Variable Voltage E-Cigarette Mods

We’ll be reviewing the best variable voltage e-cigarette mods that exist. Variable voltage is one of the many different aspects people get into with e-cigs to take it to the next level, usually after stepping up to things like tank systems, or ego-style batteries.

Connoisseurs like to do this with different blends of e-cig juice to get that perfect hit, and it has become a hobby-borderline-lifestyle for lots of vapers, and a really cool social tool, between the camaraderie and things like vapor bars popping up.

Before variable watt box and tube mods were all the rage, vape manufacturers developed variable watt mods. Until that point, most batteries were unregulated and many of them still are up to this day. They run at voltage too low for sub-ohm or even low-resistance coils.

Voltage starts at its highest but slowly dwindles to its lowest point before it becomes necessary to recharge. Eventually, variable volt e-cig mods came onto the market. First they were simple-looking items: not stylish, but functional. Now they come in numerous sizes and colors, even designer batteries. Moreover, most VW mods are also VV devices.

Unregulated batteries usually run at around 4.2V maximum volts. A basic regulated variable voltage e-cig goes by the name “Twist” or “Spinner.”

At the base you will find a knurled knob which vapers turn between 3.3 volts and 4.8 volts. They are not presented the option to change voltage by 0.1 increments but are given certain values to choose from. Spinner batteries are available in several sizes: from 650 mAh up to 1600 mAh.

They also come in a wide range of prices. Part of the cost issue comes down to the brand name. Expect to pay more for a brand marketed by a US company than a Chinese e cig, and expect to pay more in certain states than in others. Where competition is lax, price tags can be twice as much as the best going rate.


There is a variation on the “Twist” mod in the form of an Eleaf device known as an iJust. Available in two sizes (standard and mini), each one boasts a circular display at the very base, a USB port along one side for pass-through vaping, and a knob on the face for changing volts. This knob frames the firing button but is shaped so your finger easily gains traction to adjust for more or less voltage.

Eleaf also produces the iStick line: 10W, 20W, 30W, 50W mods which are variable by volts or watts.

30 watt isticks

While watts are often preferred, you aren’t playing with the terribly high values of a Sigelei 100W and the inherent dangers associated with that kind of power.

The lowest resistance for a 10W or 20W iStick is still no more than 1 ohm, so they offer a happy medium; a place to become accustomed to adjustable products.

Volcano LavaTube

This Hawaiian company adapted an earlier version of their advanced mod from a VV to VV/VW tube, but it’s still pretty much the same as before.

Use buttons to set volts or watts and watch values change on the screen.


Innokin makes a number of adjustable e-cigs such as the MVP, VV Express, and the CLK. Their iTaste CLK looks a lot like a regular e cig battery but bigger: 1280 mAh and adjustable from 3.5 volts to 5 volts.

The kit comes in black, silver, pink, or white and uses a slender transparent clearomizer that augments this mod’s elongated shape. Your atomizer’s resistance should not be lower than 1.2 ohms, but 2.1 ohms is recommended. The CLK features short circuit protection and the LED light changes color to tell you when the battery needs charging.

The iTaste MVP 30W is also a variable voltage option if you are confident about matching volts with resistance.

If not, it would be a good idea to find help from online charts which indicate the safe zones for volts and ohms, or you can switch back to watts and let the box select volts according to the resistance of your coil. The MVP 30W can be used as a power bank or a USB electronic cigarette when necessary.

Vision XFire VV Wooden Mod

This 1000-mAh battery is another spinner, but I mention it here because of its unique style. Most mods are made from stainless steel or anodized aluminum. A wood mod is sure to garner attention with its antique-style bronze cone. Adjust volts between 3.3 and 4.8.

Smok Rocket

Again, consumers have the choice: use this 18650 regulated mod in volt setting or watt setting. Your voltage range is 3.6 volts to 6 volts.

The stainless steel Rocket comes with a second top cap so you can use it as a 510 or eGo mod and attach any tank or clearomizer you like. A spring-loaded center pin allows whichever atomizer you choose to fit properly.

VaporFi Rocket

Florida’s VaporFi makes a variable volt Rocket e cig too.

A 1600-mAh starter kit costs about $120 for this attractive device and tank with adjustable airflow and 1.8-ohm coils. Turn the bottom knob for a change of volts. The battery’s style and shape is reminiscent of a Kanger EVOD where the button is set into the tube, not sticking out and interrupting a smooth feel.


This American mod is among the most popular US-made e-cig items on the market in its class and style.

Provari 3s

Its steel body and bright screen make it clean and user friendly. Switch between 3.3 volts and 6 volts as the atomizer’s resistance dictates, or choose/wrap coils at a certain resistance and set volts accordingly.

It is always a good idea to have an ohms meter handy to test your atomizer. Another meter (or one that performs both functions) will be needed to ensure your e-cig mod is properly calibrated and that the voltage reading you see on your screen is accurate.
