Astroneer Power Cells Guide: Recipe, Output, and Best Uses

Power problems arrive early in Astroneer. Printers stall, the Soil Centrifuge sits idle, and vehicles become very decorative. Power Cells are a compact emergency option for feeding energy to equipment that needs a quick boost.

How to Craft Power Cells

The Power Cell recipe must be unlocked first. Spend 800 Bytes, then craft a Power Cell from the Backpack Printer with:

• 1x Graphite

Graphite appears on every planet as dark, tube-like resource clusters. Use the Terrain Tool, bound to E by default on PC, to collect it.

There are also two reliable alternatives. A Soil Centrifuge can produce Graphite from two full Soil Canisters, and a Trade Platform can exchange 1x Scrap for 2x Graphite. Those methods are useful when local deposits are far from base or buried somewhere inconvenient, because naturally they will be.

Power Cell Capacity and Throughput

Each Power Cell stores 48 units of energy. It outputs power at 1 unit per second to whatever it is attached to. For comparison, that is enough throughput to fill one bar of a Small Battery in about 4 seconds.

Power Cells can also run vehicles, but the results vary heavily by vehicle size. One Power Cell can power a Buggy for about 42 minutes. A Medium Rover drains the same cell in only 96 seconds.

Vehicles consume attached Power Cells before using their own internal energy reserves. That behavior makes cells handy for mobile backups, but it also means they disappear quickly if left attached to something hungry.

Important Usage Notes

Power Cells are consumable. Once their stored energy is gone, the item vanishes. A partially charged Power Cell placed in the backpack will discharge almost immediately and disappear, so avoid treating them like reusable batteries.

They are best saved for early exploration, emergency vehicle power, or short machine operation away from a proper grid. For permanent bases, build renewable power and batteries instead. Power Cells are a bandage, not a power plant.
