will a lower wattage affect how my macbook pro charges

My roommate's power cord got mixed up with mine and I won't be seeing her for 3 weeks. She has a macbook air while I have a macbook pro. I have noticed that her power cord works on my computer, but it just takes longer to charge and sometimes it stops charging? will using her power cord for the next couple of weeks affect my macbook? should i go to the apple store and get a new power cord? help please!

*I understand that I can mail her the power cord but since I will be seeing her soon I just rather not go through the hassel.*

MacBook Pro, iOS 5.0.1

Power adapters for Intel-based Apple portables are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple portable, you can use an adapter of a higher wattage without issue.

For instance If you have a MacBook (13-inch Late 2009) that normally uses a 60W adapter, you can also use an 85W adapter with that computer. You would not use a 45W adapter with that computer; it would not provide enough power for that MacBook. Using an adapter of higher wattage than the adapter that came with the computer will not cause the computer to charge more quickly or otherwise operate any differently than using the adapter that came with the computer.
