Does the amp of a wire have to be higher than the amp you're giving it?

I am trying a project where I divert power from an ipad charger. I found this about the charger: iPad Charger 5.1 volts 2.1 amps 12 watts.

I was going to buy this wire:

http://www.amazon.co.uk/Brimal-Equipment-rolls-0-6mm-CB067/dp/B0071KZV74/ref=sr_1_1?s=diy&ie=UTF8&qid=1406495003&sr=1-1

But then I saw:
Current Rating = 1.8 Amps, max Voltage Rating = 1000 v

I don't do this kind of thing a lot, but even to me that seems like it wouldn't work.

Please could you tell me if I am wrong or suggest a suitable alternative wire (I don't need a lot and would like it reasonably cheap).

Thank you
