Hello, I was wondering if anyone else was running over 12 watts on an istick 20w, I currently have the nautilus mini and full size tanks and found that it likes higher wattage. I'm using 30/70 pg/ Vg. Seems to kill the battery ALOT faster, especially when chain vapin. I'm lucky to get a full charge to last the whole day. I have a 30 watt istick coming Thursday, can't wait!!
