TNT Spawners are used to automatically generate TNT over time. They can be used to create TNT farms, redstone machines, and other automated systems on your island.
TNT Spawners require power in order to function. If your power network does not have enough capacity for the spawners connected to it, they will not run properly.

TNT Spawners have five tiers. Higher-tier TNT Spawners produce TNT at a faster rate than lower-tier spawners. This means less time between each TNT spawn, allowing larger setups to generate TNT more quickly.
Each tier also requires more power to keep running. Higher-tier spawners are useful for increasing TNT output, but they will put more load on your power network. Make sure your island has enough power generation before upgrading too many spawners at once.
TNT Spawners can be connected to Power Switches. This allows you to control when your TNT Spawners are active using redstone.
Power Switches are useful for creating more advanced TNT setups, such as automated farms, timed systems, or redstone-controlled machines.
When the Power Switch is on, the TNT Spawner can receive power from the network. When the Power Switch is off, the TNT Spawner will be disconnected from that part of the network.
TNT Spawners can be crafted in the workbench. Every tier above Tier 1 requires the previous tier spawner, as well as additional crafting components.
Each upgrade increases the speed of the spawner, allowing your setup to generate TNT faster as your island progresses.
