Ohm Brew Badass Blend Killa Kola 50ml: overview

Ohm Brew Badass Blend Killa Kola is a 50ml shortfill e-liquid from the Ohm Brew Badass Blend range, made for vapers who use sub-ohm tanks and higher-wattage kits and would rather work through one large bottle of a single flavour than a drawer full of 10ml refills. The flavour is a cola profile: a dark, caramel-leaning sweetness with a citrus-tinged fizz impression on the inhale. Think of a glass of cola over ice rather than a fruit juice, although in most e-liquids of this type the sweetness sits a little closer to the confectionery side than the soft drink side.

This page is written for UK buyers and covers the questions that usually come up before an order: what is in the bottle, how much nicotine you can add, which devices suit it, how it compares with other 50ml options, and what to do when something goes wrong. We have kept to what can be reasoned from the product type and the range, and where a detail can vary between batches we say so and point you back to the label printed on your own bottle.

Key facts at a glance:

• Product type: 50ml shortfill e-liquid, supplied without nicotine
• Flavour family: cola, sweet and slightly citrus
• Typical base: high VG, in the region of 70% VG and 30% PG
• Bottle size: 60ml bottle with room for one 10ml nicotine shot
• Best suited to: sub-ohm tanks, mesh coil tanks and open pod systems that cope with thicker liquid
• Age restriction: 18 and over

It is worth being clear about what a shortfill is, because it trips up people who are used to disposables or pre-filled pods. A shortfill is a bottle of flavoured liquid that holds less than its full capacity so that you can top it up with nicotine shots to the strength you want. The bottle on its own contains no nicotine. It is not a device, it has no battery and no coil, and it will not do anything until you pair it with a refillable tank or pod kit.

For people who enjoy cola flavours, the appeal is simple. Cola is a familiar taste, it pairs well with cool air from a mesh coil, and a large bottle means you can settle into one flavour for a few weeks without reordering. For people who prefer a different style, the rest of this page should help you decide quickly whether this is the right bottle for you or whether you would be happier with something else.

Flavour profile: what Killa Kola actually tastes like

Cola is one of the more complicated flavours to recreate in an e-liquid, because the drink itself is a blend of many small notes rather than one dominant taste. Flavour houses usually break it into three layers, and it helps to think about Killa Kola in the same way.

The first layer is the sweet, dark base. This is a caramel-like, slightly burnt-sugar note that gives cola its colour and its rounded body. On the inhale you should expect this to arrive first, soft and sweet, without the sharpness of a fruit juice. The second layer is the citrus edge. Most cola recipes lean on a hint of lime, lemon or orange to lift the sweetness and give the impression of fizz. In a vape this reads as a light, slightly tart brightness at the front of the palate rather than a distinct fruit flavour. The third layer is the spice and vanilla finish, a faint warmth that lingers after you exhale.

Here is how we would expect a typical session to feel:

• First few puffs: sweet caramel and a clean citrus lift, the cola character is clearest here
• Middle of a tank: the flavours settle and blend, the sweetness feels rounder and the citrus note softens
• Exhale and aftertaste: a gentle vanilla-spice finish that fades fairly quickly, leaving a mildly sweet mouth

A few honest caveats. No e-liquid can reproduce the carbonation of a fizzy drink, so you are getting the flavour of cola rather than the sensation of bubbles. Some people also find that cola profiles taste a touch more like cola sweets than a canned drink, especially at higher wattages. And because the exact balance of citrus and spice differs between brands and sometimes between batches, your first tank may taste slightly different from what you remember from another cola juice.

This flavour is not described as a menthol or ice blend. If you want a chilled finish you can add a few drops of a separate cooling additive, but we would suggest trying the bottle as supplied first. Sweet liquids such as this one also build residue on coils faster than unflavoured or tobacco-style liquids, which is a point we return to in the troubleshooting section.

Finally, steeping. High-VG shortfills often taste slightly thin straight from the bottle because the flavouring has not fully blended with the base. Shaking well and resting the bottle for a day or two usually rounds the flavour out noticeably, and cola profiles in particular tend to taste smoother and less sharp after a short rest.

Specifications and bottle design

Here are the specifications that matter when you are comparing this bottle with others. E-liquid specifications can differ slightly by batch, so always check the printed label on your bottle for the exact VG/PG split and ingredient list.

• Liquid volume: 50ml
• Bottle capacity: 60ml, leaving 10ml of space for a nicotine shot
• Nicotine as supplied: 0mg/ml
• VG/PG: shortfills in this style are normally high-VG, in the region of 70% VG and 30% PG, which suits sub-ohm and low-resistance tanks
• Flavour category: cola with a sweet, slightly citrus profile
• Intended hardware: sub-ohm tanks, refillable tanks and pod devices that handle thicker liquid
• Minimum age: 18

On build quality, the packaging for a 50ml shortfill is practical rather than glamorous. You get a soft plastic bottle with a narrow nozzle designed for filling small tank ports without spilling. The nozzle is usually a fine tip, and the cap is a child-resistant closure, which is a legal requirement for nicotine-containing e-liquid and standard on shortfill bottles as well. The bottle walls are squeezable so you can control the flow, and the 60ml size gives enough headspace to add a shot and shake without the liquid overflowing.

The label carries the information UK law expects: product name, volume, ingredients, warnings, batch code and, where a nicotine shot has been added, the final strength that you should write on the bottle yourself. We recommend you do exactly that. Writing the resulting strength and the date in marker pen on the bottle is a simple habit that avoids confusion if you keep several flavours on the go.

One note on what a bottle like this does not include. It has no battery, no coil and no charging port. Everything in the performance and power sections below refers to the hardware you choose to pair the liquid with, not to the bottle itself. The bottle is also not designed for travelling light. At 60ml it takes up more room in a bag than a 10ml bottle, so many vapers decant into a smaller dropper bottle for daily carry and keep the large one at home.

The artwork follows the Badass Blend range look, with the flavour name printed clearly on the front so you can tell it apart from other bottles in a drawer. A dark label suits a cola flavour well, and the name should be easy to spot if you keep several variants.

Performance and vapour delivery

Because this is a high-VG liquid, performance depends heavily on the device you use it in, but the general pattern is predictable. VG, or vegetable glycerine, is the component that produces thick vapour. PG, or propylene glycol, carries flavour and gives a slightly stronger throat sensation. A 70/30 split leans towards big, smooth vapour with a softer throat hit, which is why this style of bottle is associated with sub-ohm vaping.

What you can expect in practice:

• Vapour production: dense and cloud-oriented on a sub-ohm tank at 40W to 80W, noticeably lighter on a low-power pod device
• Throat hit: soft at 0mg, mild at 3mg, with a more noticeable tickle if you push the wattage up
• Flavour intensity: strongest at moderate power, since very high wattage can burn off the delicate citrus note and leave the caramel sweetness dominant
• Draw style: mouth-to-lung or restricted-lung on a larger tank, with airflow opened up for cooler, airier hits

On a mesh coil tank, cola tends to taste cleaner and cooler, because mesh spreads heat evenly across a larger surface area. On a standard round-wire sub-ohm coil, the flavour may feel a little warmer and sweeter. Neither is better in itself; it comes down to whether you prefer a crisper or a rounder cola.

On longevity, a 50ml bottle is a lot of liquid. A typical sub-ohm user burns through somewhere between 3ml and 5ml a day, which puts a full bottle at roughly ten to sixteen days. Lighter vapers on pod devices can stretch it to a month or more. Those numbers are broad estimates, not a promise, and they move with wattage, airflow and how often you vape.

It is also worth being realistic about the nicotine side of performance. Because shortfills are limited to a single 10ml shot, the strongest mix you can reach is around 3mg/ml. That suits sub-ohm users who take large inhales and want a mild hit, but it will feel gentle to anyone who is used to 20mg/ml nic salt in a pod. If your priority is a strong nicotine hit in a small device, a nic salt e-liquid is a better match than this bottle.

For flavour-chasers, the main variables are coil condition and airflow. A fresh coil with moderate airflow gives the clearest cola taste, and the flavour drops off slowly as the coil ages and residue builds up.

Device pairing, battery and power considerations

There is no battery in the bottle, so power considerations are all about the device you choose. Matching the liquid to the right hardware makes the biggest difference to how this flavour performs, so it is worth spending a minute on this section.

The best-fitting hardware types are:

• Sub-ohm tanks (0.15 to 0.4 ohm): the natural home for a 70/30 shortfill, typically run between 40W and 90W depending on the coil rating
• Mesh coil tanks: good for even flavour and quick wicking of thick liquid
• Higher-resistance coils (0.6 to 1.0 ohm) on pod systems: workable if the pod is rated for high-VG liquid, run at low power
• Box mods and kits with replaceable cells: give you the headroom to run larger tanks comfortably

Battery life depends on wattage. As a rough rule, a device with a 3000mAh battery running a 0.3 ohm coil at 60W might give a day of moderate use, while the same battery on a low-power pod at 15W to 20W could last two to three days. Higher wattage drains the cell faster and also uses more liquid, so you will see a bottle disappear sooner on a powerful setup.

A few practical battery tips apply whichever device you use:

• Use the charger supplied with your device, or a reputable replacement, and avoid charging overnight on a soft surface
• Replace external lithium cells that are wrapped in damaged plastic
• Never carry loose cells in a pocket with keys or coins
• Do not leave a device in a hot car

If you are moving from a pod kit that previously ran 20mg nic salt, expect an adjustment period. A sub-ohm setup uses more power, produces more vapour and draws liquid faster. Start at the low end of the wattage range printed on your coil, and increase in small steps until the flavour is at its clearest without the vapour becoming hot or harsh.

If your device is a closed pod system with sealed pods, check the manufacturer guidance before filling anything. Many sealed systems are not designed for refilling, and using the wrong liquid in them can cause leaks or fail to wick properly. When in doubt, ask the shop which kit types suit a 70/30 shortfill.

Coil and mesh compatibility

Coil choice matters more with high-VG liquid than with thin salt nicotine liquids, because thick liquid needs to travel through the wicking material fast enough to keep up with the heating element. If the coil cannot wick quickly, you get dry hits and burnt flavour. Here is what generally works with a 70/30 cola shortfill.

• Mesh coils (0.15 to 0.3 ohm): large wicking surface, quick saturation, even heat. Usually the first choice for this style of liquid and the easiest way to get a clean cola flavour.
• Round-wire sub-ohm coils (0.2 to 0.5 ohm): reliable, slightly warmer vapour, and they usually have larger wicking holes that suit thick liquid.
• Higher-resistance regular coils (0.8 to 1.2 ohm): can work at low wattage, but thick liquid sometimes struggles to saturate smaller wicking holes, so go gently.
• Ceramic and cotton-free coils: variable results with high-VG liquids, so check the coil manufacturer guidance before relying on them.

Whatever you choose, prime the coil properly. This is the single most important habit for avoiding burnt hits. Drip a few drops of liquid directly onto the cotton through the coil holes, fill the tank, and wait at least five to ten minutes before the first puff. Thick liquid takes longer to soak into the cotton than thin liquid, and impatience is the cause of most early coil failures.

Sweet liquids such as cola shorten coil life compared with unsweetened flavours. Sweeteners can caramelise on the heating element, leaving a dark film that dulls flavour and eventually produces a burnt taste. Expect a coil to last somewhere between one and three weeks depending on wattage and how heavily you vape. If you notice flavour fading, replace the coil before blaming the liquid.

To get longer life, run the coil at the middle of its rated wattage range rather than the top, take slower and slightly longer draws rather than rapid chain puffs, and give the device a few seconds between puffs. Flush the tank and wash the base occasionally if you swap flavours, since old residue can mix with the new liquid and muddy the taste.

If you use a pod system rather than a tank, look for a pod labelled as suitable for high-VG or sub-ohm liquid. Pods built for thin salt nicotine liquid can leak or choke on 70/30 shortfill.

Nicotine strength: how to choose and how to mix

The 50ml bottle is supplied at 0mg. If you want nicotine, you add it yourself using nicotine shots, which are sold separately in 10ml bottles. This is a long-standing arrangement in the UK, and it exists because nicotine-containing e-liquid is capped at 20mg/ml and sold in bottles no larger than 10ml. The arithmetic is simple, so here is how it works.

• Add one 10ml shot of 18mg/ml (freebase) to the 50ml of liquid and you end up with 60ml at about 3mg/ml
• A 10ml shot at 20mg/ml gives roughly 3.3mg/ml
• With no shot, you stay at 0mg

The 60ml bottle only has room for one 10ml shot. If you need more than around 3mg, a shortfill is the wrong tool and a separate nicotine salt bottle is a more practical choice. That is an important point for former disposable users, whose devices typically delivered 20mg/ml nic salt. A shortfill mixed to 3mg will feel much milder than that, and on its own it may not satisfy cravings.

Here is a rough guide to who should choose what:

• 0mg: people who vape for flavour and habit only, ex-smokers who no longer need nicotine, and anyone stepping down
• 3mg: light to moderate vapers on sub-ohm tanks who want a mild nicotine hit with large vapour clouds
• Higher strengths: use a nic salt e-liquid designed for pod devices instead of a shortfill

How to mix safely: wash and dry your hands, open the shot, squeeze the contents into the 60ml bottle, close the cap firmly, and shake for around thirty seconds. Leave it for at least a few hours before first use, ideally overnight. Label the bottle with the new strength. Do not mix nicotine into a bottle that is already filled to the top, and do not pour shots near children or pets.

One more point for anyone who has used disposables. The 20mg/ml cap on UK nicotine products applies to the strength of the liquid, and it is the same figure you will see on many pod refills. Do not assume that a 3mg shortfill delivers anything like the same hit, because the lower strength combined with larger vapour volume produces a very different experience.

If you are unsure how much nicotine you need, remember that too much produces headaches, nausea or dizziness, while too little leaves you reaching for the device more often. Start lower than you think and adjust. If you are using vaping to stop smoking, local NHS stop smoking services can offer free advice and support, and are worth a call.

Nicotine is addictive. This product is for adults who already smoke or vape, and it is not suitable for non-smokers, people under 18, or pregnant and breastfeeding women.

Who Killa Kola 50ml is for, and who should skip it

No e-liquid suits everyone, so here is an honest split between the people who are likely to enjoy this bottle and the people who would be better served by something else.

It is a good fit if you:

• Use a sub-ohm tank or mesh kit and want a large bottle of one flavour
• Already enjoy cola flavours in drinks and sweets
• Vape at 0mg or a light 3mg and care more about flavour and vapour than nicotine strength
• Want to lower your cost per millilitre compared with 10ml refills
• Prefer a sweet, non-menthol profile that is easy on the throat

You might want to skip it if you:

• Use a closed pod system with sealed pods that cannot be refilled
• Need 10mg to 20mg nicotine strength, since a single shot cannot reach that range in a 60ml bottle
• Dislike sweet flavours or find sweetness cloying after a few minutes
• Prefer cooling menthol or ice blends
• Want a low-maintenance device, since a refillable setup means priming coils, filling tanks and washing parts

Former smokers. If you are moving from cigarettes to vaping, a shortfill alone is rarely the right starting point. Most people in the first weeks benefit from a nic salt liquid at a higher strength in a simple pod kit. Once you are comfortable, a sub-ohm setup with a 3mg shortfill can be a pleasant step to a larger, flavour-led experience, and some people use it as a stepping stone to 0mg.

Flavour-led vapers. If you have been vaping for some time and want something different from fruit or menthol blends, a cola profile is a familiar change that does not feel like a gimmick. It can also work as a second flavour that you alternate with a fruit or ice blend to reduce palate fatigue.

People who are not vapers. This product is not for non-smokers, anyone under 18, or women who are pregnant or breastfeeding. If you have a heart condition, high blood pressure or a respiratory condition, speak to your GP or pharmacist before using nicotine products.

If you are on the fence, the practical test is simple: do you have, or are you willing to buy, a refillable sub-ohm tank? If yes, this bottle fits. If no, look at a pod-friendly nic salt liquid instead.

How to use: filling, steeping and your first tank

Using a shortfill for the first time takes a few extra steps compared with a disposable or a pre-filled pod, but once you have done it twice it becomes routine. Here is a straightforward process from sealed bottle to first puff.

• Step 1, decide on nicotine. If you want 3mg, add a 10ml nicotine shot to the bottle now, close the cap tightly and shake for around thirty seconds. If you are staying at 0mg, skip this step.
• Step 2, rest the bottle. Leave it upright in a cool, dark place for at least a few hours, ideally overnight. A day or two is better for flavour, since cola profiles tend to blend and smooth out with a little rest.
• Step 3, prepare the coil. Fit a new coil if the old one is tired. Drip a few drops of liquid onto the exposed cotton through the coil holes so that it is wet before it ever fires.
• Step 4, fill the tank. Open the fill port, tilt the tank slightly, and fill with the bottle nozzle, avoiding the central airflow tube. Stop below the maximum line. Close the port before turning the tank upright.
• Step 5, wait. Leave the filled tank for five to ten minutes so the thick liquid can soak into the cotton. This stage is the most commonly skipped and the most common cause of burnt hits.
• Step 6, set the power. Start at the lower end of the wattage range printed on the coil, take a few slow draws, and raise the power in small steps until the flavour is clear and the vapour is warm rather than hot.

For the first few puffs, take them slowly and without chain vaping. A coil needs a few draws to settle, and the flavour usually improves after the first couple of minutes. If the first puffs taste thin or slightly papery, it is typically the cotton still absorbing liquid, not a fault with the e-liquid.

Top up before the tank gets close to empty rather than letting the coil run low, because a half-dry coil is the second most common cause of burnt flavour. Between refills, keep the bottle capped and stored upright, and wipe the nozzle so that it does not get sticky.

If you change flavours, flush the tank with warm water, let it dry fully, and fit a fresh coil. Cola can leave a lingering sweet residue, and mixing it with another liquid in a used coil tends to produce muddy flavours. Keep a small clean cloth or tissue near your filling spot because a thick VG liquid leaves a film on surfaces, and a quick wipe after filling stops the sticky build-up.

Troubleshooting common problems

Most problems with a shortfill setup come down to the coil, the wattage or the filling process rather than the liquid itself. Here are the common ones and what usually fixes them.

• Burnt or acrid taste. Usually caused by an unprimed coil, a tank that was run too low, or wattage that is too high. Replace the coil, prime it properly, and lower the power.
• Weak or washed-out flavour. Often a tired coil with sweetener residue. Replace the coil. If the flavour is still flat, give the liquid a day to settle after shaking and try a slightly lower wattage.
• Gurgling and spitting. The tank is overfilled or there is condensation in the airflow. Tilt the device, clean the drip tip and blow gently through the tank to clear it.
• Leaking from the tank. Check that the base is tightened, the seals are seated properly and the fill port is shut. Thick liquid will expose a loose seal quickly. Leaking can also happen after flying or on a hot day when air expands, so keep the device upright.
• Dry hits. The coil is not wicking. Open the airflow slightly, lower the wattage, and wait a few more minutes after filling before you vape.
• Sore throat or cough. Often caused by too much power, tight airflow or too much nicotine. Lower the wattage, open the airflow and consider dropping to 0mg.
• Sticky bottle or device. A normal consequence of high-VG liquid. Wipe it down with a damp cloth and keep the nozzle clean.
• Liquid looks darker after a few weeks. Slight darkening is common with light, heat or age. It is usually harmless but check the best-before date and the aroma. If the liquid smells off, stop using it.

If you have tried these fixes and the problem persists, test the same liquid in a different tank or with a fresh coil. If it behaves properly there, your original device needs attention. If the same fault repeats across devices, contact the shop with your order number and a clear description. Please keep the bottle and batch code to hand, because they help trace the problem quickly.

Never keep using a device that overheats, smells of burning plastic, or has a swollen or damaged battery. Stop using it, switch it off, and take it to a recycling drop-off point or contact the manufacturer.

Value for money and how it compares with other 50ml shortfills

Value in vaping is not just the sticker price. It depends on how long the bottle lasts, how many coils you go through, and how much you enjoy the flavour. Here is how this bottle sits against the alternatives.

Against 10ml refills. Buying 50ml of a flavour usually works out cheaper per millilitre than five separate 10ml bottles, and you do not have to keep reordering. The trade-off is that you commit to one flavour for a long stretch, and you have to buy nicotine shots separately if you want any nicotine at all. If you add a shot, factor the cost of the shot into your calculation.

Against disposables. Disposable vapes are now banned from sale in Great Britain, so a refillable setup is the standard route for most people. A refillable device costs more up front but is cheaper to run over several months, and a large bottle means fewer repeat purchases. You also create less waste, since you only replace coils and bottles rather than the whole device.

Against other 50ml shortfills. This bottle sits in the same part of the market as other mid-priced 50ml ranges from established UK brands. Most 50ml shortfills share the same 70/30 base, the same 60ml bottle and the same nicotine shot arrangement, so the real difference is flavour. Where this bottle does well is a clear, recognisable cola profile that is not trying to be anything fancy. Where it may fall short for some people is in flavour range: if you want complex, multi-layered blends or heavy cooling, other ranges may offer more variety.

Against cola flavours in other ranges. Cola e-liquids vary quite a lot, with some leaning towards citrus soda, others towards sweet vanilla cola, and a few towards a spiced, drier profile. Killa Kola sits near the sweet, caramel-led end, so if you prefer a sharper, lemony cola, you may prefer another brand. We would suggest trying one bottle before committing to several.

A fair way to judge value: if you vape around 4ml a day, a 50ml bottle lasts about twelve days. Divide the bottle price by twelve and add the cost of a shot and about half a coil, and you get a realistic daily cost. For many people that figure beats both disposables and pre-filled pods. If the numbers do not stack up for your usage, it is better to find out before buying than after.

UK rules, storage, safety and recycling

Buying and using e-liquid in the UK comes with a few rules and good practices worth knowing, whether you are new to vaping or just new to shortfills.

Age and sales rules. You must be 18 or over to buy and use vaping products. Retailers, including online shops, must verify age. Nicotine-containing e-liquid in the UK is capped at 20mg/ml and sold in bottles of no more than 10ml, which is why this 50ml bottle is supplied with no nicotine and a separate shot is needed to add any. Single-use disposable vapes are banned from sale in Great Britain, so refillable and rechargeable devices are now the standard route.

Storage. Keep the bottle in a cool, dark place away from direct sunlight and heat sources such as radiators and car dashboards. Light and warmth darken the liquid and can alter the flavour over time. Keep the cap tight, store upright, and keep it well out of reach of children and pets. If you add a nicotine shot, treat the bottle as a nicotine product and store it accordingly.

Shelf life. Most e-liquids stay in good condition for a year or more when unopened and stored properly. Once opened, they are best used within a few months, and flavours can mellow or fade with time. Check the best-before date printed on the bottle.

Spills and accidents. Wipe up spills promptly. Wash skin that has come into contact with liquid. If a child or pet swallows e-liquid, or if you swallow nicotine yourself, seek medical help immediately and take the bottle with you.

Recycling. Empty e-liquid bottles are plastic and can usually go into household plastic recycling once rinsed and dry, but check your local council guidance, because rules differ. Devices, batteries and cells should never go in household bins or recycling. Instead, take them to a drop-off point. Many UK supermarkets, electrical retailers and council recycling centres accept small electrical items and batteries, and many vape shops operate take-back schemes. Damaged lithium cells should be dropped off with care, kept separate from other metal items.

If you are unsure about anything on the label, contact the shop before you use the product. A short question is always better than guessing.
