MacBook Air Charger 45w vs 65w

Can you use a 65W apple charger instead of the 45w charger that comes with the Macbook Air? How will this affect the machine.

Solution 1:

Yes this is fine (assuming you refer to the 60W Magsafe) and this has been confirmed by Apple to be safe

Although you should always use the proper wattage adapter for your Apple portable, you can use an adapter of a higher wattage without issue.

This will not affect the Mac at all. It will not charge faster. It will not damage your battery. It will not damage your adapter.
