im using the aspire nautilus mini 1.8ohm on a volcano inferno 650mah 3.7v battery and 18mg menthol. i have already upgraded from 12mg nic about 2 weeks ago and now it takes around 6 sec drags to get a decent th.. (i use less than 2ml a day) im currently waiting on my aspire vv 1600mah battery to arrive and hopefully i will get better results. but right now im scared that taking long drags like this will burn out the coil, has anyone had a similar problem and please can i get some advice?
