Storage Container

Storage Containers require much more physical space than Personal Storage Boxes and store slightly less items. Don't write them off though - unlike boxes, containers are automatic and allow for bigger factories - and bigger is better!

The more advanced Storage Container Mk.2 costs more, stores more, and is even bigger.

Stacks and ladders
It is easy to build and stack containers on top of each other (select it in the build menu and point at an existing container). Note that, when stacking containers, the input and output sides alternate every level by default (each container is spun 180° from the one above and below it). To change this and make them face the same direction, rotate the hologram before constructing each successive container.

Like most structures, containers have ladders on the sides so you can climb on top. You can even climb all the way up a stack of containers with their combined ladders! Try building a makeshift ladder with a tall stack of containers to reach high places in the early game. (Containers unlock before stairs, stackable conveyor poles, and jump pads.)

Automation
Naturally, if you connect a belt into a container, it picks up and stores all input items until full; if you connect a belt out, the container pushes all items out until empty. Connect both sides to pass items through and buffer them if there is a backup down the line.

If you link containers in series (output of previous to input of next), the last container always fills first, and the first container fills last. Connect them in parallel with splitters and mergers to fill them at the same time, but be mindful of different split ratios!

The type of belt determines the max speed of storage and extraction; containers will always work as fast as the belts can.
