Your Trusted UK Guide to Vaping

At VapeSales, we help vapers choose the right vape kits, e-liquids, and coils with simple, evidence-based guidance. Whether you're upgrading, switching from smoking, or exploring new flavours, our UK-compliant range covers everything from pod kits and sub-ohm devices to quality nic salts and shortfills.

Choosing the Right E-Liquid

Your vape experience depends on the liquid you pair with your device. MTL pods work best with 50/50 or nic salt blends, while DTL tanks deliver smoother clouds with high-VG shortfills. If you're unsure which strength suits you, our Nicotine Strength Guide makes it easy.

Getting the Best Performance

A well-primed coil and correctly filled pod make a huge difference in flavour and longevity. Learn how to avoid dry hits and extend coil life with our coil priming guide, or follow our step-by-step pod filling tutorial for smooth, mess-free refills.

MTL vs DTL — Find Your Style

MTL offers a cigarette-like draw with higher nicotine options, while DTL provides bigger clouds at lower strengths. Not sure which fits you? Explore our Vaping Styles Guide for a clear breakdown of airflow, coil resistance, and ideal e-liquid pairings.

Frequently Asked Questions

Which e-liquid should I use with this product?

Most pod and MTL devices work best with 50/50 nic salts, while sub-ohm tanks pair well with high-VG shortfills. Always check the coil resistance: higher ohm = MTL, lower ohm = DTL.

How long do coils or pods usually last?

Most coils and pods last around 1–2 weeks depending on e-liquid, wattage and usage. If flavour drops or you notice a burnt taste, it’s time for a replacement. See: How to Prime Coils & Pods.

Is this product TPD-compliant?

Yes — all products sold at VapeSales UK meet UK TPD regulations, including nicotine limits, child-safe caps and correct labelling.

What nicotine strength should I choose?

New switchers often start with 10–20 mg nic salts in MTL pods, while DTL users prefer 0–3 mg shortfills. Find your perfect level with our Nicotine Strength Guide.
