Sub-Ohm Vape Tank FAQs
A sub-ohm tank uses coils below 1.0Ω resistance, typically 0.15-0.5Ω. Lower resistance allows more current flow, creating more heat and vapor. Designed for direct lung inhales with wide airflow. Produces warm, dense clouds with smooth draw. Requires more power (40-100W) and drinks e-liquid faster than MTL tanks.
High VG E-liquids are best. Minimum 70% VG for smooth vapour and proper wicking. 80/20 VG/PG is ideal. Use 3-6mg freebase nicotine maximum - higher creates harsh throat hits with large vapor volume. Shortfills (50ml 0mg + nicotine shot) are economical. Thin liquids (50/50) leak and spit in sub-ohm tanks.
3mg for regular users, 6mg maximum for those needing more. Never use high nicotine salts (10-20mg) - the massive vapour production delivers too much nicotine causing nausea and dizziness. Ex-smokers transitioning to sub-ohm should start at 6mg and reduce as needed.
Generally 1-2 weeks, but sweet e-liquids can kill them in 3-5 days. Clear fruit flavours might give 3 weeks. Higher wattage equals shorter life. Modern mesh coils last 20-30% longer than traditional wire coils. At £3-4 each, budget £8-12 monthly for sub-ohm vape coils.
Voopoo UForce-X Tank (great flavour), FumyTech Dragon Ball (biggest clouds), Vaperz Cloud Shift SubTank (versatility), GeekVape Zeus (reliability). All use mesh coils, have 2ml TPD capacity, and work 60-80W optimally. Coils widely available at £3-4 each.
Not recommended. Nic salts are designed for low-power MTL vaping. Sub-ohm's high vapour volume would deliver excessive nicotine too quickly. The smoothness of salts masks overconsumption until you feel sick. Stick to freebase nicotine for sub-ohm - it's self-limiting through throat hit.
Follow coil recommendations printed on them - typically "Best 65-75W" or similar. Start at the minimum recommended, increase gradually for preference. Too low causes spitting and flooding. Too high burns cotton prematurely. Sweet spot usually 70-80% of maximum rating for flavour and longevity balance.
Not ideal. They require understanding of battery safety, coil priming, wattage adjustment, and proper e-liquid selection. E-liquid consumption is 3-4x higher than MTL. Better suited for vapers who've mastered basics and want more vapour. Start with pod kits, upgrade to sub-ohm later.
Thinner e-liquid (high VG still thinner than 50/50 when heated), larger juice ports for high-power wicking, bigger o-rings with more failure points, and pressure changes from heat. Proper assembly, appropriate e-liquid, and avoiding temperature extremes minimises leaking. Modern designs leak less than older models.
Completely legal, but TPD regulations limit tank capacity to 2ml (reduced from 5ml+ pre-TPD). This means frequent refilling - annoying but legal. The restriction aims to limit nicotine consumption, though it mainly inconveniences users. All legitimate UK retailers only stock TPD-compliant 2ml versions.
MTL Vape Tank FAQs
MTL tanks have restricted airflow (smaller air holes), higher resistance coils (1.0-1.8Ω), and tighter chimney design creating cigarette-like draw. Operate at lower power (10-20W), produce less vapour, and deliver concentrated flavour. Designed for mouth-to-lung inhale technique ex-smokers naturally use.
50/50 PG/VG or 60/40 VG/PG ratios are ideal. Higher PG provides throat hit and thins liquid for small coil ports. Use 10-20mg nicotine salts or 6-18mg freebase. Bar salts (£1.99) perfect - designed specifically for MTL. High VG (70%+) causes dry hits as it can't wick fast enough.
Ex-heavy smokers: 20mg nic salts. Moderate smokers: 10-12mg salts or 12mg freebase. Light smokers: 6-10mg. Social vapers: 3-6mg. MTL's restricted vapour means you need higher nicotine for satisfaction. Better to start high and reduce than struggle with cravings.
Typically 2-3 weeks, sometimes 4 weeks with clear e-liquids. Sweet flavours reduce to 1-2 weeks. Lower power means less stress on coils versus sub-ohm. Nautilus coils famously last 3-4 weeks. At £2-3 each, monthly MTL vape coil cost around £6-8 - very economical.
Aspire Nautilus 3S (legendary reliability), Innokin Zenith 2 (best flavour), Vaporesso xTank T (versatility), Innokin Zlide (simplicity).. All use readily available coils, offer adjustable airflow, and work perfectly 12-18W. Coils available everywhere.
Not recommended. 70% VG or higher is too thick for MTL coil ports, causing dry hits and premature burning. Stick to 50/50 or 60/40 maximum. If you must use high VG, add a few drops of distilled water to thin it, but better to use appropriate liquid.
Generally 10-20W, with 12-15W being the sweet spot for most. Higher resistance coils (1.6Ω+) need less power. Start low and increase gradually. MTL isn't about power - it's about replicating the cigarette experience. Too much power ruins the tight draw and wastes battery.
Yes, significantly. The cigarette-like draw feels familiar, higher nicotine provides proper satisfaction, and modest vapor doesn't overwhelm. NHS stop-smoking services primarily recommend MTL devices. Success rates higher than starting with sub-ohm. You can explore cloud-chasing after successfully switching.
Yes, but modest amounts similar to cigarette smoke. Enough to satisfy the visual aspect of smoking without creating room-filling clouds. Perfect for discrete vaping at work or social situations. Less vapor also means less e-liquid consumption - 10ml lasts 5-7 days typically.
Yes, all legitimate UK-sold MTL tanks are 2ml capacity per TPD regulations. Some have bubble glass options sold separately increasing capacity, technically not illegal to own but shops can't sell them assembled. The 2ml limit is less annoying on MTL tanks due to lower consumption.
