Astroneer Wiki

Hello all editors and users of the Astroneer Wiki! We are in the process of updating and switching over to use the new Fandom Desktop skin on the wiki. There will be many changes over the coming days, but the main goal is to keep the wiki feeling the same, as much as we can! If you notice any issues once the swap is made, please post them to the Admin Noticeboard so we can address it right away. We are also going to be completing the update to the Astroneer Wiki:Style guide, so there is a more up to date guide on how to style the wiki going forward.

The Medium Generator is a power generation item in Astroneer and consumes Carbon to produce power.


Output Input Module
Medium Generator Tungsten
Small Printer


  • Power Production Rate: 9 U/s
  • One Carbon will fuel the Medium Generator for 120 seconds and produce 1,080 Units.

Once plugged into a socket on a platform or storage, the generator will convert Carbon over time into Power. The Medium Generator will not slow down Carbon consumption if nothing is available to use the power it makes, so caution should be taken to avoid wasting fuel.

The Medium Generator can be turned on and off by hovering over it and pressing the Use key (default F, Xbox One - Y Button, or PS4 - Triangle). Carbon won't be consumed when turned off.

Power output may be automated by placing the Medium Generator on a platform with storages attached that contain Carbon. When one nugget has been used up, the next will be pulled until all nuggets have been used up, at which point the generator will no longer produce power.


  • When planning for long trips, Carbon has the highest consumable power yield per single T1 slot of any item in the entire game, with a few exceptions;
    • The tier 2 slot that a Medium Generator takes up is effectively 24 tier 1 slots that could be used by Medium Storage Silo to hold Organic and Small Generators.
    • Consequently, it's possible to carry more energy per storage space used by placing Organic instead of Carbon if space is limited.
    • The ratio flips above 12 spaces used; 12 T1 spaces worth of Organic or Carbon produce almost exactly the same amount of power, including the overhead of the space the generator takes up. An easy way to remember is that if you must carry more than 12 Organic for portable power, you will be able to store more total energy by using a Medium Generator instead.
    • For longer one-way trips, it might be viable to simply package a Medium Generator back into its original T1 box, or fabricate a new one by bringing materials along.
