The Wall Connector is $500 and the Gen 2 Mobile Connector Bundle is $275. Not sure how almost half the price "isn't much cheaper."An extra cable isn't much cheaper than just getting the wall connector and you get the extra functionally with it along with it looking cleaner and better.
If I cared about such things, I could get a much cleaner installation using the $225 difference and still have money left in my pocket. The only thing I wouldn't have is the extra functionality and a little better charging speed (which in most cases doesn't make much of a difference). Also, with the Mobile Connector, you get six more feet of cable (which in my case would make a difference).
