Power Cell (Subnautica)

The Power Cell is a crafted item in the electronics tree of the Fabricator. It is a large power source that depletes over time in Survival mode, primarily used to power submersibles; the Seamoth the Cyclops and the PRAWN Suit all require one, six, and two power cells respectively.

The Power Cell is also used in crafting the Mobile Vehicle Bay. To replace a Cell, click on it and choose to either remove it, leaving the space empty, or swap a fresh Cell from your inventory in its place. The removed cell can be recharged using a Power Cell Charger.
