Allow me to face palm myself... Baditude from another forum answered this question. "With variable voltage mode (U = voltage), you figure out what the ohm rating of the coil you are using. Press both + and - buttons on the MVP2 simultaneously. The first numbers that come up is the coil resistance in ohms. A - 2.0 . (The next number will be the battery voltage.) Then do the Ohms Plus Two Formula. In your head, add the ohm and add the number "2". The sum will be the suggested voltage. 2 ohms + 2 = 4 volts. Adjust to your personal preference. In variable wattage mode (P = power mode), you set the power (from past experience and preference) to a certain wattage, say 7 watts. Then if you change tanks which may have a different coil resistance, the MVP's processor recognizes the change in resistance, makes the calculations and sets the ouput so that you are still applying 7 watts output to that coil. Which ever mode you last made a setting for, the MVP stays in that setting." ...Well, at least I didn't break math. RAV

Hi all, I'm brand new to vaping and have just burnt my first coil, pretty much immediately. So while I wait for new coils to turn up in the mail, I'm smoking a ciggie and pondering my folly. So you know (or will know) Ohms Law: E^2 = P x R Ohms law in mind; I am immediately confused by my variable voltage device (MVP 2.0). It can change volts(E) and watts(P) independently. But since my coil has a fixed resistance( R ), how can watts AND volts be variable simultaneously? pre-Thanks heaps for help on this. Rav
