The overall working principle of electronic atomized cigarette Pod system

In recent years, the e-cigarette industry has continued to innovate with a variety of new technologies and improved e-cigarette devices. Among these, the e-cigarette pod (Pod) system is one of the latest engineering feats that has received attention from everyone’s target consumer group. The way some of these systems work can be confusing to those who are new to Pod system e-cigarettes. Next, we’ll reveal all the details of how some of these systems work and explain the differences between closed and open Pod systems to help you determine if this newer style is right for you.


What is a Pod system?

A Pod system is a type of e-cigarette that uses a small container called a “Pod” instead of the tank and atomizer of traditional e-cigarette models. Essentially, they work the same way as atomizers and tanks, but they are more portable and discrete.

Compared to other e-cigarette products, the Pod system is relatively new. Little did we know that since Pod systems were introduced, they have created a niche market in the e-cigarette industry.

The vast majority of Pods have a small fluid capacity, usually around 1-2 ml, but there are many Pods that have a larger fluid capacity.

Pod system components are usually mounted on the top or bottom of the device and can be easily removed when the device runs out of fluid or when you want to change flavors.
Overall, the Pod system is more compact compared to other e-cigarette models, including the battery and fluid capacity. Considering the smaller size, some of these models also have a shorter battery life.
In such systems, automatic operation is usually used, where we only need to inhale to produce the atomization effect, but many may also offer manual button operation, similar to a traditional e-cigarette regulator.
When these new systems were first introduced, they were relatively simple in design. Unbeknownst to them, as time went on, more and more advanced devices appeared on the market that offered more features while retaining the compactness and ease of use of the Pod system.
How does the Pod system work?
E-cigarettes rely on two basic components to work: the cartridge and the battery. When we activate the vaporizer by inhaling, these two components communicate with each other and work in tandem to deliver vapor to your mouth. The following are the roles played by each component:
Cartridges are known by a variety of names. Some call them Pods, others call them top caps, atomizers, or just plain old cartridges.
The cartridge is the part of the e-cigarette that sits on top of the system and contains the e-liquid and nicotine used to produce the vapor. The vast majority of e-cigarettes already come pre-filled with e-liquid, but you can still find some that offer fillable systems so that you can use your own bottle of e-liquid to fill the cartridge as needed.
The other component inside the cartridge is called the atomizer and consists of a small metal tube. When we inhale the e-cigarette from the system, the atomizer turns the e-liquid into vapor. This sends a signal to the e-cigarette, sending energy to the atomizer to heat and vaporize the e-cigarette liquid. (Note that some people will split these components into two separate parts: the cartridge on top and the atomizer on the bottom.)

Batteries are theoretically much simpler than cartridges. Batteries used for such systems are usually long, thin and smooth. The battery’s job is to determine if you are smoking an e-cigarette so that it knows from when to use the power and from when to store it.
Batteries can do this in two different ways, creating two types of batteries:
Automatic batteries: These batteries do not have any buttons on them. Simply inhale into the mouthpiece and the e-cigarette product will energize the battery.
Manual batteries: Manual batteries have a button that you press to ignite the e-cigarette and make the device work.
The Pod battery is a simple device that can be charged using most USB chargers or wireless charging racks.
The two components work together and together form the mechanism by which the Pod system works. When the user places their lips on the mouthpiece and begins to inhale (or presses the ignition button on the manual battery), the system sends a signal to the battery that delivers electrical energy to the cartridge, activating the atomizer, which heats and converts the e-liquid into vapor for the user to inhale.
Advantages and disadvantages of Pod system e-cigarette products
Many users of e-cigarette products choose Pod System e-cigarette products over other options because this type of e-cigarette product has some important advantages:
Small and portable: Pod System e-cigarette products are small and slim enough to easily fit in a pocket, carry around, and are designed so that they can be well hidden in discrete locations to avoid the embarrassment of sticking out of a pocket.
Easy to use: Pod System e-cigarette products are designed to be intuitive to use, simply inhale the vapor, and replacing the pod is the easiest part of the closed pod system, making it less prone to error.
Affordable: Once a battery is purchased, you only need to purchase a new one when it runs out, saving money by not requiring additional parts or maintenance.
Discrete: Pod System e-cigarette products are more compact compared to other large cartridge e-cigarette products and provide a gentle vapor flow that is not easily noticed by those around them, protecting the user’s privacy.
More Satisfying: Pod System e-cigarette products provide a satisfying e-cigarette product experience by using a high-intensity liquid and an intuitive inhalation process that satisfies the user’s oral and throat needs.
Unbeknownst to users, Pod System e-cigarette products are not the right choice for every user, and some basic complaints include
Smaller batteries: Pod system e-cigarette products often have smaller batteries, resulting in shorter battery life. While most batteries are only used while vaping, the power can run out quickly and need to be recharged frequently.
Higher nicotine content: Pod system e-cigarette products work better with higher nicotine content e-liquids, but most high nicotine liquids need to be purchased from outside Europe due to European TPD restrictions on nicotine.
Smaller clouds: If users like to create a lot of dense clouds, they may not get the same satisfaction with Pod System e-cigarette products because of their smaller cloud size.
More limited flavor selection: The closed Pod system means that users can only choose from disposable Pods offered by the manufacturer and have a more limited flavor selection, but high quality closed Pods can now be found online to choose from.

Types of Pod System E-Cigarettes

There are two main types of e-cigarette pods to choose from: closed systems and open systems. The main difference between them is how the e-cigarette liquid is delivered to the rest of the heating device. Pods with open systems can be opened, filled and reused, while pods with closed systems cannot be filled and need to be disposed of once the e-liquid is used up (called disposable cartridges).

Open system e-cigarette pods are easy to fill because they usually have an easy-to-open top and an opening large enough to add more e-liquid without getting it everywhere. The main advantage of this type of e-cigarette system is the ability to customize it to your personal taste preferences, as you can use many different e-liquids, offering almost endless options that are not limited to pre-filled pods.

In addition, some users have noticed that the smoking experience is smoother and produces larger and thicker vapor clouds when using e-cigarette pods with the Open System. However, open systems also require more work, such as regularly charging and replacing pods and coils, and can be larger and less portable, which may take some getting used to for beginners.

Closed system e-cigarette pods are similar to cartomizers and use pre-filled e-cigarette liquid cartridges. Once a cartridge runs out of e-liquid, the user simply discards it and replaces it with a new cartridge, making the refill and replacement process easy and convenient. Closed system e-cigarette pods are less demanding in terms of maintenance, as users only need to purchase new pre-filled cartridges and do not need to replace coils or maintain tanks.

However, there are some drawbacks to the closed system, such as complaints from some users about weak suction or the fact that the e-liquid inside the cartridge may produce what is called “spitback” during use, where the e-liquid bounces off the coil and into the user’s mouth without vaporizing properly.

Whether you are attracted to e-cigarettes because of the newer models, or are an e-cigarette veteran interested in trying something new, the pod system (whether open or closed) offers a unique, convenient, and user-friendly e-cigarette experience that is very compelling.


After learning more about how e-cigarettes work and the pros and cons of closed and open systems, you should now have a good idea of whether or not to try your next Pod system.

Simply put, if you want an intuitive, user-friendly, and affordable e-cigarette, then you should consider the Pod systems available on the market today. But if you are more concerned about custom blended e-cigarette oils, higher nicotine levels, and producing large clouds of vapor, then you may prefer to stick with your Box Mod or e-cigarette pen.
