Overview: Mod Mate by Nasty 50ML Red Rage

Mod Mate by Nasty 50ML Red Rage is a shortfill e-liquid from Nasty Juice's Mod Mate range, a line aimed at vapers who run sub-ohm tanks and mod-style kits rather than closed pod devices. You get 50ml of nicotine-free liquid in a 60ml bottle, which leaves headroom for a 10ml nicotine shot if you want to add strength. That format, a large bottle at a low price per ml with the nicotine decision left to you, is the main reason shortfills remain popular with UK vapers who vape every day.

Red Rage is the flavour, and the name points to a red-fruit profile: sweet, juicy and easy to vape through a full tank without turning heavy or sickly. The Mod Mate name tells you the hardware this liquid is built around. It is a high-VG formula that suits the wide wicking ports of sub-ohm coils, so it feeds into the cotton or mesh quickly and produces the dense, cool vapour that larger devices are designed for.

This guide covers what you need to know before buying: the format and specifications, how the flavour behaves, how it performs in different kinds of kit, how to choose a nicotine strength, how to mix and fill it, what to do when something goes wrong, and how it compares on value with similar shortfills and with other ways of vaping. Where we describe how a product category usually behaves rather than a measured figure for this exact bottle, we say so, so you can check the label before you rely on it.

• Format: 50ml shortfill in a 60ml bottle, supplied at 0mg nicotine
• Suited to: sub-ohm tanks and mod-style kits, not tight-draw pod kits
• Flavour direction: red fruit, sweet and juicy
• Nicotine: add your own 10ml shot, or vape it at 0mg
• Age restriction: adults aged 18 and over only

Specifications and format at a glance

A shortfill is simply a bottle that is deliberately not filled to the top. In the UK, e-liquid containing nicotine cannot be sold in bottles larger than 10ml, so manufacturers sell larger volumes of nicotine-free liquid and leave space in the bottle for you to add nicotine yourself. The Mod Mate 50ml Red Rage follows that model: 50ml of 0mg liquid in a 60ml bottle, with the extra 10ml reserved for a standard nicotine shot.

Shortfills in this style are normally built on a high-VG base, typically around 70% vegetable glycerine and 30% propylene glycol. Always confirm the exact ratio printed on the bottle and the box, because ratios can differ between ranges and batches. A high-VG blend is thicker, which is why it pairs with sub-ohm coils that have large wicking holes, and why it gives denser vapour and a smoother, softer throat feel than a PG-heavy liquid at the same strength.

The numbers below are the ones that matter when you are deciding whether this bottle suits your setup and how much you will use.

• Liquid volume: 50ml of e-liquid in a 60ml bottle
• Supplied nicotine strength: 0mg/ml (nicotine-free)
• Typical VG/PG balance: high-VG, commonly 70VG/30PG, confirm on the label
• With one 10ml 18mg shot: 60ml at 3mg/ml
• With one 10ml 20mg shot: 60ml at roughly 3.3mg/ml
• Compatible hardware: sub-ohm tanks, mesh-coil tanks, rebuildable tanks and low-resistance refillable pod kits
• Tank fills per bottle: a UK-market tank holds a maximum of 2ml, so a full 60ml bottle works out at around 30 tank fills
• Legal limit for nicotine strength: 20mg/ml maximum on any UK nicotine e-liquid

Because the bottle is a shortfill, it is shipped without nicotine. If you want a nicotine shot, you buy it separately, and it must be a 10ml bottle at no more than 20mg/ml to comply with UK rules. Nasty Juice does not change the underlying rules, and neither does any retailer, so if you see a 50ml bottle advertised as already containing nicotine at a meaningful strength, treat it with suspicion.

Flavour profile: what Red Rage tastes like

Red Rage sits in the red-fruit family. In practice that means a sweet, juicy fruit character led by berry-style notes, rounded out by the smooth sweetness that a high-VG base naturally gives. Flavours in this category are built to be easy to vape for long sessions, so you should expect a clear, recognisable fruit impression on the inhale and a softer, slightly sweeter finish on the exhale rather than anything sharp or medicinal. The exact tasting notes are set by the manufacturer, so read the product listing and the bottle for the official description.

Fruit-forward liquids like this tend to show their character in layers. The first impression is usually the brightest and sweetest, a quick hit of ripe red fruit. A few seconds later the sweetness settles and the fruit becomes rounder and more candy-like or syrupy, depending on your coil temperature. Vaping a little warmer pushes the sweetness forward and thickens the flavour. Vaping cooler keeps the fruit crisper and lighter.

Mod Mate liquids are made for people who vape a lot, so the flavour is intended to hold up across a day rather than fatigue quickly. That is a design aim common to this class of shortfill, and it is not a guarantee, because every vaper tolerates sweetness differently. If you find sweet flavours tiring, rotating between a fruit liquid like Red Rage and something drier, such as a tobacco or menthol profile, helps prevent what vapers call flavour fatigue or vaper's tongue.

A few things influence how much flavour you get from the same bottle:

• Coil type and age: a fresh mesh coil gives the clearest flavour, while a tired coil dulls it
• Power setting: too low and the flavour is thin, too high and it turns hot and flat or burnt
• Airflow: a tighter airflow concentrates flavour, while a wide-open draw gives more vapour and a softer taste
• Nicotine shot: adding a shot slightly changes the character, adding a little peppery warmth in the throat
• Steeping time: letting a mixed bottle rest can smooth rough edges and let the fruit blend

If you want a lighter, cooler fruit experience, aim for a lower wattage and a slightly tighter airflow setting. If you want a bolder, sweeter result, step the power up a few watts within the coil's printed range, but do not go past it.

Performance and vapour delivery

Performance with a shortfill depends on three things working together: the liquid, the coil and the power setting. Because this is a high-VG liquid, it is built for direct-to-lung vaping, where you inhale straight into the lungs through a wide airflow, rather than mouth-to-lung vaping with a tight draw. In a suitable sub-ohm tank, you should expect a dense cloud, a cool and smooth inhale, and a mellow throat hit at the lower nicotine strengths this style of liquid is meant for.

Vapour production is where high-VG liquids earn their reputation. VG creates the visible clouds and the soft, round sensation in the mouth, and the larger the airflow and coil surface, the more of it you get. That also means more liquid use. A sub-ohm setup on a 50ml bottle will usually burn through it faster than a pod device would, so plan your supply accordingly. Heavy daily users often finish a 50ml bottle in a few days to a week, while lighter users may take two weeks or more.

Wicking is the other half of the equation. A thick liquid needs coils with large wicking holes so that it can reach the cotton fast enough to keep up with your puffs. If the liquid cannot feed quickly, you get dry hits and a burnt taste. This is why matching hardware matters as much as the bottle itself.

• Direct-to-lung kits: sub-ohm tanks with coils from around 0.15 to 0.4 ohm, run at power ranges set by the coil maker, suit this liquid well
• Mesh coils: broad heating surface and large intake, which tends to give quicker flavour ramp-up and less chance of dry hits with thicker liquid
• Low-resistance pod kits: refillable pods with 0.6 to 1.0 ohm mesh coils can usually handle high-VG liquids, but check the manufacturer's guidance first
• Tight mouth-to-lung pods: not recommended, since a thick liquid can struggle to wick through very small ports

Throat hit is a trade-off with vapour volume. The more airflow you open up, the cooler and smoother the vapour feels, and the less throat hit you get. If you add a 3mg nicotine shot and vape at low power, you will notice a gentle throat hit and a satisfying hit of sweet fruit. If you vape at 0mg, the throat sensation is essentially absent and the focus is entirely on the flavour and the vapour.

Design and build quality of the bottle

The packaging matters more with a shortfill than with a small nic salt bottle, because you will be handling it repeatedly: opening it, adding a shot, shaking it, and refilling a tank from it over weeks. The Mod Mate range uses a 60ml plastic bottle with a fine-tipped nozzle, designed to deliver liquid into the small filling ports on tanks without drips or spills. The tip is the part to check first, because it lets you fill neatly into most top-fill and side-fill tanks.

The bottle is made of squeezable plastic so that you can control the flow. A good habit is to squeeze gently and slowly rather than pumping the bottle hard, which can send liquid shooting out or draw air back into the chamber and cause a glug. The cap is a child-resistant design, which is a legal requirement for refill bottles in the UK, and it takes a few seconds to learn: press down, then turn. Keep it that way. Do not try to defeat or loosen the mechanism.

One practical point about shortfill bottles is the extra headspace. That empty 10ml is there on purpose, so do not top the bottle up with other liquid unless you are adding a nicotine shot. When you add the shot, the bottle will be almost full, so avoid shaking with the cap loose, and always close the cap firmly before mixing.

• Bottle size: 60ml with 50ml of liquid supplied
• Nozzle: narrow tip for filling small tank ports with less mess
• Cap: child-resistant, press-and-turn style
• Labelling: UK-style warnings, ingredients, batch information and nicotine statement
• Material: plastic, which can usually go into household plastic recycling once empty and rinsed, though you should check your local council's guidance on e-liquid containers

Look at the label before you use any bottle. The batch number and the best-before date should be clear and legible, and there should be a nicotine statement, even if the figure is zero. If a label is missing, smudged or inconsistent, contact the retailer before opening it. Store the bottle upright, away from direct sunlight and heat sources, and out of reach of children and pets.

Battery and charging: matching the right device

Strictly speaking, an e-liquid has no battery, so this section is about what powers it. A shortfill needs a device with enough battery capacity and output to drive a sub-ohm coil, and that is a very different requirement from a small pod stick. Getting this part right affects both your enjoyment and your safety.

Sub-ohm kits typically fall into two groups. The first is the integrated-battery kit, where a rechargeable cell is sealed inside the device and charges over USB-C. These commonly carry anywhere from about 1,000mAh to 3,000mAh. The second is the removable-battery mod, which uses one or two 18650 or 21700 cells that you charge in a separate charger or in the device. Higher-wattage kits drain faster, and if you vape on a 0.2 ohm coil at 50 to 70 watts, a modest internal battery may only last part of a day.

Charging is simple, but it deserves care. Always use the cable that came with the device or a reputable replacement, plug it into a standard wall adaptor or computer port rather than an unknown fast charger, and do not leave a device charging unattended overnight on a soft surface. If you use removable cells, keep them in a plastic case when they are not in the device and never carry them loose in a pocket with keys or coins.

• Integrated kits: USB-C charging, simpler to use, battery life depends on wattage
• Removable-cell mods: swap in a spare charged cell, but use only cells that match the device specification
• Typical charge time: from one to three hours for most built-in batteries, depending on capacity and charger
• Signs to stop using a battery: swelling, heat while idle, a damaged wrap, or unusual smells

When a battery or device reaches the end of its life, do not put it in the household bin. Lithium cells can start fires in refuse lorries and recycling plants. Take batteries and old devices to a battery recycling point, which you will find in many supermarkets and household waste recycling centres, or hand them in at a vape shop that offers take-back. UK retailers that sell electrical products, including vape devices, are required to offer a way to return old equipment, so ask when you buy a new kit. Empty e-liquid bottles can usually be disposed of through plastic recycling once rinsed, but check your local council's rules.

Coil and mesh technology that suits this liquid

The coil is where liquid becomes vapour, and the coil you choose determines whether a thick shortfill like Red Rage tastes clean or struggles. Two coil designs dominate sub-ohm tanks today: traditional round-wire coils and mesh coils. Both can work with this liquid, but they behave differently.

Round-wire coils wrap resistance wire around a cotton wick. They are compact, and when new they can give a sharp, focused flavour. However, their heating surface is relatively small, so a thick liquid can sometimes saturate the wick unevenly at high power. Mesh coils replace the wire with a flat or cylindrical sheet of metal mesh with a large contact area against the cotton. That broader surface heats quickly and evenly, which is why many vapers find mesh coils produce a fuller flavour sooner and handle high-VG liquids with fewer dry hits.

Resistance is measured in ohms. A lower resistance draws more power from the battery and produces more heat and more vapour. For a high-VG shortfill like this one, sensible choices usually fall into a few ranges:

• 0.15 to 0.25 ohm: high-wattage, big clouds, fast liquid use, suits experienced direct-to-lung vapers
• 0.3 to 0.5 ohm: a balanced range of flavour, vapour and liquid use, suited to most sub-ohm users
• 0.6 to 1.0 ohm: found in many refillable pods, a lighter draw with tighter airflow and lower consumption

Every coil has a recommended power range printed on its side or its packaging, for example 40 to 60 watts. Stay inside that range, preferably in the lower to middle part, because running a coil beyond its range burns the cotton and ruins flavour. After fitting a fresh coil, let it soak for five to ten minutes before the first puff, and take a few gentle, short pulls at a low wattage to wet the cotton fully. This priming step prevents most of the burnt hits that new users blame on the liquid.

Coil life depends on how you vape. Sweet, fruit-heavy liquids tend to build residue on the coil, since sugars and sweeteners caramelise, so expect to replace coils a little more often than you would with a tobacco flavour. A change every one to two weeks is typical for regular use, and sooner if the flavour begins to taste burnt or muted.

Nicotine strength guidance

Red Rage ships at 0mg, so the nicotine decision is entirely yours. That is a benefit if you know what you want and a source of confusion if you do not. The principle is simple: sub-ohm vaping delivers a lot of vapour per puff, so you usually need a much lower strength than you would use in a small pod kit or a nic salt liquid.

UK law caps nicotine in e-liquid at 20mg/ml, and the same cap applies to nicotine shots and to the refillable and rechargeable vape devices you use with them. Single-use, non-rechargeable disposable vapes have been banned from sale in the UK since 1 June 2025, so the rechargeable and refillable route is now how most adults vape. Shortfill bottles and shots are the way most people reach a strength between 0 and 6mg without buying a dozen small bottles.

Here is how the mixing works. A standard 10ml nicotine shot at 18mg/ml mixed into a 50ml 0mg shortfill gives 60ml at 3mg/ml. A 20mg/ml shot gives roughly 3.3mg/ml. Two shots would push you towards 5 to 6mg/ml, but a 60ml bottle will not hold the extra 10ml, so you would need to pour out some liquid or transfer it into a larger empty bottle.

• 0mg: for people who no longer need nicotine or who vape purely for flavour
• 3mg: a common starting point for light to moderate smokers moving to sub-ohm vaping, and the strength you get with one shot
• 6mg: suited to heavier former smokers, though the throat hit rises noticeably with high power or tight airflow
• Above 6mg: rarely comfortable in a sub-ohm setup, and usually better handled with a nic salt liquid in a pod device

If you are coming from cigarettes, a rough guide is that a pack-a-day smoker often lands around 3 to 6mg in a sub-ohm kit, while someone smoking a few a day may be satisfied at 0 to 3mg. These figures are indicative only and are not medical advice. Everyone's tolerance differs, and your needs usually fall over time. If you feel dizzy, nauseous or get a headache after vaping, you may have taken too much nicotine and should stop, drink water and lower the strength next time.

If you are not a smoker, you do not need nicotine, and a nicotine-free bottle is the sensible way to enjoy the flavour. Vaping is intended for adult smokers who want an alternative, and it is not recommended for people who have never smoked.

Who Mod Mate Red Rage is for

This product suits a fairly specific kind of vaper, and being honest about that saves you money. If you already own a sub-ohm tank or mod kit, vape most days, and like a sweet fruit flavour, it is a straightforward and economical choice. If you are brand new to vaping and own only a small pod stick, a shortfill is likely the wrong format for you today.

The people who tend to get the most from a shortfill like this are those who value volume and flexibility. A single 60ml bottle will last a long time for a moderate user, and the ability to set your own nicotine strength is useful when you are trying to step down gradually. It also appeals to vapers who enjoy the hobby side of things: swapping coils, adjusting airflow and tuning wattage to dial in flavour.

• Good fit: adult smokers or former smokers who use a sub-ohm kit and prefer fruit flavours
• Good fit: vapers who want to keep nicotine low, or who vape at 0mg for flavour only
• Good fit: people who go through a lot of liquid and want a lower cost per ml than small bottles
• Less suited: anyone using a very tight mouth-to-lung pod kit
• Less suited: people who need high nicotine strengths of 10 to 20mg, who are better served by nic salt liquids
• Not suitable: anyone under 18, non-smokers, and people who are pregnant or have heart conditions without taking medical advice first

It is also worth being realistic about lifestyle. A sub-ohm device is larger than a pod stick, produces more vapour and needs more upkeep. If you vape mostly outdoors or at home, that is not an issue. If you need something discreet in a shared office or on public transport, where vaping is usually not permitted anyway, a pod kit will serve better.

If you are trying to stop smoking, speak to your pharmacist or GP, or contact your local stop-smoking service. Many areas in the UK offer free support, and combining a vape with that support improves the chance of success.

How to use and mix your shortfill

Preparing a shortfill takes about two minutes. The steps are the same for every 50ml bottle in a 60ml container, and following them in order avoids spills and uneven nicotine.

• Step 1, wash and dry your hands. Nicotine can be absorbed through the skin, and liquid on your fingers makes the bottle slippery.
• Step 2, open the bottle. Press down and turn the child-resistant cap, then lift out the nozzle insert if it has one separate from the cap.
• Step 3, add your shot if you want one. Squeeze the full contents of a 10ml nicotine shot into the bottle. If you are staying at 0mg, skip this step.
• Step 4, close it properly. Refit the nozzle and the cap and check that both are seated firmly.
• Step 5, shake well. Shake for about 30 to 60 seconds so that the nicotine blends with the base liquid.
• Step 6, let it rest. Leave the bottle upright for a day or two if you can. This is optional, but it helps the flavour settle and any air bubbles clear.
• Step 7, fill your tank. Fill slowly, and never above the max line. Leave the airflow closed while filling to avoid flooding the coil.
• Step 8, prime the coil. Wait five to ten minutes, then take a few gentle puffs at low power before you use your normal wattage.

Keep a few more habits in mind. Shake the bottle again briefly each time you use it, since nicotine can settle slightly over time. Do not mix this liquid with other flavours unless you know what you are doing, since concentrates and unrelated liquids can alter the ratio and throw off the strength. Never add anything that is not intended for e-liquid, such as essential oils or flavourings meant for food, because they can damage coils and are not designed to be inhaled.

Store the mixed bottle in a cool, dark place. A mixed bottle is ideally used within a few weeks to a few months, since heat, light and air gradually change flavour and darken the liquid. A darker colour is normal with time and nicotine, and does not automatically mean the liquid has gone off, but any change to smell or a harsh, off taste suggests it is better to replace the bottle. Keep all bottles and shots well out of reach of children and pets, and clean up spills straight away with a paper towel.

Troubleshooting common problems

Most problems that people blame on the liquid are caused by the coil, the settings or the way the bottle was prepared. These are the issues we see most often with high-VG shortfills and what usually fixes them.

• Burnt or acrid taste. This is usually a dry or scorched coil. Let a new coil soak for ten minutes, lower the wattage, take shorter puffs and replace the coil if the taste does not clear.
• Weak or muted flavour. The coil may be worn, the power may be too low, or you may be suffering from vaper's tongue. Try a fresh coil, nudge the power up within the printed range, or switch to a different flavour for a day.
• Gurgling or spitting. The tank may be overfilled or the coil flooded. Wipe the drip tip, run the tank on a lower airflow setting for a moment, and avoid filling past the max line.
• Leaking from the tank. Check that the tank is assembled with all seals in place, that the coil is screwed in firmly and that you have not overfilled it. Thin liquids leak more easily, but high-VG liquids will still escape from a loose seal.
• Harsh throat hit. Your nicotine strength may be too high for your setup, or the power is too high. Reduce the strength, open the airflow or turn down the wattage.
• Weak nicotine or no throat hit. Make sure the shot was fully mixed and that the bottle was shaken. If you are at 3mg and want more, consider a slightly higher strength, though stay within the 20mg/ml legal cap.
• Liquid appears darker than expected. A darker tone after adding nicotine or storing the bottle is normal. Only worry if the smell or taste has clearly changed.
• Bottle will not open. Child-resistant caps need a firm press and turn at the same time. Do not force or cut the cap.

If you have tried a fresh coil, a sensible wattage and a properly mixed bottle and the problem remains, check the device itself. A low battery can cause weak vapour and erratic performance, and a damaged or dirty battery contact can stop the coil firing. Clean the connection with a dry cotton bud and make sure the tank is screwed in straight.

If you suspect a fault with the liquid, such as an unusual smell, visible particles, a leaking bottle on arrival or a missing label, stop using it and contact the retailer with your order number and a photo. Do not continue vaping a liquid you have concerns about.

Value for money and how it compares

Value in vaping is mostly a question of cost per millilitre and how long a given bottle lasts. A 50ml shortfill usually costs far less per ml than a 10ml nicotine bottle, and that difference gets larger the more you vape. Even after you add the cost of a 10ml nicotine shot, the total price per ml is normally lower than buying small bottles in the same strength. Check the current price on the listing, because shortfill pricing varies from week to week.

Here is how this product compares with the other main ways to vape. These are fair, general comparisons rather than claims about specific competing products.

• Against other 50ml shortfills: established shortfill ranges from brands such as Doozy, IVG, Dinner Lady and Elux sit in a broadly similar price band. The real differences are in flavour, sweetness level and VG ratio, so the deciding factor is whether you like red fruit and whether the VG ratio suits your coils.
• Against nic salt 10ml bottles: nic salts are better for pod kits and for people who need higher strengths of 10 to 20mg. They cost more per ml and are not intended for sub-ohm tanks, whereas a shortfill gives you far more liquid and a cooler, thicker vapour.
• Against rechargeable pod devices with prefilled pods: these are simpler and more discreet, but the ongoing cost per ml is usually higher, and you are tied to one maker's pods.
• Against single-use disposables: these have been banned from sale in the UK since 1 June 2025, and in any case a refillable system with a shortfill produces far less waste and costs less over time.

The hidden costs of a shortfill setup are worth counting. You will need a nicotine shot if you want nicotine, a compatible tank, replacement coils every week or two, and batteries or a charging setup. For someone who already owns a sub-ohm kit, those are costs they would be paying anyway. For a newcomer, the entry price is higher than a basic pod stick, though the running cost is lower.

Overall, Mod Mate Red Rage is a sensible mid-market choice for adult vapers who already run sub-ohm hardware and enjoy sweet fruit flavours. It offers a large volume, flexible nicotine and a high-VG formula suited to its intended kit. It is not the right choice if you vape in a tight pod device, need a high nicotine strength or want the simplest possible setup. If you are unsure, start with a single bottle, mix it to a low strength, and give it a week before deciding whether to buy more.
