Are the power adapters that come with android boxes usually cheap?

[AC Question]

One of the prongs on the plug of mine, literally fell out... I managed to put it back in, and the box worked for about a week, but now it wont turn even turn on...
Do i need a new adapter?

Replace the adapter might Not necessary. But better
in this case--Buy the whole brand new charge
Set from the manufacturer. Don't provide
