The number in the name is a manufacturer figure, measured under steady conditions. In daily use you rarely hit it exactly, because your draw length and draw strength differ. So what matters is not the number on the box but your own use. Divide the puff count by your puffs per day and you have your runtime. 12,000 puffs at 300 puffs a day is around 40 days. The math works the same for every Tornado vape, from the Digital Box 12000 to the Eco 4in1 80000.
What does the number in a vape's name mean?
It states how many puffs the device delivers when every puff is the same. The measurement uses a steady draw length and a steady pause between draws. So the number describes the device's capacity, not your day. At RandM and Fumot it sits right in the product name, from 12,000 on the Digital Box to 80,000 on the Eco 4in1.
Two devices with the same number will still last you different lengths of time, because your draw habits decide it. Which ranges exist and how else they differ is under Disposable Vapes.
Why do you never land exactly on the stated number?
Because everyone draws differently. A long, hard draw uses more e-liquid than a short one. Draw in a row and you give the coil no pause, so the device pulls more power. Then there is the environment: cold wears on the battery, heat on the e-liquid. For almost everyone the result is a number below the figure on the box.
- Draw length. Two seconds or four seconds adds up to a noticeable difference over a day.
- Draw strength. The harder you draw, the more e-liquid gets vaporized.
- Pauses. Many puffs back to back heat the coil up more.
- Temperature. In the cold the battery delivers less, and in a hot car in summer the e-liquid suffers.
How do you work out your own runtime?
You need two numbers: the puff count of your model and your puffs per day. The puff count is in the product name. You probably do not know your puffs per day exactly, and you do not need to count them. Use your last device as the yardstick instead and divide its puff count by the number of days it lasted you.
- Take the model's puff count, say 25,000.
- Divide by your puffs per day, say 300.
- The result is days, here around 83.
Then run it the other way if you have a target. If a device should last two months and you take 300 puffs a day, you need around 18,000 puffs. That puts you at the Fumot Tornado 20000 or above.
How do the models compare on runtime?
It comes down entirely to your puffs per day. The table runs every model through three typical levels of use: 150 puffs a day for occasional vaping, 300 for the normal case, 500 for heavy use. All the figures start from the manufacturer number and are rounded. Your actual figure will usually sit a little below.
| Model | Puffs per manufacturer | 150 puffs a day | 300 puffs a day | 500 puffs a day |
|---|---|---|---|---|
| Fumot Digital Box 12000 | 12,000 | 80 days | 40 days | 24 days |
| RandM Tornado 15000 | 15,000 | 100 days | 50 days | 30 days |
| Fumot Tornado 20000 | 20,000 | about 130 days | about 65 days | 40 days |
| RandM Tornado 25000 | 25,000 | about 165 days | about 83 days | 50 days |
| Fumot Tornado 35K | 35,000 | about 235 days | about 115 days | 70 days |
| Fumot Leopard 40K | 40,000 | about 265 days | about 135 days | 80 days |
| Fumot Eco 2in1 50000 | 50,000 | about 330 days | about 165 days | 100 days |
| Fumot Eco 4in1 80000 | 80,000 | about 530 days | about 265 days | 160 days |
Which disposable vape lasts longest?
The Fumot Eco 4in1 80000. At 80,000 puffs it sits at the top of the range and replaces nearly seven 12,000 puff devices on paper. Behind it come the Eco 2in1 at 50,000 and the Leopard 40K at 40,000 puffs. Both Eco models also hold several flavors in one device that you can switch between.
At runtimes like that the battery counts too. The big models recharge over USB-C so the power does not run out before the e-liquid does. How to handle the battery is on our Battery Safety page.
When is a high puff count not worth it?
When you like switching flavors. At 300 puffs a day, an 80,000 puff device ties you to your choice for around nine months. If you want something new after two weeks, you are better off with 12,000 or 15,000 puffs and trying a different direction more often.
Work out the price per puff too, not the price per device. Divide the price by the puff count and the models become comparable. And if you are unsure about the flavor, start small and find your direction among the fruity vapes or the icy vapes.
FAQ
Does the display count the puffs?
No, none of the devices has a puff counter. You estimate your number from the last device: puff count divided by the days it lasted. What the display shows instead is in our article on what the display on a vape shows.
What happens if the battery runs out before the e-liquid?
All our models charge over USB-C: you simply recharge and keep vaping until the e-liquid is used up. That is exactly what the port is for. Devices without a charging port are done as soon as the battery is.
Why is my vape empty sooner than my friend's?
Because you draw differently. Draw length and draw strength are the two biggest levers. Draw hard for four seconds and you use noticeably more e-liquid per puff than someone taking a short draw, even though both boxes show the same number.
Is a higher puff count automatically cheaper?
Usually, but not always. Divide the price by the puff count and you see the price per puff, which lets you compare models directly. What you have to weigh against it is whether you want to stay with one flavor that long.
Can I check the puff count myself?
Not exactly, that would take measuring equipment. What you can check is whether the device is genuine, because the figure only means anything on an original. The security code is on the packaging, and the steps are in the Authenticity Check.
