Zeus Bolt Nic Salts Banana Custard 10ml 20mg at a glance

Zeus Bolt Nic Salts Banana Custard is a 10ml bottle of nicotine salt e-liquid in a 20mg/ml strength, sold for refillable pod kits and other low-power devices. The flavour is a dessert profile: ripe banana layered over a smooth, vanilla-leaning custard. It is made for vapers who want a creamy, sweet liquid that suits a gentle, mouth-to-lung draw rather than a big cloud-chasing setup.

Here is what the listing tells us, and what it does not. The name confirms the brand (Zeus), the range (Bolt), the format (nic salts), the volume (10ml), the nicotine strength (20mg/ml) and the flavour (banana custard). Anything beyond that, such as the exact VG/PG split, the ingredient list and the batch code, is printed on the bottle label and the carton, and that label is the authority. We would rather point you to it than guess a number and have you rely on it.

• Brand and range: Zeus, Bolt nic salts
• Bottle size: 10ml, the largest size UK rules allow for nicotine e-liquid
• Nicotine strength: 20mg/ml (2%), the maximum strength permitted in the UK
• Nicotine type: nicotine salt, which is smoother at higher strengths than freebase nicotine
• Flavour: banana custard, a sweet dessert profile
• Best suited to: pod kits and low-wattage refillable devices

A 10ml bottle of 20mg nic salt is the standard format for UK vapers who have moved on from disposables or who are leaving cigarettes behind. Since the sale of single-use vapes was banned in the UK on 1 June 2025, refillable kits and bottled salts have become the normal route for anyone who wants a ready-to-use, nicotine-strength liquid without buying a throwaway device every few days.

The rest of this page walks through how the liquid is likely to perform, what the flavour tastes like, what devices suit it, how to choose between strengths, how to fill and look after your kit, what to do if something goes wrong, and how it compares with other options at a similar price. Where we are estimating rather than quoting a manufacturer figure, we say so.

One point of housekeeping before we go further. This product contains nicotine, which is addictive. It is for adults aged 18 or over only, and it is intended for people who already smoke or vape. If you do not use nicotine today, this is not a product to start with.

Flavour profile: what banana custard tastes like

Banana custard is one of the more recognisable dessert flavours in vaping, and most versions follow the same blueprint: a soft, slightly candied banana note on the inhale and a vanilla-and-cream custard body that lingers on the exhale. The banana in vape flavouring tends to taste closer to a ripe banana sweet or a banana milkshake than to a fresh, slightly tart fruit, and that is the direction to expect here.

We have not been given a tasting note from Zeus, so treat the following as a description of the flavour style rather than a guarantee of this exact recipe. The structure usually looks like this:

• On the inhale: a sweet, rounded banana with a gentle fruit-sweet edge, often with a hint of vanilla starting to build.
• Mid-draw: a creamy body where the custard takes over, usually smooth rather than eggy.
• On the exhale: a lingering vanilla-cream finish with a soft banana aftertaste that fades over a few seconds.

Nic salts tend to carry flavour clearly at the lower power levels pod devices use, because the cooler vapour is less likely to scorch delicate cream and vanilla notes. A hotter, high-wattage setup can flatten a custard flavour or push it towards a toasted, slightly burnt taste, which is one reason this kind of liquid pairs better with pods and small coils than with sub-ohm tanks.

Sweetness is the thing to be aware of. Dessert liquids use sweeteners and creamy flavour concentrates, and those residues can build up on a coil faster than the lighter ingredients in a menthol or a fresh fruit liquid. If you vape banana custard all day, you will likely replace pods or coils a little sooner than you would with an ice or tobacco flavour. That is a normal trade-off with the whole dessert category rather than a flaw in this particular bottle.

Compared with a fruit-and-ice flavour, banana custard is mellow. There is no cooling agent masking the throat, so the nicotine is not buffered by menthol, and the flavour is more filling and less refreshing. Many vapers like it as an evening or after-meal flavour, and many find that it is easier to stay off cigarettes with a satisfying dessert profile than with a sharp, short-lived one.

If you are not sure whether you will like it, try a small quantity first. Banana is polarising: some people enjoy the candy-like sweetness, others find it artificial. Custard flavours also vary between brands from light and milky to thick and buttery, so the same name can taste quite different from one label to the next.

Performance and vapour delivery

Because this is an e-liquid rather than a device, performance depends on the kit you use it in. We cannot quote a puff count printed by the manufacturer for the liquid itself, but we can reason about it so you can plan how long a bottle lasts.

As a working estimate, a 10ml bottle of nic salt gives somewhere around 1,500 to 3,000 puffs in a typical pod kit, depending on draw length, device wattage and how much liquid your coil vaporises per puff. The spread is wide for good reasons. A short, light draw on a 10 to 12 watt pod uses far less liquid than a long, hard draw on a 20 watt device. Treat the range as a planning figure, not a promise.

• Light user (a few dozen puffs a day): a bottle can last several weeks.
• Moderate user (a few hundred puffs a day): expect roughly one to two weeks per bottle.
• Heavy user (all-day vaping at 20mg): a bottle may last under a week, and you may want to consider whether a lower strength would serve you better.

Throat hit. Nic salts at 20mg/ml deliver nicotine more smoothly than freebase liquids at the same strength. The throat hit is present but softer, which is why salts are popular with people stepping off cigarettes. At 20mg you should still expect a noticeable hit, so draw gently at first.

Nicotine delivery. Nicotine salts are formulated to absorb faster than freebase nicotine and to feel gentler while doing so. For a smoker used to getting a quick satisfying dose, that is the main appeal. It is also why 20mg salts can feel strong to a newer vaper, so respect the strength.

Vapour production. Expect modest clouds. Nic salt liquids are typically used in low-power devices that produce discreet, cool vapour with a short dissipation time. If you want large clouds, a high-VG shortfill with a sub-ohm tank is the right category, and a 20mg salt in a high-power device would be harsh and wasteful.

Consistency from first puff to last. With a pod or coil that is correctly primed and not flooded, the flavour should stay steady until the coil begins to age. If the taste drops early, that points to a worn coil or a low liquid level, not a problem with the liquid itself. We cover the fixes in the troubleshooting section below.

Bottle design and build quality

The product is a 10ml plastic dropper-style bottle, which is the format UK rules require for nicotine-containing e-liquid. Bottles in this category are normally made of soft, squeezable plastic with a narrow nozzle for filling small pod ports, and a tamper-evident, child-resistant cap. That is the format to expect here, and you should confirm the details on the bottle you receive.

UK rules shape the bottle more than any brand does. Nicotine e-liquid for refilling must be sold in containers of no more than 10ml, with a child-resistant and tamper-evident closure, a nicotine warning and a leaflet or label with usage and ingredient information. The practical effect is that every compliant bottle looks broadly alike in size and function, and the differences come down to nozzle quality, how well the label survives handling and how cleanly the cap seals.

• Nozzle: a narrow, long tip is useful for small pod fill holes and reduces spills.
• Cap: child-resistant caps are fiddly by design. Press down and turn as directed on the cap.
• Label: should list nicotine strength, volume, ingredients, batch number, best-before date and warnings. Check these on arrival.
• Seal: an intact tamper-evident ring on arrival confirms the bottle has not been opened.

Storing the bottle properly matters more than it sounds. Light, heat and air degrade nicotine and flavour over time. Keep the bottle upright, capped, out of direct sunlight and away from radiators, and keep it out of the reach of children and pets. A cupboard or drawer at room temperature is ideal. Do not leave it in a hot car.

E-liquid darkens as it ages, and nicotine oxidises. A slightly deeper amber colour after a few months is normal and does not mean the liquid has gone off, but if it becomes very dark, smells off or tastes noticeably worse, replace it. Always check the best-before date on the label.

Disposal is worth a mention because it is where many people slip up. Empty plastic e-liquid bottles can go in household plastic recycling in many council areas, but check your local authority because some collections will not accept bottles that previously held nicotine. Any batteries, pods with batteries attached or kit parts should not go in general waste or household recycling. The next section explains where to take them.

Compatible devices, battery and charging

A bottle of liquid does not have a battery of its own, so battery performance depends on the device you pair it with. Nic salts are designed for low-power hardware, and in practice that means pod kits and small refillable vapes.

Typical hardware for 20mg nic salts includes slim pod systems with built-in batteries, usually in the range of 400mAh to 1,000mAh for compact pens, and larger pod mods at 1,000mAh to 1,500mAh and above. These figures describe the common market range, not a spec for any one device. If you already own a pod kit, check its documentation for its own battery capacity and its power range.

• Small pod pens (about 400 to 800mAh): light and discreet, usually good for a day of moderate use between charges.
• Mid-size pod kits (about 800 to 1,500mAh): comfortable for heavier use and often with adjustable airflow.
• Large pod mods (1,500mAh and over): longer runtime, sometimes with variable wattage. Keep the power low for salts.

Charging. Most modern kits charge by USB-C. A fully drained small pod typically takes around 30 to 60 minutes to refill, and larger batteries take longer. Use a quality charger and a standard USB port or a plug-in adapter of modest output. Avoid unknown cheap chargers, do not charge overnight on a soft surface such as a bed or sofa, and do not charge a swollen, hot or damaged device. If a kit is damaged or leaks, stop using it.

Power settings. If your device has adjustable wattage, nic salts generally taste best at lower power, often in the region of 8 to 15 watts for a pod with a coil of about 0.8 to 1.2 ohm. Start at the low end, then step up in small increments if the flavour feels thin. Going too high will make the vapour warm and harsh and use more liquid than needed.

UK recycling for batteries and devices. Never bin a vape or a battery in household waste. Lithium batteries can start fires in bin lorries and recycling plants. Under UK waste electrical rules, shops that sell vapes are required to take back old vapes and batteries, and you can usually drop them at a household waste recycling centre as well. Many supermarkets and high-street retailers also have battery recycling points. If your kit has a removable pod, empty it out first, and tape over the terminals on loose cells before handing them in.

Coils, pods and wicking technology

The coil is where liquid becomes vapour, and the coil type has a bigger effect on how a nic salt tastes than almost anything else. For a 20mg salt, you want a higher-resistance coil that runs at low power. Here are the common options and where each fits.

• Standard round-wire coils with cotton wicking: the traditional choice, with resistances around 0.8 to 1.2 ohm for pod systems. They give clean flavour but need good priming.
• Mesh coils: a flat mesh of metal wire provides a wider heating surface, which can improve flavour consistency and speed up ramp-up. In pod form, mesh coils are often around 0.6 to 1.0 ohm. They work well with sweet, creamy liquids because of the even heating, though they can use liquid a little faster.
• Ceramic coils: a ceramic heating element that resists dry hits and can give a cooler, cleaner taste, but is slower to warm up and may mute some flavours slightly.

Matching coil to liquid. For a banana custard salt, a coil of about 0.8 to 1.2 ohm running between roughly 8 and 15 watts is a sensible starting point. If your kit has a lower-resistance mesh coil, like 0.6 ohm, drop the power a little and keep your draws shorter. A coil designed for sub-ohm vaping, which is below 1.0 ohm and usually used with 3mg to 6mg freebase liquids, is the wrong hardware for 20mg salts. The nicotine delivery would be far too much.

Priming a new coil. This step is where most poor flavour begins. After fitting a new pod or coil, let it sit full of liquid for 5 to 10 minutes so the cotton soaks through. Then take two or three gentle draws without pressing the fire button, so the wick draws liquid in before heat is applied. Skipping this is the most common cause of a burnt taste on a new coil.

Coil lifespan. Sweet, creamy dessert liquids caramelise on the coil as they are heated, so expect a lifespan that is shorter than for a tobacco or menthol liquid. As a rule of thumb, a pod or coil used with a custard salt may last between one and two weeks of regular use, but that depends on your power and puff habits. Replace it when the flavour turns flat, burnt or muted, not when it fails completely.

Do not mix up your hardware. Refilling a pre-filled disposable pod or a kit not designed for refilling is unsafe and may damage the device. Use a device made to be refilled and check the manufacturer's guidance on liquid types and compatible strengths.

Choosing your nicotine strength

This bottle is 20mg/ml, which is the highest strength allowed in the UK for e-liquid, and the same cap applies to disposables and pods. It is the top of the range, not a default to reach for. Choosing the right strength is the single biggest factor in whether vaping feels satisfying or unpleasant.

As a general guide, the nicotine strength you need depends on how much you currently smoke or vape and which device you use. These are common starting points, not medical advice:

• Heavy smokers (around 20 or more cigarettes a day): 20mg salts in a pod kit are the usual starting point. This is the group the strength is designed for.
• Moderate smokers (around 10 to 15 a day): many people start at 10mg to 12mg salts. A 20mg bottle may feel too strong, causing dizziness or nausea.
• Light or social smokers: 5mg to 10mg salts or a low-strength freebase is usually enough. 20mg is unlikely to be needed.
• Current vapers using 3mg to 6mg freebase: switching to 20mg salt is a very large jump. Look at lower salt strengths first.

Signs the strength is too high. Lightheadedness, nausea, headaches, a racing heart, an unpleasant harsh throat hit or a feeling of being stuffed after a few puffs all suggest you are taking in more nicotine than you want. Stop, drink water and have something to eat. If it happens regularly, move to a lower strength.

Signs the strength is too low. Cravings returning within minutes, chain vaping or reaching for a cigarette suggest a higher strength or a more efficient device may help. Going up in small steps is better than jumping straight to the top.

Why salts are different. A 20mg freebase liquid is very harsh, which is why freebase is normally sold at much lower strengths for use in high-power tanks. Nic salts use a different form of nicotine that is smoother, so the same 20mg is easier to inhale at low power. The smoothness can lead new users to take more than they intend, so pace yourself.

If you are trying to quit smoking altogether, a stop-smoking service can offer support and advice. NHS stop smoking services in England and equivalent services in Scotland, Wales and Northern Ireland offer free help, and many include advice on vaping as a way to stop. If you are pregnant, have a heart condition or take medication, speak to a doctor or pharmacist before using nicotine products.

Who Zeus Bolt Banana Custard is for, and who should pass

Good fit for:

• Adult smokers moving to vaping who smoke around a pack a day and need a strength that matches their habit.
• Existing pod kit users who like dessert flavours and want a creamy alternative to fruit-and-ice.
• Vapers leaving disposables who want to refill rather than throw away a device every few days, and who are used to the 20mg strength of disposables.
• Flavour-led vapers who prefer sweet, filling profiles and use low-power hardware.
• Evening vapers who use a richer flavour at the end of the day and a lighter one earlier on.

Think twice if:

• You have never smoked or vaped. Nicotine is addictive and these products are intended for adults who already use nicotine.
• You are under 18. It is illegal to sell nicotine vapes to under-18s in the UK, and we do not sell to them.
• You smoke fewer than around 10 cigarettes a day. A lower strength will probably suit you better.
• You use a sub-ohm tank or a high-wattage mod. A 20mg salt is the wrong match. Look at 3mg to 6mg freebase or shortfill liquids instead.
• You dislike sweet or creamy flavours. A banana custard salt is not subtle, and it will taste sweet.
• You are pregnant or breastfeeding, or have a heart condition. Speak to a health professional first.

A note on dessert flavours and young people. Sweet flavours are often cited in discussions of youth vaping, and UK rules on flavours and marketing are under review. We sell to adults only and we expect age checks at delivery. If you buy for someone under 18, it is illegal and we ask you not to.

Using it as a stop-smoking tool. Many UK adults use vaping to cut down or quit cigarettes. If that is your goal, the best results come from switching fully rather than mixing cigarettes and vapes, and from picking a nicotine strength that keeps cravings manageable. A 20mg salt can serve that purpose for a heavier smoker, and the plan should usually be to step the strength down over time as cravings fade.

If banana custard is not quite what you are after, the same shop carries other flavours in nic salt, from fruit and ice to tobacco and menthol. Pick a flavour you are happy with for a full day, because a flavour you enjoy is easier to stick with.

How to use and fill your device

Filling a pod kit is simple, but small mistakes cause leaks and poor flavour. Follow these steps for a clean fill.

• Check your device is switched off and, if it has a removable pod, take the pod out.
• Wash and dry your hands. Nicotine can irritate skin, and a dry pod fills more cleanly.
• Open the bottle cap using the child-resistant mechanism, and keep the bottle upright.
• Find the fill port. It is usually a small rubber bung or sliding cover on the side or the bottom of the pod. Open it.
• Insert the nozzle and squeeze gently. Fill slowly, to just below the maximum line or the top. Never cover or fill the central airflow tube.
• Close the port fully and wipe away any liquid from the outside of the pod.
• Wait 5 to 10 minutes before the first puff so the coil is saturated.
• Take a few gentle draws without pressing the button, then start vaping normally.

How to vape nic salts. Use a mouth-to-lung draw: hold the vapour in your mouth for a second, then inhale. Draw for about 2 to 3 seconds rather than long, deep pulls. Take your time between puffs. Nic salts at 20mg can overwhelm you if you chain vape, so pause and see how you feel after the first few draws.

Looking after your kit.

• Top up before the pod runs dry. Running a coil with little liquid causes dry hits and shortens coil life.
• Keep the device upright when carrying, and with the mouthpiece covered if possible.
• Clean the contacts occasionally with a dry cotton bud so the battery connects well.
• Do not mix different liquids in the same pod. Flush and rinse, or replace the pod, when you change flavours.
• Replace the pod or coil on a regular schedule, rather than waiting for it to fail.

Travelling. Keep nicotine liquid in its original container in your hand luggage or a sealed bag. Liquid is limited by the usual airline rules, and pressure changes can push liquid out of a pod, so empty or seal pods before flying. Check the rules of any destination country before you travel, as vape laws differ widely.

Safety. Keep nicotine liquid away from children and pets. If liquid touches your skin, wash it off with soap and water. If it gets in your eyes or is swallowed, seek medical advice immediately and show the bottle. In the UK, call 111 or 999 in an emergency.

Troubleshooting common problems

Most problems with a nic salt kit come down to priming, power or coil age. Use this list to narrow down the cause before assuming anything is wrong with the liquid.

• Burnt or acrid taste: usually a dry hit from a coil that has not soaked. Let the pod sit, prime it, shorten your draws and lower the power. If the taste persists, replace the coil, because a burnt coil does not recover.
• Weak or muted flavour: often an ageing coil, especially with sweet liquids. Replace the pod or coil. Also check the battery level, because a low battery can reduce output.
• Gurgling or spitting: too much liquid in the chamber or condensation in the mouthpiece. Wipe it out and puff gently to clear it. Do not overfill.
• Leaking: a pod that is overfilled, cracked or poorly seated can leak. Check the seal and fill only to the line. Store the kit upright.
• Device will not fire: check that the pod is seated properly, the contacts are clean and the battery is charged. Some devices lock after repeated presses, so check the manual.
• Throat feels too harsh: lower the power, shorten your draws, or consider a lower nicotine strength.
• Dizziness or nausea: you may be taking in too much nicotine. Stop, rest, have water and food, and move to a lower strength next time.
• Sticky residue on the pod: normal with sweet liquids, so wipe the outside of the pod and contacts regularly.
• Liquid has changed colour: a slow darkening is normal over months. If it smells unpleasant or tastes wrong, stop using it.

Vaper's tongue. If your favourite flavour suddenly tastes like nothing, you may be experiencing temporary taste fatigue. Switch to a different flavour for a day or two, drink water, brush your tongue and come back to it. This is common with dessert and sweet flavours.

When to stop and contact support. If a battery gets hot, swells, smells of chemicals or leaks, stop using the device, move it away from anything flammable and contact the manufacturer. If you receive a bottle with a broken seal, a leaking cap or an incorrect label, do not use it and get in touch with us. Keep the packaging and a photo, and we will help.

Value for money

Price changes, so check the current figure on this page. What we can do is explain how to judge value for a 10ml nic salt bottle, which is more useful than a single number that may be out of date by the time you read it.

Compare cost per ml. Divide the price by 10 to get the cost per millilitre. Nic salts sit in a fairly tight price band across the UK market, so a bottle that is far cheaper or far more expensive than the norm is worth a closer look at the label and the seller.

Compare with disposables. Disposable vapes were typically sold with 2ml of liquid at 20mg/ml. A 10ml bottle contains the equivalent of about five of those in liquid terms. Even allowing for the cost of a pod kit and replacement pods, refilling is normally cheaper per puff over a few weeks. Refillables also generate far less waste, and the sale of single-use vapes has been banned in the UK since 1 June 2025.

Compare with cigarettes. Heavy smokers often find that the total weekly cost of vaping, including liquid, pods and device replacement, comes out well below the cost of cigarettes. Your own figure depends on how much you vape, so track your first few weeks to find out.

• What you are paying for: the flavour recipe, the nicotine, the bottle and compliance with UK labelling and notification rules.
• What can reduce cost: multi-buy offers, buying only the strength you need, and using a coil that runs at the right power so it lasts.
• What raises cost: buying higher strength than you need and using it faster, short coil life from vaping at too high a wattage, and buying lots of different flavours you do not finish.

Buying sensibly. If you have not tried the flavour, buy one bottle rather than a stack. Dessert flavours are subjective, and a flavour you do not enjoy is poor value at any price. Once you know you like it, a multi-buy can lower the per-bottle price.

Shelf life. Nic salts keep for a long time when stored properly, but they do not last forever. Check the best-before date and avoid stocking up more than you will use in a few months. Unopened bottles in a cool dark place hold their flavour and strength far better than a half-used bottle left on a windowsill.

How it compares with other options

Banana custard in a 10ml 20mg nic salt is a well-trodden category. Several established brands sell similar bottles, including IVG Salt, Nasty Salt, Elfliq, Dinner Lady and Pod Salt. We are not saying Zeus Bolt outperforms any of them. We have not tested every competitor flavour against this one, and taste is personal, so here are the fair points of comparison.

• Nicotine and bottle size: identical across the category. 20mg/ml in 10ml is the UK ceiling, so all legal 20mg salts match on this, and the difference is in the recipe.
• Flavour style: some brands lean towards a lighter, milkier custard, others towards a thicker, buttery one. Banana can range from candy-sweet to closer to real fruit. If you have a preferred brand, a Zeus flavour may taste a little different from the one you know.
• Price: mainstream nic salts sit in a similar band. Look at cost per ml and any multi-buy offers rather than headline prices.
• Range and availability: larger brands tend to have wider flavour ranges and are easy to find in high-street shops. A smaller range such as Bolt may have fewer flavours but could suit you if you like a particular one.

Versus a disposable vape. A disposable is convenient but no longer available to buy in the UK, and it cannot be refilled. A refillable kit with this liquid costs more upfront, lets you pick your flavour and strength, and produces less electronic waste. The trade-off is the small amount of maintenance involved: filling, priming and replacing coils.

Versus 10mg or 5mg salts. Lower strengths are gentler and last longer in terms of nicotine per day, but they may leave a heavy smoker unsatisfied. If you are in doubt, lower is usually the safer first purchase because you can always step up.

Versus freebase shortfills. Shortfills are large bottles of nicotine-free liquid designed for sub-ohm tanks, with a nicotine shot added by the user. They give bigger clouds and cost less per ml, but they require mixing and a more powerful device. If your kit is a pod, a salt is the better fit. If you vape on a sub-ohm tank, shortfills are the right choice.

Versus nicotine replacement therapy. Patches, gum and inhalators are licensed stop-smoking aids and are available through the NHS and pharmacies. Vaping is not a licensed medicine, though many adults use it to quit. Some people use both. A stop-smoking adviser can help you decide what suits you.

Our view. Zeus Bolt Banana Custard is a sensible option for an adult smoker or vaper who wants a dessert flavour in a standard UK 20mg salt, and who has pod hardware to use it in. It is not a reason to switch brand if you are happy with your current flavour, and it is not for sub-ohm users or for anyone who does not already use nicotine.
