Unregulated vs. regulated mods: Introduction

A common question when learning about different vape mods is “what is the difference between a regulated and an unregulated mod?” The first thing to know is that most vape mods on the market are regulated. They are the most popular choice for vapers from beginners to veterans. But there’s obviously much more to it than that.

For instance, go into a vape shop and you will eventually find a vaper, many times and employee, vaping with an unregulated mod. What gives? You may be wondering, why would anyone use an unregulated mod? Or maybe you are just trying to determine which mod is the safest — an unregulated mod or a regulated mod?

We will discuss the basic differences between these devices for those that are somewhat new to all this. And in case you are wondering, no advanced knowledge of electronics will be needed to understand this post. Future posts will go into more technical detail, but this for those that want to get the basics and move on with their day.

What is an unregulated mod?

A vape device that supplies raw battery battery power to an atomizer with no electronic circuitry, power adjustments or electronic safety features

Coming in the form of metal tubes or boxes made from wood to metal or plastic, an unregulated mod is the simplest of all vape mods in terms of functionality. Housing one or multiple batteries, a press of the button will complete the circuit and send raw battery power to the installed atomizer and coil.

Although simple in functionality, unregulated mods are deemed “advanced devices” because they will power any atomizer & coil regardless of the coil’s resistance, the type of wire, or even if the atomizer has a short (not good!). But they also allow the knowledgeable hobbyist freedom to create a wide range of vaping experiences from subtle to the extreme.

Types of unregulated mods

Mechanical mods (tube): Mechanical tube mods first hit the market in 2008 with the Screwdriver by Trog. It took a few years, but mechanical mods became highly sought-after. Generally in single-battery set-up housing an 18650 (or 18350, 18490, or 26650), and in a variety of metals, like stainless steel to copper to brass, these were the ideal device for hobbyists that eventually helped DIY coils (“building”) and cloud blowing become a thing.

Squonk Boxes: Started in ’09 with the JuiceBox, and then popularized by Reosmods, squonk mods are (mostly) unregulated box mods with either a single battery or battery bank with an on-board bottle of ejuice. That bottle is squeezed (or squonked) through a small window to supply juice upward into the atomizer. These devices helped make dripping more like using a tank.

Series mods: An advanced mod like the Wismec Noisy Cricket (v1) that uses more than one battery, most times side-by-side. Based on how the batteries are “wired” together (see image in gallery), the voltage of each cell is added together (ex. 3.7V + 3.7V = 7.4V) resulting in twice the voltage. But, the max current and battery life is a single battery. In that example, it’s twice the voltage of a single battery, but with the battery life and load capabilities of one battery.

Parallel mods: In a parallel mod, no matter the number of cells used, the voltage will remain that of one battery unlike a series mod (ex. 3.7V + 3.7V = 3.7V). In a parallel configuration, the batteries evenly share the load of the coil’s resistance. However, the battery life (mAh) and maximum current (amps) will be doubled, thus allowing very low coil resistance while minimizing the strain on any one cell.


  • Zero restriction on the resistance of the coil used (no matter how unsafe the resistance)
  • No electronics to break or bug out
  • Can (most of the time) be fixed easily with a simple trip to the hardware store
  • No instruction manual or complicated menu system to navigate
  • Simplicity of design
  • Virtually unlimited power (depending on number of batteries and atomizer)


  • They can be very dangerous if the user is inexperienced
  • They will accept any resistance atomizer even if it’s in the battery’s “red zone”
  • Not ideal for the beginner
  • The vape diminishes as the battery power decreases

What is a regulated mod?

Any of various vaping devices that include one or more safeguards or advanced features (like power adjustments) from electronic circuitry.

There are two main types of regulated devices, adjustable power and fixed voltage. Adjustable power devices have a chipset that allows for controlled power to the atomizer to remain constant, even if above or below the batteries actual voltage (ex. 3.7V battery putting out 5V). After the battery drops below the mod’s battery minimum voltage limit, the device will no longer run and batts will need to be charged, but the vape will remain constant until that point.

Fixed-voltage may refer to a cigalike (cigarette-looking ecigs), a pod vape like the JUUL, or something like a standard eGo (pen-style) battery which uses fixed-voltage battery power from built-in batteries (all mods with built-in batteries are regulated). Fixed voltage devices often times have limits to the resistance of the atomizer’s coil that they will accept which makes them ideal for rank beginners. Similar to an unregulated device, the vape with a fixed-voltage device will diminish with the battery’s loss of power.

Types of regulated mods

Fixed voltage: Fixed voltage devices were the very first ecigs. They are the go-to choice for beginners since they require no tinkering and little if any instructions. These devices typically use a single button or a vacuum switch that senses changes in pressure as you draw. They still dominate the market due to ease of use. Cigalikes (both rechargeable and disposable), standard eGo, e-cigars, AIOs, JUUL ecig, etc are all fixed voltage.

Variable Voltage (VV): Introduced in 2010 (BuzzPro and the Provari), these devices were revolutionary! Using microprocessors like buck-boost converters, these mods allowed vapers to exceed or go below a battery’s output voltage, thus intensifying or mellowing the vape. VV devices like eGo spinners and the Provari are still widely used, but most variable wattage devices do the same, and more.

Variable Wattage (VW)
: First on the scene in January of 2011 with the Darwin by Evolv (and a year later with the SvoeMesto Semovar). These devices really propelled modern vaping to what it is now. In basic terms, your desired power setting can be constant if you like, even after charging an atomizers resistance, something that variable voltage mods can’t do.

Temperature Control (TC): Released in 2014 by (Evolv), the originator of the variable wattage device, temperature control (TC) mods allow the user to set heat limitations to their to specific types of coils, something VV or VW can’t do. But TC mods are not their own kind of device per se, but a further development for many VW mods. TC mods are also VW mods.


  • Various protections and safeguards to protect the user
  • Does most the math for you
  • Detailed instruction manuals are standard with these devices
  • Ideal for beginners all the way to veterans
  • Countless options (mods) to choose from
  • Available in simple “stealth” devices all the way to cloud-chucking mods with loads of power


  • Electronic protections can make the beginner too lax about battery safety
  • Every regulated mod has restrictions on the load/resistance of coils they will accept (not every coil will work)
  • Sometimes quite complicated to learn (for the advanced regulated mods)

Which mod is right for you?

If you want to go with unregulated mods, first ask yourself: do I have a decent understanding with ohms law, battery chemistry/safety, and the appropriate or inappropriate atomizers to use. If you answered no to any of those questions…

It is strongly recommended that you stick to regulated mods until you are comfortable with those matters. There are countless options for regulated mods with a wide range of capabilities. Most have roughly the same kinds of basic battery safety features and they can keep most user-errors to nothing more than a warning message on a digital display.
