What Does Voltage Mean on a Vape?

Vaping has exploded in popularity over the last decade, with millions of people using e-cigarettes and Crystal Bar vape pens to quit smoking traditional cigarettes. But if you're new to vaping, all the technical jargon can be confusing. One term you'll frequently see is "voltage" - but what does voltage mean on a vape?? This comprehensive guide will explain voltage as it relates to vapes and how it impacts your vaping experience.

Understanding Electrical Voltage Basics

Before we dive into voltage specifically for vaping, let’s do a quick Electrical Voltage 101. Voltage is a measure of the "electrical pressure" that pushes electricity through a circuit. It’s measured in volts and represented by the letter "V". The higher the voltage, the stronger the electrical force.

For example, a standard AA battery has 1.5V, while a 9V battery (the rectangular ones you probably remember from science class) has, you guessed it, 9V. When it comes to vaping, voltage levels typically range from 3V to 6V.

How Voltage Works in Vapes

So how does this apply to vaping? Well, vapes work by heating a metal coil in order to vaporize e-liquid (aka vape juice). The voltage from the battery is what provides the power to heat that coil.

The amount of voltage impacts both the wattage (heating power) as well as the temperature of the coil. Higher voltage = a hotter, more intense vape. Lower voltage = a cooler, less vaporous hit.

Variable Voltage vs. Fixed Voltage

There are two main types of voltage you’ll see when shopping for vapes:

Variable Voltage

As the name suggests, these devices allow you to adjust the voltage level manually, usually within a range like 3V to 6V. This gives you control over the intensity of your vape. Generally, the higher the voltage, the hotter and harsher the vapor. Lower voltage provides a cooler, smoother hit.

Being able to play with the voltage lets you tweak your vape to find your ideal settings. Variable voltage (VV) devices also let you match the voltage to the specific resistance (measured in ohms) of your atomizer coil. We’ll get into that more in a bit.

Fixed Voltage

In fixed voltage devices, the voltage is preset and cannot be adjusted by the user. Some vape pens often have a fixed 3.6V output, for example, the SKE Strip Bar and SKE Icon Bar. This makes operation easy, especially for newer vapers. But the drawback is you have less customization of your vape intensity.

How Does Voltage Affect Vape?

how does voltage affect vape The voltage level ultimately determines the power output as well as the heat of the coil inside your vape. This has a direct impact on your vaping experience:

Vapor Temperature

Higher voltage heats up your vaping coil more, producing hotter vapor. This can sometimes be harsh on the throat if it's too warm. Lower voltages around 3V create a cooler vapor that many vapers find smoother.  

Vapor Production

More voltage = more vapor, generally speaking. Higher voltage powers a hotter coil, vaporizing your e-liquid faster and giving those dense, billowing clouds many vapers love. Just beware higher voltages drain your battery quicker.

Throat Hit

This is the intensity and “punch” you feel when inhaling vapor into your throat and lungs. Voltage plays a big role here. Higher voltage packs a more intense throat hit, which can feel harsh and irritating if too strong. Lower voltages provide a gentler throat hit.

Flavor

Some vapers claim high voltage intensifies flavor, but it usually comes at the expense of a harsher throat hit. So you have to find a nice balance for optimized flavor and smoothness. Typically medium voltages around 4V provide the best experience.

As you can see, the voltage level has a big impact on your vaping experience. Let’s look closer at wattage and resistance next, which also tie closely to voltage.

Voltage and Wattage Explained

Wattage (or watt output) and voltage are directly connected when it comes to vaping. Wattage determines how strongly your coil heats up and is measured in "watts" (abbreviated as W).

It's calculated by multiplying the voltage by the current (amperage):

Wattage = Voltage x Current

So for example, a vape with 4V and 5A would be:

Wattage = 4V x 5A = 20W

Adjustable-wattage mods let you directly control the wattage output, which changes the heating power going to your coil. More watts = more vapor.

Many variable voltage (VV) devices also allow you to adjust wattage. When you change the voltage on these, the wattage output will rise or fall accordingly. On regulated mods, you can adjust either voltage or wattage to control vapor production.

Electrical Resistance for Vaping

Now let's get into the third factor - electrical resistance, measured in ohms and represented by the Greek omega symbol (Ω).

Resistance determines how much opposition to electrical current there is in the vaping circuit. It stems from the metal alloy used in the heating coil and can vary widely.

Typical vape tanks have resistances ranging from 0.5 ohms to 3 ohms. Rebuildable dripping atomizers allow even lower resistances, even down to 0.15 ohms for extreme sub-ohm vaping.

Matching the voltage and wattage to the resistance is key for the best vape. Here’s a quick primer on resistance:

Lower resistance: Heats up faster and produces more vapor. Best for higher voltage/wattage. But drains the battery quicker.

Higher resistance: Requires less power to heat up. Better for lower voltage/wattage. Easier on batteries.

Sub-ohm: Coils under 1-ohm resistance. Allows higher power with more vapor. But needs stronger batteries and e-liquid with more VG.

Now let’s put voltage, wattage, and resistance together to see how they interact.

Finding Your Ideal Voltage Based on Resistance

On variable voltage/wattage mods, you can dial in the perfect settings for your particular atomizer coil by matching the voltage and wattage to the resistance.

As a general guideline:

• 1.0-1.5 ohm atomizers: Ideal around 3.3V to 4.2V, 10W to 15W
• 1.5-2.0 ohm atomizers: Best around 3.3V to 4.8V, 8W to 11W  
• Sub-ohm atomizers: Require higher power of 4.2V to 6V, 15W or more

The resistance limits for your particular device are usually stated in its specs or manual. Exceeding these can risk damaging your vape or battery.

For ultimate customization, use an ohms law calculator to dial in the perfect voltage for your coil’s resistance and your preferred vaping style.

Variable Voltage Safety Tips

While allowing more customization of your vaping experience, variable voltage devices do come with some safety considerations:

• Don’t exceed the voltage or resistance limits specified for your device. This can damage your vape or battery.
• Use the proper batteries specified by the manufacturer, such as high-drain 18650s for mods.
• Check battery voltage regularly as over-draining can damage batteries.
• Never vape with damaged batteries - replace them immediately.
• Keep batteries away from heat and enclosed spaces like pockets. Heat damages batteries.

Follow the manufacturer’s guidelines when using variable voltage mods and always put safety first!
