cigerette sockets

[stevieh1968]

i am looking for some info as to maximum usage for a cigerette socket. i have a ceramic demister i want to plug in 12v 150w. the socket states 12v 120w max. is there any way to increase this

The limiting factor is the the thickness of the wires that connect the socket to the battery.
If you want to draw more current then the wires need to be thicker. It's rated for 10amps and you are asking it for 12.5amps
Amps x Volts = Watts

Might also be limited by the size of the fuse, as in it'll be on a 10amp fuse!

That's quite a lot to draw from the rather stty cigarette socket that we seem to be stuck with, you could look to hardwire it in (with a fuse, obviously) for reliability?

On subject does anyone know if there is any movement in the industry towards an in car power socket standard that is actually fit for purpose? Maybe with the inevitable move to higher voltages we'll finally get one.
