Nexus 100ml Blue Razz Cherry Blast at a glance

Nexus 100ml Shortfill Blue Razz Cherry Blast is a fruit e-liquid sold in a 100ml bottle that is deliberately not filled to the brim. Shortfills are supplied at 0mg nicotine, which means the liquid itself contains no nicotine at all. The empty headroom in the bottle exists so that you can add one or two 10ml nicotine shots and end up at a strength you choose yourself. If you vape at 0mg, you can simply use the bottle exactly as it arrives.

The flavour pairs blue raspberry with cherry, a combination that sits firmly in the sweet, tangy fruit corner of the market. It is aimed at people who vape with a refillable tank, a pod kit that takes a larger refill, or a sub-ohm device, rather than at anyone who wants a sealed, throwaway product. Here is a quick summary of what you are buying.

• Brand: Nexus
• Format: 100ml shortfill bottle, supplied at 0mg nicotine
• Flavour: Blue Razz Cherry Blast, a blue raspberry and cherry fruit blend
• Typical fill: a part-filled 100ml bottle with space for nicotine shots (the exact liquid volume is printed on the label)
• Best suited to: refillable tanks and sub-ohm style coils
• Nicotine options: 0mg as supplied, or add 10ml nic shots to reach roughly 2mg to 6mg
• Age restriction: sold to adults aged 18 and over only

This page walks through how the product works, what to expect from the flavour, which devices and coils suit it, how to mix a nicotine strength safely, how far a bottle will realistically go, and how it stacks up against the other ways of vaping in the UK. It is written to be read as a practical guide, not a sales pitch, so you will also find the situations where this bottle is probably not the right choice.

One important note up front: because this is a bottled liquid and not a disposable, things like battery capacity, charging and coil life depend on the device you pair it with. We cover those points in the sections on devices and power so you know what to look for when choosing a kit.

How a 100ml shortfill actually works

A shortfill is simply a larger bottle of nicotine-free e-liquid that is not filled all the way to the top. In the UK, e-liquids that contain nicotine can only be sold in bottles of up to 10ml, and the nicotine strength is capped at 20mg/ml. Those rules are why large bottles of vape juice are sold at 0mg: without nicotine, the bottle size limit does not apply, so shops can sell 50ml, 100ml and even larger sizes. The nicotine is then supplied separately in a small 10ml bottle called a nic shot.

The short fill leaves a gap in the bottle. If you want nicotine, you tip a nic shot into that gap, put the cap back on, and shake the bottle well. The result is a full 100ml bottle at a lower, more vape-friendly strength. Nic shots usually come in 18mg/ml (sometimes 20mg/ml), and because they are diluted into a much larger volume, the final strength is far lower than the shot on its own.

The arithmetic is simple enough to do on your phone. Multiply the strength of your shot by the number of millilitres you add, then divide by the total volume in the bottle after mixing.

• Example A: 70ml of liquid plus one 10ml 18mg shot gives 80ml in total, so 180 divided by 80 is about 2.25mg/ml.
• Example B: 80ml of liquid plus two 10ml 18mg shots gives 100ml in total, so 360 divided by 100 is 3.6mg/ml.
• Example C: 70ml of liquid plus three 10ml 18mg shots gives 100ml in total, so 540 divided by 100 is 5.4mg/ml.

These figures are examples. Always check how many millilitres of liquid are in your bottle and how many shots it can hold, because the label on the bottle is the source of truth. If you add more shots than the bottle can physically hold, you will overflow it, and if you add fewer, you end up with a weaker mix than expected.

The big difference from a disposable vape is control. A single-use or prefilled device gives you one fixed strength, one flavour and, in the single-use case, a battery that cannot be replaced. A shortfill gives you the liquid only, and you decide the strength, the device and the coil. That flexibility is why many people move from disposables to refillable setups once they know what they like.

The flavour profile: blue raspberry meets cherry

Blue Razz is the shorthand used across the vape industry for blue raspberry, a flavour that is closer to a sweet, slightly sharp sweet-shop raspberry than to the fruit you would pick from a garden. It tends to taste bright, sugary and a little tangy. Cherry Blast adds a second layer: a rounded, sweet cherry note, more cherry sweet or cherry cola syrup than a fresh stone fruit.

Put together, you can expect a flavour that is built in three stages. We describe them below based on how this type of blend generally behaves in a tank, so your own impression may differ slightly depending on your device, wattage and how you vape.

• On the inhale: the blue raspberry usually leads, with a sweet, tart front end that you notice on the tip of the tongue.
• Mid-vape: the cherry steps forward and rounds out the sharpness, giving the liquid a fuller, candy-like body.
• On the exhale: a lingering sweet fruit finish, with the raspberry tang fading first and the cherry staying a touch longer.

The word Blast in the name suggests a punchy, high-impact fruit profile rather than a subtle one. If you like delicate, natural-tasting fruit, this is probably more intense than you want. If you like confectionery-style flavours, it is squarely in that territory. We have not described a cooling or menthol note because we cannot verify one from the product name alone, so if you want a chilled finish, look at the product description for this variant or choose a dedicated ice flavour.

Sweetness matters for coil care. Sugary fruit liquids, and especially those using sweeteners, can leave a darker residue on the coil than lighter flavours do. That is normal for this style of e-liquid and is the main reason fruit candy flavours need coil changes a little more often. We cover how to spot a tired coil in the troubleshooting section.

If you are new to blue raspberry, a useful comparison is a blue raspberry sweet or soft drink. If you are new to cherry, think cherry sweets rather than fresh fruit. Setting those expectations before your first tank helps you judge the flavour fairly instead of expecting something closer to a smoothie.

Bottle design, cap and build quality

A shortfill bottle is a simple object, but the details decide whether it is pleasant to use. Most 100ml shortfills, including this one, are supplied in a soft, squeezable plastic bottle with a narrow nozzle. The narrow nozzle is what lets you fill small tank ports without making a mess, and the soft plastic lets you control the flow with a gentle squeeze.

Three things are worth checking when your bottle arrives.

• Tamper seal: the cap should have an intact ring or seal before first opening. If the seal is broken or the bottle is leaking, contact us rather than using it.
• Nozzle fit: the nozzle should sit snugly in the neck of the bottle. A loose nozzle can pop out when you squeeze, so press it down firmly when you first open the bottle.
• Label information: the label should show the brand, flavour, volume, VG/PG ratio, a nicotine warning where relevant, a batch code and the usual age and safety notices.

Because the bottle is only part filled, you will see a lot of empty space inside it. That is intentional and is how the shot-adding process works. If you are not adding a shot, the air gap is harmless; just keep the cap closed and store the bottle upright.

The cap on e-liquid bottles is designed to be child resistant. It usually needs a firm press and twist, which can feel stiff at first. Keep it that way: e-liquids should be stored well out of reach of children and pets, and the child-resistant cap is part of the reason nicotine liquids are allowed to be sold in consumer bottles.

Plastic bottles are fine for weeks or months of storage if you treat them sensibly, but they are not permanent containers. Heat, direct sunlight and a hot car can degrade both the flavour and the plastic, so a cool cupboard or drawer is the better home. If you decant into a smaller dropper bottle for convenience, label it clearly with the flavour and the strength you mixed.

In terms of build quality, there is not much more to say than that the bottle should seal properly, pour cleanly and survive being squeezed a few hundred times. If yours does not, we want to know about it.

Choosing and mixing your nicotine strength

Because this is a shortfill, the strength is your decision. That is more flexibility than a disposable offers, but it also means you need a sensible starting point. The right strength depends on how you currently vape, how much nicotine you are used to, and what kind of device you are using.

As a rough guide, sub-ohm and high-power vaping delivers a lot of vapour per puff, so most people use lower strengths with it. Lower-power, tighter-draw setups deliver less vapour, so they usually pair with higher strengths. The ranges below are general starting points, not medical advice.

• 0mg: for people who no longer need nicotine, or who vape purely for flavour. No shot required.
• About 1.5mg to 3mg: a common range for sub-ohm tanks used by people who smoke lightly or who are tapering down.
• About 3mg to 4mg: a typical range for people moving from regular cigarettes to a mid-power tank.
• About 5mg to 6mg: for heavier smokers using tighter-draw coils or lower-wattage setups. Going higher than this with a high-power sub-ohm device can feel harsh in the throat.

If you are coming from a disposable at 20mg/ml, remember that disposables use nicotine salts, which are smoother at high strengths. A 20mg salt disposable is not directly comparable to a 6mg freebase mix in a sub-ohm tank; the sub-ohm tank delivers much more liquid per puff, so the total nicotine you actually take in can be similar even though the number on the bottle is lower. Start in the middle of the suggested range and adjust after a few days.

Mixing is straightforward.

• Wash and dry your hands, and work somewhere you will not be disturbed.
• Open the shortfill bottle and keep the nozzle somewhere clean.
• Twist the top off the nic shot, then pour or squeeze the contents into the shortfill bottle.
• Put the nozzle and cap back on tightly and shake for around 30 seconds.
• Let the mixed bottle rest for a few hours, ideally overnight, then shake again before your first fill.

Nicotine is a poison if swallowed in concentrated form and can be absorbed through skin, so wipe up any spills straight away and wash your hands afterwards. Never add more nicotine than the bottle can hold, and keep nic shots out of reach of children and pets at all times. If you are unsure about the right strength for you, a local stop-smoking service or pharmacist can help.

Devices and coil technology that suit this liquid

A 100ml shortfill is formulated to be vaped in a refillable device, and the thickness of the liquid matters. Large-bottle fruit shortfills are commonly made with a high VG (vegetable glycerine) share, often in the region of 70VG and 30PG, though you should always confirm the exact ratio on the bottle label. High-VG liquid is thicker, so it works best in tanks with wide wicking ports and coils designed for it. Low-resistance coils draw more liquid and produce more vapour, which is why shortfills and sub-ohm devices go together.

These are the main coil and device types you are likely to meet.

• Sub-ohm mesh coils: typically 0.15 to 0.4 ohms, run at roughly 40 to 80 watts. Mesh has a large surface area, heats evenly and tends to deliver strong, consistent flavour with thick liquids. This is the usual match for a 100ml fruit shortfill.
• Sub-ohm wire coils: traditional round-wire coils from about 0.2 to 0.5 ohms. They work well too, though they can be slightly less even in how they heat.
• Regular-resistance coils (about 0.8 to 1.2 ohms): better suited to thinner liquids and nicotine salts. A very high-VG shortfill can struggle to wick quickly enough in these, which can cause dry hits.
• Larger pod kits: some refillable pod devices accept thicker liquids with mesh pod cartridges. Check the manufacturer guidance for the maximum VG your pod supports.

If you are unsure what your tank supports, look at the coil head: the ohm rating and the recommended wattage range are printed on it. Staying inside that range is the single most useful habit for getting good flavour without burning the coil.

Mesh coils deserve a special mention because they are the biggest change in tank design of the last few years. A mesh coil is a flat strip of metal mesh pressed against cotton, rather than a coil of wire wrapped around it. More of the cotton touches the heating element, so more liquid is vaporised evenly, and flavour is usually crisper. For a sweet blend like blue raspberry and cherry, that translates into a cleaner fruit taste.

Before the first fill, prime a new coil by putting a few drops of liquid directly onto the cotton, then filling the tank and leaving it for five to ten minutes. This stops the cotton burning on the first puff and helps the coil last longer.

Power, batteries and charging for your kit

Unlike a disposable, a shortfill bottle has no battery of its own. The battery is part of the device you pair it with, and that device is what decides how long you can vape between charges. It helps to understand a few basics so you can choose a kit that suits this liquid and your routine.

For a sub-ohm tank, the device matters more than the liquid when it comes to battery life. Higher wattage means faster drain.

• Box mods and kits with replaceable batteries: these use cylindrical 18650 or 21700 cells, typically in the 2500mAh to 5000mAh range. They run at higher wattages and are easy to carry spares for.
• Kits with an integrated battery: commonly 1000mAh to 3000mAh. You charge them through a USB-C port, and many support pass-through use while charging.
• Small pod devices: usually 400mAh to 1000mAh. They suit lower-power vaping and are best matched with thinner liquids or a pod rated for thicker shortfill.

As a rule of thumb, a 3000mAh battery used at around 50W will give a typical vaper a full day of moderate use, though real-world results depend on coil resistance, how often you vape and the age of the battery. If you find yourself charging more than once a day, either the battery is small for your power setting or the coil is lower resistance than your device is happy with.

Charging tips that apply to almost every vape device:

• Use the cable supplied, or a quality USB-C cable and a mainstream charger.
• Do not leave a device charging unattended overnight, and never charge on a bed, sofa or other soft surface.
• Do not carry loose lithium cells in a pocket with keys or coins. Use a proper case.
• Stop using any battery that is swollen, hot to the touch, dented or has damaged wrapping.

When a battery or vape device reaches the end of its life, do not put it in household rubbish or ordinary recycling. In the UK, lithium batteries and electronic vapes should go to a household waste recycling centre or a retailer take-back point that accepts them. Many larger supermarkets and electrical shops have battery recycling bins as well, and shops that sell vapes are required to offer take-back for waste vape equipment. This keeps fire risk out of bin lorries and recycling plants.

How long a 100ml bottle lasts in real use

Disposable vapes are described in puffs, but bottled e-liquid is measured in millilitres, and the honest answer to how long a 100ml bottle lasts is: it depends on your device and your habits. We can give useful ranges, though, based on how much liquid different types of setup typically use.

Sub-ohm tanks run at higher wattage and use more liquid per puff. A moderate user on a mesh sub-ohm coil often goes through somewhere around 3ml to 6ml a day, while a heavy user may go through 8ml to 10ml or more. Pod and lower-power setups use less, often 1ml to 3ml a day.

• At 2ml a day, a 70ml fill lasts around five weeks.
• At 4ml a day, it lasts around two and a half weeks.
• At 6ml a day, it lasts around twelve days.
• At 10ml a day, it lasts about a week.

If you want to translate that into the puff counts disposables use, a rough conversion for sub-ohm vaping is that each millilitre gives somewhere in the region of 100 to 200 puffs, depending on puff length and wattage. On that basis, a 70ml fill could deliver several thousand puffs, which is in the same range as the larger disposable vapes but at a fraction of the waste, since you refill the same device. We offer this only as a guide because individual puff style varies widely.

What affects consumption?

• Wattage: every extra 10W noticeably increases how much liquid you use.
• Coil resistance: lower-ohm coils pull more liquid.
• Puff length: long draws use more than short ones.
• Nicotine strength: people on lower strengths tend to vape more often to compensate.
• Flavour fatigue: sweet fruit blends can lead to vaping more as the palate gets used to them, which is another reason to rotate flavours.

A shortfill bottle is not meant to be used as a rapid single-session product, so think of it as a stock that will see you through weeks. Keeping an eye on your own consumption for a few days will tell you whether 100ml is a month's supply or a fortnight's.

Who this bottle suits and who should look elsewhere

Every vape format suits some people and frustrates others. Here is a plain assessment of who gets the most from a bottle like this one.

It is probably a good fit if you:

• already own, or plan to buy, a refillable tank or a pod kit that takes thicker liquid;
• enjoy sweet fruit and candy-style flavours;
• want to vape at a low nicotine strength, or at 0mg, and prefer to control the mix;
• use enough liquid that a larger bottle saves money compared with 10ml bottles or disposables;
• are moving away from disposables and want less waste and more flexibility.

It may not be the right choice if you:

• do not own a refillable device and want something you can use straight from the packet. A disposable or a prefilled pod kit would be simpler;
• use a very low-power pod system that is designed only for nicotine salt liquids. The thicker shortfill may wick poorly there;
• are not comfortable measuring and mixing nicotine shots, since a wrong mix can be uncomfortably strong;
• dislike sweet flavours, in which case a tobacco or mint liquid would suit you better;
• vape very occasionally. A 100ml bottle may outlast its best-before date before you finish it.

For non-smokers and people under 18, vaping is not appropriate. Nicotine is addictive, and vapes are sold only to adults. The sensible reason to pick up a bottle like this is as an alternative to smoking cigarettes, or to vape at 0mg if you have already dropped nicotine. If you have a medical condition, are pregnant or breastfeeding, or are taking regular medication, speak to a healthcare professional before using nicotine products.

One more audience worth naming: people who have tried nicotine salts and found them too harsh at higher strengths. Freebase nicotine in a 100ml mix is generally gentler on the throat at the lower strengths used with sub-ohm tanks, which is why some people find the switch more comfortable.

How to fill, use and store your Nexus bottle

Getting good results from a shortfill is mostly about a short routine done carefully. If you follow these steps the first time, you avoid most of the problems covered in the next section.

• Step 1: Check the bottle. Make sure the seal is intact, the label shows the volume and ratio, and the batch code is visible.
• Step 2: Add nicotine if you want it. Use the arithmetic from earlier in this guide, add the shots to the bottle, shake well, and let it rest.
• Step 3: Prepare the coil. Drip a few drops onto the cotton of a new coil and let it soak while you fill.
• Step 4: Fill the tank. Open the fill port, tilt the tank, and squeeze the liquid down the inside wall, avoiding the central air tube. Stop below the maximum line and close the port.
• Step 5: Wait. Give the coil five to ten minutes to saturate before your first puff.
• Step 6: Vape at the right power. Start at the low end of the coil's recommended wattage and move up slowly until the flavour is full but not hot.

Take slow, steady draws of around three to five seconds rather than short, sharp ones. Slower puffs tend to give a cooler, fuller flavour and use less liquid. If you are used to cigarettes, a mouth-to-lung style draw works with tighter coils, while a direct-to-lung draw suits sub-ohm tanks. Do not mix the two styles on the wrong coil, as direct-to-lung on a tight coil gives little vapour and mouth-to-lung on a sub-ohm coil can be overwhelming.

Storing the bottle properly protects the flavour.

• Keep it upright in a cool, dry place away from direct sunlight.
• Screw the cap on firmly after every use.
• Avoid leaving it in a car, on a radiator or on a windowsill.
• Keep it out of reach and sight of children and pets.
• Use up a mixed bottle within a few months; the nicotine can darken the liquid over time, which is normal but a sign it is ageing.

When the bottle is empty, rinse it, let it dry, and put it in your plastic recycling if your local council accepts bottles of that type, taking the nozzle and cap off first. Check your council guidance for exactly what goes in your kerbside collection. Old coils should go in general waste, and batteries and devices go to a proper take-back point rather than in the bin.

Troubleshooting flavour, leaks and dry hits

Most problems with a shortfill setup come from the device rather than the liquid, and most are fixable in minutes. Here are the common ones and what to try.

Muted or flat flavour. This is the most common complaint with fruit liquids and is nearly always a tired coil, a low-battery device or vaper's tongue. A coil that has been in use for one to three weeks may simply need replacing, especially with sweet liquids. If the coil is fresh, switch to a different flavour for a day or two and then come back; it is a real phenomenon and it passes.

Dry or burnt hits. If the vapour tastes scorched, stop immediately. Usually the cause is one of three things: the tank is nearly empty, the coil was not primed, or you are chain vaping faster than the cotton can refill. Refill the tank, wait, and try again at a lower wattage. If the burnt taste lingers, the coil is damaged and needs replacing.

Gurgling or spitting. This is caused by excess liquid pooling around the coil, often from overfilling or from air-flow that is too tight. Remove the drip tip, blow gently through the tank to clear it, and wipe the tip. Fill to slightly below the maximum line next time.

Leaking from the tank. Check that the coil is screwed in firmly, the O-rings are in place, the fill port is closed and the tank glass or chimney is seated properly. A hairline crack in the glass will also cause leaks. Flip and store the tank upright when you are not using it.

Throat hit too harsh. This means the nicotine strength is too high for your power level, or the wattage is too high for the coil. Reduce power first. If that does not help, dilute with some of the 0mg liquid or buy a lower-strength nic shot next time.

Leaking from the bottle. If the nozzle has loosened or the bottle was squeezed in transit, mop up the spill, wash hands and check the cap. If the bottle is cracked or the seal was broken on arrival, contact us with your order number and a photo and we will arrange a replacement.

Sticky residue on the tank threads and a dark coil after a week are both signs that the setup is working as expected with a sweet liquid. Clean the tank thoroughly every couple of weeks with warm water, then let it air dry completely before refilling.

Value for money and how it compares with the alternatives

Price per millilitre is the fairest way to judge whether a bottle is good value, and in the UK, 100ml shortfills generally cost less per millilitre than 10ml nicotine bottles or per-puff than most disposables. The comparison has more nuance than the headline price, so here is a balanced look at the main alternatives.

• Versus 10ml nicotine-salt bottles: nic salts are smoother at higher strengths and suit small pod kits, which is a real advantage for lower-power vapers. But you pay more per millilitre, and you run out sooner. If you have a sub-ohm tank, a shortfill is usually cheaper to run.
• Versus disposable-style and prefilled vapes: single-use disposables have been banned from sale in the UK since June 2025, so the nearest comparison today is a prefilled pod kit or other ready-to-use device. Those are convenient and need no setup, and UK rules cap their nicotine at 20mg/ml and their tank or pod size at 2ml. A shortfill setup costs more to start because you need a device, but the running cost per day is usually lower and you can rotate flavours without replacing the whole product.
• Versus premium craft shortfills: some brands charge noticeably more for complex, multi-layered flavours with natural-tasting profiles. If you want a simple, confectionery-style blue raspberry and cherry blend, a value-range bottle like this one does the job without the premium, although a premium blend may offer more depth if you vape fruit juices all day.
• Versus other 100ml fruit shortfills: the category is crowded. Most share a similar high-VG formula and similar bottle design, so the decision often comes down to whether you like this specific flavour combination. Check the VG/PG ratio and the actual liquid volume rather than assuming two 100ml bottles contain the same amount.

Where this bottle sits well is the middle ground: an affordable fruit flavour for people who want to refill a tank rather than keep buying throwaways. Where it is less compelling is if you need a nic-salt strength of 10mg or 20mg for a small pod kit, since shortfills are not designed for that.

There are also hidden costs and savings worth noting. You will need nic shots if you want nicotine, which adds a few pounds. You will replace coils periodically, typically every one to three weeks with sweet liquids. Against that, you are not throwing away a battery and a plastic body with every purchase, and you are not paying for a puff count you do not use.

As a rough calculation, if you would otherwise buy a disposable every two to three days, switching to a refillable kit and a couple of 100ml bottles a month often brings the monthly cost down, even after the device and coils are included. Prices change, so check the current price on this page and compare per millilitre rather than per bottle.
