Do Star Wars blasters run out? Blasters fired bolts of energy. Most personal blasters had two kinds of ammunition: a gas cartridge and a power cell. Blaster gas cartridges could typically provide for up to five hundred shots before needing replacement. Most blaster power packs could supply energy for up to one hundred shots.
I searched up if Star Wars guns have to reload and it said No. Blasters create plasma without the use of lasers by supercharging gas (tibanna gas, specifically) and firing it out as a bolt. So blasters need both a supply of tibanna gas and a power pack. The E-11 blaster rifle (standard issue Imperial weapon) had enough energy for 100 standard shots per power cell
