Charge

From The StarCraft 2 Wiki

Charge is a revolutionary ability that has been given to the Protoss Zealot. When researched, it enables the Zealot to quickly close the gap between itself and its adversary. A must-have for any Zealot army!

It is particularly useful when chasing down enemy units or closing the gap between the Zealot and a ranged attacker. Charge is triggered automatically when approaching an enemy unit, however, cannot be used to allow the Zealot to quickly escape from a hostile situation.
