If you are telling us that you need a new charger for your MacBook Air......like the example below......you can order the product from Apple or visit an Apple Store.

Most Best Buy stores also stock Apple accessories as well.

If this is not what you are looking for.......we will need more details to try to figure out what it is that you need.

This is posted in the AirPort Wi-Fi forum, discussing a “charging port”, and it’s not clear to me if this is a request for a repair (to a Mac?) or a request for a replacement charger.

If it’s a Mac charger, the Apple Store sells those for any recent Mac. Use the Mac link at the top of the page, and select accessories.

If it’s a request for a repair for a failed port, use the Get Support link in the upper right, and discuss your options and alternatives with Apple.

If it’s something to do with an AirPort or AirPort Express or AirPort Time Capsule, some more details would help.
