Can I use the 45W adapter to power my 13" MacBook Pro?

I've read that I can use the 45W adapter from my old MacBook Air to power my 13" MacBook Pro, but that it will only provide power and not recharge the battery. True? Safe to do?

    It does work though. My friend has a 13" MacBook Pro and we have charged it using my 45W adapter that came with my MacBook Air.

  • I wouldn't use it. All 13" MacBook Pro ship with a 60 W power adapter. You probably could step down fro 85 W to 60 W because the 85 W would provide enough power, but there's no way for a 45 W adapter to go up.
