hey guys. I'm really excited right now. i went to my vape shop and picked up an taste VTR. it seems really well built and i love everything about it. the atty it came with reads at 2.1 ohms. with that resistance i would typically vape at around 4.3 volts. I've never had variable wattage on a device before so i don't really know where to set that at. i know that matching wattage, voltage, and resistance is a bit of a science but can anyone give me a general range to stay between? i just don't want to put it too high or too low and burn out my atty in a matter of minutes. thanks for any help guys! again I'm vaping a 2.1 ohm atty between 4 and 4.5 volts.
