note, i haven't gotten this mod, so i don't know what exists. I don't have it because i have a mod called BigBags which increases stack size of everything 20x.
Portable Boiling factory: Takes water and fuel and turns it into energy. 1x1 space. Equal water demand/fuel demand as a max efficiency boilers/engines setup. Useful for compressed coal.
Portable Clips: Many times as much ammo stored, same space used.
Even bigger guns: 100x pistols OR 10x SMG = machine gun. 100x machine gun = gatling gun. Machine gun fires 30 times per second (Once per 2 ticks) and Gatling gun fires 60 times per second (Once per tick!) except it takes ammo 5x as fast as normal, and deals 5x dmg. Good simulation of 300 shots per second
