You don’t have a Mac that uses USB-C charging, or even has USB-C ports.

Here is the charger: Apple 45W MagSafe 2 Power Adapter - Apple

You may well have a power cord with a duck-head that connects to that MagSafe 2 charger.

Which exact model is your MacBook Air? What USB-C charging cord you would use will depend on which power adapter you have.

If it is a USB-C adapter, then you would need a USB-C to USB-C cord. On the other hand, if it is a USB-A adapter, you would need a USB-A to USB-C cord.

Not quite. That would be the version of macOS running on it.

You can find your Mac model by first clicking on the Apple Logo, and then, select "About This Mac." It should say something like Early 2015 MacBook Air.

Looks like MrHoffman got back to you before I could. He provided you the correct device to charge your laptop.
