I use a Kgo 1100mah battery and normally just vape with a simple ce4 clearomizer I get from my local B&M. But recently I purchased a Smoktech Duel Coil Ego Cartomizer. It's really quite nice and it REALLY brings out the flavors of my liquids. It's only 1.6 ohm so it seems that it wouldn't use up a lot of energy but I notice that when I use it, it does seem to drain my battery faster than the clearomizers do. Is this because it's a duel coil? Is it really using more power to produce the vapor? This concerns me because I don't want to cause any damage to my batteries. Would someone please give me your opinion as to whether or not damage can occur?
