RTB Liq nic salts at VapeShopOnline: what this collection holds

This page covers RTB at VapeShopOnline, and it is a narrow, focused collection. At the time of writing it holds one product line: RTB Liq Nic Salts Box of 10. Each box contains ten 10ml bottles of nicotine salt e-liquid, the box is priced at £12.99, and it comes in 19 flavours. Every flavour listed here is sold at 10mg, and that strength is written into each variant name so you can see it before anything goes in your basket.

Those numbers shape everything else on this page. £12.99 for 100ml of liquid works out at roughly £1.30 per 10ml bottle, which places RTB Liq at the value end of the nic salt market rather than the premium end. A strength of 10mg sits in the middle of the nic salt range, which makes it a sensible fit for adults who want something gentler than 20mg but more noticeable than 5mg. The flavour list leans towards fruit and cooling profiles, with a menthol, a cola, a fruit gum and a pink lemonade for people who prefer sweeter or sharper options.

RTB Liq is e-liquid, not a device. You need a refillable pod kit or a compatible refillable tank to use it. That matters more than it used to, because single-use disposable vapes have been banned in Great Britain since 1 June 2025, and many adults who relied on them have moved to a reusable kit plus a bottle of nic salt. If that describes you, this page was written with you in mind.

In the sections below we explain what nic salt is, what can and cannot be said about the brand, how the 19 flavours group together, who the range suits, how to think about strength and how long a box lasts, which devices work with it, how it compares with other formats, what UK law says, how to spot genuine stock, and how to look after your kit and recycle it. Everything here is written for adults. Sales are strictly 18+, and orders are age verified before dispatch. UK delivery is free over £20, orders placed before 4pm are dispatched the next day, and the stock is 100% genuine.

What nic salt e-liquid is and how it differs from freebase

Nicotine salt e-liquid, usually shortened to nic salt, uses a form of nicotine that has been combined with an acid. The practical effect is that the liquid can carry a higher nicotine strength without the harsh throat hit that the same number would give in a traditional freebase liquid. Many adults find that a nic salt at 10mg or 20mg feels smoother on the inhale and satisfies them with fewer puffs than a freebase at a comparable strength.

Freebase liquids are normally sold at lower numbers, such as 3mg, 6mg or 12mg, and they are designed for larger tanks and higher-wattage devices that produce a lot of vapour. Nic salts are designed for the opposite end of the market: small, low-power kits that you draw on the way you would draw on a cigarette, with a tight pull and a modest amount of vapour. The two styles are not interchangeable. A strong salt in a high-wattage tank tends to taste harsh and disappears quickly, and a low-strength freebase in a tiny pod kit often leaves a regular nicotine user wanting more.

The main differences are easy to summarise:

• Strength range. Nic salts commonly run from 5mg to 20mg. Freebase usually stops at 12mg for everyday use.
• Device type. Salts suit pod kits and low-wattage refillable systems. Freebase suits sub-ohm tanks and mods.
• Throat hit. Salts are generally gentler at a given strength, which is why they can be offered at higher numbers.
• Vapour production. Salts are used with small amounts of vapour. Freebase is the usual choice for large clouds.
• Usage pattern. Salts are drawn in short, frequent puffs. Freebase is more often drawn in long, slow breaths.

RTB Liq sits firmly in the nic salt category. It comes in the 10ml bottle size, which is the largest size UK law allows for nicotine-containing e-liquid, and the 10mg strength puts it in the moderate part of the nic salt scale. If you are used to freebase and are moving to a small pod kit for the first time, expect the experience to feel quite different, and give yourself a few days to adjust before deciding whether the strength is right.

RTB Liq brand background and the range we stock

Many brand pages invent a story. We would rather tell you plainly what we know. RTB Liq does not publish the kind of detailed company history that some larger names put on their websites, so we are not going to dress it up with founding dates or manufacturing claims we cannot verify. What we can describe is the product as it appears in our catalogue and how it behaves in practice.

The range has one flagship line, and it is also the only line: the Nic Salts Box of 10. It is a multipack of ten 10ml bottles, sold at a single price of £12.99 regardless of flavour, in a single listed strength of 10mg. That simplicity is a point in its favour. There are no hidden price tiers between flavours, no confusing choice between 5mg, 10mg and 20mg versions of the same box, and no accessory bundle that you have to unpick. You choose a flavour and you know what the box costs.

The signature of the range is a mix of fruit, ice and a few familiar soft drink styles. Several flavours carry the word Ice in the name, which signals a cooling finish on the exhale. Others, such as Triple Mango and Kiwi Passion Fruit Guava, are multi-fruit blends, while Cola Ice, Pink Lemonade and Fruit Gum borrow from sweet shop and drinks shelf flavours. There is also a plain Menthol for adults who want a cold, minty draw without any fruit on top.

Because this is a multipack of bottles rather than a device, there is no battery, coil or hardware in the box, and no hardware warranty in the way that a pod kit would have one. What you can expect from the supplier side is that the bottles are sealed, labelled with the strength and ingredients as UK rules require, and packed in a box of ten. If any bottle arrives damaged or leaking, contact us with your order number and a photo and we will put it right. We cover the practical side of authenticity and returns in a later section.

The RTB Liq flavour range: 19 flavours in six families

Nineteen flavours is a generous list for a single-price range, and it helps to think of them in families rather than scanning a long menu. The descriptions below are based on the flavour names and on how similar profiles usually behave in nic salts. Flavour is subjective, and a name on a label is only a guide, so treat these notes as a starting point.

Ice and cooling fruit. Banana Ice, Pineapple Ice, Watermelon Ice, Cola Ice and VTM Ice make up the largest group. The Ice tag normally means a cooling agent has been added, so the flavour arrives with a cold finish rather than a plain fruit taste. VTM Ice is an abbreviated name that many vapers read as a mixed dark fruit blend in the style of a well-known soft drink. The label does not spell out the recipe, so consider that description a guide rather than a guarantee. If you have never tried a cooling flavour, Watermelon Ice and Pineapple Ice are straightforward places to begin because the fruit is easy to recognise.

Berry flavours. Blueberry Raspberries, Blueberry Sour Raspberry and Mr Blue form the berry group. The first is a sweet berry mix. The second adds a sour edge, which suits adults who find straight berry flavours too sugary. Mr Blue sits in the sweet, blue-flavoured candy territory that many adults know from other ranges.

Strawberry blends. Strawberry Banana, Strawberry Kiwi and Strawberry Brust (spelled this way in the product listing) pair strawberry with a second fruit. Strawberry Banana is the creamier, softer option. Strawberry Kiwi is sharper and brighter. Strawberry Brust, as the name suggests, is intended as a burst of strawberry sweetness.

Tropical and orchard fruit. Triple Mango, Kiwi Passion Fruit Guava, Juicy Peach and Double Apple cover the rounder, juicier end of the list. Triple Mango and Kiwi Passion Fruit Guava are the most intense of the group, with layered tropical notes. Juicy Peach is a gentler stone fruit profile, and Double Apple is the classic apple style that has been a staple of UK vape shelves for years.

Sweet and soda styles. Fruit Gum and Pink Lemonade are the dessert-adjacent options. Fruit Gum leans towards chewy fruit sweets, while Pink Lemonade combines a tart lemon note with a sweeter berry background. Cola Ice, mentioned above, belongs here too if you want a fizzy-drink profile with a cold finish.

Citrus and menthol. Lemon & Lime and Menthol are the sharper, cleaner options. Lemon & Lime is a zesty citrus pair that many adults describe as refreshing. Menthol is the only non-fruit flavour in the collection, and at the time of writing there are no tobacco flavours in this range. If you want a tobacco profile, our wider nic salts range has several.

A practical tip is to avoid buying ten bottles of a flavour you have never tried. Most adults switching devices find that they get bored of one flavour quickly. If you are unsure, pick a flavour from a family you already enjoy, and consider buying a second box in a different family later. Because the price is the same across the whole list, there is no cost penalty for trying something different next time.

Who RTB Liq suits, and who should look elsewhere

RTB Liq is for adults who already use nicotine and want a low-cost way to keep a refillable pod kit running. It is not for anyone under 18, and it is not for people who do not currently smoke or vape. If you have never used nicotine, there is no reason to start.

The people who tend to get the most from this kind of range look like this:

• Adults switching from smoking. A moderate strength such as 10mg is a common starting point for people who smoke around ten cigarettes a day or fewer, or who find 20mg too much. Heavier smokers often start at 20mg, so check your own habits before you decide.
• Former disposable users. Since the single-use ban, a reusable pod kit and a box of nic salt is the obvious replacement. The draw is similar, and the cost per day is usually lower once you have the kit.
• Budget-minded vapers. At roughly £1.30 per bottle, a box is a reasonable way to avoid paying single-bottle prices every week.
• People who like to change flavours. A single-price list of 19 flavours makes it simple to rotate without worrying about price differences.
• Adults who want a discreet, compact setup. Small pod kits plus 10ml bottles are easy to carry and low on vapour.

New vapers should think about whether 10mg is the right place to start. If you are coming off a pack-a-day habit, 10mg may feel light, and you may find yourself taking many more puffs than you intended. If you smoked only occasionally, 10mg may be strong enough already. There is no single right answer, and it is normal to try one box and then adjust.

Experienced vapers, particularly those who use sub-ohm tanks, will probably find that a 10mg salt is not what they want. Salts are designed for low-power draws, and a moderate-strength salt in a high-wattage tank will taste harsh and run through quickly. If your current setup is a sub-ohm tank on a mod, look at freebase liquids in our wider e-liquid range instead.

One more group to consider: adults who want stronger nicotine than 10mg. At the time of writing, this collection lists only 10mg. If you need 20mg, browse other nic salt brands in the store, all of which stay within the UK cap.

Strength, puffs and how long a box of RTB Liq lasts

E-liquid does not have a puff count the way a disposable did. A disposable vape was sold as, say, 600 puffs, because the manufacturer fixed the amount of liquid and battery inside it. A bottle of nic salt is simply a volume of liquid, and the number of puffs you get depends on the device, the coil, the power setting and the way you vape. Still, it helps to translate the bottle size into something you can picture.

A typical refillable pod holds up to 2ml, which is the maximum tank size allowed in the UK. A 10ml bottle therefore fills a pod about five times, and a box of ten bottles gives you around fifty fills. If you use the same rough convention that old 600-puff disposables used, with about 2ml per 600 puffs, a single bottle would stretch to something in the region of 3,000 puffs and a full box to around 30,000. Treat those numbers as a very loose guide, because real-world use varies widely. Some people finish a pod fill in half a day, and some stretch one over two or three days.

A simple way to estimate your own cost looks like this:

• Light use: about 1ml a day means a box lasts roughly 100 days.
• Moderate use: about 2ml a day, which is one full pod fill, means a box lasts roughly 50 days.
• Heavy use: about 4ml a day means a box lasts roughly 25 days.

At a moderate 2ml a day, the liquid costs about 26p a day, before you count coils or pods. That is a rough figure, but it gives you a starting point for comparing with other formats.

On strength, 10mg means 10 milligrams of nicotine per millilitre of liquid, which is 1 percent. UK law caps nicotine-containing e-liquid at 20mg, so 10mg sits at half the legal maximum. Because nic salts deliver nicotine efficiently, many users find that 10mg feels stronger than 10mg freebase would. If you find a strength too sharp or uncomfortable, take fewer and shorter puffs, and consider moving to a lower strength rather than pushing through. If you find yourself vaping almost constantly and still not feeling satisfied, a higher strength might suit you better, and you can move up to 20mg in another brand.

Flavour intensity also influences how much you vape. Strongly flavoured liquids, especially sweet or cooling ones, can encourage frequent puffing because the taste is pleasant. If you notice that you are vaping more than you planned, a plain Menthol or a lighter fruit such as Juicy Peach can be easier to moderate.

Devices and pod compatibility for RTB Liq

RTB Liq is a general-purpose nic salt in 10ml bottles. It is not locked to a single device in the way that a prefilled pod is, and it should work in any refillable pod kit or low-power refillable tank designed for nic salts. What matters is that the device is intended for mouth-to-lung vaping, uses a coil with a resistance of around 0.8 to 1.2 ohms, and runs at a modest wattage. Most compact refillable pod kits meet that description.

When you are deciding whether a particular kit will work, check these points:

• Refill method. The kit should have a fill port or removable pod that you can top up from a 10ml bottle. Many have a silicone bung or a side-fill slot.
• Coil resistance. Coils of around 0.8 to 1.2 ohms suit nic salts well. Very low resistance sub-ohm coils are designed for freebase liquid and bigger clouds.
• Power range. Nic salts do best at the low wattages that small pod kits use. If your device offers adjustable power, start low and work upwards slowly.
• Pod capacity. UK-sold kits are limited to 2ml tanks, so expect to refill regularly.
• Nozzle on the bottle. A thin nozzle helps when filling small ports. Check that your pod port accepts it.

A few things to avoid. Do not pour nic salt into a prefilled disposable pod unless the manufacturer specifically says it can be refilled, because those pods are often not designed for it and may leak. Do not use a high-power sub-ohm tank with a salt, because the flavour will be harsh and you will burn through liquid quickly. And do not mix freebase and salt in the same tank without cleaning it out, because the resulting flavour and strength can be unpredictable.

If you have just bought a new kit, prime the coil before you vape. Fill the pod, leave it for five to ten minutes so the cotton soaks fully, and take a few gentle draws without pressing the button. This reduces the chance of a dry hit, which tastes burnt and wears out the coil quickly. When you change flavours, empty the pod, rinse it according to the manufacturer guidance, let it dry, and refill. Coils that have been used for a strong menthol or cooling flavour often hold a trace of that taste for a while, so you may prefer to fit a fresh coil before switching to a sweet fruit.

If you are not sure whether your device suits nic salts, check the instruction leaflet or the manufacturer website, or ask us before ordering.

How RTB Liq compares with other nic salt formats and brands

Comparing RTB Liq with other options is easiest if you separate the format from the brand. The format question is whether you want a bottle of salt for a refillable kit or a ready-made pod. The brand question is how this range stacks up against other bottled nic salts that we sell.

On format, a bottle of nic salt differs from a prefilled pod in several ways:

• Cost per millilitre. Bottled salts generally cost less per millilitre than prefilled pods, because you are not paying for the pod hardware each time.
• Flexibility. With a bottle you can change flavour whenever you like. With prefilled pods you are limited to the flavours the device maker sells.
• Convenience. Prefilled pods click in and are ready to use. Bottles need filling, and fills can be fiddly for newcomers.
• Waste. A bottle creates a small amount of plastic waste per fill. A prefilled pod creates a pod and a coil each time, which is more to recycle.

On brands, the nic salt multipack market in the UK is busy. Ranges from Elf Liq, IVG, Hayati, Bar Juice, Titan, Kingston and others are sold in boxes of five or ten 10ml bottles, usually at 10mg or 20mg, and often with many flavours each. Compared with those, RTB Liq's position is that of a straightforward, single-price value pack. It is not trying to be a dessert-focused premium line or a collaboration with a device maker. The flavour list is broad but conventional, the price is flat, and the strength is moderate.

Where RTB Liq may differ from other brands is in the detail. Some competitors sell the same flavour in 5mg, 10mg and 20mg boxes, which lets you tune your strength without changing brand. Others publish flavour descriptions, PG and VG ratios and ingredient details on their own websites, which helps if you are particular about what goes in your kit. With RTB Liq, the most reliable source for ratios and ingredients is the label on the bottle, and you should read it once the box arrives.

As a rough guide to value, a ten-bottle box at £12.99 sits towards the lower end of what ten-bottle nic salt boxes cost in our catalogue, where most land somewhere between the mid teens and around twenty pounds. Boxes of five bottles can carry a similar headline price, which makes the per-bottle cost of RTB Liq comparatively low. Always compare the per-bottle cost, the strength and the bottle count, not just the headline price, because a box of five at a similar price is not the same deal as a box of ten.

If you want stronger nicotine than 10mg, a wider flavour list with dessert and drink profiles, or a brand that offers the same flavours at several strengths, other nic salt ranges in the store may suit you better. If you want a low-cost, no-fuss multipack in recognisable fruit and ice flavours, RTB Liq is worth considering.

UK law, buying genuine stock, warranty and returns

Vaping products in the UK are governed by the Tobacco and Related Products Regulations 2016, often shortened to TPD. For a bottle of nic salt like RTB Liq, the main rules are as follows:

• Maximum nicotine strength of 20mg per millilitre. This applies to all nicotine e-liquid and, until their ban, applied to disposable vapes too. RTB Liq at 10mg is well inside the limit.
• Maximum bottle size of 10ml for nicotine-containing e-liquid. Larger bottles are only legal for nicotine-free liquid.
• Maximum tank or pod size of 2ml. This is why refills are frequent.
• Child-resistant and tamper-evident packaging, with health warnings and ingredient information on the label.
• Age restriction of 18. It is illegal to sell nicotine vaping products to anyone under 18, and it is also illegal for an adult to buy them on behalf of someone under 18.

Disposable vapes are a separate matter. Single-use vapes were banned in Great Britain on 1 June 2025, so you cannot buy a new disposable from a UK retailer. The 20mg cap that applied to them still applies to every nicotine e-liquid and refillable kit, which is why nic salt bottles top out at 20mg.

Authenticity matters because counterfeit and grey-market vape products are a real problem in the UK. Here is how to protect yourself:

• Buy from a retailer that states age verification and UK sourcing. Stock sold here is genuine and shipped from the UK.
• Check the packaging. A genuine box should be sealed and printed cleanly, with the brand name, flavour, strength and bottle count. Blurry printing, spelling errors or missing information are warning signs.
• Read the bottle label. It should carry the required UK health warning, the nicotine strength, the volume, the ingredients and a batch or lot reference.
• Look at the seals. Each bottle should have a tamper-evident ring on the cap and a child-resistant closure.
• Be suspicious of very low prices. If a box of ten is priced far below the typical range, ask why.

On warranty and returns: e-liquid does not carry a hardware warranty because there is nothing mechanical to fail. If an item arrives damaged, leaking or not as ordered, tell us promptly with your order number and photos, and we will deal with it. For opened or used bottles, the rules are different for hygiene reasons, so check our returns page for the full policy.

On delivery, UK orders over £20 ship free. A single box of RTB Liq at £12.99 falls under that threshold, so adding a second box or a coil pack brings you over it. Orders placed before 4pm are dispatched the next day.

Honest value guidance, care, storage and recycling

The honest value case for RTB Liq is simple. At £12.99 for ten bottles, the liquid costs about 13p per millilitre. For someone using one pod fill a day, that is roughly 26p of liquid per day. Your total running cost will be higher once you add coils or pods, which typically cost a few pounds each and last from one to three weeks depending on flavour and use. Sweet liquids tend to wear coils faster than clear or fruity ones, because sugars build up on the cotton. Cooling flavours do not usually add much wear, but they can leave a lingering taste.

There are some trade-offs to be honest about. A moderate-strength multipack in one strength does not give you flexibility if your needs change. A single-price list suggests the flavours were chosen for popularity, not for subtlety, so adults who prefer delicate or complex blends may find some of the fruit-and-ice profiles too uniform. And a bottle format requires you to fill and maintain a kit, which some people find a chore compared with clicking in a prefilled pod.

Care and storage for your bottles are straightforward:

• Keep them out of reach of children and pets. Nicotine liquid can be harmful if swallowed or if it gets on skin. Store bottles upright in a cupboard, not on a table.
• Avoid heat and sunlight. A cool, dark place keeps flavour and colour stable. Do not leave bottles in a hot car.
• Keep caps closed. This prevents spills and slows oxidation. If a liquid darkens over time, that is normal for some flavours, but a strong change in smell or taste is a sign it should be replaced.
• Wipe filling nozzles. A clean nozzle helps avoid sticky residue and cross-contamination between flavours.
• Rotate stock. If you buy several boxes, use the oldest first and check the date on the bottle label.

For your kit, wipe the mouthpiece and the pod contacts regularly with a dry cloth or cotton bud. Replace the coil when the flavour fades, when the vapour becomes weak, or when you notice a burnt taste. Never fill above the maximum line, and never overfill the air channel, as this causes leaks and gurgling.

Recycling matters too. Empty bottles are small plastic items, and whether they can go in household recycling depends on your local council, so check its guidance before you decide. Vape kits, batteries and pods should never go in general waste or household recycling because lithium batteries can start fires. Shops that sell vapes are required to accept old vapes and batteries for recycling, and many councils run drop-off points at household waste recycling centres and some supermarkets. If you are unsure where your nearest drop-off point is, ask in-store or search your council website for vape and battery recycling.

Used responsibly and stored sensibly, a box of RTB Liq is a low-cost way to keep a pod kit going for several weeks. Check the strength, pick a flavour you already like, and remember that the product is for adults only.
