I have an iPod Nano that I charge by plugging it into my laptop. How can I charge it without the computer?

Ya, you can buy a wall charger that you connect the USB cable to. An example is in my source link. There are many out there.

Yup! Apple has an official USB Adapter (but it costs $29...you get another connector cable too, though=P)...it's this small square thing that has a plug at one end and the other end is where you stick the USB into (though it comes with one).

This allows you to charge through the wall.

I think you can charge it by plugging it into an Xbox 360, but maybe that only works with the Zune, but your best alternative is to get a wall charger.

yes u could actually by an adaptor at a near by electrocnic store.

Get a CD/iPod player

I have one, and it charges it while playing music.

Alternatively, you could buy a wall charger

you can plug the usb chord into a PS2

its slower to charge but it works...the PS2 has to be on though

Well i dont know about that, but i do have an alarm clock for your ipod that charges when you put it on there

you can buy a charger that plugs into a wall outlet

Yeah, just look on ebay....they're incredibly cheap

yes, you can purchase it at the apple store or im sure online
