In reading the manual for my 2010 XK, I found that the cigar lighter should NOT be used to charge phones or other electrical devices. The same goes for the 12 volt connection in the glove compartment. That's news to me. I wonder how many of you routinely do this? And could that be a cause of some of the electrical gremlins we occasionally experience?

 

This is the text from the manual:


An electrical accessory socket is located inside the glove compartment. This 12 volt socket should only be used for the temporary connection of electrical items, such as a vacuum cleaner or cool box.


CAUTIONS

Only Jaguar approved accessories

should be plugged into the power

sockets. Using any other equipment may

damage the vehicle's electrical system. If you

are in any doubt, contact a Jaguar Dealer.

The engine should be running when

using accessories for long periods.

Failure to do so can discharge the battery.


This is just a legal disclaimer. There are all manner of accessories and some, such as power inverter can overload the wiring. Also, if an accessory causes a fire this absolves Jaguar. As long as the engine is running, or just a few minutes with the engine off, the small drain from a charger will not cause any problems.

 

I have had my Garmin GPS plugged into both 12v outlets for long periods of time(months) without any noticeable problems
