Here you can learn which power adapter cable and plug is compatible for your Mac notebook.
Power adapters for Mac notebooks are variable. For instance, 29W, 30W, 45W, 60W, 61W, 85W, 87W, and 96W. You should use the appropriate wattage power adapter for your Mac notebook. In this regard, you can use a suitable higher wattage power adapter without issue, but it can’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 guarantee that 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 "duck head"), 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.
Below images show the form and model of adapter that comes with each MacBook, MacBook Pro, and MacBook Air. If you're not sure which model Mac you have, use following elements:
Being sure that you're using the correct USB-C charge cable
When you really want to have the best charge, it’s better to use the USB-C charge cable that is compatible enough with your Mac notebook. If you take a higher wattage USB-C cable, your Mac will charge in a normal way but you won't experience an increase in the speed of charging speed process. As a matter of fact, USB-C cables rated for 29W or 30W will work with any USB-C power adapter, but won't make enough power when its connected to a power adapter that is more than 30W, like the 61W USB-C Power Adapter.
In this issue, you can easily verify that you're using the suitable version of the Apple USB-C Charge Cable with your Mac notebook and its USB-C AC Adapter So, you should be aware that 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 the Apple 29W or 30W USB-C Power Adapter.
- If the first three characters of the serial number are DLC, CTC, FTL, or G0J, the cable is for use with a USB-C Power Adapter of any wattage.
- 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 has got different size, color, shape, or wattage as the original adapter that came with your computer. But the point is that, it should power and charge your Mac exactly the same adapter that came with your computer originally.
