@teefowl no you do not. Without seeing which plug you are taking about (make or female end) it is difficult what you have going on here but from your description “wall clock that says AC12V 820mA” it sounds like you are looking for a barrel connector. Those are not bound by the mA just by the counterpart (barrel size) of the plug. Post some good pictures of the adapter and the plug that needs replacing to verify this. [guide|21499]
