The number of puffs of an Elf Bar depends primarily on the amount of e-liquid used. As a rule of thumb, 150 to 300 puffs are possible per milliliter of liquid. So an Elfbar 600 with 2ml of liquid offers between 300 and 600 puffs, and with an Elfbar 1500 you can expect between 750 and 1500 puffs. An Elfliq e-liquid should offer between 1500 and 3000 puffs of the flavor of your choice.
