The QT-RTG is a power generation item in Astroneer that supplies a constant stream of power without any fuel needs. It is a smaller version of the RTG that takes up a Tier-1 slot, and can be put inside the player's backpack and used to provide 1u/s of power.
QT-RTGs offer a constant stream of power at all times and does not require fuel. It can be placed on most small slots, or on the ground(which makes a platform appear, like a lot of small items).
It is because of these reasons, that they are considered valuable.
A Portable Oxygenator will run indefinitely 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, as an RTG cannot fit on it.
A Medium Storage Silo filled with 20 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.
A QT-RTG may be used as a good starting power source on most planets, especially those with low power outputs, such as Atrox.
QT-RTGs can be used in combination with the VTOL and Small Battery to fly around planets and power up teleporters.
Trivia[]
The QT-RTG was first shown on the March 12, 2021, SES_Dev Twitch stream.
Because the QT-RTG only produces 1 U/s, the Portable Oxygenator's power consumption was changed from 2 U/s to 1 U/s for general convenience.
