Introduction

Whether you are new to the community or have been using these devices for years, understanding exactly what is in vape pens is essential for a consistent and reliable experience. A vape pen is a sophisticated piece of technology that combines electrical engineering with fluid dynamics to produce vapor. At Vapor Authority, we believe that transparency regarding the components and ingredients used in these devices is the foundation of trust between a retailer and an adult consumer.

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.

When we look at a modern vape pen, we are looking at two distinct categories of "contents": the physical hardware components that make up the device and the chemical ingredients that constitute the e-liquid. Each part plays a specific role in how flavor is delivered and how the device performs over time. This guide provides a technical breakdown of the materials, electronics, and ingredients found in the vaping products we provide to our customers.

The Anatomy of Vape Pen Hardware

To understand what is in a vape pen, we must first look at the physical construction of the device. Most modern pod systems and All-In-One (AIO) kits consist of several primary sections that work in unison.

The Battery and Internal Electronics

The largest physical component inside a vape pen is the battery. Most portable devices use integrated vape batteries. These are preferred for their high energy density and ability to be recharged hundreds of times.

The capacity of these batteries is measured in milliamp-hours (mAh). A higher mAh rating generally indicates a longer run-time between charges. Inside the chassis, the battery is connected to a circuit board or chipset. This "brain" of the device regulates the voltage and wattage sent to the heating element. It also handles essential safety features, such as:

• Over-discharge protection: Prevents the battery from draining to a point where it could be damaged.
• Short-circuit protection: Automatically cuts power if an electrical fault is detected.
• Overheat protection: Monitors the internal temperature of the board.
• Cut-off timers: Limits the length of a single puff to prevent the coil from burning.

The Housing and External Materials

The exterior shell of a vape pen is typically constructed from durable, lightweight materials. Common options include zinc alloy, aluminum alloy, or high-grade plastics such as polycarbonate. These materials are chosen for their ability to withstand the heat generated by the device and for their durability during daily use. High-end devices may also feature decorative inlays such as leather, carbon fiber, or stabilized wood.

The Tank or Pod System

The tank (or pod) is the reservoir that holds the e-liquid. In most modern setups, these are made from Pyrex glass or food-grade PCTG plastic. Pyrex is particularly favored in larger tanks because it is resistant to "tank cracker" e-liquids—certain acidic flavors like citrus or cinnamon that can degrade standard plastics.

The Atomizer: The Core of the Device

If the battery is the heart of the vape pen, the atomizer is the engine. When people ask what is in a vape pen, they are often referring to the heating element that actually creates the vapor.

The Heating Coil

The coil is a small piece of resistance wire or a perforated metal mesh. When electricity passes through this metal, it encounters resistance, which generates heat. Common materials used for coils include:

• Kanthal (A1): An alloy of iron, chromium, and aluminum. It is the most common coil material due to its durability and stability at high temperatures.
• Stainless Steel (316L): A versatile metal that can be used in both wattage mode and temperature control mode.
• Nichrome (Ni80): An alloy of nickel and chromium that heats up faster than Kanthal, providing a quicker "ramp-up" time.
• Mesh: Rather than a traditional wire coil, mesh atomizers use a wide, flat strip of metal with holes punched in it. This increases the surface area in contact with the e-liquid, which often results in more vapor and more intense flavor.

The Wicking Material

Inside or around the heating coil is the wick. Its job is to draw e-liquid from the tank to the heating element via capillary action. In almost all high-quality devices, the wick is made from organic Japanese cotton. Some manufacturers also incorporate wood pulp or flax fiber into their wicks to improve heat resistance and liquid absorption speeds.

Resistance and Ohms

The performance of the atomizer is defined by its resistance, measured in ohms.

• Standard Resistance (1.0 ohm and above): These coils require less power and are typically used for "mouth-to-lung" (MTL) vaping, which mimics the draw of a traditional cigarette.
• Sub-Ohm Resistance (Below 1.0 ohm): These coils have less electrical resistance and require more power. They produce more vapor and are used for "direct-to-lung" (DTL) vaping.

What is in the E-Liquid?

Beyond the hardware, the most important part of "what is in a vape pen" is the e-liquid itself. At Vapor Authority, we carry exclusively US-made e-liquids to ensure that every bottle meets strict manufacturing standards. High-quality e-liquid generally consists of only four primary ingredients.

1. Vegetable Glycerin (VG)

VG is a thick, clear liquid derived from vegetable oils, typically soy, coconut, or palm oil. It is a USP-grade (United States Pharmacopeia) food additive. In e-liquid, VG is responsible for the density and volume of the vapor clouds. It has a slightly sweet natural taste and provides a smooth sensation on the throat.

2. Propylene Glycol (PG)

PG is a much thinner, odorless liquid that is also USP-grade. While VG produces the clouds, PG is the primary carrier for flavor and nicotine. It provides the "throat hit" that many adult vapers look for. Because it is thinner, e-liquids with a higher PG ratio are easier for smaller coils to wick, whereas high-VG liquids require larger sub-ohm coils to prevent the cotton from drying out.

3. Flavorings

The flavors in e-liquids are concentrated, food-grade flavorings. These are the same types of flavorings found in sodas, candies, and baked goods. E-liquid mixologists combine these concentrates to create complex profiles, ranging from traditional tobacco and menthol to fruits, desserts, and beverages. It is important to note that these flavorings are specifically formulated for inhalation and do not contain oils that could be harmful to the heating element.

4. Nicotine

Nicotine is extracted from tobacco plants and purified to meet pharmaceutical standards. It is available in various strengths, typically measured in milligrams per milliliter (mg/mL).

• 0mg: Nicotine-free e-liquid.
• 3mg to 6mg: Common for sub-ohm vaping.
• 12mg to 18mg: Common for MTL vaping in standard starter kits.

Nicotine Salts vs. Freebase Nicotine

There are two distinct types of nicotine found in vape pens today:

• Freebase Nicotine: This is the standard form of nicotine used in the industry for decades. It provides a more noticeable throat hit at higher concentrations.
• Nicotine Salts: This form of nicotine is created by adding an acid (usually benzoic acid) to freebase nicotine. This lowers the pH level, resulting in a much smoother experience even at high concentrations (such as 25mg to 50mg). Nicotine salts are almost exclusively used in low-power pod systems.

Quality Standards and Sourcing

Knowing what is in your vape pen also means knowing where it came from. The vaping industry has seen an influx of counterfeit products and "clones" that may use inferior materials or lack essential safety features.

At Vapor Authority, we only purchase directly from the original equipment manufacturers (OEMs) or their authorized distributors. This ensures that the zinc alloys, Pyrex glass, and lithium-ion batteries in your device are authentic and meet the specifications intended by the designers. Furthermore, every e-liquid we stock is manufactured in the United States using food-grade and pharmaceutical-grade ingredients. These liquids are tested by our team before they are added to our inventory to ensure they meet our standards for flavor and consistency.

Battery Safety

Since the battery is a core component of what is in a vape pen, proper handling is vital. Most vape pens have internal batteries, but some larger mods use external 18650 or 21700 batteries.

Essential Battery Tips

• Inspect the Wrap: If you use a device with external batteries, always check the plastic "wrap" for nicks or tears. If the metal of the battery is exposed, do not use it; it must be re-wrapped or replaced.
• Use the Right Charger: Always use the charging cable provided with your device or a dedicated external charger from a reputable brand. Avoid using "fast-chargers" designed for cell phones unless your device specifically supports that amperage.
• Storage: Never carry loose batteries in your pocket or bag. If they come into contact with metal objects like keys or coins, they can short-circuit. Always use a plastic battery case for transport.
• Temperature Control: Do not leave your vape pen in a hot car or in direct sunlight for extended periods. Excessive heat can degrade the battery chemistry and lead to failure.

Maintenance of Your Vape Pen Components

To keep your device functioning as intended, regular maintenance of its internal and external components is required.

Cleaning the Tank and Connections

Over time, e-liquid residue can build up in the "chimney" of the tank or around the 510 connection (the threaded point where the tank meets the battery). Use a cotton swab or a paper towel to wipe these areas clean once a week. If you are changing flavors, you can rinse your glass tank sections in warm water, but ensure they are completely dry before reassembling.

Replacing the Coil

The coil is a consumable component. As the organic cotton wick is heated repeatedly, it will eventually begin to degrade, and the metal heating element will collect "caramelized" sugars from the e-liquid flavoring. You will know it is time to change the coil when the flavor begins to taste muted or "burnt," or if the vapor production drops significantly. On average, a coil lasts between one and two weeks depending on the sweetness of your e-liquid and how frequently you vape.

Priming the Coil

When you install a new coil, you must "prime" it. This involves dripping a few drops of e-liquid directly onto the exposed cotton of the coil before installing it. After filling the tank, let it sit for 5 to 10 minutes. This ensures the wick is fully saturated, preventing the cotton from burning the first time you press the fire button.

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 available with 0mg nicotine for those who prefer it.

How do I know if my vape pen is authentic?

Authentic hardware from reputable manufacturers will include an "authenticity code" on the packaging that can be verified on the manufacturer's website. At Vapor Authority, we only sell 100% authentic products purchased directly from the manufacturer or authorized distributors to ensure our customers receive genuine gear.

What is the difference between a coil and an atomizer?

While the terms are often used interchangeably, the atomizer is technically the entire housing that contains the heating element, while the "coil" is the specific wire or mesh and wick that heats up. Most modern vape pens use replaceable coil heads that screw or press into the tank or pod.

Why does my vape pen taste burnt?

A burnt taste usually means the cotton wick inside your coil has become dry or charred. This can happen if the e-liquid level is too low, if the wattage is set too high for the coil's rating, or if the coil has reached the end of its lifespan and needs to be replaced.
