Different types of vape devices and E- cigarette

A vape, or electronic cigarette (e-cigarette), is a device that heats a liquid into an inhalable aerosol, commonly referred to as "vapour." Unlike traditional cigarettes, vapes don’t burn tobacco. Instead, they use a battery-powered heating element (atomizer) to vaporise e-liquid, which typically contains nicotine, flavourings, and other substances like cannabis extracts (THC or CBD). This act of inhaling aerosol is known as vaping.

Over time, vaping tech has evolved through four key generations. First-gen devices are simple disposables. Second-gen vapes feature prefilled or refillable cartridges. The third generation brought in tanks and mod boxes that offer customisation, letting users tweak voltage, coil resistance, and more. Fourth-gen devices, known as pod mods, combine sleek design with power and come in both refillable and prefilled forms. Below is an image that represents the evolution of vaping devices.

With so many types available, choosing the right vape depends on your experience level, preferences, and what you’re vaping. Below is a tabular comparison of different e-cigarettes types to help you understand what’s out there and what might suit you best.

What Are Different Types Of Vape?

The main types of vape devices include cigalikes, vape pens, disposables, pod systems, box mods, MTL (mouth-to-lung) vape kits, and DTL (direct-to-lung) sub-ohm devices. Each has its own design, functionality, and ideal user, ranging from beginner-friendly options to advanced, customisable setups. Here’s an explanation of each type of vape:

1. Cigalikes
   These are slim, cigarette-shaped vapes designed to mimic the look and feel of smoking. They're simple, often disposable or using replaceable cartridges, and great for new users.
   
   

2. Vape Pens
   Vape pens are slightly larger than cigalikes, and offer better battery life and refillable tanks. They're a popular pick for casual vapers who want a step up in performance without too much complexity.
   
   

3. Disposable Vapes
   Disposable Vapes are precharged and prefilled devices that are the easiest to vape; no refilling, no buttons, just inhale and toss when it's empty. They are ideal for convenience or short-term use.
   
   

4. Pod Systems
   Pod vapes use small pods instead of tanks. They come in refillable or prefilled versions and are compact, sleek, and perfect for nicotine salts or discreet vaping.
   
   

5. Box Mods
   Box mods are powerful, advanced devices with customisable settings. Users can adjust wattage, change coils, and pair them with different tanks for a tailored vape experience.
   
   

6. MTL (Mouth-To-Lung) Vape Kits
   MTL vape kits are devices that replicate the draw of a traditional cigarette, a tight inhale to the mouth, then the lungs. They are best for higher nicotine strengths and a smooth, cigarette-like feel.
   
   

7. DTL (Direct-To-Lung) Vape Kits
   DTL vape kits, also known as Sub-Ohm Vape Kits, are devices designed for massive clouds and intense flavour. These vapes use low-resistance coils and a direct lung inhale method. They are perfect for cloud chasers and seasoned vapers.

1) Cigalikes

Cigalike e-cigarettes are compact, cigarette-inspired vape devices designed to replicate the sensation of smoking in both form and function. Unlike more complex vapes, cigalikes are built for simplicity and familiarity, making them an ideal entry point for smokers looking to transition away from tobacco. The name “cigalike” comes from its visual similarity to a traditional cigarette, a feature that helps satisfy both the psychological and physical habits formed over years of smoking.

The structure of a cigalike consists of five main components: an indicator light, which glows when you inhale to simulate the burning tip of a cigarette; a battery, typically rechargeable, that powers the device; an atomising device (or coil), which heats the e-liquid to produce vapour; a liquid container, often a prefilled cartridge or cartomiser that holds the e-liquid; and an inhaler, or mouthpiece, through which the vapour is drawn. These parts are usually enclosed in a two-piece setup: one part for the battery, the other for the cartridge and atomiser combined. Refer to the following image for a visual representation of these components in a cigalike.

Cigalike devices are best suited for beginners, and the device functions on mouth-to-lung (MTL) vaping style, which closely mimics the way people smoke a cigarette, drawing vapour into the mouth first and then inhaling into the lungs. This makes the transition much easier for long-time smokers, especially since cigalikes typically deliver a tighter draw and smaller vapour clouds, just like a real cigarette. They're often paired with higher nicotine concentrations to satisfy cravings quickly without the need for frequent use.

Most cigalikes come with prefilled cartridges, some of which are disposable (also called disposable cigalike devices), while others can be swapped out and replaced. Many also use automatic draw activation, meaning there's no button to press, just inhale, and it works. While they may not offer the customisation or power of more advanced vapes, cigalikes are all about convenience, ease of use, and that familiar, cigarette-like experience.

2) Vape Pens

A vape pen is a slim vaping device that offers a balance between simplicity and performance. Named for its pen-like shape, this device is often the next step up from cigalikes, providing users with a slightly more advanced, customisable experience. Vape pen devices come in both pre-filled and refillable formats. These devices are rechargeable and often reusable, making them a cost-effective and beginner-friendly option for those who want more control over their vaping routine without sacrificing convenience.

A vape pen features an indicator light to show when the device is in use or charging, a battery that powers the unit, and a power button that must be pressed to activate the coil. The connector and thread join the battery to the atomiser, which sits inside the cartridge chamber or tank where the e-liquid is stored. At the core is the atomiser, containing a coil and wick system that heats up the soaked e-liquid into inhalable vapour. Finally, the mouthpiece allows for a direct draw and can be removed for refilling the tank. Refer to the following image for a visual representation of these components.

Vape pens cater to both beginners and intermediate users. They typically use a mouth-to-lung (MTL) draw but can also be adapted for direct-to-lung (DTL) depending on the coil and airflow settings. The design is compact enough for portability yet powerful enough for all-day vaping, and many models allow adjustable airflow for a tailored inhale. 

3) Disposable Vapes

A disposable vape is a compact, all-in-one vaping device that comes prefilled with e-liquid and a built-in battery, designed to be used straight out of the box and thrown away once finished. Unlike traditional vape kits that require charging and refilling, disposables offer a hassle-free vaping experience with zero maintenance. 

Disposable vapes consist of a coil, a cotton wick soaked in e-liquid, and a battery, all sealed inside a small, portable casing. There's no button to press; most activate automatically when you inhale. These devices are precharged and prefilled, making them perfect for anyone who doesn’t want to deal with coil replacements, tank cleaning, or e-liquid refills.

Disposables are ideal for new vapers transitioning from smoking. They mimic the draw and nicotine delivery of a cigarette, making them ideal for mouth-to-lung (MTL) vaping. The inhale is tight and controlled, delivering a noticeable throat hit and rapid nicotine hit. They are typically used with nicotine salt e-liquids, which absorb faster and deliver a smoother hit at higher strengths.

Most disposables are designed with a sleek, pen-style body that fits comfortably in the pocket or hand. Their design is focused on discretion, portability, and ease of use. Some come with LED indicators to show battery life or puff activation, while others include mesh coils to improve flavour and vapour production. Puff count varies from 400 to over 15000, depending on the model.

There are two main types of disposable vapes: rechargeable and non-rechargeable. Non-rechargeable disposables are the most common. Once the battery or e-liquid runs out, the whole device is discarded. Rechargeable disposables, on the other hand, allow you to recharge the battery via USB-C to ensure you get every last drop of e-liquid before tossing it. These often have a larger e-liquid capacity and offer longer usage time, making them more economical and eco-conscious compared to traditional disposables.

4) Pod System

A pod system is a compact, low-maintenance vaping device that fits right between a vape pen and a box mod in terms of performance and complexity. While it offers better vapour quality than a basic vape pen, it doesn’t come with the bulk or advanced settings of a full-size box mod. These devices are often referred to by different names like pod kits, pod mods, or pod pens, depending on their size and features.

At its core, a pod system is built from a few essential components. There’s an LED indicator to display battery or draw activity, a rechargeable battery that powers the device, and a power button, though some models are inhale-activated and don’t use buttons at all. Charging is handled via a micro USB port (or USB-C on newer models), keeping things fast and simple. Inside the pod, there’s a coil that heats the e-liquid, an e-liquid window to let you check your juice level, and a mouthpiece often moulded for comfort and smooth airflow. Despite the small size, some pod systems offer advanced features like wattage control or screens. Below is an image illustrating these components for better understanding.

These systems are ideal for beginners but also appeal to experienced users looking for something portable. They’re especially well-suited for mouth-to-lung (MTL) vaping. That said, some pod mods come equipped with lower-resistance coils, giving them enough kick for direct-to-lung (DTL) hits if you're chasing bigger clouds in a smaller package. In terms of design, these devices are ultra-portable, slim, and minimalistic, built for portability without compromising on vapour quality.

Pod systems come in two different types: Closed-System (Pre-Filled) Pods and Open-System (Refillable) Pods. You can go with pre-filled pods for ultimate convenience, just pop in a new pod and toss the old one, no mess, no refills. This is great for smokers transitioning to vaping or anyone who hates dealing with e-liquid bottles. On the other hand, refillable pod systems offer more freedom and long-term savings. You can use your own choice of e-liquids and refill the pod when it runs low. Some devices even let you swap between pre-filled and refillable pods, giving you the best of both worlds.

5) Box Mods

A box mod is a high-performance vaping device built for vapers who want more power, control, and customisation from their vape. It gets its name from its bulky, rectangular shape, and is known for offering advanced features not typically found in smaller devices. Also called box vapes, box kits, mech mods, or mechanical mods, these devices are popular with experienced users who want to fine-tune their vaping style, produce massive clouds, or simply enjoy a more tailored experience.

Box mods are built with a display screen, LED or OLED, which shows key data like wattage, battery level, coil resistance, and temperature. The battery can be built-in or removable, usually powerful enough to last all day or support extended vaping sessions. A power button turns the device on and activates it when pressed. The USB-C charging port is used to recharge the device or upgrade firmware. Internally, the coil heats the e-liquid and is part of the tank system, which includes an e-liquid window to check juice levels and a mouthpiece for inhaling vapour. For precision, box mods usually come with separate increase and decrease wattage buttons, letting you adjust power output to match your preferences or your coil's specifications. Refer to the succeeding image for a visual representation of these components in a box mod.

These vape mods are best suited for advanced users who value customisation and support sub-ohm vaping, which uses coils with less than 1.0 ohm of resistance. This allows the coil to heat faster and produce more vapour, delivering dense clouds and rich flavour. Sub-ohm setups are perfect for direct-to-lung (DTL) vaping and are a favourite among cloud chasers. On the other hand, with a higher-resistance coil and lower power setting, box mods can still support mouth-to-lung (MTL) vaping, giving them flexibility.

Box mods offer a wide range of features like adjustable wattage (often from 50W to over 200W), temperature control for better coil performance, and compatibility with sub-ohm tanks. Sub-ohm vaping lets you vape at higher wattages to produce thicker vapour and richer flavour. These mods also support various tank types, including rebuildable dripping atomisers (RDAs), rebuildable tank atomisers (RTAs), and sub-ohm tanks. Most models use external batteries such as 18650s or 21700s, which can be swapped out to keep vaping all day.

Unlike pod systems that use pre-filled or refillable pods, box mods work with tanks that are always refillable, offering complete freedom over e-liquid choice and coil changes. The refillable nature is ideal for users who want to experiment with different flavours or coil setups.

6) MTL (Mouth-To-Lung) Vape Kits

MTL vape kits are devices offering a slower, more deliberate vaping experience that closely mimics the sensation of smoking a traditional cigarette. The term “MTL” stands for mouth-to-lung, which describes the way vapour is drawn into the mouth first and then inhaled into the lungs. This style delivers a tighter, smoother draw with less vapour, making it a great fit for users who are either transitioning from smoking or simply prefer a low-key, flavour-focused session. MTL vapes are also referred to as MTL kits, MTL devices, or mouth-to-lung pod systems, and they typically prioritise nicotine satisfaction and taste over cloud production. Below is an image illustrating the MTL inhalation technique for better understanding.

These devices are most suitable for beginners, casual vapers, or anyone looking to replicate the feel of smoking. They're perfect for high-nicotine or nicotine salt e-liquids and often work well at lower wattages. MTL vaping offers a discreet experience that doesn’t fill a room with vapour, making it ideal for use in public or on the go. The draw is tighter and more controlled, with an emphasis on throat hit rather than big clouds.

The design of MTL vapes tends to be sleek and compact. They’re often lightweight and pocket-friendly, with an intuitive setup that doesn’t require much tinkering. Whether in the form of slim pod systems, pen-style vapes, or smaller box-style kits, MTL devices usually come with a modest power output, long battery life, and minimal maintenance requirements. Features may include a simple power button, auto-draw activation, LED indicators for battery level, and compatibility with higher-resistance coils for a cooler, smoother vape.

Many MTL vape kits use pod-based systems, which can be either prefilled or refillable. Prefilled pod vapes come with e-liquid already sealed inside, and you simply replace the entire pod when it’s empty. On the other hand, refillable MTL pods let users fill their own e-liquid, which offers more flexibility with flavours and nicotine strength while being more economical over time. Whether you're after a quick plug-and-play option or something you can customise to your taste, MTL vapes are a reliable, no-fuss solution for a satisfying and cigarette-like vaping experience.

7) DTL (Direct-To-Lung) Vape Kits

DTL vape kits are devices built for vapers who want bigger clouds, bolder flavour, and a more immersive inhale. Instead of holding the vapour in the mouth first, you draw it straight into the lungs, hence the name “direct-to-lung.” This style is all about intensity, offering a sensation closer to taking a deep breath rather than a short puff. These kits are often called sub-ohm vapes, cloud kits, DTL pod mods, or direct-lung vape systems, and they’re designed to deliver high power and serious vapour. Refer to the following image for a visual representation of the DTL inhalation method.

DTL kits are best suited for intermediate to advanced users who enjoy cloud chasing or want maximum flavour from their e-liquids. They’re not ideal for beginners or smokers trying to replicate the feeling of a cigarette. The inhale is smooth and deep, and it usually works best with low nicotine strengths to avoid a harsh throat hit. High-VG e-liquids are commonly used in these devices because they produce thicker vapour and a softer inhale, which pairs perfectly with the open airflow and higher wattage typical of DTL setups.

DTL vape kits are usually larger and more robust than MTL devices. They may come in the form of box mods, large pod mod devices, or full vape kits with external batteries. Many DTL devices feature a large display screen to show wattage, battery life, and coil resistance, along with buttons to adjust settings. You’ll also find wide drip tips for smoother airflow, adjustable airflow rings, and sub-ohm tanks or pods that support low-resistance coils. These devices focus on performance and customisation, giving users the freedom to fine-tune their vape exactly how they like it.

DTL pod kits can use either prefilled pods or refillable pods, but refillables are far more common in this category. Prefilled pods don’t really suit the high-wattage, high-VG setup that DTL vaping demands, because they're usually built for MTL systems and thinner liquids. Refillable pods, on the other hand, let users load up their favourite thick e-liquids, switch coils as needed, and enjoy full control over their vape.

How To Choose The Right Vape For You?

Choosing the right vape kit isn’t just about picking the flashiest device or the one with the most buttons; it’s about matching your vaping needs to the right setup, so your experience is satisfying from the first puff to the last. The perfect vape kit depends on a few core factors: your preferred vaping style, nicotine needs, and the type of e-liquid you plan to use.

1. Identify Your Vaping Style

The first step in choosing a vape is determining how you prefer to inhale vapour.

• Mouth-To-Lung (MTL) Vaping – Best for smokers transitioning to vaping, as it replicates the sensation of smoking a cigarette. It requires higher nicotine e-liquids (nic salts or high-PG).

• Direct-To-Lung (DTL) Vaping – Ideal for those who prefer large clouds and smooth throat hits. Works best with low-nicotine, high-VG e-liquids.

• Restricted Direct-To-Lung (RDTL) Vaping – A hybrid style that balances vapour production and throat hit. Suitable for mid-range wattage devices.

Understanding your vaping style helps in narrowing down the best vape devices.

2. Choose the Right Type of Vape Device

Each vape device caters to different needs, from beginner-friendly options to advanced setups.

• Cigalikes – Resemble traditional cigarettes and are the easiest to use. Best for beginners who want a no-maintenance option.

• Vape Pens – Slim, refillable, and offer more control over e-liquid choices. A great middle ground between simplicity and flexibility.

• Pod Vape Kits – Available in prefilled and refillable versions, providing a balance of convenience and performance. Ideal for nicotine salt e-liquids.

• Vape Mods & Box Mods – High-powered devices with adjustable settings, making them perfect for customisation and cloud production.

• Sub-Ohm Kits – Built for DTL vaping, delivering intense flavour and massive vapour clouds. Best for experienced vapers.

Selecting the right device depends on how much control, portability, and vapour production you prefer.

3. Consider E-Liquid Compatibility

Not all vape devices work with every type of e-liquid. Matching the right e-liquid to your device ensures optimal performance and satisfaction.

• High-PG E-Liquids & Nic Salts – Best for MTL vapes like cigalikes, vape pens, and pod systems. Offer a stronger throat hit and faster nicotine absorption.

• High-VG E-Liquids – Designed for sub-ohm kits, vape mods, and box mods. Produce large vapour clouds with a smoother inhale.

• 50/50 E-Liquids – Work well with both MTL and RDTL devices, offering a balance of flavour and vapour production.

Choosing an e-liquid based on nicotine strength, VG/PG ratio, and flavour preference ensures the best experience.

4. Battery Life & Charging Convenience

Battery life plays a crucial role in daily vaping convenience, especially for heavy vapers.

• Built-in Batteries – Found in cigalikes, vape pens, and pod kits. Offer easy charging but have limited lifespan.

• Removable Batteries – Common in box mods and high-powered vape mods. Allow for extended use by swapping batteries.

• Fast Charging – Devices with USB-C charging provide quicker recharges for on-the-go convenience.

Choosing a device with the right battery capacity ensures uninterrupted vaping.

5. Portability & Ease of Use

Your lifestyle determines whether a compact, pocket-friendly vape or a high-performance device suits you best.

• Travel-Friendly – Cigalikes, disposable vapes, and compact pod systems are ideal for vapers who need something discreet and lightweight.

• Customisation & Power – Advanced vapers who prefer adjustable wattage, airflow control, and large e-liquid capacity benefit from box mods and sub-ohm kits.

Selecting a vape based on portability ensures it aligns with your daily routine and vaping habits.

6. Maintenance & Coil Replacement

Different vape devices require different levels of maintenance.

• Prefilled Pod Kits & Disposable Vapes – Zero maintenance, just replace when empty.

• Refillable Pod Kits & Vape Pens – Require coil or pod replacements but are easy to maintain.

• Sub-Ohm Tanks & Mods – Need regular coil changes, tank cleaning, and battery care, but offer the most control.

The best vape is one that matches your vaping style, nicotine preference, and lifestyle needs. Whether you’re looking for a simple MTL device for smooth nicotine delivery or a powerful sub-ohm kit for cloud chasing, selecting the right vape ensures an enjoyable experience.

What Are The Most Popular Vape Brands In The UK?

Some of the most popular vape brands in the UK include Elf Bar, IVG, Vaporesso, Smok, Oxva, Aspire, Lost Mary, Uwell, and Innokin. These vape brands are known for their wide range of reliable vape kits, disposable vapes, and innovative pod systems. Whether you're into cloud-chasing sub-ohm devices or looking for beginner-friendly disposables, these names dominate the UK market. Here’s a quick look at some of the vape brands and their standout products:

How To Choose The Right Vape Juice For Your Device?

Choosing the right vape juice or eliquid for your device is the difference between a smooth, flavourful hit and a burnt, gurgling mess. Not all e-liquids are created equal, and not every device can handle every type. The trick is understanding how the VG/PG ratio, nicotine strength, and flavour type pair with your setup. One wrong move and you’re either flooding your coil or choking on harsh throat hits.

Start with the VG/PG ratio. VG (Vegetable Glycerin) is thick and makes big clouds. PG (Propylene Glycol) is thinner, carries flavour better, and gives a stronger throat hit. If you’re using a sub-ohm or DTL (Direct-to-Lung) vape kit, high-VG e-liquids (usually 70/30 VG/PG or higher) are your best bet. These kits have the power and airflow to handle thicker juice and produce massive vapour without choking your coil. For MTL (Mouth-to-Lung) kits, pod systems, or vape pens, you’ll want high-PG or balanced 50/50 e-liquids. These thinner liquids wick easily in low-power devices and deliver sharper throat hits. Use high-VG juice in a pod kit, and you’ll get dry hits, spitback, and probably ruin your coil in record time. The succeeding image is for your better understanding of a VG/PG ratio and its suitable device.

Next, check the nicotine strength and type. Nic salts are smoother and absorb faster, perfect for low-wattage MTL devices and new vapers who want a satisfying hit without the harshness. They usually come in 10mg or 20mg strengths in the UK. Avoid using nic salts in sub-ohm devices. Freebase nicotine comes in lower strengths (3mg to 12mg) and works better in high-powered devices. It gives a stronger throat hit and slower nicotine delivery, which suits DTL vapers and cloud chasers. Refer to the upcoming image for a clear guide on nicotine strengths associated with each smoker experience, alongside the equivalent number of cigarettes they represent for various smoking experiences.

Flavour matters too, but not just for taste. Dessert and creamy flavours tend to work better with sub-ohm setups because high VG blends make the richness pop. Fruity and minty flavours often shine in MTL devices, where sharper PG levels amplify the taste. Some flavours, like overly sweet or dark juices, can gunk up coils quickly, especially in smaller pod systems. So if you’re burning through coils too fast, your flavour choice might be the villain. Below is an image illustrating these vape juice flavours for better understanding.
