Basic Energy Cube

The Basic Energy Cube is a machine added by Mekanism. It is the first tier of energy cubes and stores the smallest amount of energy compared to other tiers. The next tier up is the Advanced Energy Cube. The Cube can be also used as a charging station for items.

In addition to the cables from Mekanism (e.g., the Basic Universal Cable), the cables of all supported power systems can also be connected, such as the Cables from IndustrialCraft 2 (e.g., the Copper Cable), the Fluiducts from Thermal Dynamics (e.g., the Leadstone Fluxduct), and the Kinesis Pipes from BuildCraft.

GUI
Right-clicking on the block opens the Cube's GUI which shows its internal storage.

Inside the minus slot the player can place other loaded energy cubes and discharge them to load the Basic Energy Cube.

Inside the plus slot the player can place items and tools to charge them. It is also compatible with items from other mods like the RE-Battery from IndustrialCraft 2.

The upper-left button (called "Side Config") opens the configuration of the cube, where the player can set which side should receive or emit energy. If a side is disabled, the center of the side is transparent and no cable connects on this side. If the player holds the Configurator in their hand, the cube displays a color code on the side the player is looking at. Grey means "Off", red means "Output," and blue means "Input". Shift right-clicking a side will change its configuration.

With the lower-left button the player can change the displayed energy system between Energy Units, Redstone Flux, Minecraft Joules, and Tesla. The change only affects the display; the energy is still available in all forms inside the system.

The upper-right button configures the access rights for this block.

The lower-right button changes the Cube's behavior to Redstone. For example if the option is set to "High", then energy is only released when a redstone signal reaches the cube.
