i am completely new to vaping i have an eGo-V V3 Mega with an iSmoka BBC Mega Cartomizer tank. but every time i change my wattage or voltage, the ego automatically changes the opposite one, for instance if i set my voltage at 3.5 and my wattage to 14.0 it will automatically change the voltage to 5.2 and vice versa how can i change this?
