Bang 200ml Sour Watermelon Shortfill at a Glance

Bang 200ml Shortfill E-Liquid Sour Watermelon is a nicotine-free fruit e-liquid sold in a large bottle for £9.99, made by Bang and aimed at adults who already vape with a refillable tank or kit. It pairs two ideas that sit comfortably together in sweet shop flavours: the juicy, watery sweetness of ripe watermelon, and a tart, slightly puckering edge that stops the sweetness from becoming heavy. It arrives at 0mg, so there is no nicotine in the bottle as supplied.

If this style of bottle is new to you, the short version goes like this. A shortfill holds far more liquid than a standard 10ml bottle and is sold without nicotine so that it can be packaged in bulk. The container has spare headroom, which means you can add nicotine shots yourself for a low-strength mix, or simply leave it alone and vape it at 0mg. Either way you end up with a lot of flavoured liquid for a modest price, which is why shortfills have become the everyday choice for people who vape from a tank.

Bang produces a long run of 200ml flavours, from single fruits such as apple and blood orange to blends like strawberry kiwi and blueberry lemonade, and you can browse the whole range in our shortfill e-liquids collection. Sour Watermelon is the one for people who like fruit with a little bite. It is not a dessert flavour, not a menthol and not a tobacco, so if you are after any of those, other shelves will serve you better.

This page is a buyer's guide rather than a sales pitch. It covers how the format works, what the flavour is likely to taste like, how to choose a strength, which devices suit it, how to store a big bottle, where the product falls short, and what to expect from delivery. The facts we hold for this listing are the name, the brand, the price, the 0mg strength, the flavour and the shortfill format. Details that vary by batch, such as the exact bottle capacity and the VG and PG split, are printed on the label, and we do not guess at them here. You must be 18+ to buy this product.

How a Shortfill Bottle Actually Works

Why does a bottle holding 200ml of liquid come in a container that looks bigger than its contents? The answer is a quirk of UK rules and a clever workaround for them. Nicotine-containing e-liquid in the UK is limited to 10ml per bottle and to a maximum strength of 20mg/ml. Nicotine-free liquid is not held to the same container limit, so brands can sell it in far larger volumes. A shortfill is simply a big bottle of 0mg flavoured liquid, filled to less than its full capacity.

That unfilled space is the point. A 200ml shortfill is commonly supplied in a bottle of roughly 240ml, though you should always check the label on the one you receive, because that figure is the final word. The gap is sized to take nicotine shots, which are separate 10ml bottles of concentrated nicotine in a neutral base, usually sold at 18mg/ml or 20mg/ml. Pour in one, two, three or four, shake well, and you have a finished e-liquid at a strength you chose. Leave the gap empty and it stays at 0mg.

The arithmetic is straightforward. Four 18mg/ml shots in a 240ml bottle give 3mg/ml overall, because the shots add 40ml of liquid and 720mg of nicotine to the original 200ml. Fewer shots give proportionally less. That limits the format to a fairly low strength range, which suits the larger, airier devices these bottles are designed for.

The other benefit is value. One 200ml bottle replaces a long row of small bottles, the cost per millilitre falls sharply, and there is much less plastic to throw away. Large shortfills are also usually built with a higher proportion of vegetable glycerine, the thicker half of the base, because they are aimed at sub-ohm and mid-power setups that produce plenty of vapour. We do not quote a ratio for this product, so read the label if your device specifies one.

If you never intend to add nicotine, our nicotine-free e-liquids collection gathers every 0mg option in one place, which makes comparing flavours and sizes quicker.

What Sour Watermelon Tastes Like

Start with the fruit. On the inhale, expect a light, juicy watermelon: sweet, a little watery, and closer to the pink flesh at the centre of the slice than to the green rind. It is the kind of watermelon you find in fruit chews and fizzy sweets rather than the muted, almost cucumber-like note some cheaper flavourings produce.

The sourness arrives in the middle of the draw. Think of the tangy coating on a sour sweet: a brief, zippy sharpness that lifts the sweetness instead of replacing it. Most people notice it most on the first few puffs of a session, and it can seem to soften as your palate adjusts, which is normal for any tart flavour. On the exhale the watermelon sweetness returns and the tartness fades quickly, leaving a clean, fruity aftertaste without a heavy lingering coating.

Nothing in the product name suggests menthol or ice, so do not expect a chilled vape. If you like a cold finish you can pair this with a different bottle on rotation, but as supplied it is a straightforward, fruit-forward flavour. Flavour is subjective, and the way your device is set up changes how it comes across. Higher power tends to warm the vapour and push the sweetness forward, while a cooler, airier draw usually keeps the tartness crisper.

Adding nicotine shots can alter the balance slightly. The shots bring a small amount of their own base liquid and a gentle throat feel, which can take the edge off the tartness a little and make the sweetness seem rounder. If the sour note is what you bought the bottle for, mix lightly or leave it at 0mg.

Among Bang's fruit range, Sour Watermelon sits with the sharper, livelier flavours rather than the soft, mellow ones. If you already enjoy tangy apple or blood orange profiles, this is a natural step along. If you prefer pure, gentle sweetness, a straight single-fruit flavour may be easier to live with across a whole 200ml.

Who Should Buy It and Who Should Skip It

This bottle suits a particular kind of adult vaper, and it helps to be honest about who that is. It is for people who already use a refillable tank, a sub-ohm kit or a mid-power device, who go through a fair amount of liquid, and who enjoy sweet and sharp fruit flavours. It is not intended for anyone under 18, and it is not intended for people who do not already use nicotine products.

It is a good fit if you:

• refill a tank every day and want a lower cost per millilitre than small bottles offer
• like the idea of mixing your own strength with nicotine shots, or vaping at 0mg
• prefer fruit flavours with some tartness rather than pure sweetness
• are happy to store and handle a large bottle responsibly

You may want to look elsewhere if you:

• use a closed pod kit or a disposable device, because those are not designed to be refilled with a shortfill
• want a high nicotine strength in a compact, discreet draw, which is a different product category
• dislike sour flavours, in which case a milder fruit will be less tiring over a full bottle
• only want to try a flavour once before committing to a big bottle

That last point deserves a practical answer. Committing to 200ml of any flavour is a bigger decision than buying a 10ml bottle, and flavour fatigue is real. If you are curious but cautious, the 5 for £10 e-liquids range lets you sample several small bottles for a fixed price before you settle on a large one. Many customers do exactly that, then come back for a shortfill once they know what they like.

One further consideration is routine. If you tend to vape the same flavour all day, a single big bottle is ideal. If you like to switch every few days, you might prefer to buy two or three different 200ml flavours and rotate them, which keeps things interesting and spreads the cost.

Specifications, Price and Cost Per Millilitre

Here are the numbers that matter, set out plainly.

• Product: Bang 200ml Shortfill E-Liquid Sour Watermelon
• Brand: Bang
• Price: £9.99
• Format: shortfill e-liquid bottle, no device included
• Liquid volume: 200ml
• Nicotine as supplied: 0mg
• Flavour: Sour Watermelon
• Approximate cost per millilitre: just under 5p
• Bottle capacity and VG/PG split: as printed on the label of your bottle

The cost figure is plain division: £9.99 over 200ml comes to a little under 5p per millilitre. To put that in context, an illustrative 10ml bottle at £2.50 works out at 25p per millilitre, so the shortfill costs around a fifth as much for the same quantity of liquid, before you add any nicotine shots. Shots are a separate purchase, so factor that in if you plan to mix.

If you do mix, here is what you get assuming a 240ml bottle, 200ml of liquid and 10ml shots at 18mg/ml:

• No shots: 0mg in 200ml
• One shot: roughly 0.9mg in 210ml
• Two shots: roughly 1.6mg in 220ml
• Three shots: roughly 2.3mg in 230ml
• Four shots: exactly 3mg in 240ml

With 20mg/ml shots the results are a little higher, reaching about 3.3mg with four. Check your actual bottle size and shot strength before relying on these figures.

How long will it last? A moderate tank user getting through 3 to 5ml a day could make 200ml stretch to somewhere between 40 and 65 days. Someone vaping 10ml a day would finish it in about three weeks. These are rough estimates, because wattage, airflow and habit all change consumption. If you are buying several bottles at once, take a look at the current vape deals for any multibuy offers.

Adding Nicotine Shots: A Step by Step Walkthrough

Clear a flat surface first, and put down a tray or some kitchen roll. Mixing is simple, but nicotine liquid is not something you want on skin or carpet, and a tidy workspace prevents most of the usual mishaps. If you plan to vape at 0mg, you can skip this section entirely.

• Step 1, read the label. Confirm the bottle capacity and the strength of your shots. The label tells you how much empty space you have.
• Step 2, open the shortfill. Unscrew the childproof cap and lift out the nozzle if it comes away separately.
• Step 3, add the shots. Pour in only as many shots as your target strength needs, and never more than the empty space allows.
• Step 4, close it up. Refit the nozzle and tighten the cap fully before you do anything else.
• Step 5, shake well. A firm shake for a minute or two helps the nicotine disperse evenly through the thick base.
• Step 6, rest and shake again. Leave it for a few hours or overnight, then give it a final shake. Many people find the flavour is rounder after a short rest.
• Step 7, label it. Write the strength and date on the bottle so you are never guessing later.

A clean, dry funnel makes pouring easier, and good lighting helps you see what you are doing. Keep full and empty shot bottles away from children and pets, and only put empties in the recycling once they are drained and capped. If any liquid touches your skin, wash it off with soap and water straight away.

Mix the whole bottle in one go. Splitting shots across several smaller decants complicates the maths and makes errors easy. If it turns out slightly weaker or stronger than you wanted, note the result and adjust next time. Anything you are unsure about can be checked on our frequently asked questions page.

Choosing a Nicotine Strength for a 0mg Base

There is no universal right answer here, because the sensible strength depends on where you are starting from. A shortfill gives you a narrow, low range by design: from 0mg up to about 3mg when all four shots go in. That is the zone that sub-ohm and mid-power vaping was built around, because large clouds mean a lot of liquid passes through with every draw, so a lower concentration goes a long way.

As a loose guide, these bands are common, though preferences vary widely:

• 0mg: soft and smooth with no throat feel. It suits people who vape for the flavour and the habit rather than for nicotine.
• Around 1mg (one or two shots): a gentle throat feel, and a sensible midpoint if you are reducing from a higher strength.
• Around 2mg (two or three shots): a noticeable throat feel and a comfortable middle ground for many daily tank users.
• 3mg (four shots): the upper limit of this format, with a firmer throat feel.

Sour flavours deserve a short note. Tartness and throat feel are both sensations at the back of the mouth, so a higher strength combined with a sharp flavour can feel harsher than either alone. If you are mixing at 3mg and the result feels a bit rough, drop a shot next time rather than assuming the liquid is at fault.

If you are coming from a 20mg nicotine salt pod device, treat a sub-ohm shortfill as a different experience, not an equivalent one. Some people find the strongest mix is the closest match, while others still find it softer than they are used to. Resist the urge to force extra nicotine into a bottle beyond the available space. If what you really want is the compact, high-strength draw of a pod, nicotine salt e-liquids are formulated for that job and are a better fit.

Start lower than you think you need. You can add another shot later if there is room, but you cannot take nicotine back out once it is mixed. And if you do not currently use nicotine, there is no reason to add any.

Devices, Coils and Power Settings That Suit It

A shortfill is only as good as the tank it goes into. This bottle is built for refillable setups: sub-ohm tanks, mid-power tanks and many adjustable-wattage kits. Our vape kits range includes plenty of refillable options if you are still choosing a device. Closed pod systems and disposables are a different matter. They are made to be used as sealed units or to take their own matched pods, and pouring a shortfill into one that is not designed for it is a recipe for leaks and poor performance.

Check your device manual for any guidance on VG and PG ratios, since some small tanks and coils prefer thinner liquid, while others handle thick, VG-heavy blends without trouble. Compare that against the figures on your bottle label before filling.

Coils matter more than people expect with sweet and tangy flavours. Sugary fruit liquids tend to leave residue on a coil faster than lighter profiles, which can dull the taste and eventually cause a burnt note. Keep a few spare coils to hand and replace one as soon as the flavour starts to fade rather than pushing it for another tank. A new coil should be primed by dripping a little liquid onto the cotton and letting the tank sit for several minutes before the first draw.

On power, begin at the low end of the range printed on the coil and nudge upwards until the flavour feels right. Going higher makes the vapour hotter and larger, but it also burns through liquid faster and can mute delicate tartness. Most people find a middle setting gives the best balance for a fruity flavour like this one.

A word on batteries, since this affects the whole setup. Charge your device with the cable supplied or a reputable replacement, do not leave it charging unattended overnight, and stop using any battery that looks swollen, dented or damaged. Looking after the hardware keeps the whole experience safer and more enjoyable, and a healthy device makes the liquid taste better.

Storing a 200ml Bottle Without Spoiling It

Two hundred millilitres is a lot of liquid, and it will probably sit in your home for weeks, so storage is worth a few minutes of thought. The basics are simple. Keep the bottle upright, tightly capped, and in a cool, dark place such as a cupboard or a drawer. Sunlight and warmth speed up the changes that dull flavour and darken liquid, and a parked car or a sunny windowsill is about the worst place you could choose.

Keep it well away from children and pets. Even nicotine-free liquid is not something anyone should swallow, and once you add shots the bottle contains nicotine, so a secure, high shelf or a lockable box is sensible. Store any unused shots separately from the main bottle, and put mixed bottles back in their usual spot rather than leaving them on a desk.

A big bottle can be awkward to use directly at the tank, so many people decant a smaller amount into a clean, dry, labelled dropper bottle for daily use. If you do this, label it with the flavour and strength, and wash and dry the bottle thoroughly between uses so flavours do not mix. A funnel or a long nozzle reduces spills.

Shake the main bottle gently before each decant, particularly after you have added shots, because the thicker base can settle slightly over time. If the liquid darkens a little with age, that is not unusual for fruit flavours, but if it smells wrong or tastes off, stop using it.

Finally, check the label for any batch or best before information and use the older bottles first if you own several. Buying one flavour at a time and finishing it before opening the next is a simple habit that reduces waste. Wipe the neck and nozzle after use to keep the threads clean, and keep the cap tight, so the bottle stays tidy and the contents stay as you left them.

Honest Pros and Cons of This Bottle

No product suits everyone, so here is the balanced view.

What works in its favour:

• Value: just under 5p per millilitre at £9.99 is hard to beat with small bottles.
• Flexibility: you decide whether to vape at 0mg or mix to a low strength with shots.
• Flavour with character: the tart edge gives it more personality than a plain sweet fruit.
• Less packaging: one large bottle replaces many small ones.
• Familiar brand: Bang offers a deep range of 200ml flavours, so there is plenty to try next.

What counts against it:

• Not for every device: it is no use in disposables or closed pods that are not designed for refilling.
• Low strength ceiling: the format tops out at around 3mg, so it is not a match for high-strength pod use.
• Sourness is subjective: some people love it for a few puffs and tire of it across a full day.
• Extra cost for shots: mixing to a nicotine strength adds to the overall price.
• Handling: a large bottle needs sensible storage and careful decanting.

Weighing these up, the sensible reading is that this bottle works best for someone who already vapes from a tank, enjoys tangy fruit and is comfortable with a little DIY. It is a poor choice for a beginner who wants the simplest possible device, or for anyone expecting a creamy, dessert-style liquid.

For a fair comparison, think about how you would feel after the first few days. A flavour that is fun for a weekend can become wearing across three weeks. If you suspect you might be one of those people, buying a smaller sample first or rotating with a second flavour is a perfectly reasonable way to hedge. Nothing about this bottle is flawed, but fit matters more than any list of features.

Troubleshooting Flavour, Leaks and Coil Life

Most problems with a big shortfill come down to a handful of causes, and almost all of them are easy to fix. Work through these in order before blaming the liquid.

• The flavour seems weak. This is often a tired coil, a freshly mixed bottle that needs a rest, or palate fatigue after vaping the same taste all day. Shake the bottle, give it a few hours, change the coil if it is old, and try a different flavour for a day.
• A burnt or harsh taste. Usually a coil that has been dry primed, a tank that has run low, or power set too high. Refill, prime a new coil properly, and lower the wattage.
• Gurgling or spitting. Often caused by overfilling, too much liquid in the wick area, or airflow set too tight. Fill below the maximum line and open the airflow a little.
• Leaking from the tank. Check that every seal is seated, the tank is screwed together tightly, and you have not filled past the line. Store the device upright.
• A sticky bottle or nozzle. Wipe the neck after each use, and keep the cap on between refills.
• The sourness feels too sharp. Lower the power slightly, try a larger airflow, or if you have added shots, remember a smaller number next time.

It also helps to know how a sweet liquid behaves over a bottle's lifetime. Fruit flavours leave residue, so expect to replace coils more often than you would with a plain tobacco or mint. That is normal, not a fault. Rinsing the tank between flavours also prevents muddled tastes.

If you have tried all of this and something still seems wrong with the liquid itself, such as an odd smell, a strange texture or a damaged seal, stop using it and get in touch.

Value, Delivery and Returns in Brief

Buying a large bottle online should be straightforward, so here is how it works. At £9.99 for 200ml, the value argument is simple: under 5p per millilitre before any nicotine shots. Prices can change, so check the live product page for the current figure.

On delivery, UK orders over £20 qualify for free delivery, and orders placed before 4pm are dispatched the same day, which is handy when you are running low on liquid. Smaller baskets, timings and costs are covered in full on our shipping information page, which is also the place to check the current returns wording before you order.

Because vaping products are restricted to adults, you must be 18+ to buy this e-liquid. You may be asked to confirm your age at checkout or on delivery, and the age verification page explains how the process works. An order that cannot be age-verified may be held up, so it is worth reading before you buy.

All stock sold here is 100% genuine, sourced for the UK market. If your parcel arrives damaged or you receive the wrong item, tell the team promptly with your order number and a photograph, and they will help put it right. As with most consumable products, opened or mixed bottles are harder to return than sealed ones, so check the label and the contents on arrival before you add any shots. That takes a minute and avoids any complication later.

To recap: Bang 200ml Sour Watermelon is a lively, tangy fruit e-liquid in a large, cost-efficient bottle, aimed squarely at adults who already use refillable tanks and kits. Choose your strength carefully, match it to the right device, store it sensibly, look after your coils and it should keep you supplied for many weeks of steady use.
