If you are new to vaping or just picked up your first device, you might be wondering how a vape works exactly. The process sounds technical when you hear terms like coil resistance, wicking material, and draw activation, but the underlying mechanics are straightforward once broken down step by step. This guide explains everything clearly, from the battery to the vapour you exhale, with practical detail that applies to every major device type available in our online vape store.
How Does Vaping Work at a Basic Level
At its core, a vape device uses battery power to heat a coil, which in turn heats e-liquid until it turns into vapour. You inhale that vapour, get your nicotine or flavour hit, and exhale. The whole cycle happens in under a second.
No combustion takes place at any point. This is the fundamental difference between vaping and smoking. A cigarette burns tobacco at high temperatures, producing smoke through combustion. A vape heats liquid below combustion temperature, producing vapour through evapouration. The process, the output, and the compounds involved are all different.
Understanding how vaping works starts with understanding the four main components every vaping device shares, regardless of whether it is a disposable, a pod system, or an advanced mod.
The Four Core Components of Every Vape Device
The Battery
The battery is the power source of the device. In disposable vapes, the battery is sealed inside and not replaceable. In pod systems and mods, the battery is either built-in and rechargeable via USB or removable and replaceable with external cells.
Battery capacity is measured in milliampere-hours, or mAh. A higher mAh rating means more puffs before recharge. Disposable devices typically have smaller batteries sized to match their pre-filled liquid capacity. Rechargeable devices have larger batteries that can handle hundreds of charging cycles.
Most modern vaping devices use lithium-ion batteries. These are the same battery technologies found in smartphones and laptops. They are efficient, compact, and capable of delivering consistent power output throughout the charge cycle.
The Coil
The coil is the heating element inside the device. It is a small length of resistance wire, typically made from kanthal, stainless steel, or nichrome, wrapped into a spiral around a wicking material. When the battery sends electrical current through the coil, the resistance of the wire converts that electricity into heat.
Coil resistance is measured in ohms. Lower resistance coils, often below 1 ohm and called sub-ohm coils, run at higher wattage and produce more vapour and flavour intensity. Higher resistance coils run at lower wattage and produce a tighter, more cigarette-like draw.
The coil is the component that wears out over time in refillable devices. A coil that has reached the end of its lifespan produces a burnt flavour because the wicking material has degraded. Replacing the coil restores clean flavour. In disposable devices, the coil is built in and not replaceable.
The Wicking Material
Wrapped around or threaded through the coil is a wicking material, most commonly organic cotton. The wick draws e-liquid from the tank or pod reservoir to the coil through capillary action. When the coil heats up, the liquid saturating the wick vaporizes.
Proper wicking is critical to clean, consistent vapour production. If the wick dries out from vaping too quickly, the coil burns the cotton instead of vaporizing liquid, producing the harsh burnt taste that vapers try to avoid. This is why taking slower, spaced-out puffs helps preserve coil life in refillable devices.
The Tank or Pod
The tank or pod holds the e-liquid that feeds the coil. In disposable vapes, this is a sealed chamber factory-filled with liquid. In closed pod systems like STLTH, the pod is pre-filled and snaps into the device. In open pod systems and mods, the user fills the tank or pod themselves with the e-liquid of their choice.
Tank capacity varies significantly across device types. Small pod systems typically hold 1 to 4 millilitres of liquid. Larger sub-ohm tanks hold 5 millilitres or more. The capacity determines how frequently you refill or replace the pod.
How Does a Disposable Vape Work
Disposable vapes like Geek Bar, Flavour Beast, and Oxbar are the most popular vaping products in Canada. Understanding how a disposable vape works helps you get the most out of the device and avoid common mistakes.
A disposable vape has all four components built into a single sealed unit. The battery, coil, wicking material, and e-liquid reservoir are integrated and cannot be separated. When the device arrives, it is already primed, filled, and ready to use immediately.
Most disposables are draw-activated. There is no button. When you inhale through the mouthpiece, a sensor detects the airflow and activates the battery, which powers the coil, which vaporizes the liquid in the wick. The cycle completes in the time it takes you to draw.
Rechargeable disposables have a USB-C port that lets you recharge the battery when it runs low, extending use until the e-liquid itself is depleted. Non-rechargeable disposables are fully spent when either the battery or liquid runs out.
The device stops producing vapour either when the battery is fully drained or when the liquid reservoir is empty. At that point, the device is disposed of. Most disposable vapes produce between a few hundred and tens of thousands of puffs depending on their liquid capacity and battery size.
How Does a Pod Vape Work
Pod systems are the next step up from disposables in terms of flexibility and long-term cost. Understanding how a pod vape works explains why they are the preferred daily driver for many vapers in Canada.
A pod system consists of a reusable battery device and replaceable pods. The pod contains the coil and the liquid reservoir. When the pod is inserted into the device, the electrical contacts connect the battery to the coil.
In closed pod systems like STLTH or Vuse, the pods come pre-filled from the manufacturer. You snap in a new pod when the current one runs out and carry on. In open pod systems like Vaporesso XROS or Uwell Caliburn, you fill the pod yourself with your preferred e-liquid.
Draw-activated pod systems work identically to disposables in terms of activation. You inhale and the device fires automatically. Button-activated pod systems require pressing a fire button while inhaling. Some devices offer both options.
The pod itself contains the wicking material and coil. Over time, the coil degrades. In closed systems, replacing the pod replaces the coil automatically. In open systems with replaceable coils, you swap the coil separately and keep the pod shell.
How Do Vape Mods Work
Vape mods are advanced devices primarily used by experienced vapers who want more control over their experience. How vape mods work is a fair question for anyone who has graduated from pod systems.
A mod is essentially an advanced battery unit that regulates power output to a connected atomizer or tank. Unlike simple pod systems that operate at a fixed wattage, mods allow users to set the wattage, voltage, and sometimes temperature of the coil precisely.
The mod connects to a tank via a threaded 510 connection, the industry standard connector used across virtually all tanks and atomizers. The mod reads the resistance of the coil in the tank and calculates safe operating parameters. When you press the fire button, the mod delivers the set wattage to the coil, which vaporizes the liquid in the tank.
Most mods have a digital display showing wattage, voltage, resistance, and battery level. They can support external batteries, typically 18650 or 21700 lithium-ion cells, which allows you to swap batteries for continuous use without waiting for a recharge.
Mods produce more vapour, more flavour intensity, and more customization than pod systems, but they require more knowledge to operate safely. Battery safety, coil resistance limits, and proper tank maintenance are all areas an aspiring mod user needs to understand before getting started.
How Does Vape Juice Work Inside the Device
Once you understand the hardware, the next question is how vape juice work within that system. The e-liquid is not just a passive ingredient. Its composition directly affects how the device performs.
Vape juice is a mixture of propylene glycol, vegetable glycerin, flavourings, and optionally nicotine. The ratio of PG to VG affects viscosity. High-VG liquids are thicker and produce more vapour. High-PG liquids are thinner and carry flavour more intensely. Very thick liquids can struggle to wick properly in fine-bore coils, leading to dry hits.
Nicotine salts, the form of nicotine used in most Canadian disposables and pre-filled pods, absorb faster into the bloodstream than freebase nicotine. They are smoother at higher concentrations, which is why nic salt devices deliver a satisfying experience at the nicotine levels smokers typically need.
Freebase nicotine is used in larger sub-ohm tanks and mod setups at lower concentrations. It produces a more noticeable throat hit and is better suited to high-wattage, high-vapour devices where the large volume of vapour compensates for the lower nicotine concentration per millilitre.
How Does Vaping Work in Your Body
When you inhale vapour from any vaping device, the aerosol carries nicotine and flavour compounds into your lungs. From the lungs, nicotine crosses into the bloodstream and reaches the brain within seconds. The speed of absorption depends on the delivery method. Nicotine salts absorb faster than freebase nicotine, which is why nic salt devices feel more immediately satisfying for smokers switching to vaping.
The aerosol also contains water vapour, propylene glycol particles, and vegetable glycerin particles alongside any flavouring compounds present in the liquid. These are exhaled as the visible vapour cloud that leaves the device.
Health Canada notes that while vaping carries fewer risks than smoking combustible tobacco, it is not without its own health considerations. For vapers who smoke and are considering switching, vaping as a complete replacement for cigarettes is understood to be the harm reduction goal. You can review Health Canada's current guidance through their vaping information resource.
Common Reasons a Vape Stops Working
Since vapers in Canada often search for why their device is not working, here is a quick practical breakdown.
If your vape is not working after charging, the issue is often a connection problem between the pod and the device. Remove the pod, clean the contacts with a dry cotton swab, and reseat it firmly.
If your disposable vape stops producing vapour but still has battery, the liquid is likely depleted. Disposables cannot be refilled. If the device is rechargeable and the liquid runs out before the battery, the device is finished.
If your refillable pod tastes burnt, the coil has degraded and needs replacing. Do not try to push through a burnt coil. Replace the coil or pod immediately to avoid inhaling degraded wicking material.
If your vape only works when plugged in, the battery has lost capacity and can no longer hold a charge. For devices with removable batteries, replacing the cell solves this. For sealed devices, the device has reached the end of its lifespan.

Frequently Asked Questions
How does a vape work in simple terms for someone who has never used one before?
A vape uses a battery to heat a coil, which vaporizes the liquid held in a tank or pod. You inhale the vapour through the mouthpiece. No tobacco burns and no smoke is produced. Most Canadian beginners start with a draw-activated disposable, which requires no buttons, settings, or setup to use.
How does a disposable vape work, and why does it stop producing vapour?
A disposable vape fires automatically when you inhale. The battery powers the coil, which heats the liquid in the sealed reservoir. Vapour stops when either the liquid runs out or the battery depletes completely. Rechargeable disposables can be charged to extend use, but the liquid itself cannot be refilled in a sealed disposable device.
How do vape mods work differently from simple pod systems?
Vape mods allow you to set precise wattage and voltage output to a connected tank. Pod systems operate at a fixed or limited wattage without user-adjustable settings. Mods connect to tanks via a universal 510 thread, support larger batteries, and produce significantly more vapour and flavour intensity than pod systems at the cost of more complexity.
How does vape juice work with different coil types in the same device?
Vape juice viscosity needs to match the coil and wicking system in the device. High-VG thick liquids work well in sub-ohm tanks with large wicking ports. High-PG thinner liquids suit fine-bore pod coils. Using the wrong ratio causes dry hits or flooding. Pre-filled pods eliminate this problem by matching the liquid to the coil from the factory.
How does vaping work in your body compared to smoking a cigarette?
Vaping delivers nicotine through inhaled aerosol rather than combustion smoke. Nicotine crosses from the lungs into the bloodstream rapidly, particularly with nic salt e-liquids. Unlike smoking, vaping does not produce tar or carbon monoxide from combustion. Health Canada acknowledges vaping presents fewer risks than smoking for smokers who switch completely.
