Tanks

A vape tank is a vital component of most vaping devices. It holds your e-liquid and houses the coil that heats the liquid into vapour. Available in a wide range of sizes, styles, and technologies, vape tanks can dramatically influence flavour, vapour production, airflow, and overall vaping satisfaction.

From sub-ohm tanks built for cloud-chasing to mouth-to-lung options tailored for ex-smokers, there’s a vape tank to suit every style of vaping. Choosing the right one can elevate your experience — or limit it — so understanding how they work and what makes them different is essential.

Tanks

What Is a Vape Tank?

A vape tank is the e-liquid reservoir attached to a vaping device or mod. It connects to the battery via a 510 thread, contains a replaceable coil, and often features adjustable airflow control.

When you activate the device, the coil inside the tank heats up, vaporising the e-liquid soaked into the wicking material (usually organic cotton). The result is the vapour you inhale.

Main Types of Vape Tanks

1. Sub-Ohm Tanks

Sub-ohm tanks are designed for Direct-to-Lung (DTL) vaping and use low-resistance coils (typically below 1.0Ω). These tanks focus on maximum vapour production and work best with high-VG e-liquids.

Key Features:

  • Large airflow channels
  • High wattage compatibility (30W+)
  • Ideal for cloud-chasing and bold flavour
  • Best used with 70/30 VG/PG e-liquids or higher

Who they’re for: Advanced vapers and cloud enthusiasts who enjoy warm, dense vapour and bold flavours.

2. Mouth-to-Lung (MTL) Tanks

MTL tanks replicate the draw of a traditional cigarette, making them ideal for those switching from smoking. They use higher resistance coils and are optimised for low-wattage devices.

Key Features:

  • Tighter airflow
  • Lower vapour output
  • Efficient with e-liquid and battery life
  • Best used with 50/50 VG/PG or nicotine salts

Who they’re for: New vapers or those who prefer a discreet, cigarette-like inhale.

3. Rebuildable Tanks (RTAs, RDTAs)

These are advanced tanks that allow users to build and install their own coils rather than using pre-made ones. Popular among hobbyists and DIY vapers.

Types:

  • RTA (Rebuildable Tank Atomiser): Has a tank section for e-liquid storage.
  • RDTA (Rebuildable Dripping Tank Atomiser): Combines dripping and tank features.
  • RDA (Rebuildable Dripping Atomiser): No tank; requires manual dripping.

Key Features:

  • Full control over coil builds and wicking
  • Enhanced flavour and vapour (with proper setup)
  • More affordable over time (build your own coils)

Who they’re for: Experienced vapers who want full customisation and are confident in coil-building and maintenance.

Key Components of a Vape Tank

  • Drip Tip: The mouthpiece. Often removable and available in various styles.
  • Top Cap: The section you unscrew or slide to refill e-liquid.
  • Glass Tube/Reservoir: Holds the e-liquid (typically 2ml in UK TPD-compliant tanks).
  • Coil Head: The heating element inside the tank, usually screw-in and replaceable.
  • Base/Airflow Ring: The bottom section that controls how much air enters the tank.

How to Maintain Your Tank

  • Clean regularly: Rinse with warm water every few refills to prevent flavour build-up.
  • Replace coils: Swap every 5–10 days or when flavour drops.
  • Check for leaks: Ensure O-rings are intact and the coil is properly installed.
  • Prime coils: Always prime a new coil before use (saturate with e-liquid and wait a few minutes).

Choosing the Right Tank for You

Vaping Style Ideal Tank Type Coil Resistance E-liquid Type Power Range
Mouth-to-Lung MTL Tank 1.0Ω or higher 50/50 or Nic Salts 10–20W
Direct-to-Lung Sub-ohm Tank Below 1.0Ω High VG (70/30) 30–100W+
DIY & Custom RTA / RDTA / RDA User-built Any compatible liquid Customisable

Conclusion

Vape tanks are much more than just e-liquid containers — they’re a core part of your vaping experience. The right tank can enhance flavour, produce impressive vapour, and match your ideal draw. Whether you’re after a powerful sub-ohm setup, a beginner-friendly MTL experience, or a full DIY rebuildable system, there’s a tank out there to suit your needs.

Make sure to pair your tank with the correct e-liquid and coils, maintain it well, and enjoy a smooth, consistent vape every time.
