I hv the Porsche one that sticks in the cigs lighter. (after a dead battery experience....)

 

so much more convenient than popping the hood everytime since I only drive on weekends hence it;s always lefting charging during the week.

and the cable is thick and shielded enough so I can even close the door once it is plugged in.  

cant tell which one is better (direct bind vs cigs lighter), but I doubt it makes a difference.
