I have a 15 inch Macbook Pro.
My mom has a 13 inch Macbook pro.

Our charger DC converter boxes are slightly different sizes.

Is it okay to use her charger on my computer and vise-versa?
Anyone know if any damage will be caused, thanks.

    I believe the difference is between an 85W and 65W adapter. Basically, the 15 inch MBP can draw 85W of power, and the 13-inch can draw 65. Since the voltages are the same, if you use the 65W on the 15-inch, it will charge slower than it usually would with the 85W. However, if you use the 85W on the 13-inch, the computer will only accept 65W of power, and will charge at the same rate that it usually does.

    In non-nerd terms: the 85W adapter is the better one to use, as both computers will charge as fast as they usually are supposed to.
