Powers start out at full power. They will not get stronger but that doesn't mean you know how to use them right off either. Most of them are going to realize quickly that the powers are tied to their emotions so there will be a trigger they have to find to make them work. Fear, Joy, Anger these would trigger the power.

And if you teleported into the side of an active volcano you better trigger it fast to get out of there. :)
