good value against plain panels of a similar 
rated capacity.

anyone out there thinking of buying solar cells might want to know 
that the "word on the street" is that amorphous silicon cells (sold 
as Canon Uni-solar) are the best price-performance compared to the 
other two main types:  poly-crystalline and mono-crystalline.  they 
work better in cloudy or partly-shaded conditions, and thus give you 
more charging hours per day.

there's been a couple of threads on this line - if you like i could 
dig them out and mail them to you.  mail me off list.
