Power Adapters
by jaredlll08
Power Adapter is a Forge block that converts between several energy systems, so machines built for one power type can draw from another.
What it does
The Power Adapter block accepts power from Tesla, Redstone Flux (RF), Forge Energy and Minecraft Joules (MJ) sources and converts it into the other supported types. Each type is converted at its own rate, with Tesla, Redstone Flux and Forge Energy at 25 power and Minecraft Joules at 100 power. The block is crafted from a recipe and is meant for modpacks that set up their own progression and balance systems.
The mod adds a single block and nothing else, so it can be dropped into a pack that already uses one of the supported power systems. Installation needs Bookshelf, which must be present on the same Forge setup. Installation covers the server and each player's game. Power Adapter is open source under the GNU Lesser General Public License v2.1 only and is published for 1.12.2 only, with the 1.0.11 Forge file as the latest release.
Key features
Four power types
The block accepts Tesla, Redstone Flux, Forge Energy and Minecraft Joules, covering the main energy systems of 1.12.2 mods.
Universal conversion
Power entering the adapter is converted into the other types, so one machine can feed several networks.
Per-type power values
Each supported type carries its own power value, which sets the rate at which it converts to the others.
Crafted block
The Power Adapter is obtained from a crafting recipe, which lets pack makers gate it behind their own progression.

Use cases
Modpack balancing
Pack makers can connect machines that use different energy systems and set how each conversion is valued.
Who it’s for: Modpack makers and server owners who run several power systems together and need them to share energy on Forge 1.12.2.
How it compares
Solar Village is also a Forge mod for 1.12.2 and is open source under the same GNU Lesser General Public License v2.1 only, but it adds generators rather than conversion. Power Utilities covers 1.12.2 – 1.21.1 on both Forge and NeoForge and is open source under the GNU General Public License v3.0 only. Smithing Table Adapter is for 1.20.1 – 1.21 on Forge and is not open source, so it is a different kind of adapter.
