Accumulator

The accumulator is a block used to store energy. It has 5 input sides, marked by a diamond shape, and 1 output side, marked by a square. When the input side of one accumulator is connected to the output of another, it automatically pumps the maximum amount of energy from it. The input can also be connected to a dynamo or solar panel. The maximum energy stored is 10 000 J.

The output side of an accumulator can be changed by right-clicking it while olding a screwdriver. The default output side is down.
