Watts Up For Laptop

Watts Up For Laptop

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 cableFor 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.
