Here you can learn which power adapter, cable and plug works with your Mac notebook computer.
As you may know, power adapters for Mac notebooks are ready in 29W, 30W, 45W, 60W, 61W, 85W, 87W and 96W varieties. You can use the suitable wattage power adapter for your Mac notebook. You can use a well-matched 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 prepare 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 following pictures show the style of adapter that comes with each MacBook, MacBook Pro and MacBook Air.
Make sure you’re using the correct USB-C charge cable
In order to the best charging experience, you can 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 prepare enough power when connected to a power adapter that is more than 61W, such as the 96W USB-C Power Adapter.
It’s better to 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.”
when 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.
when 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.
when 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.
