Power Cells are special items in Horizon Zero Dawn. Power Cells can be collected from a number of locations across the world to be used for the side quest Ancient Armory.

Power Cells also appear as a quest item in Heap of Trouble, though these are separate from the items collected for Ancient Armory.


There are five Power Cells scattered across the world that must be obtained to complete the Ancient Armory quest, with all but the first one being accessible during main quests.
