Reviewed by VapeSales · Published 2025
Welcome to the VapeSales UK quick-reference FAQ guide — built to answer the most common questions from new and experienced vapers. Whether you’re exploring refillable pod kits, switching from cigarettes, or choosing the right nicotine strength, this guide gives you clear and simple answers.
💨 What Is a Vape?
A vape (or e-cigarette) is a battery-powered device that heats e-liquid into vapour. There’s no burning, no tar, and no ash — making it a popular alternative for adult smokers.
- Disposable vapes (simple, no setup)
- Refillable pod kits (best for beginners)
- Sub-ohm vape kits (big clouds, advanced users)
🌿 Why Switch From Smoking to Vaping?
Cigarettes burn tobacco at high temperatures, producing thousands of chemicals — including tar and carbon monoxide. Vaping is smoke-free and allows you to control your nicotine intake.
- Lower odour & cleaner experience
- No ash or combustion
- More cost-effective long term
- Choose from 100s of flavours
- Nicotine flexibility: 0mg–20mg
🔧 What Is an Atomiser or Coil?
The coil contains cotton and heating wire. It absorbs e-liquid and vaporises it when you inhale.
MTL coils (high resistance 0.8Ω+): tight draw, similar to smoking DTL coils (low resistance below 1.0Ω): warmer vapour, bigger clouds
Pro tip: Always prime your coil before use — this prevents burnt hits and extends coil life.
⚙️ What Is Sub-Ohm Vaping?
Sub-ohm vaping uses coils under 1.0Ω to produce intense flavour and large vapour clouds.
- 50W+ high-power devices
- High-VG e-liquids (70VG+)
- Low nicotine (0–6mg)

🔁 When Should I Replace My Coil?
Most coils last 5–14 days depending on use, sweetness of e-liquid, and wattage.
- Burnt or dry taste
- Reduced vapour
- Gurgling or popping sounds
- Darkened e-liquid
💧 How to Prime a Vape Coil
- Add 2–3 drops of e-liquid onto visible cotton.
- Fill your pod/tank completely.
- Wait 5 minutes.
- Take a few puffs with no firing.
- Start at low wattage.
😮💨 MTL vs DTL Vaping
| Style | How It Works | Best For | Best Juice |
|---|---|---|---|
| MTL | Mouth → lungs | Beginners & ex-smokers | 50/50 or nic salts |
| DTL | Direct inhale | Cloud chasers | High-VG |
🧃 What Is E-Liquid?
- PG: more throat hit, carries flavour
- VG: smoother, denser vapour
- Flavouring: food-grade
- Nicotine: optional
🧮 How to Choose the Right Nicotine Strength
| Your Smoking Habit | Suggested Strength |
|---|---|
| 10+ strong cigarettes/day | 18–20mg nic salts |
| Up to 10/day | 10–12mg |
| Light smoker | 6mg |
| Occasional | 3mg |
| Nicotine-free | 0mg |

| Feature | PG | VG |
|---|---|---|
| Throat Hit | Strong | Smooth |

| Thickness | Thin | Thick |
| Best For | Pods / MTL | Sub-Ohm / DTL |
