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. Lifepod 5 also uses a 3 power cells which self-charge. This power cell is not able to be removed from the Lifepod or crafted. The Destroyed Lifepods also use self-charging power cells, although they are inactive due to the trauma occurred when destroyed.

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. If one lacks a Power Cell Charger, a workaround is to recharge Power Cells using a Seamoth and Moonpool, which will also recharge the Seamoth's equipped Power Cells.
