My latest 2 cars, both Toyota and 4+ years old, have two-prong 110 AC outlets that can source about 1 amp before the fuse blows.
Now I want more amperage so I can design spreadsheets on my laptop while brewing coffee and watching TV on the way to work.! Lauren - external use - Save paper and trees!

I don't understand why cars still don't have specialised sockets for electronic equipment. The cigarette sockets likes to lose contact (it is my experience). Piotr Galka ----- Original Message ----- From: Scott Xe <mailto:scott...@gmail.com> To: emc-p...@ieee.org <mailto:emc-p...@ieee.org> Sent: Monday, January 19, 2009 2:38 PM Subject: Cigarette socket in vehicles I have learnt that cigarette sockets supply two voltages: 12 or 24 volts. 12-volt sockets are widely used in light duly vehicles while 24-volt sockets in heavy duty vehicles. The sockets are identical in terms of configuration and dimensions. Is there any mechanism to prevent a 12-volt equipment from being plugged in a 24-volt socket?
