Why is my charger not charging my iPad when it is the right charger

There could be many reasons for this. The block could have gone bad, the cord could have gone bad, the port on the iPad could have gone bad, or the outlet could have gone bad.

Mines stop working in abt two months after my iPad purchase. It won’t charge my ipad nor my iPhone 12.. it was less than three months old. So I’m not sure what went wrong ..
