What are SMOK coils + how do they work: complete UK 2026 explainer
Coil construction + components
Coil construction + components + sustained UK consumer awareness + UK TPD compliant. SMOK coils are replaceable atomiser heads: small assemblies that fit inside vape device tanks + pods + sustained UK consumer awareness. Three main components: 1. Heating element (wire or mesh): Kanthal (KA1): most common + iron-chromium-aluminium alloy + standard wattage mode + sustained UK consumer choice. Nichrome (Ni80): nickel-chromium 80/20 alloy + faster ramp-up than Kanthal + sustained UK consumer choice. Stainless steel (SS316): temperature control compatible + sustained UK consumer choice. Mesh sheet: woven metal mesh (Kanthal or stainless steel) + larger heating surface + better flavour + 25-50% longer life vs traditional wire wrap + sustained UK consumer choice. Triple Coil + Quad + Sextuple + Decuple: multiple wires in parallel + maximum vapour for cloud chasing + TFV X4/T6/T10/Q2/Q4 + sustained UK consumer choice. Ceramic: ceramic-based heating element + smoother + slower flavour development + sustained UK consumer choice. 2. Cotton wicking: Organic cotton: typically Japanese organic cotton + neutral flavour + sustained UK consumer awareness. Wicking holes: usually 4 visible holes around coil base + cotton accessible for priming + sustained UK consumer awareness. Cotton purpose: absorbs e-liquid from tank/pod + delivers to heating element + sustained UK consumer awareness. 3. Metal housing: Coil head structure: cylindrical metal housing protects internal components + sustained UK consumer awareness. Threading: screw-in coils thread into tanks + push-fit coils press into pods + sustained UK consumer awareness. Airflow design: holes around housing allow air to mix with vapour + sustained UK consumer awareness. Resistance value printed: ohm value + recommended wattage range + family identifier + sustained UK consumer awareness. Authentication features: scratch-off code on packaging + verifies genuine SMOK + sustained UK consumer protection. Manufacturing: SMOK Technology Co. Ltd manufactures all genuine SMOK coils in PRC + sustained UK consumer awareness. UK Tobacco Products Directive (TPD) compliance: SMOK coils meet UK requirements + UK 18+ age verification + sustained UK consumer protection. UK Trading Standards investigations: counterfeit products + non-compliant products + sustained UK consumer protection. UK consumer rights: faulty coils = retailer replacement obligation under Consumer Rights Act 2015 + sustained UK consumer protection. UK TPD compliant. UK 18+ age verification.
How coils convert e-liquid to vapour
How coils convert e-liquid to vapour + sustained UK consumer awareness + UK TPD compliant. Vaping process step by step: Step 1: e-liquid surrounds coil: tank or pod filled with e-liquid + e-liquid enters coil through wicking holes + sustained UK consumer awareness. Step 2: cotton wicking absorbs e-liquid: capillary action draws e-liquid into cotton + cotton fully saturated when properly primed + sustained UK consumer protection. Step 3: vaper activates device: presses fire button or inhales (autodraw) + sustained UK consumer awareness. Step 4: battery delivers current: lithium-ion battery delivers electrical current at specified wattage + sustained UK consumer awareness. Step 5: current flows through heating element: resistance of coil converts electrical energy to heat + sustained UK consumer awareness. Step 6: heating element rapidly heats up: typically reaches ~200°C+ within milliseconds + mesh coils faster ramp-up + sustained UK consumer awareness. Step 7: heat vaporises e-liquid in cotton: PG/VG/flavouring/nicotine vaporise into aerosol + sustained UK consumer awareness. Step 8: vapour mixes with air: airflow holes draw air through coil + mixing with vapour + sustained UK consumer awareness. Step 9: vapour travels through mouthpiece: vaper draws aerosol into mouth/lungs + sustained UK consumer awareness. Step 10: cotton re-saturates between puffs: e-liquid wicks back into cotton + ready for next puff + sustained UK consumer awareness. Resistance + heat relationship: Lower resistance (sub-ohm): 0.15-0.8Ω + more current = more heat = more vapour + sustained UK consumer awareness. Higher resistance (MTL): 1.0-1.4Ω + less current = less heat = cooler vape + smaller clouds + sustained UK consumer awareness. Wattage role: power input = voltage × current + each coil has recommended wattage range printed (e.g. 25-32W) + always start at lower end + work up gradually + sustained UK consumer protection. What e-liquid contains: PG (propylene glycol) + VG (vegetable glycerin) + nicotine (UK TPD max 20mg/ml) + flavourings + sustained UK consumer awareness. VG/PG ratio affects vaping: high VG (70%+) = thicker vapour + smoother + sub-ohm; 50/50 = thinner + faster wicking + better for MTL + nic salts + sustained UK consumer choice. UK Trading Standards investigations: counterfeit products + non-compliant products + sustained UK consumer protection. UK TPD compliant. UK 18+ age verification.

Why coils are consumable + when to replace
Why coils are consumable + when to replace + sustained UK consumer awareness + UK TPD compliant. Coils are consumable items: cotton burns over time + heating wire degrades + e-liquid residue accumulates + sustained UK consumer awareness; not designed for permanent use. Why cotton degrades: Repeated heating cycles: cotton fibres weaken with each heating cycle + sustained UK consumer awareness. E-liquid residue: sweeteners + flavourings + nicotine residue accumulate on cotton + sustained UK consumer awareness. Caramelisation: sweet e-liquids caramelise on cotton + reduces wicking ability + sustained UK consumer awareness. Eventual cotton burning: when wicking insufficient + cotton burns + irreversible damage + sustained UK consumer protection. Why wire degrades: Repeated thermal cycling: heating + cooling stress weakens wire + sustained UK consumer awareness. Oxidation: surface oxidation reduces conductivity + sustained UK consumer awareness. Hot spot development: uneven heating creates hot spots + sustained UK consumer awareness. Mesh more durable: 25-50% longer life vs wire wrap + sustained UK consumer value. Typical SMOK coil lifespan: Daily vapers (10ml+ per day): 5-7 days typical + sustained UK consumer awareness. Moderate vapers (5-10ml per day): 7-10 days typical + sustained UK consumer awareness. Occasional vapers (under 5ml per day): 1-2 weeks typical + sustained UK consumer awareness. Heavy vapers (15ml+ per day): 3-5 days typical + sustained UK consumer awareness. Mesh coils generally: 25-50% longer life vs regular coils + sustained UK consumer value. When to replace: Burnt taste: most common sign + replace immediately + sustained UK consumer protection. Reduced flavour: muted + dull + sustained UK consumer awareness. Reduced vapour: thinner clouds + sustained UK consumer awareness. Gurgling sounds: flooding + cotton breakdown + sustained UK consumer awareness. Leaking: degraded seals + cotton failure + sustained UK consumer awareness. Dark e-liquid in tank: caramelisation + sustained UK consumer awareness. Spit-back: cotton failure + sustained UK consumer awareness. Cost considerations: Typical SMOK coil pricing: 5-pack typically £9-15 at established UK retailers + sustained UK consumer value. Cost per day: £0.34-0.48 per day for daily vapers + sustained UK consumer value. Compare to disposable vapes: SMOK coils significantly cheaper long-term + sustained UK consumer value. Always buy genuine: counterfeits common + always buy from established UK retailers (UK Companies House + VAT registered + UK Trading Standards monitored) + sustained UK consumer protection. UK 18+ age verification.
