EU storage block
Storage blocks will only retain 80% of their EU when removed. Chained storage blocks (i.e. wired to other storage blocks) can be used to avoid cable loss on lengthy transmission lines; however, the material cost of crafting another storage block may well outweigh the extra 1 or 2 EU per packet you would otherwise lose.
