Bulk inserter

Bulk inserter is an inserter item whose stack size is affected by the inserter capacity bonus research. Its default stack size is 2, and each level of the bonus increases the total stack size according to the researched capacity level.

The stack size can also be overridden to control how many items it picks up at once, but the maximum override is limited by the highest inserter capacity bonus technology currently unlocked. The total stack size progresses as follows: 2 with no bonus, 3 at bonus 1, 4 at bonus 2, 5 at bonus 3, 6 at bonus 4, 8 at bonus 5, 10 at bonus 6, and 12 at bonus 7.
