Got a tip for us?
Let us know

AC cord is replaceable with the little adapter on the magsafe charger. There are no 2 chargers.
The cord is just an extension. If you want a longer cord, remove the pins on the power supply like that:
And connect the extension cord instead. Most people I know use the extension, but you may prefer not to use it for more portability. It's just a matter of how long of a cord you need, it makes no difference on charging itself.

Actually the electrons have further to travel which increases the resistance and reduces the efficiency. Over the lifetime of the MBP we are talking hundreds of gigawatts wasted.
If you'll be using your charger in a public place where other people plug in, please switch the connector out to use the cord. I've been in many libraries where electric outlets couldn't be used because someone had to plug their entire brick into an outlet, covering up the outlet beside it.
That's terribly exaggerated. Your MBP itself will probably never use a full megawatt during its lifetime. Waste because of the extension is negligible. Charging time is the same.
OP dont worry about the megawatt and gigawatt posts listen to the people that said its to make the cord longer, thats the correct answer
If all else fails, RTFM:

Or sarcasm.
