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.
Mac notebooks that charge via MagSafe come with an AC adapter with MagSafe connector and detachable AC plug, and an AC cable.
The images below show the style of adapter that comes with each MacBook, MacBook Pro, and MacBook Air. If you're not sure which model Mac you have, use these articles:

Make sure you're using the correct USB-C charge 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 still charge normally. 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 61W, such as the 96W 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.'
- If the first three characters of the serial number are C4M or FL4, the cable is for use with an Apple USB-C Power Adapter up to 61W.
- If the first three characters of the serial number are DLC, CTC, FTL, or G0J, the cable is for use with an Apple USB-C Power Adapter up to 100W.
- If the cable says 'Designed by Apple in California. Assembled in China' but has no serial number, you might be eligible for a replacement USB-C charge cable.
