Yep, precisely this @VapeLuvr , remember the other day when you posted the picture that showed something like 2.4v? My suggestion was pretty much the same as brewbears, though I think I said start around 3.5v, with subohm coils it is almost certain you will need higher than that to get a satisfactory vape. Yes, with many of the true Tootle Puffer coils you can get away with lower voltages but on a subohm coil I often wind up closer to 4v, and some of the fancier* coils will need more than that. So starting somewhere around 3.5 to 3.6 Volts should be a good starting point. The .3 and .5ohm eleaf coils both suggest 30w as the low end of the wattage range.
*fancier in this case is referring to anything other than a basic single wire coil
