Power adapters for Mac notebooks are available in 29W, 30W, 45W, 60W, 61W, 85W, 87W, and 96W varieties. You should use the appropriate wattage power adapter for your Mac notebook. You can use a compatible higher wattage power adapter without issue, but it won't make your computer charge faster or operate differently. If you use a power adapter that is lower in wattage than the adapter that came with your Mac, it won't provide enough power to your computer.
Mac notebooks that charge via USB-C come with an Apple USB-C Power Adapter with detachable AC plug (or 'duckhead'), and a USB-C Charge Cable.
Nov 02, 2014 I brought my charger for my 2.5 year old laptop to the Apple store because the cable had frayed, and because they saw the condition of the rest of the charger compared to the shitty condition of the cord, they replaced it free of charge, because it's a manufacturing defect, not.
Mac notebooks that charge via MagSafe come with an AC adapter with MagSafe connector and detachable AC plug, and an AC cable.

For the best charging experience, you should use the USB-C charge cable that comes with your Mac notebook. If you use a higher wattage USB-C cable, your Mac will charge normally but you won't see an increase in charging speed. USB-C cables rated for 29W or 30W will work with any USB-C power adapter, but won't provide enough power when connected to a power adapter that is more than 30W, such as the 61W USB-C Power Adapter.
You can verify that you're using the correct version of the Apple USB-C Charge Cable with your Mac notebook and its USB-C AC Adapter. The cable's serial number is printed on its external housing, next to the words 'Designed by Apple in California. Assembled in China.'

* Adapters that shipped with the MacBook Air (Original), MacBook Air (Late 2008), and MacBook Air (Mid 2009) are not recommended for use with MacBook Air (Late 2010) models. When possible, use your computer's original adapter or a newer adapter.

A replacement adapter might not be the same size, color, shape, or wattage as the original adapter that came with your computer. But it should power and charge your Mac like the adapter that originally came with your computer.
