Connect your power adapter and cable

To charge the battery on MacBook Air, you can connect the included USB-C to MagSafe 3 Cable to the MagSafe 3 port, or connect a USB-C Charge Cable to any of the Thunderbolt ports. Connect the cable to your Apple power adapter or other compatible power adapter, then fully extend the electrical prongs on the AC plug of your adapter and plug it into an AC power outlet.
