A GUIDE TO E CIGARETTES RECHARGEABLE

Key Takeaways

• Cost-Effective and Sustainable – Rechargeable E-Cigarettes save money over time and reduce waste compared to disposables.

• Customisable Vaping Experience – Users can choose their preferred e-liquids, nicotine strengths, and flavours for a more tailored experience.

• Internal and External Batteries - Prefilled devices often utilise a housing for an internal battery, where more complex vapes use changeable batteries such as the 18650.

If you’re looking into vaping, you’ll quickly notice that rechargeable e-cigarettes are a hugely popular choice, especially for people moving away from traditional tobacco. These individuals, often referred to as vapers, use these devices as a long-term investment in their vaping journey. Unlike single-use disposables that you toss after they’re done, these devices can be used over and over again. You simply recharge the battery and refill or replace the e-liquid component.

This reusability is what makes them a smart, sustainable, and cost-effective way to vape, giving you far more control and value in the long run. However, it's important to note that usage patterns—such as how frequently you vape and how you maintain your device—can significantly impact the longevity and overall value of rechargeable e-cigarettes.

The reduced waste and concerns about disposable vapes getting into the hands of underage teens are the main reasons why disposable vapes are now banned in the UK. (1)

Why Choose Rechargeable E-Cigarettes

Stepping into the world of vaping can feel a bit daunting at first, but choosing a rechargeable model makes the whole process much more rewarding. It’s a bit like swapping a disposable coffee cup for a proper reusable travel mug. Yes, the initial purchase might be a touch more, but the long-term benefits are massive—you save money, it's better for the environment, and you get a much more personalised experience - you can even get emotionally attached to your coffee cup!

This shift towards rechargeable vape kits is a big reason why the UK e-cigarette market is projected to grow by USD 1.47 billion between 2025 and 2029 (2). Once you understand how these devices work, it all clicks into place, and you can feel confident you're making the right choice. At their heart, they're made of three main parts that work together to create that smooth vapour.

The Core Components

• The Battery: This is the engine of your E-Cigarette. It's the rechargeable powerhouse that provides the energy to heat up the e-liquid.

• The E-Liquid Chamber: You'll see this called a tank, pod, or cartomiser. It's simply the part that holds your chosen vape juice flavour and nicotine strength. Many modern devices use replaceable pods, making it easy to switch flavours or maintain your device with minimal hassle. 

• The Atomiser: This is the clever bit—the heating element, or coil. When you activate the battery, the atomiser gets to work, gently heating the e-liquid and turning it into the vapour you inhale. This can be in the prefilled refill or below the tank on a refillable device.

Getting to grips with these basic parts puts you in the driver's seat. You can start exploring different e-liquids, learn how to look after your device for the best performance, and enjoy a far more consistent and reliable vape than you'd get from disposables or traditional cigarettes.

Making the switch is a genuinely empowering step. If you're just starting out, our comprehensive beginner's guide to e-cigarettes can walk you through everything you need to know. A little bit of knowledge upfront makes all the difference in choosing a device that slots perfectly into your life.

How Do Rechargeable E-Cigarettes Actually Work?

To really get what makes rechargeable vape kits tick, it helps to look under the bonnet. At its heart, the whole thing is a simple, elegant process powered by a few key parts working together perfectly.

It all starts with the battery. Think of it as the heart of your device, holding and sending out the energy needed for everything else to happen. When you press the button—or on some models, just take a puff—you're telling that power source to get to work.

This sends an electrical current from the battery to a tiny but crucial component called the atomiser, or coil. The atomiser is the real engine room of your vape. For a simple analogy, picture it as a miniature electric kettle.

Just like a kettle’s element heats water, the atomiser’s coil gets hot almost instantly when the current flows through it. This coil is wrapped around a wicking material—usually organic cotton—that has soaked up the e-liquid from your tank or pod. As the coil heats up, it vaporises the e-liquid. Inhaling is the key step that draws this vapour into your mouth or lungs, closely mimicking the experience of traditional smoking.

From Liquid to Vapour

That intense, rapid heat from the coil causes the e-liquid in the wick to vaporise in a split second. It goes from a liquid to an aerosol, or vapour, which you then inhale. This entire process happens almost instantaneously from the moment you fire up your device.

This basic mechanism is the same across all types of e cigarettes, though the specifics can change a bit:

• Pod Systems: These are built for pure simplicity. The atomiser is tucked away inside a disposable or refillable pod, so maintenance is as easy as just swapping the pod out.

• Vape Pens: A classic design where the atomiser coil is a replaceable part inside a tank. They offer a great balance between ease of use and a bit of customisation.

• Mod Kits: These are more powerful bits of kit that give you greater control over the power output. This directly affects how hot the coil gets and, in turn, how much vapour you get.

No matter the model, the principle is always the same: a battery heats a coil, and that coil vaporises the e-liquid. Grasping this simple process helps you use your device properly and even sort out minor issues with confidence.

The Role of the Battery

Vape batteries do more than just supply power; its capacity and output shape your whole vaping experience. Modern vape kits often use rechargeable batteries, offering greater convenience and sustainability—especially in prefilled pod kits—by enabling extended use and reducing waste. Measured in milliampere-hours (mAh), a higher number generally means you can go longer between charges. (3)

Rechargeable vs Disposable Vapes: A Comparison

Sooner or later, every vaper finds themselves at a crossroads: stick with the convenience of disposables or make the leap to a rechargeable device. A disposable vape offers simplicity and ease of use, making it a popular choice for beginners. Disposables are undeniably handy, especially when you’re just starting out. But when you put them head-to-head, it becomes clear why E-Cigarettes' rechargeable models are the smarter choice for the long haul.

It really comes down to what you’re looking for in your vaping experience.

With rechargeable vapes, you can reuse the same device multiple times, making them more cost-effective and environmentally friendly in the long run. It costs a bit more upfront, but it pays for itself over and over again, all while giving you a much better brew.

Let’s break down the differences that really matter.

Cost and Environmental Impact

The biggest difference you'll notice is in your wallet. A daily disposable habit adds up, and it adds up fast. For someone spending £5 a day on disposables, switching to a rechargeable vape kit and buying e-liquid could save them over £1,500 in a single year. That's a serious saving. 

Buying e-liquid or pods in a pack or choosing offers that bundle multiple boxes and accessories together can offer even more savings and convenience.

Then there's the environmental side of things. Disposables are a real problem for electronic waste, with their single-use batteries and plastic shells piling up in landfills. A single rechargeable device, used for a year or more, can replace hundreds of disposables. It’s a simple switch that massively cuts down your environmental footprint.

Performance and Customisation

This is where rechargeable devices truly pull ahead. They are built for a consistent, reliable experience. One of the key advantages is their far superior battery capacity, measured in milliampere-hours (mAh). A higher mAh rating means more vaping time between charges.

However, it’s not just about power. Rechargeables unlock a whole world of choice. You’re no longer stuck with the limited, pre-filled options on the shelf. You can explore thousands of e-liquid flavours and dial in your perfect nicotine strength, whether you need a higher level to switch from smoking or want to taper down to zero nicotine.

With refillable options, you could make your own e-liquids, allowing you to adjust flavour intensity, create very specific nicotine strengths, and tailor your vaping experience to your individual preferences. That kind of control is what makes vaping a truly personal journey.

To help you weigh your options, here’s a straightforward comparison:

Rechargeable E-Cigarettes vs Disposable Vapes

Ultimately, disposables have their place. They're great for someone curious to try vaping without commitment but, for anyone looking to vape regularly, a rechargeable model offers a richer, more economical, and far more satisfying experience. If you want to learn a bit more about the single-use option, have a look at our guide on what disposable vapes are and why they are popular.

Choosing Your First Rechargeable E-Cigarette

Finding the right rechargeable vape kit shouldn’t feel like a chore. With so many options out there, the trick is to focus on what actually matters to you. The goal is to pick a device you’ll genuinely enjoy using from the very first puff. Different devices are designed to cater to the needs and preferences of various users, ensuring everyone can find an option that suits their style and habits.

Let’s cut through the noise and look at the most popular types of rechargeable vape devices you’ll find here in the UK. Each one is designed for a slightly different experience, making it easier than you think to find your perfect match.

Understanding the Main Device Types

Thinking about your daily routine and what you really want from vaping will point you in the right direction. Are you after pure simplicity, or do you fancy a bit more control?

The UK vaping scene is incredibly diverse, which just goes to show there's a device out there for everyone. In fact, it's expected that by 2025, around 10.4% of UK adults will be using e-cigarettes—that's about 5.5 million people. Of these, 33% are current smokers and 18% are ex-smokers, highlighting the role these devices play in moving away from tobacco. You can read the full report on UK vaping demographics from Hangsen for all the details.

Key Questions to Ask Yourself

Before you pull the trigger, take a moment to consider what you really need from your device. Answering these simple questions will bring a lot of clarity and help you choose with confidence.

Your ideal device is one that fits seamlessly into your life. Don't worry about getting the most advanced kit; focus on finding one that feels right for you and your personal goals.

Think about these points:

• How much battery life do I need? Think about your daily routine. If you're out all day, a device with a larger battery (like a box mod) might be a better fit than a smaller, compact pod system that needs more frequent charging. That said, SMOKO vape kits are light and compact enough that carrying two on your persons still won't take up more space than a mod vape kit.
  

• What kind of draw do I prefer? Are you looking for a tight, restricted draw that feels like a traditional cigarette? This is known as Mouth-to-Lung (MTL). Or do you prefer a looser, airier draw, called Direct-to-Lung (DTL)? Most kits aimed at beginners are designed to give a satisfying MTL experience. Most vapers tend to prefer MTL devices when starting out, as they closely mimic the sensation of smoking.
  

• How important is simplicity to me? If you just want to grab it and go without any faff, a pod system is your best bet. If you don't mind a little bit of tinkering, like changing coils, then a vape pen could be the perfect middle ground.

Mastering Battery Safety and Charging Habits

The battery is the heart of your rechargeable e-cigarette, and looking after it properly is non-negotiable for both safety and performance. Getting this right not only keeps your vape working as it should but also massively extends its lifespan, protecting your investment in the long run.

Think of it like the battery in your mobile phone; you wouldn’t dream of using a frayed, dodgy-looking cable from a brand you’ve never heard of, or leave it charging on a pile of cushions. The exact same common-sense principles apply here. Getting into good habits from day one is the easiest way to stay safe and get the most out of your device. 

Many modern vape kits now feature USB-C charging, which offers faster and more reliable charging compared to older methods, making it both convenient and efficient for users.

Smart Charging Do's and Don'ts

To keep things simple, just follow these essential golden rules. They’re dead easy to remember and make a massive difference to the long-term health of your e cigarette's rechargeable battery.

• DO use the charging cable that came in the box. It’s been made specifically to deliver the right amount of power safely.

• DO NOT leave your vape charging overnight or unattended for hours on end. Overcharging puts stress on the battery, which can shorten its life and even create a safety risk.

• DO charge it on a flat, non-flammable surface. Your desk or a kitchen counter is perfect. Avoid charging it on your bed, sofa, or anywhere near flammable materials.

• DO NOT plug it into a powerful wall adapter, like the one for your tablet or laptop. These can push too much power into the battery and cause damage. Stick to a standard 1-amp plug or a USB port on a computer.

Essential Maintenance For A Better Vaping Experience

Getting a great performance from your rechargeable e-cigarette isn’t just about what you buy; it’s about how you look after it. A little bit of regular upkeep goes a seriously long way, making sure every puff is as flavourful as the first and helping your kit last much, much longer.

For example, regularly cleaning the tank can prevent residue build-up, which helps avoid leaks, ensures a high-quality flavour experience and extends the lifespan of your device.

Think of it like owning a car. If you ignore simple tasks like changing the oil, you’ll end up with poor performance and much bigger problems down the line. The same logic applies here, but luckily, vape maintenance is far quicker and simpler!

This simple routine will keep your device in top condition, preventing common headaches like leaks or that dreaded burnt taste.

Keeping Your Tank and Coils Fresh

The most important jobs involve your tank and coil, as these are where all the magic happens. A clean tank means you get a pure flavour, and a healthy coil ensures you get that smooth, satisfying vapour you're after. Honestly, keeping on top of these two things is the secret to a consistently great vape.

Here are the key tasks to build into your routine:

1. Clean Your Tank Regularly: Whenever you switch e-liquid flavours, give your tank a quick rinse with warm water and let it air dry completely. This simple step stops old flavours from hanging around and creating an unpleasant mix. For a more thorough job, our guide on how to clean your vape tanks and coils gives you the full step-by-step process.

2. Prime New Coils: This is absolutely crucial, so don't skip it! Before you use a new coil, pop a few drops of e-liquid directly onto the cotton bits you can see. Once you've installed it and filled the tank, let it sit for 5-10 minutes to make sure the cotton is totally saturated. This prevents the coil from burning out on the first puff.

3. Know When to Change Your Coil: A coil won't last forever. You'll know it's time for a change when you get a burnt taste, the flavour seems weak or muted, or you hear a gurgling sound when you inhale.

A well-maintained device not only delivers a better experience but also saves you money. By extending the life of your coils and preventing leaks, you spend less on replacement parts and e-liquid over time.

Troubleshooting Common Annoyances

Even with perfect maintenance, you might occasionally run into a small issue like a leak or a weird gurgling or hissing sound. Don't worry, the fixes are usually very straightforward.

Gurgling sounds often means there's a bit of extra e-liquid in the coil, which you can usually clear with a sharp flick of the wrist (away from you, of course!). Leaks are often just a case of overfilling the tank or not screwing the coil in tightly enough. A quick check usually sorts it.

SMOKO Rechargeable E-Cigs and Vapes

At SMOKO, we know that quitting smoking is so important for your health and wellbeing (5). That's why making the switch to vaping needs to be as seamless as possible. The problem with bigger, more complex vapes is that they require time to get to grips with, both in terms of the spare parts and maintenance. It's something you don't want to be worrying about when you quit cigarettes. 

That's why all SMOKO starter kits use prefilled refills and inhale activation; that's as close to a real cigarette as you can get. As long as your battery is charged and you have liquid in your refill, you are good to go. They're suitable for beginner vapers and more experienced vapers looking for simplicity and ease-of-use. SMOKO vape kits are compact, light, and offer some great e-liquid flavours that are all made here in the UK, too!

Common Questions About Rechargeable E-Cigarettes

Even with all the info, it’s totally normal to still have a few questions rattling around. So, let’s tackle some of the most common queries we hear about rechargeable e-cigarettes. Getting these sorted will help you feel much more confident as you get started.

How Long Does a Rechargeable E-Cigarette Last?

The device itself, the main body of the vape, can easily last a year or even longer if you look after it. What you’ll be replacing are the parts that do all the work: the battery and the coils (or pods).

A well-maintained battery should give you several hundred charge cycles before it starts to lose its stamina, which for most people means it’ll last for many months. The coils or pods, however, are consumables. Think of them like the filter in a coffee machine – they need changing every one to two weeks, depending on how much you vape.

Is It Safe to Leave an E-Cigarette Charging Overnight?

Simply put, no. You should never leave any rechargeable electronic device charging overnight or unattended. Overcharging puts a strain on the battery, which not only shortens its overall lifespan but can also be a safety risk. The best practice is to charge your device while you're around and can keep an eye on it, unplugging it once it's full.

Most modern e cigarettes rechargeable models will fully charge in just a few hours. A good habit is to pop it on charge when you get home from work. That way, it’s all set for the evening and the next day.

Can I Use Any USB Cable to Charge My Vape?

It’s tempting to just grab the first USB cable you see, but it’s really important to use the one that came with your device. This isn't just a manufacturer's recommendation; it's about safety and performance. The supplied cable guarantees the battery gets the correct voltage and current.

Using the wrong cable, especially a high-powered one designed for a tablet or laptop, can slowly damage the battery. It might seem to work, but over time it can seriously reduce your battery's health. Stick with the original for the best and safest results.
