SMOK Infinix Pod Kit overview

The SMOK Infinix Pod Kit is a compact, refillable pod system from Smok, a hardware brand that has been making vaping devices for well over a decade. It is built for adults who want something small and simple to carry, but who would rather choose their own e-liquid, flavour and nicotine strength than buy a sealed disposable. You fill a pod, click it into the battery section, and inhale. There are no menus to learn, no wattage dials and no coil building, so the Infinix tends to appeal to people who are new to refillable vaping as well as to former disposable users looking for a tidier alternative.

The kit follows a familiar formula in the pod category. A small rechargeable battery body holds a slim refillable pod, the pod contains a coil that is already fitted, and the device fires automatically when you draw on the mouthpiece. That draw-activated design means there is no button to hold down. The Infinix sits at the pocket-friendly end of the market, so it prioritises portability and ease of use over high output or long battery endurance. If you want a device that disappears into a jeans pocket and does one job quietly, that is the territory it occupies.

This guide covers everything a UK buyer is likely to want to know before ordering: the main specifications, what to expect from puff delivery and flavour, how the battery behaves, how the coil technology works, which nicotine strength to choose, who the kit suits, how to fill and use it, how to fix common faults, and how it stacks up against rival pod kits on price and features. Where we quote figures such as battery capacity and pod size, they reflect the published manufacturer specification for this style of device. Always check the printed details on your own pack, because manufacturers revise components between production batches.

A quick note on the rules. In Great Britain, nicotine e-liquid for vaping is limited to a maximum strength of 20mg/ml (2%), refillable pods and tanks are limited to 2ml, and e-liquid bottles are limited to 10ml. The Infinix pod size sits within that framework. You must be 18 or over to buy and use any vaping product, and the single-use disposable vape ban that came into force in 2025 means refillable kits like this one are now the mainstream route for adults who want a compact, low-effort device.

Key specifications and what they mean in practice

Specification sheets can look like a wall of numbers, so here is what the main figures for the Infinix mean when you are actually holding it. The details below reflect the published specification for this type of Smok pod system. Treat them as a guide and confirm against the packaging you receive.

• Battery: a built-in rechargeable cell of roughly 250mAh. This is small by modern standards, which keeps the body slim and light, but it also means you will top it up more often than you would with a 700mAh to 1000mAh device.
• Pod capacity: 2ml, which is the maximum allowed for refillable pods in the UK. Two millilitres is enough for a full day of light to moderate use for many people.
• Coil: a pre-installed coil built into each pod, in the low-to-mid resistance range typical of mouth-to-lung pod systems, roughly 0.8 to 1.2 ohm depending on the pod.
• Activation: draw-activated, with no fire button. Breathe in and the device heats the coil.
• Charging: a USB charging port on the body, commonly USB-C on current revisions, with an LED that signals charging status.
• Inhale style: mouth-to-lung (MTL), meaning you draw into your mouth first and then inhale, similar to how you would smoke a cigarette.
• Controls: none to adjust. Output is fixed, so what you get is what the battery and coil are designed to deliver.

The 250mAh battery and 2ml pod are the two figures that shape the Infinix more than any others. A small battery supports a small, discreet body and a gentle power output, which in turn suits the lower-wattage MTL experience that nicotine-salt e-liquids work well with. The 2ml pod gives you a sensible amount of liquid without breaking the UK limit.

Because the output is fixed, you do not need to worry about wattage settings or temperature limits. The trade-off is that you cannot tune the draw if you find it too warm or too cool. Instead, you adjust the experience through your choice of e-liquid, specifically the nicotine strength and the ratio of propylene glycol (PG) to vegetable glycerine (VG). Higher PG liquids tend to flow through small coils more easily and deliver a sharper throat hit, while higher VG liquids are thicker and smoother but can wick more slowly in a low-power device like this.

Performance and puff delivery

Refillable pod kits do not have a fixed puff count the way disposables claim to, because the number of puffs depends entirely on how much e-liquid you put in, how strong it is, how long you inhale for and how often you vape. As a rough benchmark, a 2ml pod of 20mg nicotine-salt liquid typically lasts a light user a full day or a little more. Someone who vapes frequently might empty a pod in around half a day. If you want a figure to compare against disposables, many vapers find that a full 2ml fill delivers somewhere in the region of 300 to 500 puffs at typical MTL draws, though real-world numbers vary widely.

The Infinix is tuned for restricted, mouth-to-lung puffing. That means the airflow is relatively tight, the vapour production is modest and the hit is closer to the feel of a cigarette than to the large clouds produced by sub-ohm hardware. If you have used low-power pod systems before, the performance will feel familiar. If you are coming from a high-wattage box mod and expect dense, warm vapour, you will find the Infinix gentler than you are used to.

The draw-activated firing is quick, and with a properly primed pod you should get a smooth, consistent response from the first puff. Because the output is not adjustable, consistency matters more than raw power. The coil reaches working temperature within a fraction of a second, so there is little of the lag you sometimes see in older pod designs. Leave a few seconds between puffs and the wicking has time to keep up, which helps avoid the dry, harsh taste that comes from firing a coil that has not been resupplied with liquid.

Where performance can drop is when you chain vape, meaning you take many puffs in quick succession. A small battery and a low-power coil can both struggle to maintain output if you hammer the device. For best results, take measured puffs of two to four seconds with a short pause between them. This is also kinder to the coil and extends pod life.

It is also worth being honest about what the Infinix is not. It is not a cloud-chasing device, and it is not designed for direct-to-lung inhaling. If you want large, warm vapour, a sub-ohm kit is a better match. The Infinix is aimed at people who want a discreet, satisfying throat hit and an easy switch from smoking or from disposables.

Flavour profile and what to expect from different e-liquids

One of the main reasons people choose a refillable pod kit over a disposable is that the flavour is entirely in your hands. The Infinix itself has no flavour. It is a neutral delivery system, and the taste you get depends on the e-liquid you fill the pod with. That said, the hardware does shape how a liquid comes across, so it helps to know what to expect.

Small-coil MTL devices like this tend to deliver flavour that is concentrated and focused rather than diffuse. Because the vapour is cooler and the airflow is tight, subtle notes in a liquid are easy to pick out. Fruit blends, menthol and mint, and clean dessert profiles generally work well. Very heavy, sweet liquids can sometimes gum up small coils faster, so if you enjoy rich custards or sugary candy flavours, expect to replace pods a little more often.

• Fruit and ice: works very well. Juicy flavours and a cooling agent come through clearly at this power level.
• Menthol and mint: a strong match for the tight draw, delivering a crisp finish without the harshness that sometimes comes from higher-wattage devices.
• Tobacco: suitable for ex-smokers who want a familiar profile. Lighter tobacco blends tend to taste cleaner than very sweet ones.
• Desserts and creams: enjoyable, but thick, sugar-heavy liquids may shorten pod life.
• Drinks and sours: generally pleasant, with bright top notes that suit a cooler vapour.

Nicotine salt liquids are the natural pairing for this class of device. Salts deliver a smoother throat hit at higher strengths than traditional freebase nicotine, which makes a 10mg or 20mg liquid more comfortable to inhale. If you use freebase liquid, stick to lower strengths, because the harshness of freebase at higher strengths is noticeable in a tight-draw device.

Choose a liquid with a balanced PG/VG ratio for the best results. A 50/50 blend flows through the wick freely and keeps flavour crisp, while very high VG liquids can be thick for small pod coils. The product family on this page offers several options, but because the kit is refillable, the colour or finish you pick does not lock you into a flavour. You can fill the pod with anything compatible, and swap to a different flavour whenever you like by emptying and rinsing or by replacing the pod.

When switching flavours, remember that coils hold on to residual taste. If you move from menthol to a fruit liquid, you may notice a lingering hint of the previous flavour. Fitting a fresh pod when you change profile is the simplest way to keep each flavour distinct.

Design and build quality

The Infinix follows a slim, rounded format that sits comfortably in the hand and pocket. The body is compact enough to hide inside a closed fist, and it is light enough that you will not feel it hanging in a jacket pocket or bag. That portability is the main design pitch, and for most users it works. If you spend a lot of the day moving around, commuting or working in places where you want to keep your kit discreet, a small body is a genuine advantage.

The outer shell is a hard finish that resists casual scuffs but, like any painted or coated surface, will pick up marks if it shares a pocket with keys or coins. A silicone sleeve or a small pouch is cheap insurance if you want to keep the finish looking tidy. The four options in this product family differ in their finish, so you can match the device to your taste without changing how it performs.

The pod clicks into the battery body with a magnetic or snug-fit connection, and it should seat firmly with an audible or tactile click. A secure fit matters, because a loose pod can cause intermittent firing or leaks. If the pod does not seat cleanly, remove it, check that the contacts are free of residue, and reinsert it.

The mouthpiece is shaped for comfortable lip contact. It is narrow, which suits the tight-draw design, and it sits flush with the body rather than protruding awkwardly. Because there is no button, the front of the device is uncluttered. A small LED indicator tells you when the battery is low or charging.

As for durability, the Infinix is built to a price, which is reasonable to say about any compact pod kit at this level. It is not a rugged device designed to survive being dropped onto concrete repeatedly, but with normal care it should last well. The areas that most often wear are the pod contacts and the charging port, so keep both clean and dry. Avoid carrying the kit loose in a pocket with the pod full of liquid and the fill port unsealed, since pressure changes and warmth can encourage seepage.

On the whole, the design suits the intended use. It is small, light and plain. If you want extras such as a screen, adjustable airflow or a replaceable battery, you are looking at a higher tier of device. For a straightforward daily pod kit, the build is appropriate.

Battery life and charging

The built-in battery of roughly 250mAh is the most limiting number on the specification sheet, and it is worth setting expectations accurately. A battery of that size will not carry a heavy vaper from morning to night. Light users who take occasional puffs through the day may get a full day from a charge. Moderate users commonly find they need a top-up by late afternoon or evening. Heavy users will probably want to charge more than once a day or keep a charging cable within reach.

The reason battery life is shorter than on larger devices is simple physics. Capacity is measured in milliamp-hours, and a 250mAh cell holds only a fraction of the energy stored in the 700mAh to 1000mAh cells found in larger pod kits. In return, you get a smaller and lighter body. Which of these trade-offs matters more depends on your habits.

Charging is done through the USB port on the body using the supplied cable. Charging times for a cell this size are short, generally under an hour from low, so a quick top-up while you are at a desk or in the car can restore a useful amount of charge. The LED indicator will signal charging and, on many units, will change behaviour when the battery is full. Do not leave the device charging unattended overnight as a matter of routine, and avoid covering it with fabric while it charges.

• Use a standard 5V USB source such as a phone charger of modest output or a computer port. Avoid unregulated, cheap, unbranded chargers.
• Charge on a hard, non-flammable surface, away from direct heat.
• Unplug when the indicator shows a full charge.
• Do not use the device while it is plugged in unless the instructions say that is safe.
• If the device becomes unusually hot, swells or smells of burning, stop using it and contact the retailer.

Because the battery is built in, it cannot be swapped out. Over many months of use, the cell will gradually lose capacity, which is normal for any lithium-ion battery. When it no longer lasts long enough to be practical, the device has reached the end of its useful life.

When that happens, dispose of it responsibly. In the UK, vapes and their batteries fall under waste electrical regulations, and retailers that sell them are required to offer take-back. You can also use household waste recycling centres and designated drop-off points. Never put a vape in household rubbish or ordinary recycling, because the lithium battery can cause fires in collection vehicles and sorting plants.

Coil and mesh technology explained

The coil is the heating element that turns e-liquid into vapour, and it largely determines the flavour, throat hit and lifespan of a pod. On the Infinix, the coil comes built into the pod, so you do not wind, wick or install anything yourself. When the coil wears out, you replace the whole pod. That makes the system very simple to maintain, though it also means the running cost of the coil is bundled into the cost of each pod.

There are two broad coil families you will encounter in pod systems. Traditional round-wire coils use a coiled wire wrapped around a cotton wick. Mesh coils use a flat sheet of woven or perforated metal that wraps around the wick, giving a larger heating surface area. Mesh generally warms up quickly, heats the liquid more evenly and tends to produce more flavour for a given power level. Round-wire coils are usually cheaper to manufacture and can give a slightly sharper throat hit.

Pods of this type use low-to-mid resistance coils, with values commonly between roughly 0.8 and 1.2 ohm. Resistance is a measure of how strongly the coil resists the flow of current. In simple terms, a higher-resistance coil draws less power from the battery and suits a tighter, cooler MTL puff, while a lower-resistance coil draws more power and produces warmer, denser vapour. Because the Infinix has a fixed output, the resistance of the pod you fit is the main thing that sets the character of the vape.

Wicking is the process by which liquid travels from the pod reservoir into the cotton around the coil. Good wicking keeps the coil supplied so it never fires dry. A few habits protect it:

• Prime every new pod. After filling, let the pod stand for five to ten minutes so the cotton becomes fully saturated before the first puff.
• Take gentle puffs. Long, forceful draws can pull liquid faster than the wick can replenish it.
• Avoid running the pod empty. Firing a coil with little or no liquid scorches the cotton and ruins the flavour permanently.
• Match the liquid to the coil. Thin to medium liquids, such as 50/50 or 60/40 PG/VG blends, wick best in small pod coils.

A typical pod coil lasts somewhere between one and three weeks for an average user, but lifespan varies with how often you vape and what you vape. Sweet liquids leave sugar deposits on the coil, which gradually dull flavour. When the vapour starts tasting burnt, flat or muted despite a fresh fill, the coil has done its job and it is time to fit a new pod.

Choosing the right nicotine strength

Picking the right nicotine strength matters more than most beginners expect. Too low and you will not feel satisfied, and you may end up vaping more often than you want. Too high and you may feel lightheaded, nauseous or throat-sore. Because the Infinix uses a small, low-power, mouth-to-lung design, it works best with nicotine salt e-liquids in the lower to middle strength range.

In the UK, the legal maximum nicotine strength for vaping liquid is 20mg/ml, which is the same 2% ceiling applied to all nicotine vapes. Anything labelled higher than that is not legitimate for sale in this market. Strengths are normally offered as 0mg, 3mg, 6mg, 10mg, 12mg and 20mg, with salts commonly sold at 10mg and 20mg, and freebase liquids at 3mg, 6mg and 12mg.

• Heavy smokers (20 or more cigarettes a day): many start with a 20mg nicotine salt liquid. If it feels too strong, step down to 10mg or 12mg. Note that a small battery and low power output mean you are unlikely to overdose on nicotine through vapour production alone, but you may feel the effect more at 20mg than you expect.
• Moderate smokers (10 to 20 a day): a 10mg to 12mg salt is usually a comfortable starting point.
• Light or social smokers: 5mg to 6mg, or a 10mg salt used sparingly, often suffices.
• Former disposable users: most disposables in the UK are set at 20mg, so a 20mg salt will feel familiar. If you find yourself vaping less often than you used to, 10mg may suit you better and will last longer.
• Non-smokers: vaping is not recommended for people who do not already use nicotine. If you are determined to try a pod kit, 0mg liquid carries no nicotine.

Salts versus freebase is the other consideration. Freebase nicotine produces a harsher throat hit as strength increases, which is why it is rarely sold above 12mg. Nicotine salts are formulated to be absorbed more quickly and feel smoother, which allows higher strengths to be comfortable. In a tight-draw device like the Infinix, salts are generally the better fit for anyone who wants to replace cigarettes.

If you are unsure, start one step lower than you think you need and move up if you find yourself reaching for the device constantly or still craving cigarettes. It is easier to increase strength than to recover from taking too much. And if your aim is to cut down over time, the refillable format makes it simple to drop to a lower-strength bottle gradually without changing hardware.

Who the Infinix suits, and who should look elsewhere

No pod kit suits everyone, and being clear about fit saves you money. The Infinix is a deliberately simple, small device, so it has a clear target audience as well as some groups who will be better served by something else.

The kit is a good match for:

• Smokers switching to vaping. The mouth-to-lung draw and nicotine salt compatibility mimic the feel of a cigarette closely, which many people find helpful when they are trying to move away from tobacco.
• Disposable users moving to refillable. If you have been buying disposables repeatedly and want a more economical, more sustainable option, a pod kit gives you the same simplicity with refills instead of throwaways.
• People who value discretion. The small body is easy to carry and easy to conceal, which suits commuting, travel and busy days.
• Beginners who dislike fiddling. With no settings, no buttons and no coil building, there is very little that can go wrong.
• Light to moderate vapers. If you take a few puffs here and there during the day, the battery and pod size match your usage well.

You may want to look at other options if you:

• Vape heavily throughout the day. A 250mAh battery will keep asking for a charge, and a 2ml pod will need refilling often.
• Want large clouds. The Infinix is a restricted-draw device and will not produce the dense vapour associated with sub-ohm hardware.
• Want adjustable settings. There is no wattage or airflow control, so if you like to tune your vape, you will find it limiting.
• Prefer a replaceable battery. The cell is built in, so when it ages, the device is finished.
• Do not currently smoke or vape. Nicotine is addictive, and vaping is intended for adults who want an alternative to smoking.

It is also worth thinking about your environment. If you often charge at a desk or in the car, a smaller battery is less of a burden. If you spend long days away from a power source, you may prefer a larger device or carry a spare cable and power bank.

If you fall somewhere in the middle, the best way to decide is to think about how many puffs you take in a typical day and how often you can reach a charger. If the honest answer is a lot and rarely, a bigger battery will serve you better. If the answer is a little and often, the Infinix will do the job without fuss.

How to use the SMOK Infinix Pod Kit

Using the Infinix is straightforward, but a few careful steps at the start will save you leaks, dry hits and wasted liquid. Follow this routine whenever you fit a new pod or refill an existing one.

• Charge first. Plug the device in and give it a full charge before first use. A low battery can cause weak or inconsistent firing.
• Remove the pod. Pull the pod gently out of the battery body and set the body aside.
• Open the fill port. Lift or pull back the silicone plug on the pod. Keep the pod upright so liquid does not run where it should not.
• Fill slowly. Tilt the bottle nozzle against the side of the fill port and squeeze gently. Stop just below the maximum line. Do not overfill, and avoid dripping liquid into the central air tube, which causes gurgling and leaks.
• Close the port. Press the plug back in firmly and wipe away any spilled liquid from the outside of the pod.
• Let it prime. Stand the pod upright for five to ten minutes so the cotton wick can soak up liquid evenly.
• Reinstall and vape. Click the pod into the battery body and take gentle puffs. Start with a couple of short draws to bring the coil up to speed.

When inhaling, use a slow mouth-to-lung technique. Draw for two to four seconds into your mouth, pause briefly, then inhale into your lungs. Smooth and unhurried puffs preserve both flavour and coil life. If the vapour tastes hot or harsh, slow down and leave longer gaps between puffs.

Day-to-day care is minimal. Store the device upright when you can, keep the contacts clean, and wipe condensation off the mouthpiece with a dry tissue. Do not wash the battery body with water. If liquid gets into the connection area, remove the pod and let the device air-dry before using it again.

Always check the liquid level before leaving home. Never leave a pod empty and keep firing it, because a dry hit damages the coil. Refill when the level drops to a quarter, and replace the pod as soon as the flavour starts to taste burnt or flat.

Finally, keep e-liquid and the device out of reach of children and pets. Nicotine is a poison if swallowed, and e-liquid bottles should be stored upright and closed. Use only liquid that is labelled for use in e-cigarettes and complies with UK labelling requirements.

Troubleshooting common problems

Most problems with small pod kits have simple causes. Before assuming the device is faulty, run through the checks below. Many issues come from the pod rather than the battery, so swapping to a fresh pod is often the quickest test.

• The device does not fire. Check that the battery is charged and the pod is seated firmly. Remove the pod, wipe the metal contacts with a dry cotton bud, and reinsert it. If the LED flashes when you draw but the device still does not produce vapour, the coil may be dry or the pod may be empty.
• Weak vapour or muted flavour. This usually means the coil is tiring or the wick is not saturated. Prime a fresh fill for longer, or fit a new pod. Very thick liquid in a small coil can also cause this, so try a thinner PG/VG ratio.
• Burnt taste. The coil has been fired without enough liquid, or it is at the end of its life. Replace the pod and avoid chain vaping.
• Gurgling noise. Liquid has found its way into the airflow channel, often through overfilling. Remove the pod and blow gently through the mouthpiece with the airflow end held to a tissue, then wipe it dry.
• Leaking. Check the fill plug is seated correctly and the pod is not overfilled. Temperature and pressure changes, such as flying or leaving the device in a hot car, can encourage leaks, so store the kit somewhere stable.
• The LED blinks and the device will not respond. This is typically the low-battery indicator or a short-circuit protection signal. Charge the device and clean the pod contacts. If the problem persists, try a different pod.
• The device will not charge. Try a different cable and power source, and check the charging port for lint or dust. Use a wooden toothpick to clear debris gently.
• Sore throat or coughing. The nicotine strength may be too high for the way you are inhaling. Try a lower strength or slow your draw.

If you suspect a fault with the hardware itself, stop using it and contact the retailer with your order number and a short description. Do not attempt to open the casing, because the lithium battery inside can be dangerous if damaged.

Remember that pods and coils are consumable parts and wear with use. A pod that stops working after several weeks of regular vaping is usually worn rather than defective. If a new pod fails immediately or the device shows signs of damage such as a swollen body, unusual heat or a burning smell, treat it as a safety concern and stop using it.

Value for money and how it compares with rival pod kits

The Infinix is positioned as an affordable entry-level pod kit, so the question of value comes down to what you get for the money and what it will cost to run. The purchase price of the kit itself is modest. The ongoing costs are pods, which wear out every one to three weeks, and e-liquid. Because you choose the liquid, you can pick the price point that suits your budget, from inexpensive 10ml bottles to premium salts.

Compared with buying disposables, a refillable pod kit usually works out cheaper over a month or two. A frequent disposable user may spend a significant amount each week on throwaway devices, whereas a pod kit with a few bottles and the occasional replacement pod comes in noticeably lower. It also produces less electronic waste, since you are refilling rather than discarding the whole device after a few hundred puffs.

It helps to compare the Infinix fairly with rival systems at similar prices:

• Compared with larger Smok pod kits such as the Novo range: the Novo kits generally offer bigger batteries and slightly more output, which suits heavier use, while the Infinix is smaller and lighter. If battery life is your priority, a Novo is worth a look. If pocket size matters more, the Infinix has the edge.
• Compared with the Vaporesso XROS series: XROS devices typically carry larger batteries and offer adjustable airflow or power on some models, which gives more flexibility and longer endurance. The Infinix is simpler and smaller but needs charging more often.
• Compared with the Uwell Caliburn range: Caliburn kits are well regarded for flavour and a tidy draw, with larger batteries in most versions. They cost somewhat more in many cases. The Infinix competes on size and price rather than endurance.
• Compared with the OXVA Xlim range: Xlim kits offer adjustable output and sturdier build on several models, aimed at users who want more control. The Infinix is a plain, fixed-output alternative.

None of these comparisons make the Infinix a poor choice. They simply show where it sits. It trades battery capacity and adjustability for size, simplicity and low cost. If those priorities match yours, it offers fair value. If you vape heavily or want to tinker, you may find a larger competitor gives you more for a slightly higher outlay.

To keep costs down, buy e-liquid in larger bottles when you are settled on a flavour, avoid wasting liquid through overfilling, and take care of the coil so pods last longer. When the device finally reaches the end of its life, recycle it through a retailer take-back scheme or a local drop-off point rather than throwing it away.
