Nasty Liq Rainbow Candy 10ml 20mg: overview

Nasty Liq Nic Salts by Nasty Juice in Rainbow Candy is a 10ml bottle of fruit-chew flavoured e-liquid made with nicotine salts at 20mg/ml (2%). It is a refill liquid, not a ready-to-use device, so you pour it into a refillable pod kit or a similar low-power vape. For anyone who used to rely on single-use vapes and now wants something cheaper per millilitre and easier to control, this is the kind of product that makes the move straightforward.

Nasty Juice is a Malaysia-founded e-liquid brand with a long record of selling into the UK, and the Nasty Liq nic salt range is its pod-friendly line. Rainbow Candy sits at the sweet, fruity end of the catalogue. It aims at the mixed fruit chew candy profile that many vapers describe as juicy, sugary and a little tart, and it is built to be easy to vape through the day rather than as a one-off novelty.

The quick facts are below, stated the way UK rules expect them, so you can compare this bottle with others on the shelf without doing any sums.

• Bottle size: 10ml, the maximum container size for nicotine e-liquid sold in the UK
• Nicotine: 20mg/ml nicotine salt (2%), the UK maximum strength
• Flavour: Rainbow Candy, a mixed fruit chew candy profile
• Liquid type: nic salt, designed for pod kits and low-wattage mouth-to-lung devices
• Typical device pairing: refillable pod systems with 0.8 to 1.2 ohm coils
• Estimated yield: roughly 1,000 to 2,000 puffs per bottle depending on device and habits

One point of context matters for UK readers. The sale of single-use disposable vapes has been prohibited in the UK since June 2025, and the 20mg/ml nicotine ceiling that used to apply to disposables still applies to every nicotine e-liquid and refillable system sold here. A 10ml, 20mg bottle like this one therefore sits right at the legal maximum for both bottle size and strength. If you are looking for something stronger, no legitimate UK retailer can sell it to you, and any product claiming 50mg or 5% is not intended for the UK market.

The rest of this guide covers flavour, performance, the bottle itself, the devices that suit it, strength guidance, troubleshooting and value, so you can decide whether it fits your routine before you add it to your basket.

Flavour profile: what Rainbow Candy actually tastes like

Rainbow Candy is a sweet, layered fruit flavour. The idea behind it is the experience of tipping a bag of mixed fruit chews into your hand and not knowing which colour you will get next. In the vape it translates into a blend of red berry, orange and citrus, a hint of green apple or lime, and a grape-like background that rounds everything off. Flavour descriptions are always subjective, and the label does not break the recipe down note by note, so treat the following as a guide to what most people notice rather than a formula.

• On the inhale: a bright, sugary fruit hit with a slight tang. The sweetness arrives first, followed by a citrus edge that stops the flavour feeling flat.
• On the exhale: a softer, juicier fruit blend with the candy character coming through more clearly. Most people find the mixed-fruit effect is stronger when exhaling through the nose.
• Aftertaste: a light, sweet finish that fades fairly quickly. It does not usually leave a heavy, syrupy coating on the tongue.
• Cooling: there is no menthol or ice added to this flavour, so it stays warm and rounded rather than crisp.

Nic salts carry flavour a little differently from freebase liquids. Because they are normally vaped at lower wattage, the vapour is cooler and the flavour is more concentrated in each puff. That suits a candy profile well, since the sweetness is easy to pick up without needing much airflow or power. If you vape Rainbow Candy at the low end of your device's range, you will get a cleaner, juicier taste; push the power up and the sweetness tends to turn sharper and slightly sugary-hot.

Sweet liquids do tend to leave more residue on the coil, and fruit candy flavours are no exception. Sweeteners caramelise on the coil as it heats, which is why a coil that starts tasting muted or faintly burnt after a few days is a common complaint with this style of e-liquid. It is not a fault with the bottle, it is how sweetened flavourings behave, and the troubleshooting section further down explains how to manage it.

If you like fruit sweets, sherbet-style flavours or mixed berry blends, this is likely to be agreeable. If you prefer tobacco, coffee, dessert or strong menthol flavours, a candy-fruit profile will probably feel too bright, and you would do better choosing something from another family. Because it is a single flavour with no ice, it also works well as a comfortable everyday vape for people who find menthol harsh on the throat.

Performance and puff delivery

Because Nasty Liq Rainbow Candy is a liquid rather than a finished device, performance depends heavily on what it is used in. The figures below describe how this type of 10ml nic salt behaves in a typical refillable pod kit, and they are estimates, not guarantees.

Most mouth-to-lung pod devices use somewhere between 0.005ml and 0.01ml of liquid per puff, based on a standard two to three second draw at 10 to 15 watts. On that basis a 10ml bottle gives roughly 1,000 to 2,000 puffs. That is the same as around five standard 2ml pods, or several times the real-world life of a single-use vape that once claimed its own puff count. Marketing numbers on disposables were always theoretical maximums; this is a more honest, conservative range.

• Vapour production: low to moderate. Salts are designed for tight, discreet draws, not for large clouds.
• Throat hit: smooth for a 20mg/ml strength. Nicotine salts are less alkaline than freebase nicotine, so the same strength feels gentler on the throat.
• Nicotine delivery: fast. Salts are absorbed quickly, which is why they suit people moving away from cigarettes and need a satisfying hit from a small device.
• Flavour consistency: stable from the first puff to the last of a pod, provided the coil is healthy and the device is not overheating the liquid.

Several things affect how many puffs you actually get. Draw length matters: a long, slow pull uses more liquid than a short one. Wattage matters: a device running at 20 watts will go through a bottle noticeably faster than one at 10. Coil condition matters too, since a worn coil can waste liquid by leaking or gurgling. Finally, nicotine habit plays a part. People who vape frequently at 20mg/ml will use less liquid than people on lower strengths, because they satisfy the craving with fewer puffs.

In practice, a moderate vaper using a pod kit through a typical day will finish a 10ml bottle in around a week to ten days. Lighter users, such as someone who vapes mainly in the evening, can stretch it to two weeks or more. Heavier users who chain vape may find a bottle lasts four or five days. If you want to track your usage, note the date you open the bottle and the date you finish it, then use that figure to work out how many bottles to order at a time.

Bottle design, build quality and recycling

UK rules shape the physical design of nicotine e-liquid more than most people realise. A 10ml bottle like this one has to be made from plastic that is child-resistant and tamper-evident, with a narrow nozzle that lets you fill a small pod without spilling. The label must carry the nicotine content, a health warning, ingredients and a batch number, and the packaging should be sealed when it reaches you.

• Container: a 10ml plastic bottle with a fine tip, sized for pod kits whose fill ports are only a few millimetres wide.
• Cap: a child-resistant closure that needs to be pressed and turned. It can feel stiff the first time, and that stiffness is deliberate.
• Tamper-evident seal: a ring or band that breaks when the bottle is opened for the first time. If it is already broken or missing when you receive the order, do not use the liquid and contact the retailer.
• Label: shows the product name, flavour, nicotine strength, volume, the health warning and the batch details. Keep the label legible and keep the bottle in its box if you plan to store it for more than a few weeks.

The bottle is soft enough to squeeze, which helps push liquid out slowly and keeps you in control of the fill. It is also light enough to carry in a coat pocket or bag, which is one reason many people prefer 10ml sizes to larger formats. Make sure the cap is fully closed after every fill, because a loose cap in a bag can leak and nicotine liquid should never be left on skin or surfaces.

Looking after the environment is part of owning a vape product. Empty e-liquid bottles still contain nicotine residue, so avoid washing them out into the sink. The most careful route is to leave the cap off in a safe place until the bottle is fully dry, put the cap back on, and then check your local council guidance. Some councils accept small plastic bottles in household recycling, while others ask for them to go in general waste. Many vape shops and household waste recycling centres also have drop-off points for vape-related waste.

Batteries and electrical devices follow stricter rules. Pod kits, chargers and any lithium battery must never go in a household bin or recycling bag. They need to go to a proper electrical waste drop-off point, such as a council recycling centre or a retailer that offers take-back for small electricals. Doing so avoids fire risk in refuse vehicles and recovers valuable materials.

Battery and charging: matching the liquid to a device

This product is a liquid and contains no battery, so there is nothing in the bottle to charge. The battery that matters is the one in your pod kit or vape pen, and it makes a big difference to how well a 20mg nic salt performs. Choosing a sensible device is the quickest way to get the most from Rainbow Candy.

Nic salt devices are designed around low power, so they use compact batteries and charge quickly. These are the usual ranges you will see:

• 400 to 600mAh: slim pen-style pod kits. Light and pocket-friendly, and typically good for most of a day with moderate use. Expect to charge them every night.
• 800 to 1,000mAh: the mainstream choice for refillable pods. These usually last one to two days of regular use and tend to charge over USB-C in under an hour.
• 1,200 to 1,500mAh: larger pod mods with adjustable output. Good for heavy users who want to avoid daily charging, though they are less pocket-friendly.

For safe, effective charging, follow a few simple habits that apply to any lithium battery device:

• Use the cable supplied with your device or a reputable replacement, and a standard 5V USB adaptor or computer port.
• Do not charge under a pillow, on a bed or on a sofa. Keep the device on a hard, heat-safe surface.
• Avoid leaving it plugged in overnight if you can. A full charge normally takes 30 to 90 minutes.
• Stop using any device that feels unusually hot, swells, hisses or smells of burning, and take it to an electrical recycling point.
• Do not carry a device loose in a pocket with keys or coins, which can cause a short circuit.

Remember that 20mg/ml is a high strength. A more powerful battery does not give you a better experience with nic salts, because pushing the wattage up makes the vapour hotter and the nicotine hit harsher. A good pod kit with a modest battery, correct coil and stable output is better than a large device running at the top of its range. Check the manual for the recommended wattage and stay within it.

If you move between devices, keep a note of which one suits which liquid. A device that has been used with a menthol flavour may carry ghost tastes, so ideally dedicate one pod or tank to Rainbow Candy to keep the fruit flavour clean.

Coil, mesh and device compatibility

Nasty Liq Rainbow Candy is designed for mouth-to-lung (MTL) or restricted direct-to-lung vaping, which means a tight draw and a low-power coil. It is not suitable for high-powered sub-ohm tanks. The right coil is the main factor in flavour quality, so it is worth knowing what to look for.

• 0.8 to 1.2 ohm cotton or regular coils: the standard for MTL pods. They run at 8 to 15 watts, give good flavour and last well with nic salts.
• 0.6 to 0.8 ohm mesh coils: found in some newer pod systems. They heat more evenly, which can improve flavour and vapour density, but they use liquid faster and run at slightly higher wattage, usually 12 to 20 watts.
• Ceramic coils: sometimes found in older pod systems. They can be consistent but may mute flavour a little compared with cotton or mesh.

Match the liquid to the device rather than the other way around. If you push 20mg nic salt through a sub-ohm coil at 40 watts or more, the result is too much nicotine, too much heat and a harsh throat hit. That is not how salts are meant to be used. Equally, running a mesh coil at the bottom of its range with a sweet liquid can leave it tasting muted.

Check the VG/PG ratio on the label before filling. Nic salt liquids for pod kits usually sit around an even VG/PG balance, because a thinner liquid wicks quickly into small coils and avoids dry hits. A very thick, high-VG liquid can starve a small coil, while a very thin one can leak. Nasty Liq is aimed at standard refillable pods, but always confirm the ratio matches what your device manual recommends.

Priming is vital with any new coil. After fitting a new pod or coil, fill it, let it stand for 5 to 10 minutes and take a few short, gentle draws without pressing the button too hard. This soaks the cotton evenly and prevents the burnt taste that ruins a fresh coil. Replace the coil when the flavour fades, the liquid tastes burnt, or the vapour looks thin. With sweet fruit candy flavours, a coil often lasts one to two weeks rather than the three or four you might get from a plain tobacco liquid.

Always check your device is rated for 20mg nic salt and a liquid of this viscosity. Most refillable pod kits sold in the UK are, but some very low-powered or very high-powered systems are designed for different strengths.

Nicotine strength guidance: is 20mg right for you?

20mg/ml, also written as 2%, is the highest nicotine strength allowed in the UK, and it is the figure this bottle is made at. Nicotine salts are formulated to deliver that nicotine more smoothly than traditional freebase liquid, so a 20mg salt feels very different from a 20mg freebase. It is commonly used by smokers who are moving to vaping and want a satisfying experience from a small, low-power pod.

As a general guide:

• Heavy smokers (around 15 or more cigarettes a day, or the first cigarette within half an hour of waking): 20mg is a common starting point, because it matches the intensity they are used to.
• Moderate smokers (roughly 8 to 15 a day): many begin at 20mg and step down to 10 to 12mg as cravings settle. Some start straight at the lower strength if their device produces a strong hit.
• Light smokers or social smokers: 20mg is often more than needed. A 10mg salt or lower is usually enough and is gentler on the throat.
• People who have never smoked: nicotine vaping is not intended for you, and there is no reason to start.

A few practical points help avoid mistakes. If a puff makes you cough, feel dizzy or nauseous, or if your throat feels raw, the strength or power is too high. Lower the wattage, take shorter draws or step down to a lower-strength salt. Symptoms such as headaches, a racing heart or sweating can also signal too much nicotine, and the right response is to stop vaping for a while and drink water.

Do not use nic salt at a higher strength than your device is rated for, and do not mix strengths without understanding how it affects the final concentration. If you are trying to cut down, a gradual step-down approach, with a few weeks at each lower strength, is better than a sudden change. NHS stop-smoking services offer free support and advice, and many local services also provide vaping starter kits as part of a quit programme.

Nicotine is addictive. This product is for adult smokers and vapers aged 18 or over, and is not suitable for pregnant or breastfeeding women, people with serious heart conditions or anyone under medical advice to avoid nicotine. If you have concerns, speak to a GP or pharmacist before using it.

Who Rainbow Candy 10ml is for, and who it is not for

This liquid suits a fairly specific type of vaper. Being clear about that saves money and disappointment.

It is a good match if you:

• Are an adult smoker who wants to switch to vaping and needs a strong, smooth nicotine hit from a small device.
• Used single-use vapes before the ban and want a refillable alternative that costs less per puff and produces less waste.
• Enjoy sweet, fruity flavours and find menthol or tobacco liquids too harsh.
• Prefer a tight, cigarette-like draw to a loose, cloud-heavy one.
• Want a compact 10ml bottle that fits in a pocket and is easy to top up on the go.

You may want to look elsewhere if you:

• Have never smoked or vaped. Nicotine is addictive, and there is no benefit in starting.
• Are under 18. It is illegal to sell nicotine vaping products to anyone under 18 in the UK, and retailers carry out age checks at checkout and on delivery.
• Want large clouds. Sub-ohm tanks with high-VG, low-nicotine liquids are better for that, and 20mg salt is unsuitable for them.
• Dislike sweet flavours. Rainbow Candy is deliberately sugary and a tobacco, coffee or menthol option will suit you better.
• Are sensitive to nicotine or already use another nicotine product heavily. Doubling up can lead to nicotine overload.
• Are pregnant, breastfeeding or have a heart or blood-pressure condition. Speak to a healthcare professional first.

For people who are trying to stop smoking completely, a nic salt such as this one can be a useful tool, because it provides nicotine in a form that is quick and satisfying without the tar and combustion products of cigarettes. It is not risk-free and it is not a medicine, but evidence from UK public health bodies consistently shows that vaping is substantially less harmful than smoking for adults who switch fully.

If your goal is to end nicotine use entirely, plan to reduce the strength over time rather than staying at 20mg indefinitely. Many users find that after a few weeks of consistent vaping they can drop to a lower strength with no loss of satisfaction.

How to fill, use and store Nasty Liq Rainbow Candy

Filling a pod is simple once you have done it a couple of times. Take your time the first few attempts, because most leaks and flooded coils come from rushing.

• Step 1, wash your hands and clear a surface. Work over a tissue or tray, away from children and pets.
• Step 2, remove the pod from the device. Switch the device off or take the pod out entirely before filling.
• Step 3, open the fill port. Most pods have a silicone plug on the side or underneath. Pull it back gently without tearing it.
• Step 4, press and twist the bottle cap. The child-resistant cap needs pressure while you turn it. Remove it and the nozzle is ready.
• Step 5, fill slowly. Squeeze the bottle gently and fill to just below the maximum line. Do not fill into the central air tube.
• Step 6, close the port and wipe the pod. Push the plug back fully and wipe any excess from the outside.
• Step 7, wait 5 to 10 minutes. This lets the cotton absorb the liquid before you vape.
• Step 8, take a few gentle primer puffs. Then switch to your normal draw.

For the draw itself, a slow two to three second pull into the mouth, a brief pause, then an inhale into the lungs works well with nic salts. Short, light draws keep the coil cool and the flavour clean. Avoid chain vaping, which can overheat the coil and burn the sweet liquid.

Storage matters more than it seems. Keep the bottle upright, in a cool, dark place away from direct sunlight and radiators. Heat and light break down both nicotine and flavourings, darkening the liquid and dulling the taste. Close the cap fully after each use, and store it out of reach of children and pets. Nicotine liquid is poisonous if swallowed or absorbed through skin, so wipe any spill immediately and wash skin with soap and water.

Most e-liquid has a shelf life of around 12 to 24 months if kept sealed, but once opened it is best used within a few months. Check the batch information on the label, and discard any liquid that smells off, has separated or has changed colour dramatically. Nic salts naturally darken slightly with age, which is normal and does not mean the liquid is unsafe, but a very dark, bitter-smelling liquid should be replaced.

Troubleshooting common problems

Most problems with nic salt liquids come down to the coil, the fill or the power setting. Here is how to diagnose the usual ones.

• Burnt or acrid taste: the coil is dry or worn. Prime a new pod properly, avoid chain vaping and replace the coil if the taste persists. Sweet liquids gunk coils faster, so a change after one to two weeks is normal.
• Weak or muted flavour: usually coil build-up. Try a fresh pod, and check you have not been vaping a menthol flavour in the same tank, which can leave ghost tastes. Also check the device battery, because a low battery can reduce output.
• Leaking from the pod: often caused by overfilling, a loose plug or a cracked pod. Fill below the maximum line, press the plug in fully and inspect the pod for cracks. Temperature changes, such as moving from a cold car to a warm room, can also cause minor weeping.
• Gurgling or spitting: the coil is flooded or the airflow is blocked. Remove the pod, blow gently through the mouthpiece to clear excess liquid and wipe the connection contacts.
• Harsh throat hit: the wattage is too high, the draw is too long or the strength is above what you need. Lower the power, take shorter puffs, or step down to a lower-strength salt.
• Dry hits: a puff that tastes hot and papery means the coil is not getting enough liquid. Refill, prime the pod and make sure the fill level is above the coil window.
• Device will not fire: check the battery, clean the contacts with a dry cotton bud, and make sure the pod is seated correctly. If the problem continues, contact the device manufacturer.
• Vape tongue: a temporary loss of taste for a particular flavour. Switch to a different flavour for a day or two, drink water and avoid heavy smoking or very sweet foods.

If a bottle arrives damaged, leaking or with a broken seal, do not use it. Contact the retailer with your order number and a photo so the issue can be put right. Likewise, if the liquid smells wrong or tastes unusual from the very first fill, stop using it and report the batch number on the label.

If you ever feel unwell after vaping, such as dizziness, chest tightness, or persistent nausea, stop and seek medical advice. If liquid is swallowed or gets in the eyes, treat it as an emergency and contact NHS 111 or 999, or the National Poisons Information Service through your doctor.

Value for money

Value in vaping is mostly a question of cost per millilitre and how that translates into time. A 10ml bottle is the standard UK size for nicotine e-liquid, so the maths is easy: take the listed price of the bottle and divide it by ten to get the price per ml. As an illustration only, a bottle priced at a few pounds works out at well under 50p per ml, and the 10ml volume lasts around a week or more for a typical vaper.

Compare that with the single-use vapes that were common before the ban. A disposable that held 2ml of liquid and was thrown away after a few days usually cost several pounds, which put the real cost per ml much higher, and you also paid for the battery and plastic every time. A refillable pod kit costs more at the outset but the running costs are lower, because you only replace the coil and top up with liquid.

• Liquid: a 10ml bottle yields roughly five 2ml pod fills, which is more liquid per pound than most pre-filled alternatives.
• Coils or pods: replaceable and usually sold in multi-packs. With a sweet flavour you may need to change them every one to two weeks.
• Device: a one-off purchase that can last years if looked after. Lithium batteries do wear out over time, so check the warranty.
• Waste: far less than a stream of single-use devices, with fewer batteries to dispose of and a recyclable bottle.

To keep costs down, buy a few bottles at a time if your retailer offers multi-buy pricing, and check whether delivery becomes free over a threshold. Store extra bottles upright in a cool place so they stay fresh. Avoid buying very large quantities in one go, since flavour does fade and nicotine does darken over many months.

It is also worth thinking about what you are replacing. For many people the real comparison is with cigarettes. At typical UK prices a pack-a-day habit costs well over £4,000 a year, whereas a vaping routine using a bottle a week and occasional coils is a fraction of that. Individual results vary, but the gap is large enough that most people who switch fully notice a clear saving.

Finally, be wary of prices that look too good to be true. Unusually cheap e-liquid from unknown sellers may be counterfeit, mislabelled or incorrectly filled. Buying from an established UK retailer, where products are checked and registered, is a safer way to get value.

How Rainbow Candy compares with the alternatives

No single liquid suits everyone, so here is an honest comparison of how Nasty Liq Rainbow Candy sits against other common options.

• Against other 10ml 20mg fruit-candy salts: several brands sell rainbow or fruit-chew flavours in the same bottle size and strength. Most are close in sweetness and tartness, and the differences come down to personal preference. Nasty Liq tends to lean on a juicy fruit mix rather than an intensely sour finish, though if you want a strong sherbet bite you may prefer a sourer competitor.
• Against freebase e-liquid: freebase liquids are normally sold at lower strengths and are made for higher-powered devices. They can produce larger clouds but are harsher at higher nicotine levels, and they are not a direct substitute for a 20mg salt in a pod kit.
• Against pre-filled pods: closed pods are tidy and need no filling, but they lock you into one flavour at a time and cost more per ml. A bottle of salt gives you more control and a wider choice of flavours.
• Against nicotine pouches, gum or patches: these are also useful for quitting smoking, and some people prefer them because they involve no inhalation. Vaping tends to suit people who miss the hand-to-mouth habit and the feel of inhaling.
• Against the old disposables: the single-use format is no longer legal to sell in the UK. A refillable setup with a bottle like this one is the practical replacement, with lower costs and less waste, at the price of a little more effort.

Where Rainbow Candy is less suitable: it is a warm, sweet flavour with no cooling effect, so people who like ice or menthol blends may find it too heavy over a long session. It is also single-strength in this listing, so if you want to step down to 10mg later you will need to buy a separate bottle. And like most sweet liquids it is harder on coils than a plain tobacco or menthol flavour.

Where it does well: the flavour is easy to recognise, pleasant at low wattage, and fairly forgiving of different pod devices. It does not require special equipment, and the 10ml format is easy to carry. If you try it and find the sweetness too strong, many UK retailers stock the same range in other fruit and ice flavours, so you can switch without changing device or learning a new routine.

The sensible approach is to buy one bottle, use it for a week in a clean pod, and judge it on flavour, throat hit and how well it holds up on the coil. If it fits, buy another; if not, you have lost very little and gained a clearer idea of what you prefer.
