Ohm's Law is E=I*R where E is voltage in volts (V), I is the current in amps (A), and R is the resistance in ohms (Ω). By extension, P=I*E, where P is the power in watts (W). mAh, or milliamp hours, is not pronounced "ma," and it is a rating of how long a source will supply a certain amperage for a certain amount of time (it is calculated by multiplying amperage and hours, hence mAh).
With that said, I have seen, time and time again, vapers and manufacturers using voltage and power interchangeably or using wattage as if it were an independent term. I currently use an EVOD battery (until I can pick up a VV mod) which is rated at 3.7V with 650mAh and a 1.8Ω coil. This means that my set up draws 2.06 amps, and puts out 7.61 watts of power; if it could, it would do this for about 12 minutes continuously. Alternatively, if I used a 2.5Ω coil it would put out about 5.5 watts and would go for about 20 minutes. That was all math... very simple math, at that.
If you're gonna geek out about these electronics, at least learn the terminology and use it [all] correctly. Some vapers don't even care to learn this stuff... even though they use it, whether they like it or not, every time they use electricity. I (like most of you) like to watch or read reviews before I go buying new toys; and whenever I hear or read somebody using all these terms incorrectly, I instantly stop trusting anything technical they have to say. Obviously, I can still value their opinions but I am forced to take any of their techno-babble with a grain of salt.
I've only just gotten off the New Members Board, but I figured that this would get better reception with the more veteran members. </rant>
