JimJamie Posted April 9, 2009 Share Posted April 9, 2009 Can this be done? My 20 minute drive to work is not enough to charge my cell phone. Why doesn't it charge when the car is off? Link to comment Share on other sites More sharing options...
Max713 Posted April 9, 2009 Share Posted April 9, 2009 Because the 12v power supplies turn off when the key is off. Link to comment Share on other sites More sharing options...
JimJamie Posted April 9, 2009 Author Share Posted April 9, 2009 Can this be re-programmed? (should have been my first question) Link to comment Share on other sites More sharing options...
katalyst Posted April 9, 2009 Share Posted April 9, 2009 ^ no, you will drain your car battery and thus be stranded after work. bring the phone charger and plug in at work? Link to comment Share on other sites More sharing options...
greenleg88 Posted April 9, 2009 Share Posted April 9, 2009 Can this be re-programmed? (should have been my first question) its not programed to do this.. its physically wired liek this but yes you can rewire it... but like ^ said, you will drain the battery... i feel like it would just be easier to buy an "aux" socket from pep boys and something.. and then nicely wire it directly to your battery from inside the car. (with a fuse of course) cuz then you could have a dedicated phone charger all the time. hah. but of course that would kill your battery if you ever forget it for long enough. also... why dont you just charge it before the drive to work.... like at night or something.. that is if you work in the morning... and how will charging your phone after the car is off help if you have to park your car and leave it anyway...? unless you plan on leaving it in your car to charge while youre gone...

RustyShackleford Posted April 9, 2009 Share Posted April 9, 2009 no, you will drain your car battery and thus be stranded after work. Incorrect - you would have to have a phenominally weak battery for 8 hours on a cell-phone charger to drain it. You COULD do like me and add an always-on cigarette lighter outlet. Use this cool socket: http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=265-274 ... and mount in on the passenger side of the center console forward of the seat (kinda below and to the side of the ashtray) or whereever else floats your boat. If you inspect the wiring diagrams, certainly there's an always-hot 12vdc wire back there somewhere (one on the head-unit harness). I ran a dedicated 8-guage wire direct from the battery, like you would for an amplifier, because I wanted to be able to run a 100-200watt inverter (yes, that WOULD drain the battery if left running very long !) This is probably more than you wanted to know and more than you want to do ... Link to comment Share on other sites More sharing options...
JimJamie Posted April 9, 2009 Author Share Posted April 9, 2009 I've owned a lot of cars where its factory hard wired to the battery. Since personal electronics stop charging when full, it would take weeks or months to drain the car battery. This was bad design logic on the part of Subaru.

nka Posted April 9, 2009 Share Posted April 9, 2009 The rear on of mine is always on and auto-turn off if the batterie is 9V or lower. Front is on with key only. Link to comment Share on other sites More sharing options...
rtbrjason Posted April 9, 2009 Share Posted April 9, 2009 I know one of mine works too with the key off. Not sure if it is the aux in the armrest or the cig lighter, but I can check. Link to comment Share on other sites More sharing options...
