Stack inserter

Stack inserter/infobox

The Stack inserter is an electric inserter that can move more items at the same time. It was introduced in game version 0.13, replacing the Smart inserter that had been made unnecessary by changes to circuit and logistics functionality.

Moving at the speed of the Fast inserter, it transfers multiple items per cycle to give it a material flow advantage at the cost of additional power consumption. When transferring between chests or cargo wagons it picks up and drops off the entire stack of items instantly. When picking up from or dropping off items onto a Transport belt a stack inserter needs to grab or drop each item individually, increasing the time between arm swings and lowering its potential throughput. In these cases, however, the stack inserter still has higher throughput than a fast inserter because it swings back and forth less often.

For more information on mechanics and uses see Inserters.

Stack size

The stack size is increased by the Inserter item stack size bonus technology.
