Yup. More coils = more juice being vaporised. The thing is though, you might not notice it as much as you think. Some coil dual heads have been designed in such a way that the wicks will be absorbing what looks like a a similar amount as a single coil. But, some coil heads (and RTA's) are known drinkers [emoji39].guys will a freemax tx2 coil use more juice than the tx1 both vaped on 45w
