macbook pro not charging

i know i can go to an apple store and they will sort this for me, but i cannot get there for maybe 1week so i need something which will help temporarily:)

i have a macbook pro and its charger, and a macbook air with its charger but none of the chargers work on either laptop

i tried to restart computer, clean chargers, loads of other things but can someone give me something that will keep it working without voiding my warranty till i can get to apple store in about 1 week =) thanks
