It's 15v only - with a soap-on-a-rope adaptor in line - and has a car power adaptor, and then an adaptor from *that* to the in-flight connector. Oddly, the car adaptor is just too small for my car (Fiat) power point, so I have to wedge it a bit :) Sometimes the pretty green light goes out, but it still seems to work. It throws out RF but not enough to obscure - and as I tend to use it to listen to MP3 on the move, it doesn't matter. I dunno if it works on planes, I never get to sit in the expensive seats with power :) btw - it's probably not stable on 1.5A power supply because the effective output impedance is too high...1.5/12v equates to 1.2/15v and that's not really enough to run the lib...plus switch modes don't like (usually) to run without a load, it upsets their regulation. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp. ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://libretto.basiclink.com/archive - Archives http://www.picante.com/~gtaylor/portable/faq.html - FAQ -------TO UNSUBSCRIBE------- Reply to any of the list messages.
