How to choose the right device and e-liquid

Choosing well saves money, frustration and the waste of buying gear that does not fit your style. Here is the breakdown that fits most UK adult vapers.

Step 1: pick your device category

Three main categories cover most UK adult vapers. Refillable pod kits are low-power compact devices with a refillable pod containing a replaceable or built-in coil. They suit beginners, ex-smokers transitioning from cigarettes and anyone wanting discretion and long battery life. The MTL (mouth-to-lung) draw mimics a cigarette. Examples: Vaporesso XROS, OXVA Xlim, Aspire Cyber. Sub-ohm mods are high-power devices with sub-1 ohm coils that vapourise large amounts of e-liquid per puff. They suit experienced vapers who want big clouds and intense flavour, and freebase e-liquid in a 70/30 VG ratio. Examples: Voopoo Drag, GeekVape Aegis, SMOK Mag. Prefilled pod systems are simpler closed-pod kits where the pod comes pre-loaded with e-liquid. They replaced disposables after the UK single-use ban on 1 June 2025. Examples: Lost Mary BM6000, ELFBAR pods, SKE Crystal Plus.

Step 2: match nicotine to your habit

UK TPD-compliant e-liquid is sold at 0 mg, 3 mg, 6 mg, 10 mg, 12 mg, 18 mg and 20 mg per millilitre. The 20 mg/ml maximum is the UK legal limit. Match starting strength to your current cigarette habit. Heavy smokers (20+ cigarettes per day) typically start at 20 mg nic salt in a pod kit. Moderate smokers (10-20 per day) usually do well at 10 or 12 mg. Light or social smokers fit at 6 mg or below. Sub-ohm vapers typically use 3 mg or 6 mg freebase because the high power amplifies the throat hit. Step down gradually over months as your body adapts. Many UK vapers reach 0 mg within 12-18 months and continue vaping for the habit and flavour rather than nicotine.

Step 3: nic salt vs freebase

Two different forms of nicotine for different devices. Nic salt e-liquid uses nicotine bonded with benzoic acid, which makes it smoother on the throat at higher concentrations. Nic salts are formulated for low-power pod kits at 10 or 20 mg strength. The smooth delivery makes 20 mg salts comparable to a strong cigarette without harshness. Freebase nicotine is the traditional form. It is harsher on the throat at high concentrations so freebase e-liquid is typically sold at 3, 6 or 12 mg for use in sub-ohm devices that vapourise more liquid per puff. Simple rule: nic salts for pod kits, freebase for sub-ohm. Mixing them up gives a poor experience: salts in a sub-ohm tank can give nicotine overdose symptoms; freebase 3 mg in a pod kit gives almost no nicotine hit.

Step 4: PG VG ratio

Two main ratios cover almost every UK e-liquid. 50/50 PG/VG is the standard for nic salt e-liquid and pod kits. Higher PG (propylene glycol) gives stronger throat hit, better flavour and thinner consistency that wicks well in small pod coils. 70/30 VG/PG is the standard for sub-ohm freebase e-liquid and high-power devices. Higher VG (vegetable glycerine) gives bigger denser clouds, smoother throat hit and works better with the larger coil openings on sub-ohm tanks. Some shortfill e-liquids go even higher to 80/20 or 100% VG for maximum cloud production. The wrong ratio in a device wicks badly: 70/30 in a small pod coil leaks or burns, 50/50 in a sub-ohm tank gives weak clouds and harsh throat hit.

Step 5: pick a flavour profile

Five flavour categories cover most UK vape preferences. Tobacco (classic, RY4, virginia, menthol tobacco) is best for ex-smokers in the first 1-3 months because the familiar taste makes the transition easier. Menthol and ice (cool blue, ice mint, polar mint) suits ex-cigarette smokers who used menthol cigarettes and anyone wanting a clean palate-cleansing flavour. Fruit (strawberry, mango, blueberry, watermelon) is the most popular adult vape category and dominates UK pod sales. Dessert and bakery (custard, vanilla, jam doughnut) appeals to longer-term vapers wanting a sweeter complex flavour but clogs coils faster. Drinks (cola, energy drink, coffee) is a smaller category but with strong fans. Most UK vape kits ship with a basic starter pod or small bottle. After that, buying 10 ml bottles in 2-3 different flavours per category lets you find your preferred profile without wasting money.

Step 6: replace coils and pods on time

Coils and prefilled pods typically last 5 to 14 days for an average UK vaper, depending on device, e-liquid and how heavily you vape. Replaceable coils in pod kits and sub-ohm tanks last 7 to 10 days for moderate use (around one tank-fill per day) and 3 to 5 days for heavy use. Prefilled pods last as long as the e-liquid lasts because the coil is matched to the volume. Signs you need to replace: burnt taste, reduced flavour, gurgling, leaking, dark or discoloured coil window. Priming new coils properly (drip e-liquid into the coil head and wait 5-10 minutes before first use) doubles their typical lifespan. Sweet dessert e-liquids clog coils faster than menthol or simple fruit flavours.
