E-081 is a trapizoid shaped electrical generator with a cylinder attachment connecting the wires, a button can be found to reset the generator.
E-081, like any generator, can be used to power entire buildings and electrical equipment, however it is not recommended to do such. Maintaining it requires high maintance and extreme attention. It can be recharged easily by pressing and holding the yellow button, giving it power. The drain rate speed is the same as its charge rate speed for unknown reasons. While engineers at WarioWare attempted to fix it, they made it drain quicker and charge quicker. The reset button does nothing. The generator itself was retrived during a global panic and used as an electrical component to defeat E-027.
