Basic Energy Cube

The Basic Energy Cube is an energy storage added by Mekanism. It is the first tier of energy cubes and stores the smallest amount of energy compared to the others. The next higher tier is the Advanced Energy Cube. Furthermore the cube can be 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. So the Cables from IndustrialCraft 2 (e.g. the Copper Cable), the Fluducts from Thermal Dynamics (e.g. the Leadstone Fluxduct) and the Kinesis Pipes from BuildCraft can be connected to the cube.

GUI
With a right-click on the block the player can open the GUI of the cube, which shows the internal storage.

Inside the minus slot the player can place other loaded energy cubes to load the placed cube.

Inside the plus slot the player can place items and weapons to load 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 his 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". With a shift-right-click the player can change the configuration of each side.

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.

With the upper-right button the player can configure the access rights for this block.

With the lower-right button the player can change the behavior in conjunction with Redstone. For example if the option is set to "High", then energy is only released when a redstone signal reaches the cube.
