One of the biggest advertising tools that any disposable vape manufacturer has is a big number on the front of the box – and when it comes to puff counts, the numbers have gotten bigger than ever in 2025. So, how many puffs are in a Lost Mary? In the case of the company’s new MO20000 Pro, the answer to that question is “up to 20,000.”
When talking about disposable vapes, though, the phrase “up to” is very important. A Lost Mary only has a chance to deliver the advertised number of puffs under very specific conditions, and those conditions may not match the way in which you actually vape.
Marketing also comes into play here. Vape manufacturers are very aware of the fact that they can sell more devices if they put bigger numbers on the boxes, so that’s what they do – even if it means that achieving those numbers may not actually be possible in real life. So, how many puffs are really in a Lost Mary vape, and how long will you get to enjoy those delicious Lost Mary flavors? Let’s explore the answers to those questions.
How Many Puffs Is a Lost Mary Advertised to Have?
Let’s begin the guide by establishing a baseline for comparison between the different Lost Mary devices. How many puffs does Lost Mary advertise their devices to have? Here’s an overview of the claimed capacities of several recent Lost Mary vapes.
- Lost Mary MO20000 Pro: Up to 20,000 puffs
- Lost Mary BM16000: Up to 16,000 puffs
- Lost Mary MT15000 Turbo: Up to 15,000 puffs
- Lost Mary BM6000: Up to 6,000 puffs
- Lost Mary MO5000: Up to 5,000 puffs
- Lost Mary OS50000: Up to 5,000 puffs
Along with putting the number of puffs on the front of the box, Lost Mary also makes it easy to tell how many puffs their devices are advertised to have by putting them in the model numbers.
You’re probably getting the idea, though, that actually getting the advertised number of puffs in real life isn’t so easy. Let’s explore why that’s the case.
Will I Actually Get 20,000 Puffs out of a Lost Mary?
So, will you get the advertised number of puffs out of that Lost Mary MO20000 Pro in real life? The unfortunate answer to that question is “probably not” because the advertised puff counts on disposable vapes aren’t actually based on vaping scenarios that usually correspond to real-world usage. In fact, the baseline that manufacturers usually use when deciding the puff counts to advertise is a puff length of just a half second.
Have you ever used a stopwatch to time your average puff length when you use your vape? If you do, you’re probably going to find that your usual puff is much longer than a half second. Let’s do a little quick math with the Lost Mary MO20000 Pro to determine what you can expect with some more realistic puff lengths.
- One second: About 10,000 puffs
- Two seconds: About 5,000 puffs
- Three seconds: About 3,333 puffs
- Four seconds: About 2,500 puffs
As you can see, the actual number of puffs that you’ll get out of a device like the Lost Mary MO20000 Pro will decrease rapidly if you take longer puffs – and almost no one actually puffs on their vape for just a half second at a time. Also, these numbers are only accurate if you believe that the Lost Mary MO20000 Pro is even capable of delivering 20,000 puffs in the first place. That’s definitely questionable because almost every vape manufacturer exaggerates at least a little when advertising the capabilities of their devices.
Why Do Disposable Vape Brands Exaggerate Their Puff Counts?
Does Lost Mary exaggerate the puff counts of their devices? Let’s look at this question in a slightly different way. Reading this article, you’ve learned the advertised puff counts of several recent Lost Mary vapes. Now, let’s look at how much vape juice those same devices contain.
- Lost Mary MO20000 Pro: 18 ml
- Lost Mary BM16000: 25 ml
- Lost Mary MT15000 Turbo: 16 ml
- Lost Mary BM6000: 10 ml
- Lost Mary MO5000: 13.5 ml
- Lost Mary OS50000: 13 ml
As you can see, the e-liquid capacity of a Lost Mary vape doesn’t actually have much of a correlation with its advertised puff count at all. The BM16000 has more e-liquid than the MO20000 Pro, but it’s advertised to deliver fewer puffs. The MO20000 Pro, meanwhile, is advertised to deliver four times as many puffs as the OS5000 while only containing 5 ml more e-liquid.
All vape manufacturers do the same thing because the ultimate goal is to advertise the biggest possible number on the box while staying in roughly the same range as the competition in terms of e-liquid capacities. It’s a bit like the MHz war that took place between computer processor manufacturers in the 1990s and 2000s. The manufacturers knew that people were looking at the numbers, so they prioritized that above efficient design.
The Right Way to Compare Disposable Vape Brands
If you want to compare different brands and models of disposable vapes, the most important thing you can take from this article is that the advertised puff counts don’t really mean much at all. Over the past year or two, the puff counts on disposable vapes have more than doubled without a corresponding increase in e-liquid capacity. With that in mind, the amount of vape juice in the device is the only thing that really matters if you want to compare how long different devices really last.
Count the Days, Not the Puffs
If you really want to know how long a Lost Mary vape lasts, there’s no point in trying to count the number of puffs because you’ll lose track long before the device runs out of e-liquid. Instead, count the number of days that your favorite device typically lasts before you need to replace it. Once you know that, you’ll have a baseline that you can use as a point of comparison with other brands and models.
