    Is there a difference in voltage or something? I tried searching the forums but couldnt really find anything. Ive never had a MAC so I dont know the difference. Im just wondering if I use the power adapter and the AC plug instead of the AC cord do I get the same voltage? What is the difference? I'd like to put my AC cord away as it collects dirt. Thanks

    They both work the same, the cord acts as extension depending on the location of the outlet.

    Depending on your location, the cord is grounded where the other thing is not.

    Its all the same. Some people (like myself) like the added length of the cord. Others like to be able to wrap everything up around the tabs in the square, and opt to leave the cord extension off.

    The ground won't make a difference for your laptop or performance or anything. It's all 16.5 VDC after the transformer. The ground wire is only there on the cord to ground the the cable if the shielding gets broken and it starts shorting out. Since there's no cord that can break with the short two prong part used, only two prongs are needed.

    It does make a difference in areas with high electrical charge and could potential save ones life. This is covered in an electrician 101 class.
