Nano Tank – What is it in Vaping?

Definition

A Nano Tank is a miniature vape tank designed to deliver mouth-to-lung (MTL) or restricted direct-lung (RDL) vaping in a pocket-friendly form factor. Typically holding 1–2.5 mL of e-liquid, it threads onto compact vape mods or pen-style batteries and uses pre-built or rebuildable coil heads measuring 16–19 mm in diameter. Its purpose is to provide flavour-focused vaping with modest vapour production, making it ideal for higher-strength Nicotine Salt”>nicotine salt e-liquids and discreet everyday use.

Technical Details

Nano Tanks operate using press-fit or screw-in coil heads made from Wire“>Nichrome Wire or Kanthal, rated between 0.6 Ω and 1.8 Ω. Most feature top-fill systems with silicone-sealed sliding or twist caps, adjustable bottom airflow rings, and borosilicate glass or PCTG reservoirs. Variants include:

  • Disposable Nano Pods: integrated 1.2–1.8 Ω coil and 2 mL chamber, discarded when flavour fades.
  • Rebuildable Nano RTAs: 16 mm deck accepting 2.5 mm micro-coils for advanced users.
  • Cross-compatible coils: some brands accept Smok Nord, Vaporesso GTX or AspireNautilus coils.

Power draw ranges from 8–25 W, easily supported by single Battery“>NiMH Battery or 18350/18650 cells in regulated mods.

Usage & Tips

  • Priming:Drip 3–4 drops of nic salt e-liquid directly onto the coil cotton before first use to prevent dry hits.
  • Airflow: Close airflow halfway when vaping 20–50 mg nicotine salts to tighten draw and enhance Hit“>throat hit.
  • Cleaning: Rinse glass and Tip“>drip tip weekly; avoid soaking coil heads in water—replace every 5–10 mL of sweetened liquid.
  • Safety: Never exceed coil wattage limits; high-strength nicotine can cause dizziness if chain-vaped.

History & Context

Nano Tanks emerged around 2016 as manufacturers miniaturised sub-ohm tanks to meet demand for stealth vaping. Early 22 mm “mini” tanks shrank to 16–19 mm when pod systems gained popularity, bridging the gap between cig-a-likes and full-sized mods. Today, they remain a staple for Australian vapers navigating nicotine prescription laws by pairing discreet hardware with nicotine salt formulations.
