That was the ABV from about 5 min on standard and 5 min on boost, till there was no vapor left. Last night from a full charge I got about 3 20min cycles. I kept pushing the button to keep it on. TheRealVaporBlunt stated that it takes much more energy to heat up the unit than keep it at working temp. Makes sense. They claim 120min continuous use on one charge. I have noticed that my unit charges really fast. About an hour and a half from the low bat red flashing button.
