A shortfill is a bigger bottle with little or no nicotine and room left for nic shots, while a 10ml bottle is ready to use. Shortfills mean fewer reorders but one extra step, mixing in your shots. A 50ml bottle with one 10ml shot gives about 25 fills of a 2ml pod. Single-use vapes have been banned since 1 June 2025, and you must be 18 or over to buy.
Bigger bottle, one extra step.
If you’re an adult smoker weighing up shortfill e-liquids, the question is usually simple. Is the extra faff worth it? Fair enough. A 10ml bottle is ready to use, and a shortfill needs a little mixing. But it also means fewer reorders, which some people find a relief. It’s a fair thing to wonder about, especially if you’re tired of reordering every few days.
So here’s how the two compare in a normal week. And what it takes to make a shortfill work for you.
This guide is written for adult smokers, nobody else. Which one fits your routine?
What Should You Know About Shortfill E-Liquids Before You Buy?
Start with the rules, because they apply to every brand. Nicotine e-liquid in the UK comes in bottles of 10ml or under, at no more than 20mg/ml. Shortfills get around the bottle limit because they contain little or no nicotine themselves.
Here are the limits worth keeping in your head.
| Rule | Limit |
|---|---|
| Nicotine e-liquid bottle | 10ml or under |
| Nicotine strength | 20mg/ml (2%) maximum |
| Pod or tank size | 2ml or less |
| Single-use vapes | Banned since 1 June 2025 |
| Age to buy | 18 or over |
A flavour name doesn’t change any of this. Read the label for what’s actually in the bottle.
How Do Shortfills Differ From 10ml Bottles?
In size, strength and effort. Here’s the general pattern, though it varies by product.
| Feature | 10ml bottle | Shortfill |
|---|---|---|
| Bottle size | 10ml or under | Larger, often 50ml |
| Nicotine | Already in the bottle | None or low, you add nic shots |
| Extra step | None | Mix in your shots |
| Fills of a 2ml pod | About 5 | Up to about 25 for a full 50ml |
Always check the label for the exact size, the liquid volume and how much room is left for shots. Products vary.
How Does the Maths Work?
Simpler than it looks. Take a 50ml bottle holding 40ml of liquid, which leaves 10ml of space. Nic shots are usually sold in 10ml bottles, commonly at 18mg/ml, though you should check the one you buy.
Add one 10ml shot at 18mg/ml and the whole 50ml ends up at about 3.6mg/ml. That’s 18mg/ml multiplied by 10ml, then divided by 50ml.
Say you fill a 2ml pod once a day. A full 50ml bottle is about 25 fills, so roughly 25 days. Realistically it will vary, because you won’t fill to the line every time. And that’s before you count your own habit.
What Changes Day to Day?
A few things, good and not so good. Here’s the honest list.
- Fewer reorders. One bottle covers weeks, not days.
- An extra step. You have to add the shot and shake it, so allow a couple of minutes.
- A bigger bottle. Easier to knock over, so keep it upright and capped.
- A strength you set. Change the shot, change the strength.
If you hate faff, a 10ml bottle may suit you better. And if you hate running out, a shortfill probably will.
Will It Suit Your Device?
Check the manual. Shortfill liquids are often higher in VG, which can be thicker, and some pod kits suit thinner liquid. Specs vary by model, so the manual is the most reliable guide.
Here’s a quick way to think about it.
- Check what your device suits. The manual or the seller will say.
- Check the VG/PG ratio on the label. Compare it with what your device suits.
- Start with one bottle. Don’t buy several until you know it works.
If it doesn’t suit, you’ll notice it quickly. The liquid may feel thick or the flavour may seem off. Stop and ask the seller.
What Should the Listing Tell You?
Plenty. A good listing answers your questions before you ask them. Here’s what to check.
| On the listing | What to check |
|---|---|
| Bottle size | The size, and how much room is left for shots |
| VG/PG ratio | Stated clearly |
| Nicotine | None or low, with the strength in mg/ml |
| Ingredients | Listed, not left out |
| Seller details | A real UK contact, not just a logo |
When you’re ready to buy vape online, check the age verification at checkout and the delivery terms before you pay. A good shop makes both easy to find.
We won’t quote prices, because they change, so work out the cost per ml from current listings yourself. Keep your order confirmation and the packaging for a few days. And if a price is far below everyone else’s, ask why.
The Vape Gala View
Honestly? Shortfills suit people who don’t mind a minute of mixing, and 10ml bottles suit the rest. Neither is better, and nobody should feel clever or foolish for picking one.
So our advice is boring but it works. Try one bottle of whichever you’re curious about, count your own fills and change one thing at a time. We’d rather you tell us a bottle wasn’t right than hear it ended up in a drawer. It saves you money, and it saves us the returns.
And a plain reminder. The NHS describes vaping as substantially less harmful than smoking for adult smokers who switch. If you don’t smoke, none of this is for you.
Frequently Asked Questions
What is a shortfill e-liquid?
It’s a larger bottle of e-liquid with little or no nicotine and room left for nic shots. You add the shots yourself to reach your strength. Because it contains little or no nicotine, the bottle can be bigger than the 10ml limit for nicotine e-liquid.
How do I add a nic shot to a shortfill?
Open both bottles, pour the shot into the shortfill’s spare space, close the cap and shake gently. Check the label first, because bottle sizes and shot strengths vary. Keep the cap tight afterwards, and store it upright and out of reach of children.
What strength will I get from one nic shot?
It depends on the shot strength and the bottle size. As an example, one 10ml shot at 18mg/ml in a 50ml bottle gives about 3.6mg/ml. Always check your own bottle’s label and do the sum before you mix, as the shot strength and the bottle size both change the result.
Can I use shortfills in a pod kit?
Not always. Many shortfills are higher in VG, which can be thicker, and some pod kits suit thinner liquid. Read your manual, check the VG/PG ratio on the label and ask the seller if it isn’t clear before you fill.
How many fills is a 50ml shortfill?
About 25 fills of a 2ml pod when the bottle is full with the shot added. In practice you won’t always fill to the line, so it varies a little. Count your own fills for a week to plan your next order.
Is it safe to buy vape online in the UK?
Choose a UK retailer that checks you’re 18 or over, shows clear contact details and sells TPD-compliant products. Read the delivery terms and keep your order confirmation, which helps if anything goes wrong. Be wary of prices far below everyone else’s, and compare current listings.
Conclusion
Shortfills trade a little effort for fewer reorders. Check the bottle size and the room for shots, do the strength sum before you mix, and make sure the VG/PG ratio suits your device. If mixing isn’t for you, a 10ml bottle is a perfectly good choice.
Remember the 10ml, 2ml and 20mg/ml limits and store everything out of reach of children. A few minutes of checking can save you a wasted bottle. If you already know what your device suits, now’s a sensible time to browse our range.
