Introduction
Understanding exactly what are in vape pens is a common priority for adult vapers. Whether you are new to the community or an experienced enthusiast, knowing the components and ingredients of your device ensures a better experience. At Vapor Authority, we believe that transparency regarding hardware and e-liquids is essential for making informed choices. (vaporauthority.com)
The term "vape pen" actually refers to two distinct categories of components: the physical hardware and the e-liquid. Each part plays a specific role in creating the vapor you inhale. This guide provides a detailed breakdown of the mechanical parts and the chemical ingredients found in modern vaping products.
Warning: This content is intended for adults of legal vaping age only. Vaping products contain nicotine, which is an addictive chemical. These products are not intended for use by minors, non-smokers, pregnant or breastfeeding women, people with heart conditions, high blood pressure, or asthma. Consult a physician if you have concerns about whether vaping products are appropriate for you.
The Physical Anatomy: What Hardware Is in a Vape Pen?
To understand what are in vape pens, you must first look at the mechanical structure. A vape pen is a handheld electronic device that uses a battery to heat a coil. This heat vaporizes a liquid solution. While designs vary between brands, the fundamental components remain largely the same across the industry.
The Battery and Internal Circuitry
The battery is the power source of the device. Most vape pens use lithium-ion batteries due to their high energy density and rechargeability. These batteries are often measured in milliamp-hours (mAh). A higher mAh rating typically indicates a longer life between charges.
In many starter kits, the battery is integrated into the device body. In larger box mods, the batteries may be external and removable. The battery housing also contains a small circuit board. This board regulates the power output and includes safety features. These features prevent short circuits, overcharging, and overheating during use. (vaporauthority.com)
The Atomizer and Coil
The atomizer is the component where the actual vaporization happens. Inside the atomizer is the coil. The coil is a small heating element made of resistive wire or metallic mesh. Common materials include Kanthal, Stainless Steel, or Nichrome. (vaporauthority.com)
The coil is wrapped around a wicking material, which is almost always organic cotton. The wick soaks up the e-liquid from the tank. When you activate the device, the battery sends electricity through the coil. The coil gets hot, and the e-liquid in the wick turns into vapor.
Coils are measured by their electrical resistance in "ohms." Sub-ohm vaping refers to using a coil with a resistance of less than 1.0 ohm. This setup typically produces more vapor and requires higher wattage. Higher resistance coils (above 1.0 ohm) produce less vapor and are often used for a tighter draw.
The Tank or Pod Reservoir
The tank or pod is the chamber that holds the e-liquid. In traditional vape pens, this is often a glass or plastic tank that screws onto the battery. Modern replacement pods use replaceable plastic cartridges instead. (vaporauthority.com)
Tanks are usually made of Pyrex glass or high-grade plastics like PCTG. These materials are chosen because they do not react with the flavorings in the e-liquid. The reservoir also includes a chimney—a hollow tube that directs the vapor from the coil to the mouthpiece.
The Mouthpiece or Drip Tip
The mouthpiece, also known as a drip tip, is the part you inhale through. These are often removable and come in different sizes. A narrow mouthpiece is designed for mouth-to-lung (MTL) vaping, which mimics the sensation of a traditional cigarette. A wider mouthpiece is used for direct-to-lung (DTL) vaping, allowing for more airflow and larger vapor clouds.
The Ingredients: What Is in the E-Liquid?
When people ask what are in vape pens, they are often referring to the e-liquid itself. E-liquid, also known as vape juice or e-juice, is a simple mixture of four primary ingredients. At Vapor Authority, we only carry e-liquids manufactured in the USA using food-grade and pharmaceutical-grade ingredients. (vaporauthority.com)
Vegetable Glycerin (VG)
Vegetable Glycerin is a thick, colorless, and odorless liquid. It is typically derived from vegetable oils, such as palm, soy, or coconut oil. In the vaping industry, it is used as a base for the e-liquid.
VG is responsible for the "clouds" or the visible vapor production. It has a slightly sweet taste and is very viscous. Because of its thickness, e-liquids with a high VG content (70% or more) are better suited for sub-ohm tanks with large wicking holes. If a high-VG liquid is used in a small pod system, it may not wick fast enough, leading to a "dry hit." (vaporauthority.com)
Propylene Glycol (PG)
Propylene Glycol is the second base ingredient. It is much thinner than VG and is odorless and tasteless. PG is a highly effective carrier for flavorings and nicotine.
The primary role of PG is to provide a "throat hit." This is the slight tingling sensation in the back of the throat during inhalation. Because PG is thin, it is absorbed by the wick very quickly. E-liquids with a higher PG ratio are common in starter kits and pod systems.
Flavorings
Flavorings are what give each e-liquid its unique profile. These are typically concentrated, food-grade flavorings similar to those used in the baking and candy industries. However, they are specifically formulated for inhalation.
The flavoring component usually makes up a small percentage of the total liquid. Flavor profiles range from simple tobacco and menthol to complex desserts, fruits, and cereals. It is important to note that even though these flavorings are used in food, they are mixed in precise ratios to ensure they vaporize correctly without leaving excessive residue on the coil.
Nicotine
Nicotine is an optional ingredient in most e-liquids. Many brands offer "0mg" versions for those who enjoy the flavor without the stimulant. For those who do use nicotine, it is available in various strengths and two different chemical forms.
- Freebase Nicotine: This is the traditional form of nicotine used in vaping. It is effective but can become harsh at higher concentrations. It is usually found in strengths like 3mg, 6mg, and 12mg.
- Nicotine Salts: This form is created by adding an acid (usually benzoic acid) to freebase nicotine. This lowers the pH level, resulting in a much smoother throat hit even at high concentrations. Nicotine salts are typically found in 25mg to 50mg strengths and are intended for low-power pod systems.
Understanding PG/VG Ratios
The balance between Vegetable Glycerin and Propylene Glycol is known as the PG/VG ratio. This ratio determines how the vape pen will perform and which devices it is compatible with.
- 50/50 Ratios: These provide an equal balance of flavor, throat hit, and vapor. They are ideal for pod systems and high-resistance coils.
- 70/30 (High VG) Ratios: These are the industry standard for sub-ohm vaping. They produce dense clouds and a smoother inhale but require more power to vaporize effectively.
- Max VG: These liquids contain as much VG as possible, usually over 80%. They are used by "cloud chasers" who want the maximum possible vapor production.
Choosing the right ratio for your device is crucial. Using a high-VG liquid in a small pen may cause the coil to burn out prematurely. Conversely, using a thin high-PG liquid in a high-power tank may result in leaking.
The Role of Airflow and Sensors
What are in vape pens also includes the internal air path. Most devices have adjustable airflow slots. By opening or closing these slots, you change the temperature and density of the vapor.
Many modern vape pens also feature "draw-activated" sensors. Instead of pressing a button, a small pressure sensor detects when you are inhaling. This sensor completes the circuit and activates the heating element. Button-activated devices, on the other hand, give the user more control over when the coil begins to heat.
Battery Safety for Vape Pen Users
Since vape pens are powered by lithium-ion batteries, practicing proper battery safety is vital. While most regulated devices from Vapor Authority have built-in protections, the user still plays a role in maintaining safety.
Practical Safety Tips:
- Inspect the Wrap: If you use a device with external batteries, always check the plastic wrap. If the wrap is torn or peeling, do not use the battery.
- Use the Correct Charger: Always use the cable provided with the device or a high-quality external charger. Avoid using high-speed "fast chargers" meant for tablets or laptops unless the manufacturer specifies they are compatible.
- Storage: Never carry loose batteries in your pocket or bag. They can contact metal objects like keys or coins, causing a short circuit. Use a dedicated plastic battery case.
- Temperature Control: Do not leave your vape pen in a hot car or in direct sunlight. Extreme heat can degrade the battery and lead to failure.

FAQ
What are the main ingredients in e-liquid?
The four primary ingredients are Vegetable Glycerin (VG), Propylene Glycol (PG), food-grade flavorings, and nicotine. VG provides the vapor clouds, while PG carries the flavor and provides the throat hit. Some e-liquids are nicotine-free, containing only the first three ingredients.
Is the nicotine in vape pens different from tobacco?
Vape pens use nicotine extracted from tobacco plants or synthetic nicotine created in a lab. It is available as freebase nicotine or nicotine salts. Nicotine salts use an added acid to make the vapor smoother at higher concentrations, whereas freebase nicotine is the standard form used in most traditional e-liquids.
What is the coil in a vape pen made of?
The coil is typically made of a metallic wire or mesh, such as Kanthal, Stainless Steel, or Nichrome. This wire is wrapped around a wick, usually made of organic cotton. When the battery is activated, the wire heats up to vaporize the e-liquid that has been absorbed by the cotton.
Can I use any e-liquid in any vape pen?
Not necessarily. The viscosity of the e-liquid must match the device's capabilities. High-VG liquids are thick and require sub-ohm tanks with large wicks and high power. Thinner high-PG or nicotine salt liquids are better suited for low-power pod systems and starter kits. Always check your coil's resistance before choosing a liquid.
