Love my EVOD but what is the deal with variable voltage?

I started out with an Ego-T Upgrade, which is kind of a variable voltage - it had two levels, Regulated (which output 3.3V) and Unregulated (which put out a higher amount, depending on how charged the battery was, of up to 4.5v). You can switch back and forth using a 5-click--hold--5 click pattern on the button.

I noticed that some flavors tasted different (better) on the higher voltage. I also got a stronger hit, which was helpful when I felt I needed nicotine more quickly, or when drinking. (haha.)

I since upgraded to a true variable voltage (the Vision Spinner), which can be infinitely adjusted from 3.3 to 4.8V, and have noticed an incredible difference in the vapor production at the high end, and the difference in flavor from one voltage to another. For example, a rocky-road flavor tastes good at 3.3, amazing at 4.0, but kind of burnt at 4.8. (This is using a 2.5ohm coil in a Kanger MT3S.)

Note that using a coil with a different resistance (measured in ohms) will affect the flavor/hit/vapor production as well. The interaction between the output voltage of your e-cig and the resistance of your coil results in a wattage (Voltage2/Resistance = Watts). There's a chart floating around the internet that shows the actual computed wattage for various combinations of volts and ohms - you can see it at General Safe Vaping Power | Voltage | Resistance | Ohm Chart. The wattage is really the important number, and keeping it between 4 and 9 seems to be the ideal range for most juices.

So why variable voltage?
  • Adjust to different juices more easily, and find the sweet spot for any given one.
  • Adjust your vaping to your mood at the time.
  • Fine-tune your vaping experience based on the resistance of the coil in the cartomizer/atomizer you're using.

My first post, hope it's helpful!

I don't like big, bulky devices (that is why I found the evod appealing because it isnt that large). Are there any VV/VW at about the same form factor?

I am a huge fan of VW over VV. As has been pointed out already, both allow you to "fine tune" your vaping experience. However, VW adds in a bit more consistency if you are often changing tanks and flavors, as it adjusts the output voltage based on the coil. If you don't change coils often, then VV is probably just as useful for dialing in the best flavor/vapor combination for your personal tastes.

I use a innokin itaste vv3. Its a variable voltage/wattage with a usb passthrough and lcd screen. Still has the small form factor. I see a lot of friends going with ego twist, but after switching to usb passthrough batteries I dont want to go back to non passthroughs. They seem too troublesome, especially if you just have one setup like most beginners do.

variable voltage -- switch up the taste a bit for different vape. I dont fiddle with my wattage too much, but its higher than my fixed voltage batteries.
