Variable Voltage is different from regulated and mech mods. You can dial your voltage up, for more vapor, flavor, etc. Best to start low and adjust in small increments to taste or until it "feels right." (Or generally set it x2 your ohmage. 2.2ohms @ 4.1 volts, etc)

Variable Wattage gives you consistent power. You set it at whatever level you want, you leave it, you probably forget. It does not suffer from voltage drift - wherein your performance will drastically decrease as your battery drains its power. It will automatically adjust your voltage based on the ohm of your coil, and continue powering said coil at whatever level you leave it.

You don't absolutely NEED either. A coil, on a 3.7v eGO, at whatever ohms gives you the best vape (AKA your sweet spot) will certainly do the trick. That being said, the ability to dial up or dial down depending on what setup you're using, what juice, etc... can be a very handy tool indeed.

It helps to mitigate a lot of problems that can occur by giving you a more tailor customed vape experience.

    What VW has going for it is we always think in terms of the end result regardless of which we use anyway, and that end result is measured in watts. This makes VW a little more intuitive for many. The e-liquid really doesn't care what mathematical formula you choose to use so long as you supply the proper amount of power to it.

    With the Sigelei Zmax the user can run VV or VW anytime they choose. That is the case with most rigs that offer VW. They are actually VV/VW.

    I run on the power setting (watts) all of the time now. I use both 1.8 and 2.0 ohm cartos. With VV I must adjust the voltage every time I change carto resistance to get the same vapor quality and the same power (watts). With VW I simply set the desired power I want and the mod will automatically calculate how much voltage it needs to provide to the carto for the power I have selected regardless of the atomizer resistance. Whether I'm using VV or VW I still adjust either voltage or power (watts) up or down several times a day just to fit my mood at the time.

    Also, the Sigelei Zmax won't remember voltage settings (in VV) after a battery is changed. It will default to 3.0V as a safety feature. In power (VW) mode, the Sigelei will remember my power setting after battery changes. That's a big convenience.

    The same vapor quality is available from both VV and VW. VW is just more convenient and less fuss for many.

    Above post wrap it up pretty much.
    Should not make any difference in your mod,
    but if you can get a mod with both Vv and VW.......

    Only thing to add is with VV you may be clicking away to adjust your
    volts to match the ohms of your topper. With VW, set it for 8 watts,
    and change toppers/juice all day without having a "click fest".
    My Zmax v5 is set for 8 watts, and I can swap out PTII, Evod BCC, knock off clearos, all day without a whole lot of
    user input. Only time I may cahnge it is with the last batch of juice......40/60 blend, a little thicker.

    VW leaves you at the hands of your ohmmeter and PV's processor to adjust voltage accordingly. Sometimes ohmmeters screw up, and they can also just be permanently off.

    I use VW on my MVP. I have a 5 Volt or 11 Watt limit, with a 3 amp cutoff/limit. Since I use 3 ohm cartomizers, I can be at about 5.2 Volts with it set to 9 Watts. If I used a low resistance and wanted higher wattages than 11, I can more than likely reach that with the voltage. 11 Watts with a 1.5 Ohm coil is 4.06 Volts.. I'm sure I wouldn't be going much higher than that, but I have the option to, if I wanted. I couldn't max out my voltage at 5 Volts with that same 1.5 Ohm resistor. That would equal about 3.3 Amps, 0.3 Amps over the 3 Amp limit on the MVP.

    I always thought VW was for inexperienced vapors who don't yet know the performance of their coils and what power each particular juice vapes best at.
    Not really very good advice. With anything you should learn who to use it properly not just hope your doing it ok. This can lead to costly mistakes and frustrating experiences if you dont.

    VV vs VW is just preference. The end result is X amount of DC current going to the coil. There are well made VV and VW devices as well as poorly made ones. The Quality of the mod and the electronics is what give you better performance.

    Here we go again

    In fact this thread has happened so so so many times in the last 2 month's

    All I can do is:pop:

    at this point


    Well, don't forget it is common for questions like this to get asked several times a week on this forum - the main reason being new vapers are coming and going all the time.

    It is less common for people new to use the search function, then people who have been here a while - and it takes about the same time to make a post asking a common question then searching - which is why you will always see questions like these repeated.
