Oxva Ox Passion Nic Salt E-Liquid Rinbo at a glance

Oxva Ox Passion Nic Salt E-Liquid in the Rinbo flavour is a 10ml bottle of nicotine salt e-liquid for vapers who want a sweet, fruity, candy-leaning flavour in a pod kit or another low-power device. Oxva is a name UK vapers know mainly for hardware, in particular the Xlim and NeXlim families of pod systems, so a liquid sold under the Oxva banner is naturally built around the compact, low-wattage devices those kits represent. Nic salt formulations suit that setup because they deliver nicotine smoothly at modest power, with a tight, cigarette-like draw instead of a big cloud.

This page is written for UK buyers and takes a practical view. It covers what Rinbo is likely to taste like, how it behaves in different devices, which nicotine strength makes sense, how far a bottle goes, and where it sits against comparable nic salts and against the disposables many people are leaving behind. Where we cannot confirm an exact figure, such as the precise VG/PG split of the batch in your hands, we say so and point you to the bottle label rather than guessing.

• Type: nicotine salt e-liquid in a 10ml bottle, which is the largest size UK rules allow for liquid containing nicotine
• Flavour: Rinbo, a rainbow-style mixed fruit candy profile
• Strengths: nic salt liquids are normally sold at 10mg/ml and 20mg/ml, with 20mg/ml being the UK ceiling; pick from the options on the product page
• Typical base: a balanced VG/PG mix, commonly close to 50/50 for nic salts, so always check the label on your bottle
• Suited to: refillable pod kits and pod-style devices with coils in roughly the 0.4 to 1.2 ohm range
• Age restriction: 18+ only, with age checks at order

If you have been buying Oxva hardware and want a liquid from the same brand family to go in it, Rinbo is one of the straightforward fruit options in the range. If you are new to nic salts, the sections below explain the basics before you spend anything.

Flavour profile: what Rinbo is likely to taste like

Flavour is the hardest thing to judge from a name alone, and Rinbo is a short, stylised word rather than a plain fruit. Read as a spelling of rainbow, it points to the mixed fruit candy family: a sweet blend of several fruit notes rather than one single fruit. We would rather describe the category honestly than invent a tasting note the bottle does not promise, so treat what follows as a guide to the style, not a laboratory breakdown.

Rainbow-style candy liquids tend to share a few traits. The inhale is usually bright and sweet, with a layered fruit character that reads as strawberry, citrus, apple or berry sweets depending on how your palate interprets it. The exhale tends to be rounder and more sugary, closer to a boiled sweet or a fruit chew than to fresh fruit. There is generally no menthol or cooling agent in a profile like this, so the finish stays warm and sweet instead of icy.

• Sweetness: medium to high. Candy profiles lean on sweeteners, which is part of their appeal and also why they can feel heavy over a long session.
• Acidity: usually a light sharp edge to stop the sweetness becoming flat, similar to sour sweets but far gentler.
• Body: a smooth mid-weight vapour rather than a thin, watery one, helped by the nic salt base.
• Cooling: none expected, so it suits anyone who finds menthol overpowering.

A useful way to decide is to think about what you already enjoy. If you like mixed fruit chews, fizzy-free fruit sweets or the flavours common in popular disposables, Rinbo sits in your territory. If you prefer dessert, tobacco or crisp menthol flavours, a candy profile will probably feel too sweet and you would be better served elsewhere in the Ox Passion line, which runs across many fruit, ice and candy options.

One practical note on palate fatigue: very sweet liquids can start to taste muted after several days of constant use. Keeping a second, different flavour to rotate with often brings the sweetness back, and it costs little when bottles are priced like these.

Performance and throat hit in everyday use

The performance of any e-liquid depends on three things working together: the liquid itself, the device it goes in, and the way you draw on it. Rinbo is a nic salt, so its character is set by the salt nicotine and the VG/PG balance, and in the right device it behaves in a very predictable way.

Nic salt liquids use a different form of nicotine from freebase liquids, combined with an acid so that the nicotine is easier on the throat. The result is a gentler throat hit at any given strength, which is why salts are the default choice in pod devices and in most UK disposables. At 10mg/ml the hit is light and easy to live with. At 20mg/ml the hit is firmer and the nicotine arrives quickly, which is what many people stepping down from cigarettes are looking for.

• Throat hit: smooth for the strength. The candy flavour helps by rounding off the edge, so even the 20mg/ml option should feel softer than the same strength in a freebase.
• Vapour production: modest. Nic salts are designed for low power, so expect a compact cloud rather than a plume. This is normal, not a fault.
• Flavour delivery: best at the low end of your device's power range. Pushing a salt hard tends to flatten the sweetness and add a harsh note.
• Nicotine delivery: fast and efficient. Salts reach the bloodstream in a pattern closer to a cigarette than freebase does, which is why people often vape less often in terms of puffs.

The draw you use matters more than most people expect. Rinbo is intended for a mouth-to-lung draw: pull gently into your mouth for a couple of seconds, pause, then inhale. A slow, steady draw gives a fuller flavour and keeps the nicotine comfortable. A fast, hard pull on a tight pod can taste thin and feel sharper on the throat.

As with any salt, performance is consistent from the first fill to the last as long as the coil is healthy. If the flavour starts to fade well before the bottle is empty, the coil is usually the reason rather than the liquid, and we cover that in the troubleshooting section.

Choosing your nicotine strength: 10mg or 20mg

Choosing the right strength is the single decision that affects whether you enjoy this liquid. Nicotine strength is expressed in milligrams per millilitre, so 10mg/ml is 1 percent and 20mg/ml is 2 percent. UK rules cap refillable e-liquid and prefilled pods, including disposables, at 20mg/ml, which is why you will never see a UK-sold liquid above that number.

This is general product guidance and not medical advice. Everyone absorbs nicotine differently, and the numbers below are starting points you should adjust to how you feel.

• 10mg/ml: a sensible starting point if you smoked fewer than around ten cigarettes a day, if you are already on a lower strength, or if you vape throughout the day and want to avoid overshooting. It is also the better choice if you find 20mg/ml harsh or lightheaded.
• 20mg/ml: the usual choice for people who smoked a pack a day or close to it, who want to feel satisfied with a small number of puffs, or who are moving away from 20mg disposables and want the same strength in a refillable form.

Signs you have picked too high: dizziness, nausea, a harsh scratch in the throat, a racing pulse or a headache after a few puffs. Signs you have picked too low: you find yourself chain-vaping, craving cigarettes soon after finishing a session, or taking long draws without feeling settled. If you see the first set, drop a strength or pair a lower strength with a lower-power device. If you see the second, move up carefully.

Remember that strength and device interact. A 20mg/ml salt in a low-power pod behaves well. The same liquid pushed through a high-wattage device produces far more vapour per puff, which means far more nicotine per puff and a rough throat hit. Salts are not intended for high-power sub-ohm use, so if you run a mod at 40W or above, a freebase liquid in a lower strength is the better fit.

If you are not sure, buy the lower strength first. Moving up is easy; getting used to a strength that was too high is unpleasant. People using vaping to quit smoking should also consider speaking to a local stop smoking service, which can offer free support in many parts of the UK.

Bottle design and build quality

The container matters more than people think, because a poor bottle means spilled liquid, a contaminated tip and a dirty pocket. Ox Passion nic salts are supplied in the 10ml plastic dropper bottle format that UK law has made standard for nicotine liquid. The pack is built around the legal requirements, so you can expect the features below on a genuine bottle.

• Child-resistant cap: the cap needs a push-and-turn to open. It can feel fiddly the first time, and that is by design.
• Tamper-evident seal: a ring or band that breaks on first opening. If it is already broken when you receive the bottle, contact us rather than using it.
• Narrow nozzle: a thin tip sized to fit the fill port on most pod devices without spilling. Check the tip against your pod fill hole before your first fill.
• Soft, squeezable plastic: lets you control the flow. Squeeze gently, because salts are usually more fluid than thick freebase liquids and will come out faster than you expect.
• Printed label: carries the strength, volume, ingredients list, batch number, health warning and contact details. Keep the batch number if you ever need to report a problem.

Plastic bottles flex over time, and leaving a bottle in a warm pocket or a hot car encourages leaks around the cap. Store it upright, tightly closed, away from heat and out of direct sunlight. A bottle left lying on its side in a bag is the most common cause of a leak in transit.

On the build quality of the liquid itself, the sensible expectation is a consistent, clear liquid with an even colour and no cloudiness, sediment or odd smell. Many candy flavours carry a slight tint from the flavouring. A tint is normal. Floating particles, a separated layer or a chemical smell are not, and the liquid should not be used.

Keep every bottle, filled or empty, out of reach of children and pets. Nicotine is toxic if swallowed or if it gets on skin in quantity, and any spill on skin should be washed off promptly with water.

Matching Rinbo to coils and mesh

Because Rinbo is a nic salt, the coil in your device decides most of what you taste. A bottle of e-liquid cannot compensate for a tired or mismatched coil, so it is worth understanding how coils and mesh work before you fill anything.

Pod devices from Oxva and other makers generally use one of two coil styles. Traditional wire coils sit inside a cotton wick and heat it from a spiral of wire. Mesh coils use a flat or curved sheet of fine metal mesh pressed against the wick, which spreads the heat across a much bigger surface. Mesh typically warms up faster, heats more evenly and gives a fuller flavour at a given power, which suits sweet candy profiles that rely on a rounded finish.

• Around 0.8 to 1.2 ohm: tighter, cigarette-like draw. This range suits 20mg/ml salts, because the lower airflow limits how much vapour and nicotine each puff delivers.
• Around 0.6 ohm: a middle ground with a slightly airier draw. Works well with either strength.
• Around 0.4 ohm or lower: a looser, more open draw with more vapour. Better paired with the 10mg/ml option, since you will take in more liquid per puff.

Salts at roughly 50/50 VG/PG wick quickly, which is exactly what small pod coils want. Very thick liquids can starve a coil and cause burnt tastes, and very thin ones can leak. A balanced nic salt like Rinbo avoids both problems on most kits.

Check what your device's maker recommends. Some pod systems list a wattage range for each coil, and staying within it gives the cleanest flavour. If your pod has adjustable power, start at the low end of the range for the coil you are using and nudge up only if the flavour feels thin.

Coil life is the other half of the story. With sweet candy liquids, residue builds up on the coil faster than with unsweetened or tobacco flavours, so expect a coil to last somewhere around a week or two of regular use rather than a month. When the flavour turns flat, muddy or slightly burnt, fit a fresh coil before blaming the bottle. If you want to extend coil life, avoid chain-vaping and give the liquid a few seconds to re-saturate the wick between draws.

Battery and charging: looking after the device it goes in

An e-liquid has no battery of its own, but the device you pair it with does, and good battery habits make a visible difference to how Rinbo tastes and how long the kit lasts. Pod devices commonly use built-in batteries somewhere between roughly 400mAh and 1,000mAh, and charge over USB-C. A larger battery supports more puffs between charges, while a smaller one suits a slim pocket device. Check your specific kit for its exact figure, as it varies between models.

A low battery does not just mean the device stops working. As voltage falls, a lot of pods deliver less power to the coil, and a salt like Rinbo can feel thin and under-flavoured in the last stretch of a charge. If you notice dull flavour and weak vapour that perks up after a recharge, battery level is probably the cause.

• Use the supplied cable or a reputable USB-C cable. Cheap, unbranded cables are a common reason for slow or inconsistent charging.
• Use a standard 5V phone charger or a computer USB port. Avoid fast-charge adapters that you cannot confirm are compatible.
• Do not charge unattended or overnight on a soft surface. Charge on a hard, clear surface and unplug when the indicator shows full.
• Keep the charging port dry and clear. E-liquid residue in the port can interrupt charging; wipe it out with a dry cotton bud.
• Avoid extreme heat and cold. Do not leave the device on a dashboard, radiator or in freezing conditions.

If the battery swells, becomes hot to the touch while idle, smells of chemicals or fails to hold charge, stop using it. Do not try to repair a built-in cell yourself.

When a device reaches the end of its life, it should not go in your household bin or kerbside recycling. In the UK, vapes and their batteries are electrical and battery waste. You can take them to a household waste recycling centre, to a retailer that offers in-store take-back, or to a battery drop-off point, many of which are found in larger supermarkets. Empty e-liquid bottles can usually go into plastic recycling once rinsed and the cap is removed, but check the rules in your local authority area, because they vary.

How to use Rinbo: filling, priming and first puffs

Filling a pod properly is the difference between a clean first puff and a dry, burnt one. The steps below apply to most refillable pod kits. Follow your device's own instructions where they differ.

• Check the coil and pod. Make sure the coil is seated firmly and the pod is not cracked. If the coil is new, remove any plastic wrap or protective film.
• Open the fill port. Most pods have a silicone bung or a small sliding cover. Lift or slide it clear.
• Fill slowly. Press the nozzle against the fill hole and squeeze in small amounts. Stop just below the maximum line, or about two-thirds to three-quarters full, to leave room for air.
• Close the port. Make sure the bung is fully pushed back in, or the pod will leak.
• Let it prime for 5 to 10 minutes. This is the step people skip. The cotton wick needs time to soak up liquid, and a dry wick burns on the first puffs and can ruin the coil.
• Take a few gentle draws without pressing hard. Short, soft puffs wake up the coil. Then vape as normal.

In the UK, refillable tanks and pods are limited to 2ml. That is a legal requirement and is the reason a 10ml bottle will fill a pod several times over. Keep the rest of the bottle closed and upright between fills.

Day-to-day habits make a difference:

• Top up before the pod is empty. Running a coil dry is the quickest way to shorten its life.
• Wipe the nozzle clean after filling so it does not collect dust and lint in your bag.
• If you change flavour, empty the pod and wipe it dry first, or you will taste a mix of the old and new liquid for the first few puffs.
• Do not mix salts with freebase liquids in the same pod. The result is unpredictable and not worth the saving.

For anyone new to vaping, the first few sessions with a candy flavour can feel sweeter than you expect. Take it slowly, start on the lower strength, and give your palate a day or two to adjust. Most people settle on a comfortable routine within a week.

How long a 10ml bottle lasts

Nobody can give you an exact number of puffs for a bottle of liquid, because it depends on your device, your coil, your power setting and how you draw. What we can offer is a reasoned estimate to help you plan, and we will be clear that it is an estimate.

As a rough planning figure, a pod device at modest power uses somewhere around 0.03 to 0.06ml of liquid per puff. That works out at roughly 150 to 300 puffs per millilitre, which makes a 10ml bottle worth somewhere in the region of 1,500 to 3,000 puffs. Light users will sit at the top of that range; heavy users or people running a coil at higher power will sit at the bottom.

• Light use (a few sessions a day): a bottle can last two to three weeks.
• Moderate use (steady vaping through the day): often around a week to ten days.
• Heavy use (frequent chain-vaping or higher power): three to five days.

To put that in context, a typical single-use vape in the UK carried 2ml of liquid at up to 20mg/ml, and was often marketed at around 600 puffs. A 10ml bottle holds five times that volume. In practice, one bottle is roughly the same liquid as five of those disposables, with the added benefit that you reuse the same device rather than throwing one away every few days.

Higher-strength salts also tend to be vaped less. At 20mg/ml many people find they satisfy their cravings in fewer, shorter sessions, which stretches a bottle further than the same volume at 10mg/ml. If you move to a lower strength, expect to take more puffs for the same effect and plan on the bottle going down faster.

You can stretch a bottle by keeping the coil healthy, using the lowest power that gives you good flavour, and keeping the pod clean. A coil that is choked with residue needs more power to get the same result, and it burns through liquid unevenly. Replace it on time and the liquid you do pay for goes further.

Who Rinbo is for, and who should look elsewhere

Good product pages should tell you when a product is not for you, so here is a straight view of who will probably enjoy this liquid and who may be better served by something else.

Rinbo is likely to suit:

• Adult smokers moving to vaping who want a nic salt at 20mg/ml or 10mg/ml in a pod kit, with a flavour that does not taste of tobacco.
• Former disposable users who now want a refillable setup after single-use vapes were banned from sale in the UK in June 2025. A nic salt candy fruit in a pod kit is the closest like-for-like replacement for the style many people were buying.
• Owners of Oxva pod devices who prefer to stay within one brand family for their hardware and liquid.
• Vapers who like sweet, layered fruit flavours and do not want menthol or an ice finish.
• People who value value-for-money, since a 10ml bottle costs far less per millilitre than a disposable.

You should probably look elsewhere if:

• You have never smoked or vaped. Nicotine is addictive and vaping is intended for adults who already use nicotine. If you do not currently use nicotine, you should not start.
• You are under 18. It is illegal to sell nicotine products to under-18s in the UK, and we age-check orders.
• You dislike very sweet flavours. Choose a tobacco, mint or unsweetened profile instead.
• You run a high-powered sub-ohm mod. Salts are not designed for that, and a freebase 50/50 or 70/30 liquid will suit you better.
• You are pregnant, have a heart condition or are taking medication that interacts with nicotine. Speak to a doctor or pharmacist before using any nicotine product.

If you are undecided between strengths or flavours, think about the situation in which you will use it. A short break at work suits a stronger salt in a small pod. A relaxed evening session suits a lower strength you can keep going without overdoing it.

Troubleshooting common problems

Most problems with nic salts are small and easy to fix. Work through the likely cause before assuming the bottle is faulty.

• Weak or fading flavour. Most often a tired coil, especially with sweet liquids. Fit a new coil. Also check you are not vaping on a low battery, and consider whether palate fatigue is the cause by switching flavours for a day.
• Burnt or dry taste. The wick is not saturated. Refill the pod, prime for several minutes and take gentle draws. If the burnt taste continues after a fresh fill and prime, the coil is damaged and needs replacing.
• Gurgling or spitting. Excess liquid in the airway, often from overfilling or from condensation. Tilt the pod, blow gently through the mouthpiece to clear it, and fill to a lower level next time.
• Leaking from the pod. Check the bung is fully closed, the pod is seated correctly and the coil is not cracked. Overfilling and warm pockets are the usual culprits.
• Harsh throat hit. The strength may be too high, the power may be too high, or you may be drawing too hard. Try a lower strength or a slower, gentler draw.
• Dizziness or nausea. This points to too much nicotine. Stop, drink some water, and move to a lower strength or take fewer puffs.
• Weak vapour with a charged battery. Check the airflow is not blocked by lint or liquid, and wipe the contacts between the pod and the battery with a dry cloth.
• Sticky residue on the outside of the device. Wipe it off with a slightly damp cloth, then dry. Residue near the contacts or charging port can stop the device working properly.

If you have tried these steps and the liquid still tastes wrong, smells unusual or looks cloudy or separated, stop using it. Keep the bottle and its batch number, and contact us with photos. We will look at what happened and tell you what we can do.

For any suspected faults with a device, always follow the manufacturer's guidance and use only compatible parts. Never open or modify a battery.

Value for money, comparisons and UK rules

On price per millilitre, a 10ml nic salt bottle is one of the cheaper ways to vape. The Ox Passion line has been listed at low single-figure prices per bottle, and multibuy offers have applied across qualifying flavours, so check the product page for the current price and any live deal. The cost of a bottle works out at only a fraction of what the same volume of liquid costs inside a disposable device, and you are not paying for a battery and plastic casing that goes in the bin after a few days.

Here is how Rinbo compares in fairness against the main alternatives:

• Against other nic salt brands such as those sold under Elf Bar, Lost Mary and similar names: the formats are alike, with 10ml bottles at 10mg/ml and 20mg/ml. The choice usually comes down to flavour preference and price. Some of those lines are better known and have wider flavour ranges; Ox Passion's selling point is brand consistency for Oxva hardware owners.
• Against disposables: a disposable is convenient but costs more per millilitre, creates more waste and, since the June 2025 ban on single-use vapes, is no longer something UK retailers can sell. Refillable pods and bottled salts are the legal route for the same style of vaping.
• Against freebase liquids: freebase suits higher-power devices and gives more vapour, but at the same strength it is harsher on the throat. For pod kits, salts are the better match.
• Against shortfills: these come in bigger bottles with no nicotine and are for sub-ohm devices, so they are a different product for a different device.

Where Rinbo is weaker: it is a sweet candy flavour, so it can tire the palate, and it is a salt, so it is not for high-power kit. Where it is stronger: it is straightforward, inexpensive, and works in the pod devices most people already own.

On UK rules, nicotine e-liquid is capped at 20mg/ml and sold in bottles of no more than 10ml. Refillable tanks and pods hold no more than 2ml. Bottles carry child-resistant caps and health warnings, and products are notified to the regulator before sale. All sales are limited to adults aged 18 and over.

Finally, recycle responsibly. Rinsed empty bottles can usually go into plastic recycling with the cap off, and devices and batteries belong at a household waste recycling centre, a retailer take-back scheme or a battery drop-off point, not in a general bin.
