T-Tip Adapter?

[beachmommy]

My daughter has a 2013 Macbook Air, it works just fine, she is leaving for college on Monday. I didn't realize that she has only one power cord, which plugs into the wall. I can't seem to find an adapter on Apple (maybe because it's older?) which will let her utilize the USB ports with a power pack for classes all day. Do I need to look to a third party seller?

Thanks so much!

The MacBook Air can only be charged using its Magsafe connector.
