Its an Aspire Atlantis EVO standard kitYup.. 5 or 6 years ago, whatever you bought would barely qualify as a usable e-cig - it was all E-Lites and Nicolites (Skycig) and they were absolutely useless and incredibly expensive. Those rip-off merchants put as many people off e-cigs as converted them. Clearomisers (plastic tanks) were rare in those days.
I suspect you have just used up the coil. In most cases a new coil fixes things.
Then again, in the same period of 5 years, there have been lots of tanks (or clearomisers) that don't really work so well. The exact name of your tank (clearo) would help lots.
It got a 0.40 coil in it 40-50w so it says on box
It also has a spear coil which is 0.50 35-40w
