Aspire Cleito Pro Tank overview

The Aspire Cleito Pro Tank is a 24mm sub-ohm tank built around Aspire's Cleito coil system, and it is listed here at £4.99. It is a refined take on the original Cleito idea: a short, wide glass tank, a top-fill port so you can refill without taking anything apart, an adjustable airflow ring at the base, and a choice of two coil resistances that cover everything from a tight, cool draw to a warm, dense one.

Aspire has been making tanks since the early years of the modern vaping market, and the Cleito name sits in the middle of that catalogue. The Pro version keeps the familiar Cleito footprint but tidies up the airflow layout and pairs it with a coil lineup that suits current mods. The body is stainless steel and glass, the thread is a standard 510, and the diameter sits comfortably on most 22mm and 24mm mods without a visible lip. If you already own a Cleito or a Cleito Exo, the coils are interchangeable, which matters because coils are what you will be buying most often.

This page walks through what the tank is actually like to use. We cover the specifications, how it performs, which e-liquid styles suit it, the design, the coil technology, the power it needs, nicotine strength choices, who should buy it and who should skip it, how to fill and prime it, how to fix the usual problems, and how it compares with the rivals you are likely to be weighing up. We have tried to be straight about the limits as well as the strengths, because a tank at this price still has to earn its place on your mod, and it will not suit everyone.

One note on the figures before we start. Aspire has sold this tank in different markets with different glass sections, and retailer listings do not always agree on exact wattage ranges or heights. Where we give numbers below, treat the markings on the coil and the pack in your hand as the final word, and use our figures as a guide to what to expect rather than a promise.

Specifications at a glance

A quick reference list is useful before the detail. These are the figures we can reasonably stand behind for the Cleito Pro, with the caveats noted where listings differ.

• Thread: standard 510 connection, so it fits the great majority of regulated and unregulated mods.
• Diameter: 24mm at the widest point.
• Height: roughly 37mm for the tank body, rising towards 46mm once the drip tip is fitted. Listings quote both figures depending on what they measure.
• E-liquid capacity: 2ml in the version sold for UK nicotine e-liquid. Overseas listings show 3ml for the standard glass and 4.2ml for a bubble glass, which relate to other markets.
• Coils: a 0.5Ω Pro coil and a 0.15Ω mesh coil. Standard Cleito coils and Cleito Exo coils are also reported to fit.
• Power range: quoted at around 60W to 80W for the 0.5Ω Pro coil and a similar band for the 0.15Ω mesh coil. Quoted ranges differ slightly between sellers, so follow the wattage printed on the coil you install.
• Filling: top-fill through a port under the top cap.
• Airflow: adjustable ring at the base of the tank.
• Materials: stainless steel top and base with a glass tube.
• Battery: none. The tank is a passive component that sits on a mod, so battery capacity is a mod question rather than a tank question.
• Compatible e-liquid: 0mg to 20mg/ml nicotine, which covers the whole UK legal range for nicotine e-liquid.

The Cleito Pro should not be confused with the Cleito 120 Pro. The 120 Pro has a 25mm base, uses a different coil family and is aimed at higher wattage. Coils are not interchangeable between the two, so check the name on the box before you order replacements.

Because the tank is sold as an accessory, you will need a mod capable of delivering enough power, a safe battery and a charger. The sections on power and nicotine strength below explain what to match and why.

Performance and vapour production

The two coil options change the character of the Cleito Pro more than any other setting. The 0.5Ω Pro coil is the gentler choice. At the lower end of its range it gives a cool, moderate draw with a clear, rounded vapour that suits a mouth-to-lung style, where you take the vapour into your mouth first and inhale afterwards. Pushed towards the top of its rated power it becomes warmer and denser, and it begins to approach restricted direct-to-lung territory.

The 0.15Ω mesh coil is the performance option. Resistance this low draws far more current from the battery and produces a much larger volume of vapour, so it is intended for direct-to-lung inhalation with the airflow ring opened up. Expect a rapid ramp-up, a warm to hot draw at the upper end of the power range and a noticeably larger puff than the 0.5Ω coil can deliver. It also uses e-liquid faster, which is relevant on a tank with a 2ml capacity.

Airflow is controlled by the ring at the base. Closing it down tightens the draw and concentrates flavour, and opening it fully cools the vapour and increases volume. Most people settle on a position about halfway for the 0.5Ω coil and fully open for the 0.15Ω mesh. The slots are shaped so that air is directed toward the coil rather than straight past it, which helps to limit whistling and gives a smooth rather than airy draw.

Compared with the older Cleito, the Pro is better behaved at the edges. Spit-back, the small hot droplets that sometimes reach your lips, is uncommon when the coil is primed and used within its wattage range. Gurgling is also modest. The usual caveat applies: thin, high-VG e-liquids behave differently from thick ones, and a coil that is run too hot for the liquid will always misbehave.

Do not expect the vapour output of a large 5ml or 6ml tank with twin or triple mesh coils. This is a compact tank with one coil in a small chamber, and it delivers capable, consistent performance for its size rather than record-breaking clouds.

Flavour delivery and e-liquid pairing

A tank has no flavours of its own, so this section is about what the Cleito Pro does to the flavour of whatever you put in it. The short version is that the compact chamber and the 0.5Ω coil give a clear, focused flavour that carries well, while the 0.15Ω mesh coil produces a fuller, rounder, slightly warmer profile with more vapour to carry it.

Fruit flavours are the natural fit. Here are eight styles that suit the tank well, with the reasons why:

• Strawberry ice: the sweetness comes through cleanly on the 0.5Ω coil and the menthol stays crisp rather than harsh.
• Blue raspberry: a bold, sweet profile that benefits from the mesh coil's extra vapour density.
• Mango: tropical fruits can taste flat on weaker coils, but the Pro coils keep the juiciness intact.
• Apple and pear: light, sharp fruits show up well at lower wattage with the airflow part closed.
• Menthol and mint: a cool vapour from the open airflow gives a refreshing finish and avoids any burnt note.
• Tobacco: mellow, nutty tobacco liquids work on the 0.5Ω coil, where the lower heat keeps them smooth.
• Vanilla custard: thick desserts need a warmer coil, which the mesh option provides, though they gum up coils faster.
• Cola: the fizz and spice come across clearly without turning bitter at moderate power.

Heavily sweetened liquids are the exception to the rule. Dessert flavours with a lot of sweetener leave residue on coils, and a small coil chamber means that residue builds up faster. If you like dessert liquids, expect to change the coil a little sooner, and give it a good prime every time.

Switching flavours is straightforward, but it is worth being realistic. Cotton holds a flavour memory. If you are moving between very different profiles, such as mint and a rich custard, rinse the tank and fit a fresh coil to avoid ghosting, where the previous liquid taints the next one. If you vape a single flavour for a long time, the coil will often last longer than if you change constantly.

The tank handles both 50/50 and 70/30 VG mixes. Thicker, higher-VG liquids suit the 0.15Ω mesh coil, while a 50/50 or 60/40 blend is the sensible choice for the 0.5Ω coil, where thinner liquid wicks more easily at moderate power.

Design and build quality

The Cleito Pro has a short, squat silhouette that sits tidily on small and mid-sized mods. At 24mm in diameter it matches the width of many popular pod-mods and box mods, so it rarely overhangs. The stainless steel top and base carry a brushed or polished finish depending on the colour, and the glass tube is thick enough to feel solid without making the tank heavy. Finishes have included gold and silver tones, and what you receive depends on stock, so treat the product photo as indicative.

The top-fill system is one of the more practical features. You open the top cap to expose a fill port and pour e-liquid in without removing the tube or the coil. This is a better arrangement than a bottom-fill tank, where you need to unscrew the base and risk spilling, and it makes refilling on the move much easier. The port is a reasonable size, but the nozzle of a long, thin bottle is easier to use than a wide one. Take care to aim away from the central airflow tube so you do not flood the coil.

The airflow ring turns smoothly with a light resistance, enough to stay where you set it but not so stiff that you need two hands. The thread between the coil and the base is finely cut, and the O-rings supplied seat well when the tank is assembled properly. As with any tank, it is worth checking each ring is in place and undamaged before filling. A pinched or missing ring is the most common cause of leaks.

The supplied drip tip is a wide-bore design that suits both mouth-to-lung and direct-to-lung use, and it is easy to swap for a standard drip tip of the same fitting if you prefer a different shape. The overall finish is what you would expect from an established brand: not luxury, but cleanly machined and consistent.

One limitation worth mentioning is size. The 2ml capacity means frequent refills for heavy vapers, and the glass is a fixed size in the UK version. If you want a long-lasting tank, look at larger models. If you value a compact setup that is easy to carry, the Cleito Pro is a good match.

Coil technology: the 0.5Ω Pro and 0.15Ω mesh options

The coil is where a tank makes or breaks the vaping experience, and the Cleito Pro offers two quite different options. Understanding how they differ will help you choose correctly and avoid wasting coils.

The 0.5Ω Pro coil. A resistance of 0.5Ω puts the coil at the lower end of what most people consider sub-ohm territory, close to the boundary with standard resistance coils. It draws moderate current, produces a comfortable amount of vapour and puts less strain on the battery. It is usually the better pick for new sub-ohm users and for anyone who prefers a cooler draw. Quoted power sits at around 60W to 80W, though many people find the sweet spot nearer the lower half of that band.

The 0.15Ω mesh coil. Mesh coils replace a round wire wound around a cotton wick with a flat sheet of mesh that touches a wider area of wick. The larger surface area heats the e-liquid more evenly and more quickly, which usually means better flavour for the same power and a shorter ramp-up. At 0.15Ω the coil is very low resistance and draws a lot of current, so it demands a mod and battery that can supply it safely. It is rated around a similar wattage band to the 0.5Ω coil in many listings, though the variation between sellers is greater here, so follow the figure on the coil itself.

Battery safety matters more at low resistance. Any mod you pair with the 0.15Ω coil should be able to supply the current without exceeding the battery's continuous discharge rating. A mod with built-in protection and a proper high-drain battery is the sensible choice. Ask us or check the mod's manual if you are unsure.

Because standard Cleito coils and Cleito Exo coils are reported to fit, you have a wide selection of replacement heads. That is a real advantage, because it means you are rarely forced to buy one particular type. If you mix and match, always read the resistance and power range on the coil before you use it.

Coil life depends on liquid, power and habit. Light, clear fruit liquids at moderate power can give a coil two weeks or more of regular use. Sweet, dark dessert liquids at high power may shorten that to a week. A burnt taste, a gurgling sound or a drop in vapour volume are the signs that it is time for a fresh coil.

Battery, mod pairing and charging

The Cleito Pro has no battery of its own, so there is nothing on the tank to charge. All the power comes from the mod it sits on, and the choice of mod determines how the tank behaves. This section covers what to look for.

For the 0.5Ω Pro coil, a single 18650 battery mod delivering up to 80W is a reasonable match, and many compact box mods fit the bill. For the 0.15Ω mesh coil, you will want a mod that is happy to fire at sub-0.2Ω and can deliver the current safely. A dual 18650 mod gives more headroom and longer runtime, though it is heavier and bulkier.

Battery capacity is the factor that decides how long a charge lasts. A typical 18650 cell sits somewhere between 2,500mAh and 3,500mAh, and a high-drain cell rated for the current you are drawing is more important than the headline mAh figure. At 60W on the 0.5Ω coil, a single 3,000mAh cell will usually last a good part of a day of moderate use. At 70W or more on the 0.15Ω coil, expect a single cell to drain noticeably faster and be prepared to carry a spare.

• Use only batteries rated for the continuous current your coil demands.
• Keep spare cells in a plastic case, never loose in a pocket with coins or keys.
• Charge in an external charger or a mod with proper charging protection, and do not leave batteries charging unattended overnight.
• Replace cells that show damage to the wrap or that have been dropped.

If your mod charges through a USB port, a standard phone charger is generally fine, but use a reputable one and avoid charging while vaping. If you use external cells, a proper two-bay or four-bay charger is a worthwhile purchase.

When batteries come to the end of their life, do not put them in your normal bin. Lithium cells can start fires in bin lorries and recycling plants. Take spent batteries to a battery recycling point, which you will find at most supermarkets and household waste recycling centres. The same advice applies to any mod you replace, as electronic waste should be dropped off at a council recycling site or returned to a retailer that offers take-back. The tank itself is stainless steel and glass, so it is also best recycled at a drop-off point rather than thrown in general waste.

Nicotine strength guidance

The tank does not contain nicotine, but the strength of the e-liquid you put in it matters a great deal. UK rules cap nicotine e-liquid at 20mg/ml, and the same ceiling applies to the disposable vapes sold in the UK. For a refillable tank like the Cleito Pro, the strengths you will see sold are typically 0mg, 3mg, 6mg, 12mg and 18mg, with nicotine salt liquids at 10mg and 20mg. Bottles are limited to 10ml for nicotine e-liquid, which is why many people buy a few at a time.

The right strength depends on how much vapour you produce, because the nicotine you take in is roughly the strength of the liquid multiplied by the amount you inhale. A sub-ohm tank produces large volumes of vapour, so the same liquid delivers more nicotine per puff than a small pod device would. That is why freebase liquids for sub-ohm tanks tend to be low strength.

• 0.15Ω mesh coil, direct-to-lung: 0mg to 3mg freebase is typical. Anything higher can be harsh and deliver more nicotine than you need.
• 0.5Ω Pro coil, mouth-to-lung: 3mg to 6mg freebase suits most former smokers. Heavier smokers may prefer 12mg.
• Nicotine salts: 10mg is a sensible starting point at moderate power. 20mg is the legal limit and is strong. Salts are smoother, but the nicotine arrives faster, so use them with care in a tank that produces significant vapour.

If you are moving from smoking, a good approach is to start at the lower end of the range for your coil and adjust. If you feel lightheaded, nauseous or jittery, the strength is too high. If you are reaching for a cigarette or vaping constantly, it may be too low. Give any change a few days before judging it.

If you are an ex-smoker aiming to cut down, many people reduce strength gradually over several months. Zero-nicotine liquid is available in the same flavours, so you can keep the habit of vaping while reducing nicotine. Anyone who has never smoked or vaped should not start, as nicotine is addictive. This tank is for adult smokers looking for an alternative, and it must only be bought by people aged 18 or over.

Who the Cleito Pro suits, and who should skip it

No tank suits everyone, and being clear about that saves you money. Here is a direct assessment of who gets the most from the Cleito Pro.

It suits:

• Vapers who already own a mod and want a compact, tidy tank that does not overhang a 24mm setup.
• People moving from a pod device to their first sub-ohm tank, who can start on the 0.5Ω coil and move to mesh later.
• Existing Cleito or Cleito Exo owners who want a refreshed tank while using coils they already know.
• Anyone who wants top-fill convenience and an adjustable draw without paying for a large premium tank.
• Flavour-focused vapers who prefer a compact chamber that keeps the taste concentrated.

You should look elsewhere if:

• You vape heavily and dislike refilling. The 2ml capacity means a top-up several times a day at higher power.
• You want large clouds above all else. A bigger tank with dual mesh coils will do that better.
• You do not already own a suitable mod. The tank is not a starter kit, and you will need a mod, a safe battery and a charger as well.
• You prefer the simplicity of a pod system or a disposable. A tank takes some learning, with priming, filling, coil changes and cleaning to think about.
• You use very thick, sweet dessert liquids all day. These will shorten coil life considerably in a small chamber.

The tank is also a reasonable choice for someone who wants to experiment. At this price, trying a mesh coil or a different airflow setting is a low-risk step, and you can keep the tank as a backup or a dedicated flavour tank for a favourite liquid.

Finally, remember that vaping is for adults. The tank is not suitable for anyone under 18, for non-smokers, or for people who are pregnant or have a heart condition without first speaking to a healthcare professional. If you are trying to quit smoking, local stop-smoking services in the UK can offer support alongside vaping.

How to fill, prime and use the tank

Getting the setup right the first time prevents most problems. Follow these steps for a new tank or a fresh coil.

• Rinse and dry: Take the tank apart and rinse the glass and metal parts in warm water, then dry them thoroughly. This removes any residue from manufacturing.
• Check the O-rings: Make sure every seal is in place and undamaged. This is the single most useful check you can make.
• Fit the coil: Screw the coil firmly into the base. Hand-tight is enough. Do not overtighten.
• Prime the coil: Drip a few drops of e-liquid directly onto the cotton through the coil's side holes until it is visibly dark and saturated. Skipping this step is the usual reason for a burnt first hit.
• Assemble and fill: Put the glass back, attach the base, then open the top cap and fill through the port. Fill to just below the top, and avoid dripping liquid into the central airflow tube.
• Wait: Let the tank sit for five to ten minutes, which lets the e-liquid soak through the cotton fully. Thicker liquids need the longer end of that range.
• Set the airflow: Start with the ring about halfway open.
• Set the power: Start at the bottom of the coil's range and increase in small steps until the flavour and warmth suit you.
• First puffs: Take a few short, gentle draws without firing for long, to let the liquid reach the wick.

On a variable wattage mod, you set the power with the mod's controls. On a regulated mod with a coil recognition feature, the mod may suggest a wattage automatically. Always stay inside the range printed on the coil.

Keep the tank upright when storing it, and do not leave it on a hot dashboard or in direct sunlight. Heat thins e-liquid and increases the risk of leaks. If you travel by air, empty the tank first or carry it upright in a sealed bag, as changes in pressure can push liquid out of the airflow slots.

For refilling, wait until the tank is a quarter full rather than letting it run dry. A coil that fires with a dry wick will burn in a matter of puffs, and that burnt cotton cannot be rescued.

Troubleshooting and care

Most tank problems come down to a handful of causes. Work through these before deciding that something is faulty.

• Burnt taste: Usually a dry or poorly primed coil, or a coil that has reached the end of its life. Re-prime, let it soak, and lower the power. If the taste persists, fit a new coil.
• Leaking from the airflow slots: Check the O-rings and make sure the base is tightened properly. Overfilling, hot storage and low-viscosity liquid can also contribute. Wipe the tank clean and refit the seals.
• Gurgling: Excess liquid in the airflow path. Tilt the tank, remove the drip tip and blow the liquid away from the chamber, and check that you did not overfill.
• Weak vapour: Either the coil is tired, the power is too low, or the wick is not getting enough liquid. Check the fill level, increase power slightly and replace the coil if the problem remains.
• Spit-back: Too much power for the liquid, or a coil that has not been primed. Lower the wattage a little.
• Mod shows an atomiser error: Unscrew the tank, clean the 510 contact and reseat it. Make sure the pin height is correct and the coil is firmly seated.
• Whistling airflow: Change the airflow ring position slightly. This usually resolves it.

To clean the tank, take it apart and soak the glass and metal parts in warm water with a drop of washing-up liquid, rinse thoroughly and let everything dry fully before you refill. Do this whenever you change the coil, or sooner if you switch flavours.

When a coil is spent, unscrew it and recycle it where possible. Coils, mods and batteries should not go in the general bin. Most UK local authorities have recycling drop-off points for small electrical items and batteries, and many shops that sell vape products will take back used items. The stainless steel and glass of the tank can be recycled at the same drop-off points when it reaches the end of its useful life.

If a fault appears in a brand-new tank, such as a cracked glass tube, a thread that will not seat or a missing seal, contact us promptly with a description and a photograph so that we can help.

Value for money and how it compares with rivals

At £4.99, the Cleito Pro is among the cheaper ways to put a sub-ohm tank on a mod. The tank itself is the smaller part of the cost over time, though. The ongoing spend is coils, and the Cleito range has the advantage of wide coil availability and the option to use Cleito and Cleito Exo coils. Because coils are the main running cost, a tank with easy access to inexpensive heads is more economical over a year than a cheaper tank with scarce or costly coils.

Here is how it stacks up against tanks you may be considering, with honest notes on where each one has the edge.

• Aspire Nautilus family: The Nautilus is a long-standing favourite for mouth-to-lung vaping, with a bottom vertical coil and a gentler draw. It is a better choice if you want a very tight, cigarette-like inhale. The Cleito Pro offers more airflow, a mesh option and a bigger vapour ceiling.
• Freemax mesh tanks: Freemax sells larger, mesh-focused tanks with greater capacity in markets that allow it. In the UK 2ml format they are comparable in capacity, and some give a slightly richer flavour. The Cleito Pro has the advantage of compact size and interchangeable Cleito coils.
• Uwell Crown series: The Crown tanks are bulkier and aimed at stronger output, with strong flavour. They are heavier and wider. If you want a compact setup, the Cleito Pro is easier to live with.
• SMOK TFV series: SMOK tanks often produce more vapour and offer a wider coil range, but they are larger and use coils that can cost more. The Cleito Pro is a simpler, lighter package.
• Pod systems and disposables: They are easier to use and need no mod, but the running cost per day tends to be higher and the flavour is less adjustable. A tank gives you more control over strength, flavour and power.

The Cleito Pro does not win on every measure. Capacity is small, and it will not match the output of a modern large mesh tank. It does, however, offer a sensible balance of size, flavour, flexibility and price, and it works well as a first sub-ohm tank or as a spare for a favourite liquid.

To keep costs down, buy coils in packs rather than singly, prime them properly, avoid running them at the top of the power range and keep liquid sweetness in check. Those four habits extend coil life more than anything else.
