where to find a power cable for macbook air 13

For what model year of MacBook Air exactly. This is the 2006 to 2010 MacBook forum, which had the cable built into the charger brick.

Your tag line, reads you have a MacBook Air 2018 to 2020, which uses a regular USB-C cable, that can be found anywhere electronics are sold or at any Apple Store.

Don't know the exact info you noted. What I really need is the power adapter. Amazon keeps showing me charging cables.

Power adapter? As in the big brick you plug into the wall?

If so, again, most electronic stores have one for newer Macs, or you can buy it directly from the Apple Store.

To get the correct info for your Mac, open the Apple Menu, and select About This Mac. Then copy the model / year shown there and we can point you in the right direction.

If the Mac cannot turn on, look on the bottom of the Mac for the model number (starts with an A) and post it here.

Do not post the serial number here. Only the model number.
