Variable Voltage vs. Variable Wattage
The new kid on the block when it comes to electronic cigarettes is the "third generation" personal vaporizer (PV), and the latest and best among these are the variable voltage and variable wattage varieties. These types of PVs are relatively complex to use and cost a little more, but they offer an enhanced flavor for some types of e-juices. Thus, they’re rather gaining in popularity, even if most vaping users begin with a less complicated device.
What determines the flavor of the vapor that comes out of your PV? The answer isn't only the e-juice itself, but also the heat and vapor levels that affect it. There are some flavors, like fruits and desserts, which taste just fine at low heat levels. Some others, however, like cappuccino and chocolate, require more kick to get a taste out of them that most users would call optimal.
Before we can define what variable voltage and variable wattage devices do, we must briefly review the basic facts of vaping the old way. Your atomizer has a resistance level that’s measured in ohms. Wattage is what determines how much heat your vaporizer’s cranking out. Voltage is the measurement of your battery’s potential energy. To up the wattage, you must either adjust the voltage or the battery or the ohms of the atomizer.
Standard electronic cigarettes will normally have a 3.7 volt battery, 1.5 to 3.0 ohms in the atomizer/heating element, and deliver about 5.5 watts of power to heat your juice. Even with some adjustments, these e-cigs can't get over nine watts. The new variable voltage/wattage PVs, however, typically have six-volt batteries, 3.0 ohms, and 12 watts. That makes a huge difference with some flavors, which explains why these devices are seeing their market share grow twice as fast as regular e-cigarettes.
Now, some devices are both variable voltage and wattage combined. Most, however, are either one or the other. What’s the difference then
Variable voltage PVs allow you to turn up the heat by setting your voltage to its max. Some models give you a range of from 3.0 to 3.7, others a range from 4.0 to 4.5. Variable wattage PVs, on the other hand, let you adjust the watts. You can range between 3 and 15 watts on many of these devices. This setting will adjust automatically to any changes in the ohms of resistance, allowing you to attach cartomizers with different ohm quantities without losing your "perfect setting."
Some PVs with variable voltage and/or wattage go a step further. They give you a menu and display that lets you monitor other things as well. For example, they may have an atomizer resistance checker, a battery-voltage checker, battery and vapor-production safety cut-offs, and puff counters. This whole set-up does make vaping a lot more complicated than just pushing a button and drawing a breath, but the many new features they offer are making them the preferred choice among many vaping users. Until "generation four" comes out, this is the most advanced electronic cigarette on the market.
We hope this article gives you a better understanding between the two.
