A 12V solar panel can easily produce 18V without a big load - and that can be too much for many 12V chargers, but as you say car voltage is somewhere between 13.5 and 16V, when the generator is charging :-)! > I don't understand why more handhelds can't simply be plugged > directly into a 12V power source and used without battery.

Thanks for the advice. Yeah, bit frightening actually! You'll find a lot about it if you do a search on the internet :-(!
