Intel-Based Apple Portables: Identifying the right power adapter and power cord--US

Learn which power adapter, power cord, and plug are appropriate for each Intel-based Apple portable. Keep in mind that size, shape, and color of replacement adapters and cords may vary. 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.
Note: 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. 
If you are looking for a PowerPC-based power adapter please use the article PowerPC-Based Apple Portables: Identifying the right power adapter and power cord.
