Teleporter is an IC2 mod machine that links two units via a Frequency Transmitter and warps a player plus inventory between them for a distance-squared EU cost.
Guide
Combine one Advanced Machine Block, four Advanced Circuits, one Diamond, and Glowstone Dust on a Crafting Table to produce a single Teleporter block.
Set the first Teleporter at the origin base and the second at the destination, leaving the top face clear so the player can stand on it for transport.
Connect each Teleporter to an HV input — typically an MFSU through HV Cables — so the buffer can fill to the millions of EU that long jumps require.
Shift-right-click the source Teleporter with a Frequency Transmitter to copy its coordinates, then right-click the destination Teleporter to write the pair.
Step onto the source Teleporter; when the destination has enough EU stored for the distance and the carried mass, the Teleporter sends the player to the linked block.
Energy cost scales with the squared distance plus inventory mass, so a Teleporter chain of two short hops can be cheaper than one long jump across an IC2 base.
Place one Advanced Machine Block, four Advanced Circuits, one Diamond, and Glowstone Dust on a standard Crafting Table — the IC2 recipe yields one Teleporter block.
Use a Frequency Transmitter: shift-right-click the source Teleporter to copy its coordinates, then right-click the destination Teleporter to write the linked pair.
Energy cost scales with the squared Cartesian distance plus the mass of the player's inventory, so short hops cost only a fraction of what long, heavily loaded jumps drain from the buffer.
No — Teleporter is part of IndustrialCraft 2, a Java Edition mod, so the block does not exist in Bedrock Edition or in any official vanilla version of Minecraft.
No — Teleporter is an EU-powered IC2 mod machine for paired in-dimension warps, while minecraft:end_gateway and minecraft:end_portal are vanilla blocks tied to End-dimension travel.
