I have been on here for a week extensively, I have only seen this posted once. Im sure it is elsewhere plenty of places, but just thought i would draw some attention to it for my fellow newbies. This is an incredibly helpful chart outlining your volts, resistance and safe operating ranges. Very good starting point for vaping safely with the more advanced PVs.
