Some artifacts, such as Gauntlet of Power, have triggered mana abilities. A triggered mana ability is a triggered ability that could produce mana as it resolves, triggers on the resolution of an activated mana ability or on mana being added, and doesn't require a target.

Most mana abilities found on artifacts are activated mana abilities. An activated mana ability is an activated ability that could produce mana as it resolves, does not require a target, and isn't a loyalty ability.
