Why Is My Vape Not Producing Enough Vapour? | UK Guide
If you’ve noticed your vape suddenly producing weak vapour, inconsistent clouds, or almost no vapour at all, you’re not alone. This is one of the most common issues vapers experience in the UK and worldwide. The good news is that in most cases, it is not a sign that your device is broken. Instead it usually comes down to a few simple fixable causes.
In this guide we will break down why your vape might not be producing enough vapour, how to diagnose the issue, and what you can do to fix it quickly.
1. Your Coil Is Burnt or Worn Out
One of the most common reasons for low vapour production is a worn-out or burnt coil. The coil is the heating element that vaporises your e-liquid. Over time, it naturally degrades due to heat exposure and residue buildup from e-liquid.
Signs of a worn coil:
- Weak vapour output
- Burnt or dry taste
- Gurgling or inconsistent performance
- Darkened cotton inside the coil
Why it affects vapour:
When the coil struggles to heat properly, it cannot vaporise the liquid efficiently, leading to thin or almost invisible vapour clouds.
Fix:
Replace the coil. Most coils last between 5–14 days depending on usage, e-liquid sweetness, and wattage settings.
2. Low Battery or Power Output
Your vape device relies heavily on battery power to heat the coil. If the battery is low or not delivering enough wattage, vapour production will drop significantly.
Common symptoms:
- Weak vapour despite a new oil
- Slow ramp-up when inhaling
- Device blinking or low battery warnings
Fix:
- Fully charge your device
- Check wattage settings
- Replace old batteries if needed
3. Incorrect Wattage Settings
Using the wrong wattage is another major cause of poor vapour production. Every coil has a recommended wattage range.
Effects:
- Too low: weak vapour
- Too high: burnt taste
Fix:
Check the coil packaging and adjust your device within the recommended range.
4. Not Enough E-Liquid in the Coil (Dry Wick)
If the cotton inside your coil isn’t properly saturated, vapour production will be poor.
Causes:
- Not priming a new coil
- Chain vaping
- Low e-liquid levels
Fix:
- Prime coils before use
- Keep tank filled
- Allow breaks between puffs
5. Airflow Settings Are Too Restricted
Airflow affects how vapour forms and cools.
Signs:
- Tight draw
- Warm vapour
Fix:
Open airflow vents and experiment with settings.
6. E-Liquid Type and VG/PG Ratio
VG produces vapour, while PG enhances flavour.
Fix:
Use higher VG liquids (e.g. 70VG/30PG) for bigger clouds.
7. Coil Flooding
Too much e-liquid can also reduce vapour production.
Fix:
- Remove excess liquid
- Clean tank
8. Device Needs Cleaning
Residue buildup can restrict airflow.
Fix:
- Wash tank with warm water
- Dry thoroughly
9. Wrong Device Type for Your Expectations
Different devices produce different vapour levels.
- Pod systems: small vapour
- MTL tanks: moderate vapour
- Sub-ohm tanks: large clouds
10. E-Liquid Is Too Old or Poor Quality
E-liquid degrades over time and affects vapour production.
Fix:
- Replace old liquid
- Store properly
11. Inhaling Technique Issues
Poor inhaling technique can reduce vapour output.
Fix:
- Take steady draws
- Avoid short puffs
12. Temperature or Environmental Factors
Cold weather can reduce performance.
Fix:
Keep device at room temperature.
13. Faulty Device or Connection Issues
Sometimes hardware faults are the cause.
Fix:
- Check connections
- Try new coil
- Replace device if needed
How to Quickly Diagnose the Problem
- Is the coil new or old?
- Is the battery charged?
- Are wattage settings correct?
- Is the tank full?
- Is airflow open?
- Is e-liquid suitable?
Final Thoughts
Low vapour production is usually caused by simple, fixable issues like coil wear, incorrect settings, or maintenance problems. With proper care and correct setup, most vaping issues can be avoided entirely.
