12V "always on" socket - Benzworld.org - Mercedes-Benz Discussion Forum

Hi

I own a A-180. I have a couple of 12V sockets in the car. I need one of them to be "always on". At the moment they all only function when the ignition is on.

(I need to run a 12V fridge while camping as well as charge my cellphone when the car is locked.)

Any ideas how to do this? Any reason why it was designed this way? Is there a big risk to have it always on?

Regards
Kuifie

so you cannot accidentally drain your battery.

Take care & enjoy camping,
