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:

Repair: Apple MacBook MagSafe Charger Power Cord: Apple really dropped the ball on the design of this charger. The wimpy wire used in the design is simply to weak to take any real stress, coiling, and yanks. Eventually the rubber sheath separates from the MagSafe connector or the Power-brick. The cable came out of the MagSafe plug on my MacBook power supply, so I ordered a replacement cable. This is how to crack the power supply open and fit it, n. Resetting the SMC on Mac portables with a battery you can remove. Shut down the computer. Disconnect the MagSafe power adapter from the computer, if it's connected. Remove the battery (to remove the battery - click here: MacBook or MacBook Pro). Press and hold the power button for 5 seconds. Release the power button. If you bought a charger or a used or refurbished Mac online and your charger doesn’t work upon first use, make sure you have a compatible charger type. Apple has more information about the.

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.

You can get extra or replacement adapters with AC cord and plug at the Apple Online Store, an Apple Reseller, or an Apple Store.
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.

If you’re upgrading from a pre-2016 MacBook to a 2016 model or later, you may find it strange that the MacBook automatically powers on when you open the lid. This also occurs if the computer is turned off and the charger is connected.
While this may be a feature loved by some, it’s not appreciated by everyone. I really don’t like the idea and had to disable this feature on my MacBook Pro 2017. I want to be able to plug in the charger without having to worry about the MacBook Pro automatically turning itself on. You might just want to open the lid to clean the MacBook and it’s already trying to boot up.
You can’t do this from the settings, it has to be done through the command line. To disable this feature, it’s only a single line of code in Terminal.
How to disable autoboot on lid open or adapter connection
1. Press Command (⌘) + Spacebar to launch Spotlight search. Type Terminal and launch when it appears.
2. Copy this code or type exactly as shown below:
sudo nvram AutoBoot=%00
3. Hit Enter and you will be required to enter your password:
This should stop your MacBook pro from automatically turning on when the lid is open or when the charger is connected. You now have to use the power button / Touch ID button to power on the computer when needed.
Re-enable boot on lid open
If you need to re-enable this feature, you still have to do it through Terminal. You only need to use a different code.
