When thinking of Wattage, think light-bulbs... a 100W bulb is more powerful (brighter, hotter) than a 40W bulb... The same thing stands for vaping. More Wattage = more power, and subsequently more Amps are required of the battery to reach higher power.

More Watts does not necessarily mean more vapor. Sure, if the Wattage or Voltage is too low, vapor is diminished, but too much Wattage/Voltage will just cook the juice, giving you a horrible taste. Some juices will handle more power than others. More vapor is produced with higher VG content of the juice. 100% VG will give you the maximum potential for maximum vapor, and the hotter you can get it and the faster you can get it to the coil, the more vapor you get. This is why cloud-chasers are looking for maximum efficiency in their wicks, maximum air-flow, and the lowest Ohm coils possible, so they can produce extremely high temps via high Watts (which also means high Amps).

Voltage and Wattage are functions of Ohm's Law, and are two of the variables. Given that your coil's resistance is a set variable, you "set" either Voltage or Wattage to allow the device to determine the third. It is really a choice of the person to determine which method they prefer... Personally, I use slightly different Ohm coils across dozens of tanks, so I leave the Wattage setting as my "set variable" and let the device select the proper Voltage. This way I can maintain relatively the same flavor level across all my tanks. If you use the same resistance coils, you can use the Voltage setting, and the device will set the Wattage. Basically they both are the same side of the coin... more Voltage/Wattage = higher Amps, which results in more power/current.
