[Star Wars] How do blasters work in terms of ammunition?

Looking at the Star Wars movies, we NEVER see anyone reloading or even saying they need a new weapon. 

Is the ammo capacity infinite or what?

Some of this is sourced from Legends, but basically, your common blaster has two consumables: blaster gas and a power cell. There are multiple types of gas, including tibanna, which is harvested on Bespin. The different types explain the different colors of blaster bolt you'll see. As far as power cells, they're essentially a battery. There are some that are rechargeable and some that are disposable and replaced. With both the gas and the cells, however, a full load typically lasts long enough that you won't need to address it in the midst of a fight.
