How many puffs in a Geek Bar? And Elf Bar, Vuse, Breeze Pro

By Antonio Cappiello · Last reviewed 2026-09-25

The Geek Bars in a 2025 UC Davis lab study were rated at 15,000 puffs, Flum Pebble and Esco Bars 6000 at 6,000, Elf Bar at 5,000 and Esco Bars 2500 at 2,500. Those are machine-puff ratings, not your puffs, and the same study found every Geek Bar it tested held about half its labelled nicotine.

Rated puff counts, by device

These are the devices people ask about by name. Every rating in this table comes from one peer-reviewed source: a 2025 study by Nicholas Robertson, Haylee Hunsaker, Megan Yamamoto, Kaitlyn Cheung, Brett Poulin and Tran Nguyen at the University of California, Davis, published in ACS Omega. They bought 25 devices across four brands and tested what was actually in them.

Device	Rated puffs	Nicotine on the label	Nicotine measured
Geek Bar	15,000	50 mg/ml	21.5 to 36.0 mg/ml
Flum Pebble	6,000	50 mg/ml	16.2 to 59.4 mg/ml
Esco Bars 6000	6,000	30 to 50 mg/ml	16.0 to 64.9 mg/ml
Elf Bar	5,000	40 to 50 mg/ml	31.2 to 53.6 mg/ml
Esco Bars 2500	2,500	50 mg/ml	25.0 to 61.2 mg/ml
JUULpod (0.7 ml)	about 200	59 mg/ml US	measured separately, see below

Ratings differ by model within the same brand, and they change between production runs and between countries. The number on your box is the number to go by, and the table is here to show the scale, not to stand in for the label you can read yourself.

Two devices the lab did not test

People ask about these two as often as the rest, so they are here with their sources spelled out. The figures below are weaker evidence than the table above, and you should treat them that way.

Device	Rated puffs	Liquid	Nicotine	Where the figure comes from
Vuse Alto pod	Vuse publishes none	1.8 ml	5 percent	Volume and strength from the California Department of Justice Unflavored Tobacco List, a state government register. Retailers estimate 200 to 300 puffs; that estimate is theirs, not Vuse’s and not a measurement.
Breeze Pro	2,000	6 ml	5 percent, 50 mg/ml	Retailer product listings only. No regulator or laboratory source, and no peer-reviewed test of this device that we could find.

The Vuse entry is worth a second look. It is one of the few e-cigarettes with FDA marketing authorisation, and its maker does not advertise a puff count at all. The devices at the top of this page, none of which are authorised, lead with 15,000.

That is not a coincidence. A puff count is a marketing number, and the products competing on it are the ones competing hardest for attention.

What the lab found inside them

This is the part the box does not tell you, and it is the reason this page exists.

Across the 25 devices, 10 of them, 40 percent, held significantly less nicotine than the label claimed. Twelve matched their labelled concentration. The Geek Bar result was the most consistent in the study: every Geek Bar tested came in at roughly half its labelled nicotine content, measuring 21.5 to 36.0 mg/ml against a 50 mg/ml label.

Read that carefully, because it cuts both ways. A device holding less nicotine than it claims is not a safer device, and it is not a reason to relax. It means the number printed on your device is not a reliable basis for working out your dose, in either direction: some units in the same study measured well above their label, up to 64.9 mg/ml against a 30 to 50 mg/ml claim.

Credit where it is due: nobody selling these devices published that. A university lab bought them at retail and measured them.

Why you never get the rated number of puffs

A rated puff count is produced by a machine, not a person.

The UC Davis tests used a 3-second puff of 80 ml, taken every 27 seconds. That is the standard way to test, and it is nothing like how a device gets used in a pocket over a day.

A study of 58 UK vapers that recorded 200,411 real puffs over two months measured a mean puff of 3.4 seconds, with individual averages ranging from 0.9 seconds to 6.9 seconds. Someone at the top of that range takes roughly seven times as much liquid per puff as someone at the bottom. Two people with the same device and the same rated count will empty it weeks apart.

So the rating is closer to a manufacturer’s fuel economy figure than to a measurement. It is achievable under test conditions and it tells you very little about your week.

Why the numbers on the box got so large

They grew fast, and recently.

A 2026 study of US online vape stores tracked disposable listings between 2022 and 2024. The average listing went from 3,265 puffs and 8.75 ml of liquid in 2022 to 13,980 puffs and 17.88 ml in 2024. The largest listings claimed up to 40,000 puffs and up to 230 ml.

In the UK the law went the other way. A vape may hold no more than 2 ml of liquid at no more than 20 mg/ml of nicotine, which trading standards treat as about 600 puffs, and single-use vapes have been banned outright since 1 June 2025.

The same product category, in other words, is sold as a 600-puff device in one country and a 40,000-puff device in another.

Which of these are actually authorised

Worth knowing, because it is rarely mentioned next to the puff count.

In the United States, every new tobacco product needs FDA marketing authorisation before it can legally be sold. The FDA has authorised a short list, which includes the Vuse Alto power unit with tobacco-flavoured pods (18 July 2024), NJOY DAILY and NJOY ACE menthol products (21 June 2024), and the JUUL device with Virginia tobacco and menthol pods (17 July 2025).

The high-count disposables in the table above are not on that list. The FDA has issued warning letters to retailers selling unauthorised products, naming Geek Bar and Elf Bar products among them.

Two things that authorisation does not mean. It does not mean a product is safe: the FDA’s own standard is a public health standard, not a safety finding, and the CDC states plainly that no tobacco product, including e-cigarettes, is safe. And an unauthorised product is not necessarily more harmful than an authorised one; it means the maker has not put it through the review.

The only count that is actually yours

Every number on this page belongs to a machine, a lab or a listing. None of them is your number.

Your number depends on how long you draw, how often you reach for it, and how the day is going. Recorded daily use in a 24-hour study averaged 225 puffs, with individuals ranging from 24 to more than 1,000. That range is the whole point: the average tells you nothing about you.

Puff Counter counts each puff with one tap, shows the day’s total and the hourly pattern, and estimates the nicotine from the strength and puff volume you set. Counting is free, with no account and no ads.

Questions people also ask

How many puffs are in a Geek Bar?

The Geek Bar units tested in a 2025 UC Davis lab study were rated at 15,000 puffs. That is a machine-puff rating, taken with 3-second puffs 27 seconds apart, so it is not a count of your puffs. Rated counts also differ by model, and the same brand sells devices rated well above and below that figure.

How many puffs are in a Geek Bar Pulse?

Geek Bar rates its models separately and the number on the box is a machine-puff claim rather than a measurement of use. The only figure independently tested in a peer-reviewed study is the 15,000-puff rating on the Geek Bar devices in the 2025 UC Davis work. Check the box for the specific model you have, and treat it the way you would treat a range figure on a car.

How many puffs are in an Elf Bar?

The Elf Bar devices in the 2025 UC Davis study were rated at 5,000 puffs, with labelled nicotine of 40 to 50 mg/ml and measured nicotine of 31.2 to 53.6 mg/ml. In the UK a legal vape holds no more than 2 ml, which trading standards treat as about 600 puffs, and single-use vapes have been banned there since 1 June 2025.

How many puffs are in a Juul pod?

About 200. A 2022 lab study in Tobacco Control measured a 0.7 ml JUULpod using 4.4 mg of liquid per 3-second puff, which works out at roughly 200 machine puffs. The JUUL device with Virginia tobacco and menthol pods was authorised by the FDA on 17 July 2025.

Which vape has the most puffs?

The largest US online listings in a 2026 study of the 2022 to 2024 market claimed up to 40,000 puffs and up to 230 ml of liquid. No brand is named here because the number is a machine-puff claim rather than a measure of use, and the devices carrying the biggest claims are generally the ones with no FDA marketing authorisation. Your vape will also run out before its rated count, because the rating assumes a 3-second machine puff and real puffs average 3.4 seconds with individuals ranging from 0.9 to 6.9.
