Inhale – The act of breathing vapor into your lungs or mouth. There are two kinds: direct-to-lung inhale and mouth-to-lung inhale. Lung inhaling is when vapor goes straight to your lungs. This is often used by cloud chasers and high wattage users. Mouth-to-lung inhale is when vapor is inhaled to the mouth, then to the lungs. This type is the most common, and is the same kind of inhale used by cigarette smokers.
Juice – A shorthand term for e-liquid.
Leaking – When e-juice leaks out of an atomizer/tank/cartomizer, etc. This can cause damage to e-cigarettes if the e-juice starts to leak into the battery. Occasional natural leaking of some tanks occur because of the airflow.
LED – Stands for “light emitting diode.” This is the light on the ends of cig-a-likes to simulate the glow of traditional cigarettes. It also doubles as a warning light when the battery need to be recharged.

Mechanical Mod – Also referred to as mech mods, mech PVs, or mechs, these are e-cigarette models that don’t have any wires or regulating chips. Usually made of a metal tube with a manual switch that is pressed to complete the circuit, mech mods can also come in box shapes, or in converted battery cases, mint cases, etc.
mg – Stands for milligram strength per milliliter. This is used to determine the nicotine strength of e-liquid. For example, “6mg” means 6mg of nicotine per ml, or 0.6%.
Mini – A term to describe smaller, stealthier versions of standard vaping models.
Mod – Short for “modifications,” vape mods usually employ larger batteries to give users longer battery life and stronger vapor production at the cost of size and portability. Mods are built to give users the ability to experience optimal performance of their equipment. Mods are available in mechanical or variable versions.
Mouth-to-Lung Hit – Also called “French inhale,” this is the traditional way of inhaling smoke by cigarette smokers. For vapers, vapor is inhaled into the mouth, then inhaled to the lungs. While providing less vapor than direct lung inhalers, this method provides more flavor.
Nicotine – Also called “nic,” this is the substance found in cigarettes and some e-liquid to give smokers and vapors what is called a “nicotine high.” Nicotine by itself is as harmless as caffeine, with both being vasoconstrictors. E-liquids have varying amounts of nicotine, ranging from 0mg to 24mg.
Ohm – The unit of measurement used for electrical resistance. A lower ohm reading for coils means hotter and thicker vapor, while a higher ohm reading means cooler vapes with less vapor production.
Organic Cotton – A type of wick that’s gaining popularity for use in rebuildable atomizers and tanks, organic cotton burns quicker than silica but offers cleaner, more intense flavor.
Parallel – When mods that can use two batteries are wired as parallel, this gives increased battery life, effectively doubling the mAh. Voltage and voltage drop remain the same.
Pass-through – When an vape model is described as having pass-through capabilities, this means the unit can be used while it is charging, connected to a cable. It can also refer to pass-through models in which no batteries are present, but are instead powered by plugging the USB cable into an adaptor, computer, or power bank.

Personal Vaporizer – Also called PV for short, this is another name for vapes, particularly for mods and nontraditional cig-a-like units.
Propylene Glycol (PG) – One of two base substances used in e-liquid. PG is an over-the-counter substance used in many food and drink items.
Priming – Before using a new atomizer, a few drops of liquid are added then made to sit for a few minutes to let the e-liquid saturate the wick fully. The same holds true for newly filled tanks, cartomizers, and clearomizers.
Rebuildables – This can refer to either tanks or atomizers that let users rebuild their own coils and wicks. Used mostly by advanced users, rebuildables allow vapers to adjust resistance, change out different wicks, and experiment with various setups to achieve their preferred vapes.
RDA – The abbreviation for “Rebuildable Dripping Atomizer”. Able to build your own coils or purchase pre-built coils to find the ohm rating that will work best for you.
Resistance – Measured in ohms, resistance depends on the thickness of wire used in a coil, the number of coils, the circumference of the coils, and how thick the coils are wound.
RBA – Short for “Rebuildable Atomizer”
RTA – Short for “Rebuildable Tank Atomizer”
Series – For mech mods with dual battery configurations that are wired in series, this effectively doubles the voltage output at the expense of battery life.

Steeping – A term used to describe the act of letting newly mixed e-liquid sit for a day to several weeks to let the ingredients settle and mix together more. Some liquids can be steeped for added flavors and notes.
Sub-ohming – A practice used by experienced vapers to produce massive clouds of vapor by building coils with ohm readings below 1.0 ohm.
Tank – Clearomizers with bigger capacity enclosures made of glass or plastic, which are able to hold larger amounts of e-liquid. They can either be fitted with punched cartomizers, pre-built coils, or rebuildable decks.
Throat Hit – The sensation after vapor hits the throat. Many vapers look to simulate the harsh throat hit of cigarettes, while some prefer a smoother throat hit.
Tube Mod (Mech Mod) – A term used to describe vapes or PVs that come in a tube shape about the size of a small flashlight.
USB Charger – A charger that is plugged into a USB port from which it draws power. It can either refer to a cable that is plugged directly into a vape, or a separate unit that’s used to recharge batteries.
Vape - Can either be the production of vapor, the device, the act of vaping, and many other uses.
Vaper – A term used to describe anyone who uses vaping devices.
Vaper’s Tongue – A sensation felt when a user uses too much of one flavor, causing the tongue to become desensitized. It can also refer to the tickling sensation on the tongue after a long vape session. To clear that up, temporarily switching flavors is recommended.
Vapor – The result of atomizing e-liquid, this is also referred to as “clouds.” This is the main factor in vaping that simulates smoke to give smokers a safer alternative to traditional cigarettes.
Vapor Production – A term used to describe the amount of vapor a vape or e-liquid produces.
Vegetable Glycerol or Glycerine (VG) – One of two base ingredients used in the production of e-liquid. Vegetable Glycerol typically produces more vapor than Propylene Glycol (PG). Users who are allergic to PG often use 90% or 100% VG solutions.
Voltage Drop – This refers to the drop in power typically experienced by mech users. Fresh batteries have an output of 4.2v, and as the voltage drops, so does the power and vapor production of the vape.
VV or Variable Voltage – Any type of vape that allows users to adjust its voltage output according to taste, it is considered superior to regular PVs that have static voltage outputs.
VW or Variable Wattage – Variable Wattage devices allow users to adjust the wattage output of their PV. The PV adjusts power according to the set wattage, and is the main difference between VW and VV.
Wick – Usually made from silica, other materials used for wicks include stainless steel mesh, organic cotton and ceramic. The main purpose of the wick is to hold and deliver e-liquid to the heating element of a vape in a controlled manner so as to prevent flooding.
Wire – This is the term that refers to the material used in an atomizer’s coil.
Wrap – This refers to the number of revolutions used in the wrapping of a coil. The more wraps a coil has, the higher the resistance.
