Using the formula V² / R = P, where V is voltage, R is resistance, and P is power (in watts), what wattage do you prefer to vape at on your favorite juice delivery devices? I know that for me, it depends on what I'm using as a delivery device. 8.88 watts is just right for my 1.8Ω Vision V2/V3 Clearomizers (4 volts), 7.7 watts seems to be the sweet spot for my 1.5Ω AMG Hybrid Uni atty by Vapage (3.4 volts), and my 2Ω Smok Tech 510 atty provides its best performance at 8 watts (again, 4 volts).
