So I misplaced the default (tiny) AC charger

[Haeralis]

What I mean by this, is I lost the part of the charger that plugs the power brick directly into the wall. I still have the extension cable, so I can comfortably charge my MBP, but I'd like to replace the smaller AC plug (can someone tell me what its actual name is?)

I don't see it listed on the apple site so they may not sell it separately. There is one that comes with the Apple 12W USB Power Adapter for $19.95. Or you can buy another power supply.

You can get this thing, called "duck head" also from 3rd parties:

You can buy the service part directly from Apple, but you'll probably have to call them. They may have them available at the Apple Store.

I'd give apple a call, or just search on amazon. Both will yield the results you're looking for.

You can get them all day long on ebay for a less than $5 including shipping. I had had to order a couple of them for some MacBooks I was refurbing.
