Mod Vapes

What Are Mod Vapes?

A mod vape is a reusable, rechargeable vaping device built around a battery and a control board, designed to be paired with a separate tank, pod or atomiser. The word 'mod' comes from the early days of vaping, when hobbyists modified torches and flashlight tubes to power coils. Today the term covers a wide family of devices, from slim pocket-sized pod mods to full-size box mods that take two removable batteries. What they share is flexibility: you choose the power output, the coil, the tank and the e-liquid, rather than being locked into whatever a sealed device happens to contain.

At the heart of every modern mod is a chipset. This regulates how much power reaches the coil, protects against short circuits and overheating, and lets you adjust output in watts. Many chipsets also offer temperature control, bypass or pulse modes, and a screen that shows wattage, battery level, coil resistance and puff counts. Basic units skip most of this and give you a single fire button with a handful of fixed power levels, which is perfectly adequate if you only want something simple.

The mod collection on this page covers the main formats currently sold in the UK: box mods with removable batteries, all-in-one pod mods with built-in batteries, kits that bundle a mod with a matching tank and spare coils, and standalone mods for people who already own tanks they like. Because the device is only one half of the setup, it is worth thinking about the whole system: battery, tank, coil and liquid all affect the vape you end up with.

It is also worth being clear about what mods are not. They are not disposable. A decent mod should last years with ordinary care, and the running costs come from coils, e-liquid and the occasional battery or tank replacement. That makes them a very different proposition from a single-use product, both in how you use them and in how you look after them.

Types of Mod: Box Mods, Pod Mods, Squonk Mods and Mechanical Mods

Not every mod works the same way, and picking the right format matters more than picking the right brand. Here is how the main types differ in practice.

• Box mods. Rectangular devices, usually taking one, two or three removable 18650 or 21700 cells. They offer the highest wattage ranges, often well beyond 100W on dual-battery models, and pair with sub-ohm tanks for large clouds and rich flavour. They are bigger and heavier than other formats, which is the trade-off for longer battery life and more power.
• Pod mods. Compact devices that use a refillable pod with a coil built into the cartridge. Many have an integrated battery, USB-C charging and adjustable airflow. Output is typically in the 15W to 40W range, which suits mouth-to-lung vaping and nicotine salt e-liquids. Larger pod mods push higher, with some reaching around 80W for sub-ohm pods.
• Squonk mods. Box mods with a squeezable bottle built into the body. You press the bottle to feed e-liquid up to a squonk-compatible atomiser, so you do not have to unscrew the tank to refill. They are popular with people who vape often and like to keep the atomiser fresh, though the learning curve is steeper than with a standard tank.
• Mechanical mods. Unregulated tubes or boxes with no chipset, where battery output goes straight to the coil. They suit experienced users who understand Ohm's law and battery safety. For anyone new to vaping, a regulated mod is the sensible choice, because the safety protections are built in.
• Starter kits with mod-style bodies. Often sold as a mod plus tank in one box, with coils included. This is the easiest way into the category because everything is matched by the manufacturer.

If you are unsure, the usual rule of thumb is simple: choose a pod mod for convenience and nicotine salts, choose a regulated box mod for power and flexibility, and leave mechanical and squonk setups until you are comfortable with the basics.

Who Mod Vapes Suit

Mods suit a broad range of UK vapers, but the reasons people buy them differ quite a lot.

Former smokers moving off disposables. Since single-use vapes were banned from sale across the UK in June 2025, many people who relied on disposables have had to find a reusable alternative. A pod mod with a similar draw and a nicotine salt liquid is the closest match to the old experience, and it works out considerably cheaper over a few months than buying devices repeatedly. A starter-friendly pod mod is usually the right entry point rather than a high-power box mod.

Experienced vapers who want control. If you already know whether you prefer a tight draw or an open one, a high-wattage or adjustable mod lets you tune airflow, power and coil type to your taste. This group tends to enjoy swapping tanks and trying different coils to fine-tune flavour and vapour production.

Heavy daily vapers. Battery life is a real practical concern if you vape throughout the day. Removable cells on a box mod can be swapped in seconds and charged outside the device, so you are never waiting on a charging cable. Large integrated-battery pod mods also help, particularly those with 2,000mAh or more.

Flavour chasers. Sub-ohm mod setups tend to produce fuller, cooler flavour than small pod systems, especially with mesh coils. If you enjoy dessert, fruit or menthol profiles and want them to show clearly, a mod with a good tank can deliver that.

People who want to save money. The upfront cost is higher than a single pack of cheap pods, but a mod used with coils and bottled e-liquid is typically less expensive per day than repeatedly buying sealed devices.

Mods are less suited to people who want the absolute minimum of fuss. If you would rather never refill, change a coil or charge a battery on a schedule, a closed pod system may be easier. Everything on this page is for adults aged 18 and over, and it is intended for existing smokers or vapers rather than people who have never used nicotine.

How to Choose a Mod: Wattage, Battery and Size

Three specifications do most of the work when you compare mods: power output, battery arrangement and physical size.

Wattage range. This tells you how much power the device can send to the coil. A compact pod mod that tops out at 25W to 40W is designed for tight, cigarette-like inhales. A mid-range box mod with a maximum around 80W to 100W covers most sub-ohm and mesh coil setups. Dual-battery devices that go beyond 200W exist, but most everyday vapers will rarely use more than 60W to 80W. Buying far more power than you need only means a bigger, heavier device and faster battery drain.

Battery type. Integrated batteries are sealed in the body and charged by USB-C. They keep the device slim and simple, but when the battery eventually fades the whole device has to be replaced or repaired. Removable 18650 and 21700 cells can be swapped and replaced individually. A 21700 cell generally holds more capacity than an 18650, which translates into longer vaping between charges. If you choose a removable-battery mod, buy cells from a reputable supplier and check the continuous discharge rating suits the wattage you plan to use.

Size and weight. A dual-battery box mod is noticeably bulky in a jacket pocket. A single-battery mod or an integrated pod mod is lighter and more discreet. Think about whether you are carrying it all day or mostly vaping at home.

Chipset and features. Look for basic protections such as short-circuit, over-discharge, low-resistance and over-temperature cut-offs. Beyond that, features such as a clear screen, a lock mode to stop accidental firing and fast charging are useful rather than essential.

Tank compatibility. Most box mods use a standard 510 thread connection, so you can fit tanks from different manufacturers. Pod mods usually only work with their own proprietary pods, so check which pod series a device takes before you buy spare coils. For UK purchases, remember that tank capacity is capped at 2ml, which is a legal limit rather than a design choice.

A good approach is to decide how you want to vape first, then pick a mod that sits comfortably within that range rather than at the very top of it.

Tanks, Coils and E-Liquid: Flavour and Strength Considerations

A mod is only as good as what you pair with it. The right coil and liquid combination often makes a bigger difference than the device itself.

Coil resistance and type. Sub-ohm coils sit below 1.0 ohm, with common values between about 0.15 and 0.6 ohm, and are designed for direct-to-lung inhaling, where you draw straight into the lungs. They produce more vapour and tend to make flavour more prominent. Coils at roughly 0.8 to 1.2 ohm suit mouth-to-lung vaping, which feels closer to smoking a cigarette. Mesh coils spread heat evenly across a flat surface and usually give a quicker ramp-up and consistent flavour. Traditional wire coils are cheaper and still widely available.

Matching liquid to setup. Sub-ohm tanks work best with high-VG e-liquids, typically 70% VG or more, because thicker liquid wicks well and produces dense vapour. Thinner, higher-PG liquids can leak or gurgle in sub-ohm tanks, and are better suited to mouth-to-lung pods. Nicotine salt liquids are normally sold at 10mg or 20mg and used in pod mods at lower power. Freebase nicotine liquids are usually 0mg to 6mg in sub-ohm setups, since larger vapour clouds deliver more nicotine per puff.

Nicotine strength. UK rules cap nicotine e-liquid at 20mg/ml, and that same ceiling applies to nicotine in vape devices generally. If you are stepping down from a disposable that used 20mg, a 10mg or 20mg nicotine salt in a pod mod is a sensible starting point. If you are moving to a sub-ohm setup, begin low, around 3mg, because the extra vapour makes higher strengths feel harsh. Many people reduce strength gradually over time, but there is no single correct level.

Shortfills and nic shots. Larger 50ml and 100ml shortfill bottles are sold with space left for a 10ml nicotine shot. They are cost-efficient if you vape through a lot of liquid, but you will need to mix them yourself. If you prefer simplicity, pre-mixed 10ml nicotine e-liquids are a better fit.

Flavour. Fruit and menthol profiles tend to come through well on sub-ohm mesh coils. Rich dessert and tobacco flavours work nicely at moderate wattage. If a flavour tastes muted, try a slightly higher wattage within the coil's recommended range; if it tastes burnt, drop the power.

Comparing Popular Brands and Formats

The mod market in the UK is dominated by a handful of established manufacturers, each with a recognisable character. These are general impressions rather than rankings, and individual models vary.

• Vaporesso. Known for its GTX and XROS lines. The XROS pod mods are compact and aimed at straightforward mouth-to-lung vaping, while the GTX and Target series cover higher power with proprietary coils.
• Voopoo. Makes the Drag series of box mods and the Vinci pod mods. The Drag range uses the GENE chipset and is popular for its reliable build and wide coil compatibility.
• Geekvape. Offers the Aegis range, which is built to resist drops, dust and water, and is often chosen by people who want a hard-wearing device. Also produces the Wenax pod series.
• SMOK. One of the longest-running names, with a large catalogue including the Novo pod range and the Nord series, which is familiar to many UK vapers.
• Uwell. Best known for the Caliburn pod systems. These are small and simple, favoured by people who want a tidy pod device without a lot of settings.
• Freemax, Aspire, Innokin and Lost Vape. Established names with a variety of tanks, pods and box mods, from entry-level options to more refined builds.

Choosing between formats. A pod mod gives you easy refills, light weight and decent flavour at modest power. A box mod gives you broader choice of tank, longer battery life and more headroom. Kits sit in between, offering a ready-to-use bundle at a clear price. If you already own tanks and batteries, buying a standalone mod can be more economical than a full kit.

Replacement parts. Before committing, check how easy it is to find coils and pods for a device in the UK. A mod that is stylish but has scarce replacement coils quickly becomes frustrating. Mainstream brands generally have coils and pods stocked widely, which is worth weighing against any slightly lower price on a lesser-known alternative.

UK Legal Context: Limits and Rules for Mods and E-Liquids

Mod vapes are sold under the UK's regulations for nicotine-containing products, and several rules shape what you will see on the shelf.

• Nicotine cap. Nicotine e-liquid and vape products are limited to 20mg/ml (2%). That is the same cap that applied to the disposable devices which are now banned, so a 20mg nicotine salt remains the strongest legally sold option.
• Tank size. Refillable tanks and pods are limited to 2ml in capacity. Some tanks ship with a larger glass section for other markets, but the tank fitted to UK stock holds 2ml.
• Bottle size. Nicotine-containing e-liquid is limited to 10ml bottles. Larger shortfill bottles contain 0mg nicotine and are sold with separate nicotine shots.
• Age restriction. It is illegal to sell vaping products, including mods, tanks and e-liquid, to anyone under 18, and it is illegal for adults to buy them on behalf of under-18s.
• Single-use ban. Disposable vapes have been banned from sale across the UK since June 2025. Mods, pod systems with replaceable parts and refillable kits remain legal, because they are rechargeable and reusable.
• Labelling. Products must carry health warnings and ingredient information, and notified products carry a child-resistant, tamper-evident design on refill containers.

Rules can change, and the details differ slightly between products, so it is sensible to read the packaging and the product page. If a product is advertised with a nicotine strength above 20mg/ml, a tank claiming a larger capacity than 2ml, or a bottle bigger than 10ml of nicotine liquid, treat it with suspicion, because it is unlikely to be intended for the UK market.

Battery Safety, Care and Maintenance

Mods are safe when used sensibly, and almost every incident involving batteries traces back to avoidable mistakes. A few habits keep you well within safe territory.

Batteries. If your mod uses removable cells, use only cells meant for vaping, from a reputable source, and check each one for tears or damage in the wrap before you insert it. Do not mix old and new cells, or cells from different brands, in a dual-battery mod. Carry spare cells in a plastic case rather than loose in a pocket or bag where they could touch coins or keys. For integrated batteries, use the cable supplied or a quality USB-C cable, and avoid leaving the device charging unattended overnight.

Charging. A standalone external charger is gentler on removable cells than charging them inside the device, and it lets you charge two cells at once. Unplug once the cell is full.

Coil care. Prime a new coil by saturating the wicking holes with e-liquid and leaving it to soak for several minutes before firing. This single step prevents the dry, burnt taste that makes people think a coil has failed. Replace coils when flavour fades or the vapour thins, which for most users is every one to three weeks depending on how heavily they vape and how sweet the liquid is.

Cleaning. Every few weeks, rinse the tank with warm water, dry it fully and wipe the battery contacts and 510 connector with a dry cloth. Residue on the contacts can cause misfires.

Storage. Keep your mod out of direct sunlight and away from hot cars. Extreme temperatures degrade batteries and can cause leaking.

Recycling. Never put vapes or loose batteries in household bin or kerbside recycling, because crushed lithium cells can cause fires in collection vehicles and recycling plants. Removable 18650 and 21700 cells can go into the battery recycling bins found in most large supermarkets. Complete devices and pods should be taken to a household waste recycling centre or to a shop that offers vape and small electrical recycling drop-off points. Many UK vape shops and electrical retailers take back used devices, and the Recycle Your Electricals online locator can show your nearest option.

Moving From Disposables to a Mod

The switch from a single-use device to a mod feels different at first, but a few adjustments make it smoother.

Start with a pod mod. If you were vaping a 20mg salt disposable, a pod mod filled with a 10mg or 20mg salt liquid will feel familiar. Both use a mouth-to-lung inhale, with a snug draw and a light throat hit.

Expect to refill. Pods hold up to 2ml, so you will top up several times a day if you are a heavy user. Keep a bottle with you, and refill before the pod runs low rather than letting the coil run dry.

Do not copy puff counts. Disposables were marketed on puff counts such as 600 or 3,000 puffs, which were rough estimates. With a mod, think in coils and bottles instead. A 10ml bottle will typically last a moderate vaper several days, and a coil will last one to three weeks.

Compare costs honestly. A mod costs more upfront, but the running cost is often a fraction of repeat disposable purchases. Over a month, bottled e-liquid and a couple of coils usually work out far cheaper than the same nicotine delivered through sealed devices.

Choose power gently. It is tempting to buy the highest-wattage box mod available, but a new switcher usually needs far less. Begin with a pod mod at 15W to 25W, and move up to a box mod and sub-ohm tank only once you know you want bigger vapour.

Keep your goal in mind. If you are using a mod to move away from smoking, give yourself a few weeks to adjust. Some people find it takes a few attempts with different nicotine strengths and flavours before the setup feels right.

Buying Tips: Value, Authenticity, Warranty and Returns

Mods vary a lot in price, and the most expensive option is not always the right one. Entry-level pod mods are inexpensive and perfectly capable. Mid-range box mods cost noticeably more, and flagship dual-battery models with large screens sit at the upper end. Kits that include a tank and spare coils often represent better value than buying the pieces separately, because the coils are the part you will use up fastest.

Check what is in the box. Some kits include batteries, others do not, and removable-battery mods are rarely sold with cells because of shipping rules. Look for a USB-C cable, spare coils or pods, a manual and a warranty card.

Spotting genuine stock. Counterfeit mods exist, particularly for well-known brands. Warning signs include unusually low prices, poor print quality on packaging, spelling mistakes in the manual, missing batch or authentication codes, and loose or rough fittings on the device. Many manufacturers use a scratch-off or scannable code that you can verify on the official brand website. Buy from a reputable UK retailer that sources directly from distributors, rather than from unverified marketplace sellers.

Warranty. Reputable manufacturers typically cover mods against manufacturing faults for a limited period, often several months, although the exact term varies by brand and product. Warranty usually does not cover glass tanks, coils, batteries, cosmetic wear or damage from drops, liquid or misuse. Keep your receipt and the packaging, and register the warranty if the brand offers it.

Returns. Because vaping products are consumables as well as devices, retailers often cannot accept returns on opened coils, pods or e-liquid for hygiene reasons. If your device arrives faulty, contact the seller promptly with photos and your order number.

Delivery. UK orders require an adult to confirm they are 18 or over, and some couriers ask for ID at the door. Choose a delivery option that suits your schedule, and check that the address on the order is correct, because age-restricted parcels cannot usually be left unattended.

Honest value check. Before you buy, work out the realistic cost of the full setup: device, spare coils, e-liquid and, if needed, batteries and a charger. That total, rather than the headline price of the mod alone, tells you whether a particular device suits your budget.
