Vape Puff Counts Explained: Why 55,000 Puffs Is 18ml

Packaging shouts 9,000 puffs, 20,000, 55,000 — and usually will not tell you how much e-liquid is inside, which is the number that actually decides how long it lasts. Here is the arithmetic, and why millilitres quietly disappeared from the box.

Why the numbers stopped making sense

Walk into any vape shop and the packaging shouts a puff count: 9,000. 20,000. 40,000. 55,000. What it usually doesn't tell you is how much e-liquid is inside — and that's the number that actually decides how long the thing lasts.

There's a reason millilitres became scarce on packaging. Since 1 June 2023 South Africa has taxed e-liquid by the millilitre, at a rate that has climbed to R3.29/ml. Millilitres went from being a neutral spec to a number with a direct cost attached. Since then, most disposable packaging has stopped printing them, and puff counts have filled the gap — climbing to figures the physics doesn't support.

Worth saying plainly: AirsPops is the one brand in our range that never puts a puff number in the product name. Its packaging leads on millilitres. Every other disposable we stock is named after its puff count — 9k, 20k, 25k, 40k, 55k.

We're not going to tell you which brands to distrust. We'd rather give you the arithmetic, because then you can check any device in any shop, including ours.

The arithmetic

A vape turns liquid into vapour. Every puff consumes a measurable amount — for a normal mouth-to-lung draw, somewhere around 3 to 4 microlitres (thousandths of a millilitre). That's not a marketing figure, it's just what a coil vaporises.

So the honest sum is:

Realistic puffs ≈ millilitres × 1000 ÷ 4
A 15ml device gives roughly 3,750 real puffs. A 3ml one gives about 750.

Turn it around and you get the test that matters. Divide the millilitres by the claimed puffs, and you get microlitres per puff. Anything near 3–4 is plausible. Under 1 is not physically possible at a normal draw.

The same maths across real devices

Every device below is one we stock, so nobody is being singled out. One thing to note about where the numbers come from, because it matters: for the first five, the puff count is part of the product's own name — it's how the brand sells it. For the AirsPops devices there is no manufacturer puff claim at all; AirsPops markets on millilitres. The puff figures in their rows are our own conservative estimates, worked back from capacity, and we've included them here so the comparison is like-for-like.

Device	Claimed puffs	E-liquid	µl per claimed puff
Instabar BE 40k	40,000	25ml	0.62
Nasty Bar Dragon 25k	25,000	22ml	0.88
Elf Bar Raya D3 25k	25,000	21ml	0.84
Nasty Bar XL 20k	20,000	17ml	0.85
Nasty Bar 9k	9,000	13ml	1.44
AirsPops ONE USE XV 15ml	8,500	15ml	1.76
AirsPops XL prefilled pod	5,000	10ml	2.00
AirsPops ONE USE 6ml	1,600	6ml	3.75
AirsPops ONE USE 3ml	800	3ml	3.75

That difference in where the numbers come from is the whole story. The AirsPops rows sit at 1.76–3.75µl per puff because they were derived from how much liquid is actually in the device. The rows above them sit at 0.62–1.44µl because the number is a headline first and a measurement second.

A claim of 0.62µl per puff is asking you to believe a puff uses about a sixth of what a puff actually uses. Our own 3ml estimate of 800 puffs works out at 3.75µl — which is simply what a real draw consumes, because we started from the millilitres rather than from a number that had to look impressive on a shelf.

What this does to a head-to-head

Take a comparison you can make on our own shelf, using figures from both products' own spec sheets: the Nasty Bar 9k against the AirsPops ONE USE XV 15ml.

• On the headline: 9,000 puffs vs our estimate of 4,000. The Nasty looks more than twice the vape.
• On liquid: 13ml vs 15ml. The AirsPops actually holds more.
• In days, for someone getting through about 2ml a day: roughly 6½ days vs 7½. The AirsPops lasts longer.

Read the puff counts and one looks twice the size of the other. Read the millilitres — the number both manufacturers actually measure — and the ranking flips.

The gap widens further up the range. An Instabar BE 40k holds 25ml and claims 40,000 puffs; at a real draw that 25ml gives roughly 6,700. The liquid is genuinely 1.7× the AirsPops XV. The headline says 10×.

A note on what we can and can't show you: some devices in this category no longer publish an e-liquid capacity at all — three of the disposables we stock don't state it anywhere on the packaging or in the supplier spec. Where that is the case we can quote the puff count and nothing else, which is precisely the problem this page is about. Every figure in the table above comes from a published capacity.

The number worth asking for

Millilitres are honest but abstract. What you actually want to know is how long will this last me, so convert once and be done:

Days ≈ millilitres ÷ 2
Two millilitres a day is a fair estimate for a regular daily vaper. Lighter users stretch it further; heavy users won't.

• ONE USE 3ml — about a day and a half. Ideal for testing a flavour.
• ONE USE 6ml — about three days.
• ONE USE XV 15ml — about a week.

It also tells you what's actually cheap

Once you're thinking in millilitres, cost per millilitre follows, and that's where disposables lose badly — you re-buy the battery and the coil along with the liquid every time.

A refillable like the Airscream Pro LITE or Pro II takes 30ml bottles of 313 AirsPops e-liquid — ten times the liquid of a 3ml disposable, in one purchase, with no battery to throw away. Live prices are in the panel below, so you can work out the per-millilitre figure yourself.

Three rules to take shopping

1. Find the millilitres. If the packaging won't tell you, that is itself information.
2. Divide ml by 4 for realistic puffs, or divide ml by 2 for days.
3. Compare cost per millilitre, never cost per claimed puff.

Puff counts aren't regulated or standardised, so there is nothing stopping the number going up next year. Millilitres are measured, declared and taxed — which is exactly why they're the number worth trusting.
