Regulated Box Mods: An Overview

Regulated Box Mods: An Overview

Earlier, we looked at the wide array of different devices vapers have at their disposal to power their e liquid delivery, ranging from simple cigalikes and eGo "pens" to advanced devices like variable-power mods and unregulated mechanical mods. Now, let's drill down a little more on what's evolved to be the most popular (and possibly most confusing) sector of the vape world – the regulated mod.

Regulated mods are ones where the user has the ability to adjust the power output of the device.  This was once measured in volts, but now the current most common measure of power is now watts. There's also joules – which we’ll get to another time.

First, a quick aside on Ohm's Law. This is most simply described as a means of measuring the power delivered to a device – the more volts you apply to your coil, or the lower resistance in ohm of your coil, the higher the wattage you'll be vaping at.

Think of volts as a measure of power you put into your device, and watts as the measure of what comes out. In the olden days (think 2013), vapers would measure the power they were applying to their device in volts, divide by the resistance of their coil in ohms to arrive at the amperage draw, then multiply the amps by the volts to determine how many watts they'd be vaping at.

Example: a freshly charged vaping battery typically provides 4.2 volts of power. If you're using a 0.5 ohm resistance coil, you're drawing 8.4 amps from that battery, and vaping at 35.28 watts.

4.2v / 0.5 ohm = 8.4a    8.4a x 4.2v = 35.28w

Sound confusing? For those of us without a mathematical background it is! That's why the computer chips in modern devices were designed to measure battery output and coil resistance, then do the math for us and arrive at the final wattage.

Aside from saving the mathematical hassle of vaping in volts, variable wattage devices function as a "set it and forget it" solution to vaping. Once you decide your favorite liquid vapes best for you at 25 watts, it doesn't matter whether you pop in a 0.5 ohm coil or a 1.2 ohm coil – your device will do the math for you and deliver the 25 watts you want to taste.

Because of this, very few modern devices use variable voltage – most that do are eGo types with an adjustment dial at the bottom (colloquially known as "twists" or "spinners"). Here, you'll find we specialize in variable wattage for power regulation.

Still, the choices in this department vary wildly. Options like the long-popular iTaste VV 4.0 (which does both variable voltage as the name implies as well as adjust wattage) offer the compact size of an eGo with features of a more advanced mod. It's limited, however, to just 15 watts – these devices are best paired with first-generation clearomizers like the Kanger Protank and Aspire Nautilus. Other, more advanced options in the iTaste line offer greater battery life and different styling options with similar performance.


But the next frontier of vaping is already upon us in the form of temperature control (TC), an entirely different way to control your vape experience. Using custom-built (and increasingly commercially available) coils made from materials like nickel and titanium that have a lower overall resistance that changes as the wire heats up, these mods can prevent the wire from getting too hot and burning the wicking material, thus avoiding the dreaded "dry hit." In this sense, "temperature limiting" might be the more appropriate description of what these TC devices actually do.

The full functionality of TC is something best discussed in its own post later on, but for now keep in mind that these devices are also capable of firing more traditional devices in regular wattage modes, making them an ideal choice even if you're not ready to explore temperature control yet but want to leave room for growth later on.
