im currently using 5.5v which seems to be doing the trick... i just wondered if im missing a trick here.

Doesn't matter unless you change the coil to a different resistance. I like using watts but that's a personal preference. You only need to adjust one or the other, not both.

Select either the Voltage or Power setting at Menu Item #7. Power means VW and Voltage means VV. Both perform just as well but VW will automatically adjust the output when you change out atomizers or coils of different resistances. VW will also automatically compensate for coil aging. I prefer VW on the sigelei Zmax Telescopic V5. Another advantage to using VW (Power) on the sigelei is that all of your settings will be remembered after changing out a battery. I generally vape 6.5 to 7.0 watts.

Volt - unit of electrical potential or motive force, potential is required to send one ampere of current through one ohm of resistance.
Ohm- unit of resistance, one ohm is the resistance offered to the passage of one ampere when impelled by one volt.
Ampere- units of current, one ampere is the current which one volt can send through a resistance of one ohm.
Watt- unit of electrical energy or power, one watt is the product of one ampere and one volt - one ampere of current flowing under the force of one volt gives one watt of energy. I vape using wattage myself. Hope this helps you understand a bit better

thanks guys... Davep - what is RMS?

It's the measure of the actual voltage of a waveform based on it's Root Mean Square value. Since alternating or pulsing voltage varies constantly during the duty cycle, peaks positive, and may or may not cross zero and go negative, some method is needed to determine the actual value of its ability to perform work as compared to a direct current voltage.

True voltage of a waveform is the measurement of the voltage at all points in the wave and averaging them to arrive at a meaningful representation of the what it would be if it were a DC voltage. A sine wave will be different than a square wave or a triangle waveform. In ecig mods, the wave is usually a square wave pulse. Every so many milliseconds the value reaches the same level (amplitude), remains there for a time (duration) and then declines suddenly to zero and repeats. That's repeated over and over. The duty cycle (and the equivalent RMS voltage) can be changed by varying the pulse width (pulse width modulation), the frequency of the pulses (frequency modulation), or the amplitude of the pulses (amplitude modulation).

The idea is to aproximate the value that is equal to an equivalent DC voltage to compare the waveform to DC in terms of the amount of work it could do.

For a sine wave, it's .707 times the peak value of the wave. For a square wave, it's the peak value unless it's a pulse with time at zero between the pulses and no negative component, then you have to calculate the duty cycle (on/off/negative time). For a triangle waveform, it's .577 times peak.

It's much better understood with pictures and diagrams and formulas.
