A king possesses the powers that his subjects give him (or maybe tolerate in him).
Most extant kings are "Constitutional Monarchs" which means that an elected government passes laws which the monarch then signs. Generally this type of monarch does not have the veto power that is possessed by an American president. He is the head of state, but this is a purely symbolic thing.
In complete contrast, early kings were "Absolute Monarchs". Bluntly put, the king told people what to do. Those that didn't obey lost their property, and sometimes their heads as well.
