If you've stood in a vape shop and felt like everyone's speaking a different language — pods, coils, sub-ohm, mesh, nic salts, PG, VG — this guide is for you. We'll cut through the jargon, explain what each thing actually does, and tell you which combination is right for you.

First, What's the Difference?

Pod kits

Small, light, pen- or pebble-shaped devices. The pod is a small plastic chamber that holds your e-liquid and has a coil built in. Pods either come pre-filled (sealed by the manufacturer) or refillable (you top them up with bottled e-liquid). When the coil dies, you replace the whole pod — or, on some kits, just the coil insert.

Coil resistance: usually 0.6–1.2 Ω

Wattage: 10–20W (no manual adjustment needed)

E-liquid: 50/50 nic salts at 10mg or 20mg

Sub-ohm coil tanks

Bigger, button-fired devices (often called "box mods"). The tank is a glass chamber with a screw-in replaceable coil that sits below 1.0 Ω (hence "sub-ohm"). High wattage = lots of vapour = big clouds.

Coil resistance: 0.15–0.8 Ω

Wattage: 30–80W+ (manually adjusted)

E-liquid: high-VG (70/30 or higher) freebase, usually 3mg or 6mg

Which Is Better for You?

Choose a pod kit if you...

• Are switching from disposables or cigarettes
• Want a kit that fits in your pocket
• Don't want to fiddle with settings
• Value flavour over cloud size
• Want to save money long-term

Choose a sub-ohm coil tank if you...

• Have been vaping for a while and want bigger clouds
• Are happy to learn about wattage, coil resistance and battery safety
• Don't need high nicotine (3–6mg max)
• Want to mix your own e-liquid using shortfills

For roughly 9 out of 10 UK vapers in 2026, a pod kit is the right answer.

The Coil Inside the Pod

Every pod has a coil, even pre-filled ones. The coil is a small heating element wrapped around cotton wick — it warms up when you puff, vaporises the e-liquid touching the wick, and you breathe in the vapour.

Pods can use different coil technologies:

• Mesh coil — a flat strip of metal mesh. Bigger surface area, faster heating, better flavour. The 2026 standard.
• Wire coil — traditional wound wire. Slower, less flavour. Increasingly rare.
• Ceramic coil — mostly phased out. Slower flavour delivery.

Every Vaporesso XROS, OXVA Xlim, Uwell Caliburn, Hayati and Lost Mary kit we stock uses mesh.

PG vs VG: What the Ratio Means

E-liquid is mostly two base liquids: PG (propylene glycol) and VG (vegetable glycerine). The ratio between them changes everything about how your e-liquid behaves.

The two common UK ratios

• 50/50 VG/PG — standard for nic salts. Thin enough to wick through small pod coils. Used in 99% of pre-filled pods and 10ml nic salt bottles.
• 70/30 VG/PG — standard for shortfills. Thick, smooth, lots of cloud. Used in sub-ohm tanks.

The number one mistake new vapers make

Putting 70/30 e-liquid into a small pod kit. The thick liquid can't wick fast enough through the tiny coil, the cotton dries out, and your next puff tastes burnt. Always use 50/50 nic salts in pod kits.

Nic Salts vs Freebase Nicotine

Same nicotine, different chemistry. Quick summary:

• Nic salts — smooth at high strengths (10mg, 20mg). Built for pod kits. Absorb in ~1–2 minutes.
• Freebase — harsh at high strengths. Built for sub-ohm. Best at 3–6mg.

The Compatibility Matrix

Here's exactly what works with what:

Flavour: Does Pod or Coil Tank Taste Better?

This is the most divisive question in vaping. Honest answer:

• Pod kits — sharper, more accurate flavour. The small mesh coil sits close to your mouth and PG carries flavour molecules well.
• Sub-ohm tanks — richer, more rounded flavour at the cost of accuracy. Bigger clouds dilute the flavour intensity slightly.

For ex-smokers and ex-disposable users, pod kits almost always taste better because the flavour profile matches what they were already used to. For experienced cloud chasers, sub-ohm wins for richness.

Cost Comparison

Pod kits are dramatically cheaper to run, especially after the 2026 vape tax.

Frequently Asked Questions

Are pod kits or coil tanks legal in the UK?

Both are fully legal. The UK ban only affected single-use disposables — see our disposable ban explainer.

Can you replace coils in a pod kit?

Some pod kits have replaceable coils (Vaporesso XROS, Uwell Caliburn G4), some require you to replace the whole pod (most pre-filled kits like Hayati Pro Max+ 6K).

How long do pod coils vs sub-ohm coils last?

Mesh pod coils: 7–14 days. Sub-ohm coils: 5–10 days under typical use. Care matters more than format — see make your pods last longer.

Why do my clouds look small with a pod kit?

Pod kits are tuned for flavour and discretion, not clouds. If you want big clouds, you need a sub-ohm box mod with 70/30 e-liquid — but you'll lose nicotine strength options.

Can I put 70/30 e-liquid in a pod kit?

No. The viscosity is too high for small pod coils. You'll get dry hits and burnt taste within hours.

What's the cheapest setup overall?

A refillable pod kit + 10ml nic salts. See cheapest way to vape UK 2026.

The Bottom Line

For UK ex-smokers and ex-disposable users in 2026: buy a pod kit, fill it with 50/50 nic salts at 10mg or 20mg, ignore the sub-ohm gear unless you actively want to chase clouds. The pod-kit-plus-nic-salt combination is what manufacturers have spent the last five years optimising specifically for people in your position.
