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.

Type Power Generation

The QT-RTG is a power generation item in Astroneer that supplies a constant stream of power. It is a smaller version of the RTG that is able to fit into a player's backpack.


The QT-RTG may only be acquired from completing certain Missions (13 total) or found rarely on certain planets, either in EXO Dynamics Research Aids that require Astronium or specific wrecks.

In Creative Mode, QT-RTGs may be crafted using Nanocarbon Alloy.

QT-RTGs are also given as rewards in the EXO Request Platform.


QT-RTGs offer a constant stream of power at all times, and can be placed on platforms, the player's backpack, or on the ground.

  • Power Production Rate: 1 U/s
  • A Portable Oxygenator will run infinitely when paired with a QT-RTG, removing the need for the player to connect to Oxygen networks.
  • A QT-RTG can power any of the Rovers indefinitely, even underground. It is the only infinite power source for the Buggy due to the fact that an RTG will not fit on it.
  • A Medium Storage Silo full of QT-RTGs can create an incredibly dense power source that can easily power an Atmospheric Condenser, making gas collection much easier.
  • A Hoverboard may be paired with a QT-RTG to allow infinite movement.


  • The QT-RTG was first shown on the March 12, 2021 SES_Dev Twitch stream.
