Sub-ohm vaping and MTL vaping differ in coil resistance, draw style and nicotine strength. MTL suits ex-smokers who want a tight, cigarette-like draw, while sub-ohm suits vapers chasing dense clouds and bold flavour.
Choosing between the two shapes every part of your setup: the kit, the coil, the e-liquid ratio and the nicotine you buy. This guide from Royal Vapery breaks down how each style works, what each one costs to run, and which vapers each style fits. Vaping is less harmful than smoking, but not risk-free, according to the NHS, so the right style is the one that keeps you off cigarettes for good.
What is the difference between sub-ohm and MTL vaping?
The main difference between sub-ohm and MTL vaping is coil resistance and inhale style. MTL vaping uses high-resistance coils above 1.0Ω at low wattage for a tight mouth-to-lung draw. Sub-ohm vaping uses low-resistance coils below 1.0Ω at high wattage for a direct-to-lung draw.
That single gap in coil resistance cascades into airflow, vapour output, nicotine strength and e-liquid choice. The table below compares the two styles across the attributes that decide which one you should choose.
| Characteristic | MTL vaping | Sub-ohm vaping |
|---|---|---|
| Coil resistance | 1.0Ω and above | Below 1.0Ω (0.15Ω to 0.8Ω) |
| Wattage range | 8W to 20W | 30W to 100W and above |
| Draw style | Tight, cigarette-like | Airy, direct-to-lung |
| Airflow | Restricted | Open and wide |
| Vapour output | Low to moderate | Large, dense clouds |
| Nicotine strength | 10mg to 20mg (nic salts) | 3mg to 6mg |
| E-liquid ratio | 50/50 PG/VG | 70/30 VG/PG shortfill |
| Best suited to | Ex-smokers, discreet vaping | Flavour and cloud chasers |
What is MTL vaping?
MTL vaping is a mouth-to-lung inhale style where you draw vapour into your mouth first, then breathe it into your lungs. This two-stage draw mirrors a cigarette pull, which is why most ex-smokers start here. MTL devices run high-resistance coils at low wattage through a tight airflow channel.
The tight draw pairs best with 50/50 PG/VG e-liquid and higher-strength nic salts. Thinner 50/50 liquid wicks cleanly through narrow coils, and salt nicotine delivers a smooth 10mg or 20mg hit without harshness. Compact refillable pod kits and closed prefilled pod kits are the two device types that define MTL vaping in the UK.
What are the pros and cons of MTL vaping?
MTL vaping offers a familiar transition for smokers at low running cost, though it trades away cloud size. The key benefits and drawbacks include:
- Natural for ex-smokers: the tight draw and throat feel replicate a cigarette closely.
- Efficient nicotine delivery: higher salt strengths satisfy cravings on less e-liquid.
- Longer battery life: low wattage between 8W and 20W drains cells slowly.
- Discreet vapour: modest clouds suit workplaces and public spaces.
- Fewer clouds: cloud chasers find the vapour output underwhelming.
- Tighter draw: vapers used to open airflow can find MTL restrictive.
What is sub-ohm vaping?
Sub-ohm vaping is a direct-to-lung inhale style using coils rated below 1.0 ohm. Low resistance draws more power, heats e-liquid faster and produces large vapour clouds with intense flavour. Sub-ohm devices run high wattage through wide, open airflow, so vapour goes straight to the lungs like a deep breath.
The high output pairs best with high-VG shortfill e-liquid at 70/30 VG/PG and lower nicotine of 3mg to 6mg. Thicker liquid protects the coil from dry hits at high wattage, and low nicotine keeps a big lung inhale smooth. Powerful sub-ohm kits carry larger batteries and adjustable wattage to match. Royal Vapery stocks sub-ohm kits from Vaporesso, VooPoo and Geekvape in the full wattage range.
What are the pros and cons of sub-ohm vaping?
Sub-ohm vaping delivers the biggest clouds and boldest flavour, though it costs more to run. The key benefits and drawbacks include:
- Dense vapour: high wattage produces thick clouds and vivid taste.
- Bold flavour: wide airflow carries layered fruit, dessert and menthol notes.
- Adjustable power: variable wattage tunes the vape to your preference.
- Smooth low-nicotine hits: 3mg to 6mg stays gentle on a lung inhale.
- Higher e-liquid use: more vapour burns through shortfill faster.
- Faster battery drain: high wattage means more frequent charging.
Which nicotine strength suits each style?
Nicotine strength splits sharply between the two styles. MTL vaping uses 10mg to 20mg nic salts, while sub-ohm vaping uses 3mg to 6mg freebase e-liquid. A big sub-ohm draw multiplies vapour volume, so a lower strength still delivers plenty of nicotine.
UK law caps nicotine-containing e-liquid at 20mg/ml, bottles at 10ml and tanks at 2ml under the Tobacco and Related Products Regulations, per GOV.UK. Vaping a 20mg salt through a sub-ohm coil would feel overwhelming, and a 3mg shortfill through an MTL pod would leave cravings unmet. Match the strength to the draw, not the other way round.
Which vaping style should you choose?
It depends on your history with cigarettes, your priorities and where you vape. Use these scenarios to decide:
- Recent switch from smoking: choose MTL for the cigarette-like draw and higher nicotine that curbs cravings.
- Clouds and flavour: choose sub-ohm for dense vapour and intense taste from high-VG shortfill.
- Compact and discreet: choose MTL pod kits for small size, quiet output and pocket portability.
- Lowest running cost: choose MTL for slower e-liquid use, cheaper kits and longer battery life.
- Adjustable, advanced setup: choose sub-ohm for variable wattage, airflow control and swappable coils.
Beginners moving off cigarettes gain the most from an MTL setup. Starter vape kits pair a simple pod device with 50/50 nic salts, so the switch feels familiar from the first draw.
What are the best MTL prefilled pod kits?
Prefilled pod kits deliver MTL vaping with zero refilling. Each pod arrives filled with nic salt e-liquid, clicks into the battery and lasts thousands of puffs before you swap it. These kits replaced single-use disposables, banned across the UK from 1 June 2025, with a rechargeable, TPD-compliant format.

Can you switch between sub-ohm and MTL vaping?
Yes, many modern pod kits switch between sub-ohm and MTL vaping through swappable coils and adjustable airflow. A crossover kit accepts both a high-resistance MTL coil and a low-resistance sub-ohm coil, so one device covers both styles. Close the airflow and fit an MTL coil for a tight draw, or open it and fit a sub-ohm coil for clouds.
Switching styles means switching e-liquid too. Move to 50/50 nic salts for an MTL draw, and drop to 3mg to 6mg 70/30 shortfill for a sub-ohm draw. Crossover kits suit vapers who want a discreet MTL vape at work and bigger clouds at home without buying two devices.

Frequently asked questions
MTL is better for beginners, especially ex-smokers. The tight, cigarette-like draw feels familiar, the higher nicotine satisfies cravings, and the compact pod kits are simple to use. Sub-ohm suits vapers who already understand wattage, airflow and coil resistance, so most people start with an MTL setup.
No, sub-ohm vaping is not stronger in nicotine, but it feels bigger. Sub-ohm uses lower strengths of 3mg to 6mg, while MTL uses 10mg to 20mg nic salts. The larger vapour volume in sub-ohm delivers plenty of nicotine at a lower strength, which is why the numbers look reversed.
You can use low-strength nic salts in a sub-ohm kit, but high strengths feel harsh. A sub-ohm coil produces a large draw, so 20mg salt would overwhelm the throat. Stick to 3mg to 6mg for sub-ohm and save 10mg to 20mg nic salts for tight MTL pod kits.
Shortfill e-liquid works poorly in an MTL pod kit. Shortfills use a thick 70/30 VG/PG ratio that struggles to wick through narrow MTL coils, which causes dry hits. MTL pods perform best with thinner 50/50 e-liquid or nic salts designed for high-resistance coils and low wattage.
Sub-ohm vaping uses more e-liquid than MTL. High wattage and wide airflow vaporise liquid quickly, so a sub-ohm setup can empty a tank in a day. MTL vaping sips e-liquid slowly at low wattage, which makes it the more economical style for daily use across a week.
Sub-ohm vaping drains the battery faster. Running coils at 30W to 100W pulls far more current than an MTL device at 8W to 20W. Sub-ohm kits carry larger or dual batteries to compensate, while MTL pod kits last longer between charges thanks to their low power draw.
Flavour depends on the setup, so neither style wins outright. Sub-ohm vaping produces bigger vapour that carries bold, layered flavour notes. MTL vaping concentrates flavour through a tighter draw, which many vapers find more focused. The coil, e-liquid and airflow matter more than the style itself.
No evidence shows sub-ohm vaping is more harmful than MTL when you use compliant devices and e-liquids. Both styles rely on TPD-compliant kits, quality batteries and correct wattage ranges. Buy reputable products and follow proper battery safety guidance for a satisfying vape with either style.
Sub-ohm coil resistance is below 1.0 ohm, commonly between 0.15Ω and 0.8Ω. The low resistance draws more power, heats e-liquid quickly and produces large clouds. Coils in this range need higher wattage and high-VG shortfill to run cleanly without dry hits or a burnt taste.
MTL coil resistance is 1.0 ohm and above, often between 1.0Ω and 1.8Ω. The higher resistance runs at low wattage of 8W to 20W and produces a tight, flavourful draw. These coils suit 50/50 e-liquid and nic salts for a cigarette-like mouth-to-lung vape.
MTL vaping is cheaper to run. It uses less e-liquid, cheaper kits and lower-wattage batteries that last longer per charge. Sub-ohm adds cost through frequent coil changes and higher e-liquid consumption. From 1 October 2026, Vaping Products Duty adds £2.20 per 10ml of e-liquid, per GOV.UK.
Yes, sub-ohm kits are legal in the UK when they meet TPD and TRPR rules. Tanks are capped at 2ml, nicotine e-liquid at 10ml bottles, and strength at 20mg/ml, per GOV.UK. The 2ml tank limit means sub-ohm vapers refill more often than the hardware could otherwise allow.
Yes, many crossover pod kits do both sub-ohm and MTL through swappable coils and adjustable airflow. Fit a high-resistance coil and close the airflow for MTL, or fit a sub-ohm coil and open it for clouds. Switch the e-liquid to match, moving between 50/50 salts and 70/30 shortfill.
Yes, MTL is closer to smoking than sub-ohm. The mouth-to-lung draw, tight airflow and throat feel replicate a cigarette pull, which helps recent switchers adjust. Sub-ohm uses a deep, open lung inhale that feels nothing like a cigarette, so ex-smokers usually prefer MTL first.
Use 3mg to 6mg nicotine for sub-ohm vaping. The large vapour volume delivers nicotine efficiently, so a low strength stays smooth on a lung inhale. Higher strengths like 12mg or 20mg feel harsh through a sub-ohm coil. Save those strengths for tight MTL pod kits instead.
