How Long Does a 100ml Bottle of E-Liquid Last the Average UK Vaper?
Only got a minute?
- A 100ml bottle lasts most UK vapers 10 to 30 days. Divide 100 by the millilitres you get through in a day and you have your answer.
- The device decides almost everything. A pod kit sipping 3ml a day stretches a bottle past a month. A sub-ohm tank on 10ml a day empties it in ten.
- Low-resistance coils and high wattage burn liquid fastest. Sub-ohm coils below 0.5Ω can use three times what a 1.0Ω pod coil uses.
- Buying in 100ml costs less per ml than buying the same volume in 10ml bottles, and that stays true after the vape duty because the tax is flat per millilitre. Browse the shortfill range.
- A 100ml is a shortfill, so it arrives at 0mg in a 120ml bottle with room for two nic shots to take it to roughly 3mg.
The short answer: ten days to about a month
There is no single figure, but there is a reliable range. Ask a hundred UK vapers how long a 100ml bottle lasts and the answers cluster between ten days and a month. That spread is not random. It tracks almost exactly with how much vapour the device makes, because vapour is liquid that has been turned into mist and inhaled.
The arithmetic is simple once you know your daily consumption. A bottle is 100ml of liquid, so a bottle lasts 100 divided by your daily millilitres. The hard part is knowing your daily figure, and most people have never measured it. The quickest way is to fill your tank or pod from a fresh 10ml bottle and count the days until it runs dry. If it takes five days, you use 2ml a day. If it lasts two days, you use 5ml a day.
| Daily use | A 100ml lasts | Typical setup |
|---|---|---|
| 2ml a day | About 50 days | Light pod kit user on a high nicotine strength |
| 3ml a day | About 33 days | Everyday pod kit or mouth-to-lung tank |
| 5ml a day | About 20 days | Heavier pod use, or a low-power tank at 20W |
| 7ml a day | About 14 days | Sub-ohm tank used moderately |
| 10ml a day | About 10 days | Sub-ohm tank on a mod, all day, big clouds |
A 100ml shortfill is sold in a 120ml bottle. Once you add two 10ml nic shots you actually have 120ml to vape, so add another 20 per cent to every figure above.
What changes the number
Five things move the figure up or down, and they compound. A high-wattage mod with a low-resistance coil and a 3mg liquid can get through four times what a pod kit with a 1.0Ω coil and a 20mg nic salt uses in the same day.
| Factor | Effect on bottle life |
|---|---|
| Device wattage | Higher wattage vaporises more liquid per puff. Going from 15W to 60W roughly triples consumption. |
| Coil resistance | Low-resistance sub-ohm coils wick and fire far more liquid than high-resistance mouth-to-lung coils. |
| Nicotine strength | Higher strengths satisfy sooner, so you vape less. Low strengths often mean more puffs to feel the same. |
| Puff frequency | Constant grazing empties a tank quickly. Short, deliberate sessions stretch a bottle a long way. |
| Flavour preference | Sweet and icy flavours invite more puffs. A plain tobacco is usually vaped more sparingly. |
Nicotine strength is the one people forget. If you have dropped from 20mg to 6mg because you wanted a smoother inhale, expect your liquid consumption to climb, because your body is chasing the same nicotine through more vapour. Our guide to how much nicotine you should vape covers how to pick a strength that actually settles cravings.

Your device decides almost everything
If you only look at one thing on this page, look at what you are vaping on. The difference between a pod kit and a sub-ohm tank is bigger than every other factor put together.
Pod kits
Low wattage, small pods, coils of 0.6Ω and above. Efficient by design, usually run with higher nicotine. Expect 2ml to 5ml a day and a 100ml that lasts the best part of a month.
Sub-ohm tanks
High wattage, big airflow, coils below 0.5Ω. Heavy vapour and very strong flavour, at a cost. Expect 7ml to 12ml a day and a 100ml gone in ten days to a fortnight.
| Feature | Pod devices | Sub-ohm devices |
|---|---|---|
| E-liquid consumption | Low | High |
| Power output | Low wattage | High wattage |
| Vapour production | Moderate | Heavy |
| Flavour intensity | Good | Very strong |
| Bottle lifespan | Longer | Shorter |
| Best for | Everyday use and efficiency | Cloud production and stronger flavour |
Neither is better, they are different jobs. If running costs matter to you, a pod kit on a 50/50 liquid is the cheaper way to vape all day, and it is the setup most ex-smokers get on with. If you want flavour and vapour above all else, a sub-ohm tank delivers it and you accept that the bottle empties faster. If you are not sure which camp you are in, our guide to choosing a vape by inhalation style is the place to start.
Coil resistance and wattage in practice
Coil resistance is measured in ohms, and it sets how much power the coil draws and how much liquid it turns to vapour. A 1.2Ω mouth-to-lung coil at 12W sips. A 0.15Ω mesh coil at 70W drinks. Same bottle, wildly different lifespan.
As a rough guide, a 1.0Ω to 1.2Ω pod coil uses around 2ml to 3ml a day in normal use. A 0.6Ω to 0.8Ω coil, which is what most modern pod kits ship with, sits nearer 4ml to 6ml. Drop below 0.5Ω on a sub-ohm tank and you are in 8ml to 12ml territory. That is the entire ten-to-thirty-day spread explained in one specification.
Coil condition matters too. A worn coil stops wicking evenly, tastes muted and tempts you into longer, more frequent puffs to get the same hit, which quietly increases how much liquid you use. Replacing a coil on schedule is cheaper than vaping your way through an extra bottle chasing flavour that is not coming back. Leaking has the same effect from the other direction, and a tank that weeps liquid into the airflow can waste a surprising amount over a week. If that sounds familiar, read how to stop e-liquid device leaks.
Does flavour really change how much you use?
It does, and more than people expect. Sweet, icy and dessert flavours are moreish. They taste good enough that you keep going back between cravings, and those extra puffs add up over a fortnight. Plain tobacco and light menthol tend to get vaped to satisfy a craving and then put down.
There is a practical angle here as well. A flavour you are only lukewarm about is a flavour you will vape absent-mindedly without ever feeling finished, which is the worst of both worlds. Buying a 10ml of a flavour before committing to a 100ml of it is the cheapest quality-control step there is, and the 10ml range exists partly for that reason.
Popular 100ml choices at the moment run from berry profiles like Blue Razz Berry by Seriously Fruity through to the 500ml staples such as Kingston Zingberry for people who already know what they like. The whole e-liquid range is worth a browse before you settle.
Why the 100ml bottle is the value buy
A 100ml shortfill gives you the same volume as ten 10ml bottles at a noticeably lower cost per millilitre, plus one cap to open instead of ten and a fraction of the packaging. For anyone vaping daily, that is the whole argument. Shortfills arrive at 0mg nicotine in a 120ml bottle with 20ml of headroom, so two 18mg nic shots bring the full 120ml to roughly 3mg. If the format is new to you, our shortfill vs 10ml e-liquid guide explains exactly which one suits your kit and strength.
The one thing a shortfill cannot do is high strength. UK law limits nicotine-containing bottles to 10ml and 20mg/ml, so if you need salt-level nicotine you stay on 10ml nic salts and accept the higher cost per ml. That trade-off is the reason plenty of people keep both formats on the shelf: salts in the pod for the morning, a shortfill in the tank for the evening.
| Benefit of a 100ml | What it means day to day |
|---|---|
| Better value per ml | Lower cost per millilitre than buying the same volume in 10ml bottles |
| Fewer orders | One bottle covers weeks, so you are not reordering every few days |
| Less packaging | One bottle and one cap instead of ten of each |
| Consistent flavour | Same batch from first fill to last, with no variation between bottles |
| Control over strength | Add one shot or two and land where you want, rather than taking a fixed strength |
Cost is about to matter more. From 1 October 2026 the Vaping Products Duty adds £2.20 per 10ml plus VAT to every bottle of e-liquid, nicotine or not, which is £2.64 per 10ml at the till. A 100ml shortfill with two shots is 120ml of finished liquid, so it carries £31.68 of duty. That is a large number, but the duty is flat per millilitre, which means it lands identically whether you buy one 100ml or ten 10ml bottles. The bottle with the lower base price per ml stays the cheaper option, and the gap simply narrows in percentage terms. Stock held before 1 October can be sold at pre-duty prices until 31 March 2027, so if you already know your flavour there is a case for buying the bottle you would have bought anyway.
If you want to go further than 100ml, longfill e-liquid is the concentrate-based route to large volumes, and it works out cheaper again for anyone happy to mix.
How to make a 100ml last longer
You cannot change the physics, but you can stop wasting liquid. These five habits routinely add a week to a bottle.
- 1
Get the nicotine strength right. Being slightly under-nicotined is the most common cause of heavy liquid use. Two shots in a 100ml give roughly 3mg, which suits a sub-ohm tank. If you are on a pod kit and still chain-vaping, you probably want a higher strength in a 10ml rather than more millilitres.
- 2
Turn the wattage down a notch. Most coils have a range printed on them and most people run at the top of it out of habit. Dropping five or ten watts often costs you very little flavour and cuts consumption noticeably.
- 3
Fill the pod or tank properly. Overfilling floods the coil and leaks straight out of the airflow, and under-priming burns the wick. Both waste liquid. Our guide to filling a pod kit correctly takes two minutes to read.
- 4
Change coils before they die. A tired coil tastes flat, and a flat taste makes you vape more to compensate. Swapping at the first sign of dullness saves liquid as well as your palate.
- 5
Store the bottle properly. Keep it sealed, cool and out of daylight. Heat and light degrade both flavour and nicotine, and a bottle that tastes off gets vaped harder or thrown away. See our notes on e-liquid shelf life and storage.
Most of these overlap with the habits in our round-up of common vaping mistakes beginners make, which is worth a look if you have only recently switched.

Quick answers
How long will a 100ml bottle last?
Between 10 and 30 days for a typical UK vaper. Pod kit users sit at the longer end, sub-ohm tank users at the shorter end. Divide 100 by your daily millilitres for your own figure.
Does a high-powered device use more liquid?
Yes. High wattage produces thicker vapour and a stronger flavour release, and all of that vapour is liquid. A 60W sub-ohm setup can use three times what a low-power pod kit uses.
Is buying a bigger bottle more economical?
Yes, per millilitre. A 100ml shortfill costs less per ml than the same volume bought as 10ml bottles, and that holds after the vape duty because the tax is the same per millilitre in every bottle size.
Does flavour choice affect how much I get through?
It does. Sweet and icy flavours encourage more frequent puffing, so daily consumption creeps up. Plain tobacco and light menthol are generally vaped more sparingly.
Why does a pod system use less liquid?
Pod kits run at low power with higher-resistance coils, which is a far more efficient way to deliver nicotine. They are usually paired with stronger liquid too, so fewer puffs satisfy a craving.
How many puffs is a 100ml bottle?
Very roughly, a 10ml bottle gives around 3,000 puffs on a pod kit, so a 100ml is in the region of 30,000, or 36,000 once you have added two nic shots. It varies hugely with device and puff length. We break the maths down in our guide to how many puffs are in a 10ml nic salt.
