Why Do Other People’s Vapes Produce So Much Vapor?

If you’ve ever seen someone take a puff from their vape and produce a massive cloud—much thicker and denser than yours—you’re not alone. Many vapers wonder why some devices generate huge vapor while theirs seems lighter, thinner, or less impressive. Vapor production is influenced by several factors: the type of device, coil design, airflow, e-liquid composition, wattage output, and even the user’s inhaling technique. Understanding these differences can help you figure out whether your vape is performing normally or if there’s room for improvement. Below is a comprehensive explanation of the key reasons why other people’s vapes produce so much vapor.

1. The Type of Device Makes the Biggest Difference

Not all vapes are built for cloud production. In fact, devices fall into two major categories:

Mouth-to-Lung (MTL) Devices

These include small disposables, pod systems, and compact vapes. Their characteristics:

• Low vapor output

• Tight airflow similar to smoking

• Lower wattage

• High nicotine satisfaction

If you’re using a simple disposable or a pod-style vape, it’s not designed to create massive clouds. These devices prioritize convenience, flavor, and nicotine delivery rather than extreme vapor.

Direct-to-Lung (DTL) / Sub-Ohm Devices

These are the ones used by people who blow huge clouds. They feature:

• Powerful batteries

• High wattage (40W–200W)

• Large mesh coils

• Wide airflow

• Low nicotine e-liquid

These devices vaporize significantly more liquid per puff, resulting in thick, dense clouds. If someone is producing huge vapor, they’re likely using a sub-ohm tank, box mod, or high-power disposable.

2. Coil Type and Resistance Levels Affect Vapor Output

Coils play a huge role in vapor production. Sub-ohm devices use coils with resistance below 1.0Ω—usually around 0.15–0.6Ω. Lower resistance coils heat faster, absorb more e-liquid, and vaporize larger amounts per puff.

Key differences:

Mesh coils have become the standard for big vapor devices because:

• They heat evenly

• They create more surface area

• They vaporize more e-liquid

• They remain stable at high wattage

So when you see gigantic clouds, there’s a good chance the device is using large mesh coils designed specifically for vapor volume.

3. Airflow Plays a Major Role in Cloud Production

Airflow design changes everything. Big-cloud devices typically have:

• Wide open airflow

• Multiple airflow slots

• Adjustable airflow rings

• Direct-to-lung inhalation design

More airflow allows more vapor to form and creates a smoother inhale at high wattages.

If your vape has:

• Small airflow holes

• No adjustable airflow

• A tight draw

…it will naturally produce less vapor.

Open airflow = Big clouds
Tight airflow = Small, cigarette-like clouds

4. Higher Wattage = More Vapor

Wattage determines how quickly the coil heats up and how much e-liquid it can vaporize at once.

Low-power devices:

• 5W–15W

• Gentle vapor

• Intended for nicotine efficiency

High-power devices:

• 40W–200W

• Massive vapor

• Require low-nicotine liquid

Many large-cloud users vape at 60–100W or even higher, while small disposables usually run at 8–12W. That massive wattage difference directly affects the size of the cloud.

5. The E-Liquid Used Makes a Huge Difference

Not all vape juice is the same. The two main ingredients that affect cloud size are:

VG (Vegetable Glycerin)

• Thick

• Creates dense vapor

• Smooth inhale

• Ideal for cloud chasing

• Common in sub-ohm liquids (70% VG or higher)

PG (Propylene Glycol)

• Thinner

• Strong throat hit

• Better flavor delivery

• Less vapor production

When someone is blowing huge clouds, they are most likely using high-VG e-liquid.

By contrast, many disposables use:

• 50/50 VG/PG

• Or 60/40 ratios

• Designed for smooth nicotine, not cloud production

If your vape uses a balanced or PG-heavy blend, you will naturally get less vapor.

6. Nicotine Strength Influences Vapor Size

Low nicotine = high vapor
High nicotine = low vapor

Cloud-chasing setups use very low nicotine, often:

• 0mg

• 3mg

• 6mg

This allows users to take large, deep inhales without harshness.

Small vapes and disposables use:

• 20mg (UK/EU)

• 30–50mg (US and other regions)

High nicotine liquids cannot be inhaled deeply, so devices are designed to produce less vapor per puff to prevent discomfort.

---

7. User Technique Also Impacts Vapor Production

Even with the same device, inhaling technique matters.

People who produce large clouds typically:

• Inhale directly into their lungs

• Take long, deep draws (3–5 seconds)

• Exhale slowly for maximum density

• Use open airflow settings

MTL users usually:

• Take quick, gentle puffs

• Hold vapor in the mouth first

• Produce significantly smaller clouds

Technique alone can easily triple or quadruple the amount of visible vapor.

8. Newer Devices Are Simply More Powerful

High-performance disposables today—20,000 puffs, 30,000 puffs, 40,000 puffs—use:

• Dual mesh coils

• Turbo airflow systems

• Intelligent chipsets

• High wattage output

• Large batteries

Someone using a high-end model like a 40,000-puff device with a screen will naturally produce much more vapor than someone using an older or smaller vape.

Technology evolves quickly, and modern devices are optimized for vapor density, smoothness, and heat efficiency.

---

9. Environmental Conditions Also Affect Cloud Size

Even the weather can change vapor visibility:

• Cold air makes vapor appear thicker

• Humid air makes clouds linger longer

• Hot, dry air reduces cloud density

• Indoor environments amplify cloud size

So part of the “why is their vapor so big?” effect might simply be the surroundings.

Final Thoughts: Why Other People’s Vapes Produce More Vapor

Other people’s vapes produce more vapor mainly because of:

• The type of device (DTL vs. MTL)

• High-wattage power output

• Sub-ohm or mesh coils

• Wide airflow

• High-VG e-liquid

• Low nicotine strength

• Advanced technology

• Deep inhaling technique

If your vape produces less vapor, it may be functioning exactly as designed—many devices are optimized for smooth nicotine delivery, portability, and flavor rather than cloud production.
