If I'm at a concert and handing it around probably the night, but you go through about 1 1/2 grams in the night. If I'm using it for daily use probably about three days. It has replaceable coils, you can clean them in between, the dab tool takes about .05 to .1 grams max and you can get 3-4 giant hits if you want or just hit on it slowly and have it last all day sometimes. You know, depends on the day and the dumb ass you're dealing with. No special charging cord just a micro USB plug, charged quick enough for me. Usually over night. It's just a little fatter than your standard 510 thread ego battery. I promise..... I don't work for them 😂🤣
