The compatible AC adapter for Macbook Air is broken. It seems that the base of the connector on the main body side is broken. I thought about buying a new compatible product, but in the reviews on Amazon's site, it seems that there are many losses, so I decided to buy only the connector and repair it.

Amazon has a cable with a connector and a DC jack that can be used with a mobile battery, so I made it with a DC jack.

When I attach the jack to the one with the disconnection, the repair is complete. The DC jack was only black, so I painted it white after checking the operation.
