Nexus 100ml Shortfill overview

Nexus 100ml Shortfill is a nicotine-free e-liquid sold in a large bottle that is deliberately not filled to the brim. The empty space at the top is there for a reason. It lets you add one or two 10ml nicotine shots and finish with a full bottle at a strength you have chosen yourself, or leave the bottle as it is and vape it at 0mg. It is built for people who already use a refillable device, whether that is a sub-ohm tank, a mid-power pod mod or a refillable pod kit, and who would rather buy liquid by the 100ml than by the 10ml.

On this page we explain what is in the bottle, how the mixing works, what kind of hardware suits a liquid like this, how long a bottle tends to last, how it compares with the alternatives and what to do if something goes wrong. We have stuck to details that can be reasoned from the format and from the way UK shortfills are normally made. Where a detail changes from one flavour to the next, such as the exact VG and PG split or the exact fill volume, the variant listing and the label on your bottle are the final word, and we say so rather than guess.

• Product: Nexus 100ml Shortfill, sold by the bottle, with the flavour chosen on the product page
• Type: nicotine-free e-liquid for refillable devices; nicotine is only added if you choose to add a shot
• Typical base: high-VG, which is the normal choice for shortfills made for sub-ohm and mid-power kits
• Suits: sub-ohm tanks and refillable pod kits running coils from roughly 0.3 to 0.8 ohm
• Age restriction: 18 and over only
• Does not suit: disposable vapes, sealed pre-filled pods, or any device that cannot be refilled

Because the bottle contains no nicotine until you add it, the liquid itself is the simple half of the equation. The decisions that matter are the strength you mix to, the coil you pair it with and the power you run it at. Those are the topics for the sections below.

How a 100ml shortfill works and what the UK rules mean for you

In the UK, e-liquid that contains nicotine is limited to a maximum strength of 20mg/ml and to bottles no larger than 10ml, and refillable tanks are capped at 2ml. Those limits are the reason nicotine liquids come in small bottles. A shortfill gets around the bottle size limit in a straightforward and lawful way: the liquid inside is sold with no nicotine at all, so it can be supplied in a much bigger bottle. The bottle is left with headroom so that you can add a separate 10ml nicotine shot, which is a small bottle of concentrated nicotine in a PG and VG base, usually 18mg/ml, and shake the two together.

The 'short' in shortfill refers to the bottle being short of liquid by design, not short of quality. The final strength depends on how many shots you add and how much liquid is in the bottle when you finish. The sum is simple: strength in mg/ml equals the number of shots multiplied by 10 multiplied by 18, divided by the total millilitres in the bottle after the shots go in.

• 80ml of liquid in a 100ml bottle, one shot added: 90ml in total, about 2mg/ml
• 80ml of liquid in a 100ml bottle, two shots added: 100ml in total, about 3.6mg/ml
• 70ml of liquid in a 100ml bottle, three shots added: 100ml in total, about 5.4mg/ml
• 100ml of liquid in a 120ml bottle, two shots added: 120ml in total, exactly 3mg/ml
• Any bottle with no shot added: 0mg/ml

These examples assume standard 10ml shots at 18mg/ml. Shots at 20mg/ml exist and push the result slightly higher. The reason we list several scenarios is that the number '100ml' in a shortfill name can describe either the bottle size or the volume of liquid, and it differs between ranges. Read the fill volume and bottle capacity on the label or the variant listing before you buy your shots, and do the sum once so you know exactly what you are making.

Stay with standard freebase nicotine shots for mixing into a high-VG shortfill. Nicotine salt liquids are designed for low-power devices and are a separate product category, and a salt shot gives a different throat feel from a freebase one at the same milligram figure. If you are unsure which shot to buy, the product description on the shot will say whether it is intended for shortfill mixing.

Performance and vapour delivery

A bottle of liquid does not have a puff count printed on it the way a disposable does, because the number of puffs depends on your device, your power setting and how long you inhale for. We can still give a realistic range. A typical 2 to 3 second draw on a mid-power pod kit at around 20 to 25 watts uses roughly 0.015ml of liquid, which works out at around 60 to 70 puffs per millilitre. A longer draw on a sub-ohm tank at 40 to 50 watts uses noticeably more, closer to 25 to 35 puffs per millilitre. Across the likely range, an 80ml bottle is in the region of 2,000 to 5,500 puffs, and a 100ml fill goes proportionally further. Treat these as planning figures rather than guarantees.

What those figures mean in days depends on how much you vape:

• Light use, around 1 to 2ml a day: a bottle can last well over a month
• Moderate use, around 3 to 5ml a day: roughly two to four weeks
• Heavy sub-ohm use, around 8 to 10ml a day: about ten days to two weeks

Vapour production is mostly a result of the VG content and the coil. A high-VG liquid produces dense, soft vapour, which is why shortfills are the usual choice for sub-ohm vaping. The trade-off is thickness. High-VG liquid moves through the cotton more slowly than a thinner liquid, so the coil you choose has to be able to keep up. Mesh coils with large wicking surfaces handle this well. A very small coil with tiny wicking holes, run at high power, is where dry hits start.

Throat hit depends on strength and temperature. At 0mg there is almost no throat hit at all, only warmth and vapour. At 3mg the hit is gentle, and at 6mg it is firmer but still smooth in a sub-ohm device because the high airflow dilutes it. If you move from a stronger liquid in a mouth-to-lung device, expect the 3mg to 6mg range in a bigger tank to feel lighter than the number suggests. That is normal, and it is the reason we cover strength choice in detail further down.

Consistency across the bottle is another point worth noting. Because you are mixing nicotine into a liquid, shaking the bottle properly after adding shots matters. A bottle that has been given a quick wobble can have a stronger layer at the bottom and a weaker one at the top, so the first tank can taste different from the last. Give it a thorough shake and then a second shake after it has rested for a few minutes.

Flavour profile and choosing a variant

Nexus 100ml Shortfill comes in more than one flavour, and the flavour is selected from the options on this product page. Each variant has its own description, and that description is the best guide to what is in the bottle. Rather than attach tasting notes to flavours we cannot taste for you, we have set out how the main flavour families behave in a high-VG shortfill so you can match your choice to your habits.

• Fruit flavours: usually bright and sweet at the front. Berry and tropical profiles tend to hold their character well at mid power, and they often sit comfortably at 3mg
• Ice and menthol styles: add a cooling finish that also makes the throat feel smoother. They are popular for all-day vaping, but heavy menthol can dull some of the fruit flavour underneath
• Dessert and bakery styles: richer and thicker, with sweeteners that coat the coil faster. Expect to change coils a little sooner than you would with a fruit or ice liquid
• Drinks and soda styles: tend to be crisp and light, and they take well to being vaped at lower power
• Tobacco and custard styles: subtle, with flavour that develops more at slightly higher temperatures

High-VG liquid carries flavour differently from a balanced 50/50 liquid. The vapour is thicker and cooler for the same power, which means flavour can be a touch softer at low wattage. If a liquid tastes flat, raise the power a few watts rather than assuming it is the liquid, and make sure the coil has been primed properly.

Flavour also changes when you add nicotine. Freebase shots add a little throat hit and a very slight peppery note that can pull on delicate fruit and soda flavours. At 3mg the change is small. At 6mg you may notice the top notes sit a little differently. If you find the first tank off, leave the mixed bottle to rest for a day with the cap on and shake it again. Most people find the flavour settles and rounds out after that.

If you want to get the most from a new flavour, vape the first tank at a moderate power and judge it before experimenting. A new coil can taste slightly of cotton for the first few puffs, and judging a flavour on a fresh coil that has not been primed tends to be unfair to the liquid.

Bottle design and build quality

Shortfills are sold in soft, squeezable plastic bottles with a narrow, long nozzle, often called an unicorn or chubby-style bottle. The shape is practical rather than decorative. The squeezable body lets you control the flow into a tank, the thin tip fits into most tank fill ports including the small ones on pod kits, and the headroom at the top makes it easy to pour in a nicotine shot without spilling.

There are a few build details worth checking when your bottle arrives.

• Tamper-evident seal: the ring at the base of the cap should be intact when the bottle arrives. If it is already broken, contact us before you use it
• Cap and nozzle: the nozzle should be firmly seated and the cap should close with a clear click or firm resistance. Many nicotine-ready bottles use a child-resistant cap, and it is worth keeping that function working
• Label: a proper label shows the product name, flavour, volume, VG and PG ratio, ingredients, batch code and the safety information required for e-liquid in the UK
• Plastic: the bottle body should feel flexible but not thin or brittle. If it has been crushed in transit it can still be usable, but check that no liquid has seeped around the cap

Storage matters more than most people expect. Keep the bottle upright, in a cool, dark place, away from direct sunlight and radiators. Heat and light degrade e-liquid over time, darkening the colour and dulling the flavour. A bottle left on a sunny windowsill will not last as long as one kept in a drawer. Keep it out of reach of children and pets at all times, and remember that once you have added nicotine shots it is a nicotine product and needs to be treated that way.

For travel, wipe the nozzle clean, close the cap firmly and keep the bottle in a sealed bag. Changes in air pressure on a flight can push liquid out of a bottle that has a lot of headroom, and a leak in a bag is easier to deal with if it is contained. When the bottle is empty, rinse nothing down the sink. Empty plastic bottles can generally go into household plastic recycling once they are fully drained, but check your local council guidance, because rules on small bottles and nozzles vary by area.

Coil and mesh tech: matching the liquid to your hardware

The liquid is only half of the pairing. A high-VG shortfill like this one wants a coil that is built to handle thick liquid, and the main choice is between mesh coils and standard round-wire coils.

Mesh coils use a flat sheet of heating material pressed against the cotton instead of a round wire wrapped around it. The large surface area heats the liquid evenly, wicks quickly and avoids the hotspots that give a burnt taste. For a thick liquid they are the safer choice. Typical mesh coils for sub-ohm tanks sit between 0.15 and 0.4 ohm and are rated for roughly 40 to 80 watts. Mesh coils for refillable pod kits are usually 0.6 to 0.8 ohm and are rated for about 15 to 30 watts.

• Sub-ohm tank with mesh coil, 0.15 to 0.4 ohm: run at the lower to middle part of the printed wattage range for the best balance of flavour and coil life
• Pod kit with mesh coil, 0.6 to 0.8 ohm: a good match for 3mg to 6mg and for people who want something between a mouth-to-lung and a full direct-to-lung draw
• Round-wire coil, 0.5 to 1.0 ohm: will work, but go slowly at first because thick liquid can take longer to reach the wire
• High-resistance coils, 1.0 ohm and above, designed for nicotine salts: not recommended for a high-VG liquid. They wick too slowly and are prone to dry hits

Always check the wattage range printed on the coil, and start at the low end. Power set above the range shortens the life of the coil and produces a harsh, scorched taste that can ruin a good liquid.

Priming is the step most people rush. Before you fit a new coil, drip a few drops of liquid directly on the cotton through the wicking holes, fill the tank, and then leave it to sit for five to ten minutes. Take a couple of gentle puffs without pressing the fire button hard, so the cotton can finish soaking. A coil that is fired dry will burn within a few seconds and never recovers.

Coil life depends on the liquid. With a fruit or ice flavour you can expect around one to three weeks of regular use. Sweeter dessert profiles leave sugar deposits on the coil and shorten that, so a change after a week or ten days is normal. If the flavour fades while the tank is still full, change the coil before you assume the liquid is at fault.

Battery and charging for the device you pair it with

The liquid itself does not need charging, but the device you vape it in does, and battery choice affects how well a shortfill performs. Mismatched power is a common reason people think a liquid tastes wrong.

• Refillable pod kits: usually have a built-in battery between about 500mAh and 1,500mAh. These suit low to mid power and are charged over USB-C. A larger battery lasts longer between charges but is not necessarily more powerful
• Box mods with removable cells: run on one, two or three 18650 or 21700 cells. A 21700 cell typically holds 4,000mAh to 5,000mAh, and an 18650 holds around 2,500mAh to 3,500mAh. These give the headroom needed for sub-ohm coils at 40 to 80 watts
• Built-in battery sub-ohm kits: sit in between, with batteries typically in the 1,500mAh to 3,000mAh range

If you use removable cells, use cells from a reputable seller and check the continuous discharge rating. A sub-ohm coil pulls a lot of current, and a cell with too low a rating can overheat. Cells with a torn or damaged wrap are not safe to use. Carry spare cells in a plastic case, never loose in a pocket or bag where they can touch keys or coins.

Charging practice is simple and worth following. Use the cable supplied with your device or a good-quality replacement. Do not charge a vape under a pillow or on a sofa, and do not leave it charging overnight on a flammable surface. If a battery gets hot, swells or smells odd, stop using it. Higher power draws batteries down faster, so a sub-ohm session at 50 watts will empty a small pod battery much more quickly than the same session at 20 watts.

When a device or cell reaches the end of its life, do not bin it with ordinary rubbish. Vape devices and batteries are electrical waste and should go to a proper drop-off point. Many household waste recycling centres accept them, and most large supermarkets and electronics retailers have battery recycling points. Single-use vapes were banned in Great Britain from 1 June 2025, which is one reason refillable kits and shortfills have become the default choice, and it also means any old disposable you have should go to a recycling drop-off rather than a bin. Remove removable cells first and recycle them separately.

Nicotine strength guidance

The most important decision with a shortfill is the strength you mix to. The UK limit on nicotine-containing e-liquid is 20mg/ml, and the same cap applies to what you buy in a nicotine-containing product such as a pre-filled disposable pod. That limit exists because high-strength liquids are meant for low-power, mouth-to-lung devices. A shortfill is made for different hardware, so the usual range is far lower.

• 0mg: no nicotine. The right choice if you vape purely for flavour, if you are completing a step-down, or if you never smoked and have no business adding nicotine. Needs no shots
• About 2mg: a light option for people who have already reduced their intake and use a big airflow tank
• 3mg to 3.6mg: the most common mixed strength for sub-ohm tanks and open-airflow pod kits. A gentle hit that suits regular vapers who are not heavy users
• 5mg to 6mg: for people who are stepping down from cigarettes or from stronger liquids, or who use a restricted draw. Firmer hit, and you will often use less liquid per day

If you are coming from nicotine salts at 10mg to 20mg in a small pod kit, 6mg is a sensible starting point in a sub-ohm device. Because the draw is longer and more airy, you absorb a similar amount of nicotine across the session as you did with a stronger liquid in a smaller device. If you feel dizzy, queasy or jittery, that is a sign the strength is too high for you and you should drop down. If you still crave nicotine soon after finishing a tank, the strength may be too low, or you are drawing at too low a power.

Nicotine is addictive, and vaping is not risk-free. NHS guidance describes vaping as far less harmful than smoking, but it is meant for adult smokers who want to quit and is not for people who have never smoked or for anyone under 18. If you want help moving away from cigarettes, a local stop smoking service can give structured support, and you can combine that with vaping if you choose.

The easiest way to build a step-down plan is to hold your strength for a couple of weeks, drop by one step, hold again, and continue until you reach 0mg. Because a shortfill lets you pick a strength rather than being tied to what a manufacturer packages, it is easy to take small steps.

Who Nexus 100ml Shortfill is for, and who should look elsewhere

The shortfill format suits some people far better than others, and it is worth being clear about both sides.

It is a good fit if:

• You already own a refillable tank or pod kit and are comfortable filling it
• You vape often enough that 10ml bottles disappear quickly and cost adds up
• You prefer to choose your own strength and be able to lower it without changing brand or flavour
• You enjoy high-VG, cloud-friendly vaping with a sub-ohm or open-airflow setup
• You want a single flavour to last for weeks rather than days

It is probably not the right choice if:

• You use a closed-pod system that takes only branded pre-filled pods. The shortfill will not fit
• You want the simplest possible set-up with nothing to measure, mix or fill. A refillable kit with ready-made 10ml nicotine salt liquid is simpler
• You vape very occasionally. A large bottle can sit unused for a long time, and e-liquid has a limited shelf life once opened and mixed
• You are new to vaping and have no device yet. You will need a compatible kit first, and it makes sense to start with an easy pod kit before moving to a sub-ohm tank
• You need a high nicotine hit in a tiny, discreet device. Higher-strength salt liquids in small kits are made for that
• You are under 18, or you have never smoked. Vaping is for adult smokers who want an alternative

It also suits people who are leaving disposables behind. With single-use vapes banned in Great Britain, many former disposable users are looking at refillable kits. For those people the main adjustment is that a shortfill is not plug and play: you have to fill the tank, learn to prime a coil and maintain the kit. A pod kit with a 0.6 to 0.8 ohm mesh coil is the easiest bridge, and you can mix to 3mg or 6mg depending on how much nicotine you were used to.

Finally, if you are buying as a gift for someone else, keep in mind that the product must only be sold to adults, and a nicotine-free bottle is the kind of present that works only if the recipient already has a device that takes it.

How to use Nexus 100ml Shortfill step by step

Mixing and filling is easy once you have done it once. Work through it in order and the process takes about two minutes.

• Step 1, check the numbers: read the label for the fill volume and bottle size, then decide on your target strength using the sums earlier on this page. Buy the right number of 10ml nicotine shots
• Step 2, wash your hands and clear a surface: nicotine on skin is absorbed, so work over a tray or a piece of kitchen roll and keep children and pets out of the room
• Step 3, open the bottle: twist off the cap and pull out the nozzle if it comes out separately. Keep the cap and nozzle on a clean surface
• Step 4, add the shot or shots: pour in the nicotine shot slowly. Do not overfill. If you have chosen to vape at 0mg, skip this step
• Step 5, close and shake: refit the nozzle and cap tightly and shake the bottle firmly for around 30 seconds. Rest it for a few minutes and shake again
• Step 6, fill your tank: follow the fill instructions for your device. Tilt the tank slightly, squeeze the bottle gently and stop before the liquid reaches the top. Never fill over the central airflow tube
• Step 7, wait before you vape: give a new coil five to ten minutes to soak before the first puff
• Step 8, take your first puffs gently: use a few short draws at a low setting to confirm the coil is wetting properly, then move up to your usual power

A couple of habits help. Wipe the nozzle after each fill so that sticky liquid does not build up in the thread. Keep the bottle upright and capped between fills. Label the bottle with the strength and the date you mixed it, because once the shots are in you cannot tell the difference by sight.

If you do not use the whole bottle in a few weeks, that is fine. Keep it somewhere cool and dark with the cap tight. For liquids that have been mixed with nicotine, flavour is usually at its best in the first two to three months, after which it can dull and darken slightly. If you vape slowly, consider mixing only half the bottle at a time: pour out the amount you want to treat into a separate clean bottle and add one shot to that.

Troubleshooting common problems

Most problems with a shortfill come from a handful of causes, and almost all of them are fixable in a minute or two.

• Burnt or harsh taste: the coil is either dry, worn out or run above its rated power. Lower the wattage, let the tank sit full for a few minutes, and if it persists change the coil. Sweet liquids will cause this sooner than lighter fruit flavours
• Dry hits: the cotton is not getting liquid quickly enough. Prime the coil properly, keep the tank above a quarter full, use a lower power and make sure the airflow is not so tight that the coil overheats. High-resistance coils with a thick liquid also cause this
• Gurgling or spitting: the coil is flooded. Take out the tank, blow gently through the mouthpiece to clear the airflow and leave it for a minute. A slightly higher power can also help to clear excess liquid
• Leaking from the tank: check that the coil is screwed in firmly and that the tank seals are seated. Do not overfill, and store the tank upright. Changes in temperature and altitude can push liquid out, so empty the tank before a flight
• Flat or weak flavour: usually a tired coil, or palate fatigue after vaping one flavour all day. Change the coil and try a different flavour for a day. A newly mixed bottle can also benefit from resting overnight
• Throat feels too harsh: the nicotine strength may be too high for the device. Lower the strength by mixing with fewer shots next time, or open the airflow up. Lower wattage can also soften the hit
• No hit at all or craving returns quickly: the strength may be too low, you might have forgotten to shake after adding the shot, or you are using very low power. Check your mixing sums and shake again
• Liquid leaking from the bottle nozzle: the nozzle may not be seated properly. Remove it, wipe the thread and refit it firmly. If there is a crack in the bottle, stop using it and contact us
• Sticky residue on the device: wipe it with a damp cloth and dry it. Do not use solvents on plastic parts

If a device will not fire at all, check the battery level first, then clean the contact between the tank and the battery with a dry cotton bud. If the problem remains, try a different coil to isolate whether the coil or the device is at fault. For anything involving a swollen, hot or damaged battery, stop using the device straight away and recycle it at a drop-off point.

If the bottle itself seems faulty on arrival, for example a broken seal, a cracked body or a leak, keep the packaging and get in touch with us. The returns and refund details are in the FAQs below.

Value for money and how it compares

Value in vaping comes down to cost per millilitre, how many ml you vape per day, and what else you have to buy to use the product. Shortfills are generally good value on the first measure. Buying liquid in volume is cheaper per millilitre than buying the same amount in 10ml bottles, and the saving grows the more you vape. The added costs are the nicotine shots, which are inexpensive but not free, and coils, which are a few pounds each and need replacing every one to three weeks. To get a clear picture, take the current price on the product page, divide it by the volume of liquid in the bottle, add the cost of shots if you want nicotine and compare that with what you now spend per millilitre. For most people who vape every day, the result favours the large bottle.

Here is how the format compares with the other choices.

• Against 10ml nicotine salt bottles: salts are better for small, discreet pod kits and for people who want a strong nicotine hit at low power. They cost more per millilitre and are harder to use in a big tank, where the high strength would be unpleasant. A shortfill is cheaper to run and gives denser vapour, but it needs a bigger device and more handling
• Against other 100ml shortfill ranges: established UK brands such as IVG, Ohm Boy, Doozy Vape Co and Dr. Vapes compete in the same space with similar formats and bases. Differences come down to flavour preference, sweetness, the VG ratio and the bottle fill. We are not going to claim one is simply better than another. Choose the flavour you will enjoy over weeks, and compare the fill volume rather than only the headline price
• Against refillable pods with ready-made liquid: simpler but costlier per millilitre, and often locked to one brand's pods or flavours
• Against disposables: single-use vapes are no longer sold in Great Britain, and the nicotine strength on those that were sold was capped at 20mg/ml like any other UK nicotine e-liquid. Compared with the cost and waste of replacing a disposable every few days, a refillable kit with a shortfill is cheaper and produces less waste, though it asks more of the user

There is one honest caution. If you only vape a couple of millilitres a week, a large bottle can outlast its best flavour window before you finish it, and in that case a smaller bottle makes more sense. It is also worth remembering the start-up cost: if you do not have a suitable device, you need to buy one before the saving per millilitre starts to matter.

For regular vapers using a compatible tank, Nexus 100ml Shortfill offers a lot of liquid, a free choice of strength and a low cost per millilitre. Pair it with a well-matched mesh coil, mix it carefully, store it properly and recycle the bottle, device and batteries responsibly when you are finished.
