Best Vape Tanks UK — Top Fill, Sub Ohm & MTL Tanks Compared

Picking the best vape tank for your mod can feel tricky when there are so many brands, coils, and capacities to think about. At our store we stock a wide range of vape tanks, from simple beginner options to big cloud chasing sub ohm tanks. In this guide we walk through some of our most popular tanks, explain what each one actually offers, and help you find the one that suits your vaping style.

Quick heads-up: UK vaping regulations stipulate that the capacity of a vape tank should be no more than 2ml for TPD compliance. Many tanks come with bubble glass extensions that increase capacity — we've noted both where applicable.

Quick Comparison: Which Vape Tank Is Right for You?

Here's a side-by-side look — makes it easier to decide.

Which Vape Tank Should You Actually Pick?

What is a Sub Ohm Tank and How is it Different from a Normal Tank?

A sub ohm tank uses a coil with a resistance under 1 ohm, which lets more power pass through and creates bigger clouds and warmer vapour. Normal MTL tanks use higher resistance coils for a tighter draw closer to smoking. Sub ohm tanks need a mod that can handle higher wattage output safely.

Do I Need a Special Mod to Use These Vape Tanks?

Yes, sub ohm tanks like the Valyrian 3 or Z Max need a mod capable of higher wattage output, usually 40W or more depending on the coil fitted. Smaller tanks like the Innokin Jem work fine on lower powered devices. Always check the coil's recommended wattage range before fitting it.

How Often Should I Change the Coil in My Tank?

Most coils last between one and three weeks depending on how much you vape and how sweet your e-liquid is. You will usually notice a burnt taste, weaker flavour, or reduced vapour production when a coil is coming to the end of its life and needs replacing.

What is the Difference Between Bubble Glass and Straight Glass?

Bubble glass has a rounded shape that holds more e-liquid than a straight glass section of the same tank, often adding an extra 1ml to 2ml of capacity. Many tanks, including several on this page, come with both a bubble glass and a spare straight glass in the box.

Can I Use Nic Salts in These Sub Ohm Tanks?

It is not recommended. Sub ohm tanks and their low resistance coils are built for high VG e-liquid at lower nicotine strengths, usually 3mg or under. Nic salts are made for lower power MTL devices, and using them in a sub ohm tank can feel harsh and is not how they are designed to work.

What E-Liquid Should I Use With a Sub Ohm Tank?

Sub ohm tanks work best with high VG e-liquid, usually 70VG or higher, since this thicker liquid wicks properly through low resistance mesh coils. Using thin, high PG e-liquid in a sub ohm tank can cause dry hits and reduce coil lifespan.

How Do I Stop My Tank From Leaking?

Most leaking happens from overfilling, a damaged O-ring, or a worn out coil, so check all three if you notice liquid escaping. Tanks with a proper top fill and top airflow design, like the Geekvape Zeus and iTank, are generally much more leak resistant than older bottom airflow designs.

Are All These Tanks Compatible With Any Mod?

Every tank on this page uses a standard 510 thread connection, which fits the vast majority of mods on the market. The only thing to check is whether your mod can safely output enough wattage for the coil resistance you plan to use, especially with lower resistance sub ohm coils.
