Open-End Systems vs Closed-End Systems – Which One is Better?

Open-end systems and closed-end systems are the terminologies used to define the two main kinds
of e-cigarettes. The main difference between them is the e-liquid delivery to the heating mechanism.
For instance, you need to refill your open-end device tank manually with an e-liquid that reaches the
heating unit, while the closed-end device comes in filled tanks with an already dipped heating unit in
its e-juice.

What is Open-End System Vapor?

The open pod e-cig device has a removable mouthpiece, and a tank to hold the juice. The word
“open” reflects refillable pods.
The average shelf life of a coil in an open pod device is 1-2 weeks. It depends on the e-liquids used in
it, the usage amount of e-liquid, and device set quality.
Whether you are looking to target flavor or nicotine strength, LIX, a top vaping brand in North
America, offers products that meet the highest quality standard with a wide range of vaping e-liquid
choices. LIX e-liquids are formulated with the purest and cleanest nicotine to add the best freebase
e-liquid flavor blends into your open system device.

What is Closed-End System Vapor?

This system contains a mouthpiece built into the closed system e-cig cartridge along with a smaller
tank-like juice cartridge. This e-cartridge is screwed onto its rechargeable battery for heating the
One closed system device saves you the cost of one pack of cigarettes. In this sense moving to
closed-end vaping may bring remarkable savings.

Pros and Cons of Vaping Devices

Pros of Open-End Systems

An open system device gives you the freedom of choosing e-liquids with your favorite flavor and
even your desired nicotine strength.
They usually come in the form of regular vaporizer sizes like vape pens.
They are portable.
Open-End devices like sub-ohm and mod, are reusable and refillable.
They have a strong and rechargeable battery to deliver you a long-time carrying vape experience.
You can produce bigger and denser clouds through an open vape system.

Cons of Open-End Systems

The open system device requires you to press a button for activating the heating element.
They have a tank that you fill manually with your e-juice once you run out.
Open-end e-cig device requires manual cleaning and maintenance to keep them working properly.
They may have big and unmanageable sizes.
While buying an open pod mod device for yourself, you must consider the wicks and battery to be
perfect. For example, it would be a mistake to buy a cheap open-end system device with a nonsuitable wattage battery. This kind of device would not be capable of heating your e-liquid properly
and you may end up experiencing a poor vaping sensation.
Your open system vapor can get out of order if you use non-suitable e-liquids. You must check
whether e-liquid will work well with higher VG content in the e-juice.
You have to carry your e-liquid bottle around you for refilling purposes if traveling for a longer time.

Pros of Closed-End Pod Systems

The disposable closed-system pods help the new users vape without carrying a large or complicated
device and an e-liquid to fill their pods.
The experienced vapers can keep a closed pod system backup device with them to tackle the
situations of battery drainage.
The closed system pod has a simple design with no hassle to clean or perform maintenance of a
closed system pod mod.
It has a rechargeable battery.
It does not require you to trigger a button to inhale your juice from the device and activate the
heating element.
The use of nicotine salts in your closed system device such as pod vapes gives you a more satisfying
nicotine vape than a regular freebase nicotine e-juice.

Cons of Closed-End Pod Systems

To make a closed-end system device work, you need to insert a pre-filled cartridge or pod into your
If you are not careful about keeping your stuff with you, you can lose your pod easily.
Closed system vapors can also be costly as you can’t refill them until you spend money on buying
another new vape pen.
A closed system vapor can be expensive for heavy nicotine users as they must buy more pods if they
find themselves running out of a single pod in a day,
Because you must dispose of your disposable empty pods, your closed system device waste can be
superfluous to community waste.
The closed system pod comes with a basic variety of tastes like sweet to fruity, tobacco, smoke, and
menthol e-liquids. Users, therefore, have a limited range to enjoy different flavors.
Closed-End devices come in ready-to-use tanks with the prefilled nicotine-strength liquid and don’t
give you nicotine level choices. You therefore can’t change them according to your desire like in an
open-end system device. If you decide to buy a closed-End pod device, you must consider nicotine
strength before you do.

Did You Find the Answer to Choosing Your Perfect Vaping Device?

Closed-end pod systems and open-end pod systems both have their places in the market of vape
devices. If you need a more streamlined experience, closed pod systems will suit you best. A closed
system device is also a perfect choice for smokers who need to switch into the world of vaping
easily. Closed-system pod sets you free from cleaning the device.
While open-end system e-cigarettes are often the choice for beginners and mouth-to-lung vapers,
experienced vapers also keep an open system device as their backup in a more compact option.
You must know your vaping goals and consider the pros and cons of both kinds of vaping devices and
e-liquids to decide. You can also consult LIX’s customer service team for the best-suited vaping


Explained: every vaping-related term that’s made you pause and go, “what?”
The vaping industry was born out of a growing desire among our consumers to have
better choices. When more choices are provided, so grows the language that describes
those choices too. For many, vaping is an intriguing topic, yet it can leave the average
individual feeling stumped or overwhelmed due to technical terminology and
colloquialisms. We invite you to browse our A-Z Glossary of Vaping – a comprehensive
guide so you can truly understand your options. And if you have any questions please

All Day Vape (ADV): An e-liquid that can stand the test of time, something you can enjoy all day
without being overwhelmed.
Analog: Traditional cigarettes, cigars, and pipes. E-cigarettes are electronic and digital and thus
the older cigarettes, cigars, and pipes are considered analog.
Airflow: The amount of air that passes through an atomizer or tank. Higher/looser airflow results
in more vapor, while lower/tighter airflow results in less vapor but more intense flavor.
Amps: Short for amperage, this is the flow of energy across/along an electrical circuit. Batteries
with higher amps can better handle atomizers with lower resistances without overheating.
Atomizer: This is the (replaceable) part of an e-cigarette, that contains a wick (usually cotton)
and the coil housed together. The wick feeds the e-liquid into the coil. The coil when heated turns
the e-liquid into vapor.
Battery: This may refer to one of two things:
1.) The core part of an e-cigarette, the term usually refers to vape pens and cig-a-likes like
MYLÉ, STLTH, KI, SMOK Nord, SMOK Novo, etc. There are two types, manual and automatic.
Automatic batteries are switched on by inhaling, while manual batteries require the user to press
a button found on the side.
2.) For users of Mods, this refers to Li-ion batteries used to power their devices.
Cig-A-Like: This is a slang term for an e-cigarette that looks like a traditional cigarette.
Cloud Chasing: Trying to blow the largest and densest vapor from an e-cigarette.
Coil: This is the metal wire that is used to turn the e-liquid into vapor by heating up. Coils are
most commonly made with kanthal, stainless steel, or nichrome.
Coils can be classified into two categories:
● Sub-Ohm (<1 Ohm) – Used for high vapor production and intense flavor. ● Above-Ohm (>1 Ohm)- Used for a higher concentration of nicotine, low vapor production
and emulation of smoking.
Disposable: An e-cigarette that is used until it’s out of e-liquid, then discarded completely.
Dry Hit: When a vaping device is used without e-liquid (usually accidentally), it burns the wick,
resulting in an extremely unpleasant experience.
Deck: The part of the atomizer in which the +ve and -ve posts are found. Deck is an exclusive
term to rebuildable atomizers, pre-made atomizers for Tanks do not have a deck.
Draw: The act of inhaling vapor from the e-cigarette mouthpiece into your mouth.
Drip (Dripping): Refilling an atomizer via drops of e-liquid straight onto the coil of an atomizer,
this is exclusive to rebuildable atomizers.
Direct to Lung: Inhaling straight to the lungs, without holding it in the mouth first. Direct to Lung
e-cigarettes are usually designed for an enhanced experience in flavor and quantity of vapor,
only to be used with lower concentrations of nicotine.
E-cig: Shorthand for an e-cigarette (electronic cigarette)
E-Cigarette: The term used to describe any alternative electronic device that satisfies the
nicotine craving of a person.
E-liquid (E-Juice/Juice): The solution that is vaporized to create vapor. It is usually made from
propylene glycol (PG), vegetable glycerine (VG), flavoring, and nicotine (there are also some
without nicotine). E-liquid comes in two formats, Freebase & Salt Nicotine.
Flooding: Filling up too much e-liquid in the atomizer. Flooding is the root cause of the gurgling
noise that an e-cigarette makes.
Leaking: When e-liquid is seeping out of the e-cigarette. Leaking can be caused by a variety of
factors, including but not limited to, overfilling an e-cigarette, improper storage, improper use,
damage to the device, or changes in air pressure.
Lithium-Ion Battery: The power source for a rechargeable e-cigarette. The Lithium-Ion is the
most commonly used type of battery.
mg: This is the indication of the amount of nicotine in an e-liquid per milliliter. 3mg is 3 milligrams
of nicotine per milliliter, or 0.3% nicotine.
Mod: The shortened version of “modification.” A type of e-cigarette you can modify by adding on
your own choice of batteries, tanks, atomizers, etc., often with the goal of improving the
performance of the device.
Mouth to Lung: Inhaling into the mouth, before transferring into the lungs. Mouth to Lung
e-cigarettes are designed to emulate smoking and are designed for use with higher
concentrations of nicotine.
Nicotine: Nicotine is an addictive substance found in cigarettes and e-liquids. E-liquids have
varying amounts of nicotine, ranging from 0% to 5.9%. Users can choose the amount of nicotine
in their e-liquid based on their preference.
Ohm: A measurement of electrical resistance. The resistance of a coil dictates the amount of
time it takes to heat up the coil and the amount of electrical current that can pass through it.
Organic Cotton: A type of wick used in atomizers, organic cotton burns quick but offers cleaner,
more intense flavor.
Pods: A pod is a chamber (usually clear) with an atomizer inside, this atomizer cannot be
changed or replaced. A pod can either come pre-filled with e-liquid or be a blank pod that can be
Pod System: E-cigarettes that use replaceable pods, with built in atomizers.
Pod Systems can be classified in two categories:
● Open Pod System: Refillable pods that can be used multiple times.
● Closed Pod System: Pre-filled pods that can only be used once before they have to be
PG (Propylene Glycol): One of the primary ingredients in e-liquid. This fluid has no odor and no
color and is less viscous (thick) than VG, and is used as a binding agent for the nicotine and
flavoring used in the e-liquid. It is also used to provide a ‘throat hit’, which some users claim is
similar to the sensation experienced when smoking tobacco
Rebuildables: This refers to atomizers/tanks that let users build their own coils and install their
choice of wick. Primarily used by advanced users, rebuildables allow users to modify their setups
to achieve their preferred vapes.
Rebuildables are classified into three categories:
RDA – Rebuildable Dripping Atomizer, a type of rebuildable where there is no reservoir
for holding e-liquid. E-liquid has to be dripped directly onto the wick and it needs to be
refreshed continually after 8-10 draws.
RDTA – Rebuildable Dripping Tank Atomizer, a type of rebuildable where there is a
reservoir which is not connected to the wick. When the wick dries out the RDTA needs to
be aligned so that the e-liquid can drip onto the wick.
RTA – Rebuildable Tank Atomizer, a type of rebuildable with a reservoir connected to the
tank. Functions like a rehgular tank while still offering the advantage of modifying the
Starter Kit: A package that usually has everything one needs to start vaping.
Most starter kits include, an e-cigarette, a tank, an atomizer and a charging cable or if it is a pod
system it may include, a battery, pre-filled pods/blank pods and a charging cable.
Tank: A cylindrical reservoir that holds the e-liquid and feeds it to the atomizer.
Throat Hit: The feeling of vapor hitting the throat when a user inhales the vapor from an
Vape: The act of using an e-cigarette. “I’m going to vape this ‘Quad Berry’ e-liquid.”
Vaper: A person who vapes.
Voltage: Refers to the electrical potential of the battery.
VG (Vegetable Glycerin): One of the primary ingredients in e-liquid. This fluid has a faint sweet
odor, no color and a faint sweet taste. It is highly viscous, and is used for its ability to create a
dense vapor.
Variable Wattage: An e-cigarette that has functionality to control the Wattage.
Wattage: The amount of heat that passes through the coil to turn e-liquid into vapor.
Wick: The wick is a filament (commonly made of cotton, fiberglass or ceramic) which feeds the
e-liquid to the coil
