Basic Components of a Vape Device
Every vape device has several essential parts, and knowing what each does is critical for maintenance and usage. Here’s what you need to know about the core components.
Atomizer
This is the part of your vape that heats the e-liquid and turns it into vapor. Atomizers contain coils and wicks and are sometimes referred to interchangeably with the term “coil.” There are different types of atomizers such as rebuildable atomizers (RBA), rebuildable dripping atomizers (RDA), and sub-ohm tanks.
Coil
A coil is a wire or mesh wound in a spiral shape that heats up when electricity passes through it. It’s responsible for vaporizing the e-liquid absorbed by the wick. Coils have a lifespan and need to be replaced every few days to weeks depending on usage.
Mod
The mod is the main body of a vape device that houses the battery. It can be either regulated (with safety features and wattage control) or unregulated (mechanical mods). Mods often determine how customizable your vape experience is.
Tank
A tank holds your e-liquid and includes the coil and chimney. Most modern tanks are transparent and allow users to see how much e-liquid is left. Tanks vary in size, airflow control, and coil compatibility.
Pod
Pods are used in pod systems and are usually simpler than tanks. Some pods are refillable, while others are pre-filled and disposable. Pod systems are excellent for beginners due to their ease of use and portability.
Vaping Styles Explained
The way you inhale from your vape device significantly impacts your experience. These terms describe different inhalation methods and are often used to guide device and e-liquid selection.
MTL (Mouth-To-Lung)
This is a vaping style where you draw vapor into your mouth first, then inhale it into your lungs. It mimics the draw of a traditional cigarette and is preferred by ex-smokers. MTL devices usually use higher-resistance coils and higher nicotine levels.
DTL (Direct-To-Lung)
In DTL vaping, the vapor is inhaled directly into the lungs without pausing in the mouth. It produces larger clouds and is common among experienced vapers. DTL requires sub-ohm coils and lower nicotine concentrations.
RDL (Restricted Direct Lung)
This is a hybrid of MTL and DTL. It allows for more vapor than MTL but with a tighter draw than full DTL. Many modern pod devices are designed to offer RDL compatibility.
Key Vape Glossary Terms You Should Know
These vaping terms pop up frequently in product descriptions, tutorials, and vape discussions. Understanding them helps you make better decisions as a beginner.
E-Liquid
Also called vape juice, e-liquid is the fluid vaporized by the device. It usually contains a mixture of PG (propylene glycol), VG (vegetable glycerin), nicotine (optional), and flavoring. E-liquids come in different strengths and compositions.
PG/VG Ratio
This refers to the proportion of propylene glycol to vegetable glycerin in e-liquid. PG provides a stronger throat hit and better flavor, while VG is thicker and creates more vapor. A 50/50 blend is balanced, while 70/30 VG/PG is better for cloud chasing.
Ohm
An ohm (Ω) is the unit of electrical resistance. In vaping, it measures the resistance of the coil. Lower ohms (below 1.0Ω) produce more vapor and are known as sub-ohm vaping. Higher ohms are used in MTL devices for stronger throat hits and less vapor.
Sub-Ohm
Sub-ohm vaping refers to using a coil with a resistance below 1.0 ohm. These setups are used for DTL vaping and create dense vapor clouds. They also require more power and consume more e-liquid.
Wattage
Wattage refers to the amount of power sent to the coil. Adjusting wattage allows you to control vapor production and flavor intensity. Most regulated mods let you choose your wattage manually.
Throat Hit
This is the sensation you feel in your throat when inhaling vapor. Higher nicotine levels and PG-rich e-liquids increase the throat hit. Many users who are quitting smoking look for a satisfying throat hit to replicate the feel of cigarettes.
Nicotine Salts
Nicotine salts (nic salts) are a form of nicotine used in many pod systems. They deliver a smoother throat hit and faster absorption than freebase nicotine, making them ideal for higher-strength nicotine delivery without harshness.
Dry Hit
A dry hit happens when there’s no e-liquid left in the coil, causing the cotton to burn. It produces an unpleasant taste and can damage your coil. Always ensure your coil is saturated before vaping.
Steeping
Steeping is the process of aging e-liquid to enhance its flavor. Some vapers let new e-liquids sit in a cool, dark place for a few days or weeks before use to improve taste.
Airflow Control
Many tanks and pods allow you to adjust the airflow to customize your vape draw. More airflow creates cooler, airier clouds; less airflow creates warmer, denser vapor.
Battery Safety
In regulated mods, built-in protections help avoid overheating or short circuits. For mechanical mods or external batteries, always understand Ohm’s Law and never carry batteries loose in your pocket.
Vape Juice Flooding
This occurs when too much e-liquid saturates the coil and causes gurgling or leaking. It can be prevented by proper coil priming and not overfilling your tank.
Priming the Coil
Priming a coil means adding a few drops of e-liquid to the exposed cotton before installation. This prevents dry hits and extends coil life by ensuring the wick is fully saturated before first use.
Chain Vaping
Chain vaping means taking multiple puffs without enough time between hits. This can overheat the coil and cause burnt hits. Let your device rest between drags to cool down and wick properly.
Mod Wattage Limits
Each coil is rated for a specific wattage range. Exceeding that limit can burn the coil and produce harmful chemicals. Always follow the manufacturer’s recommended settings.
Vaping Acronyms That Confuse Beginners

Common Vaping Mistakes Related to Terminology
A lack of understanding of vape terms often leads to beginner mistakes. For example, buying a sub-ohm coil for an MTL device, or filling a tank with high-strength nicotine salts meant for low-wattage pods. Knowing the right term helps match your device, e-liquid, and style for a smoother experience. Misunderstanding the PG/VG ratio can also affect satisfaction—high VG might clog an MTL coil, and high PG might feel too harsh in a sub-ohm setup.
