can I use the power adapter in the US or do I need to buy an American one as well? My concern is the both voltage and amperage.

Answer

You can use the power supply in the US, all you need is the Apple World Travel Adapter part number MB974ZM from the apple store.

"The World Travel Adapter Kit includes a USB power adapter, a USB cable, and a set of six AC plugs with prongs that fit different electrical outlets around the world. For world travelers, this is the perfect kit to ensure power connectivity in most countries you may travel to.
The Kit is designed to work with iPod, iPhone, Apple MagSafe Power Adapters, Portable Power Adapters, and AirPort Express.
The AC plugs included in the World Travel Adapter Kit directly support outlets in North America, Japan, China, United Kingdom, Continental Europe, Korea, Australia, and Hong Kong."

It also works in countries not listed as many countries use the same outlet as those listed. I've yet come across a country I cannot use this kit in.
