How Vape Tanks Work
A vape tank holds your e-liquid and houses the coil that heats it, also called an e-cig tank or vapour tank. It screws onto a box mod with a 510 thread, a universal fitting, so any tank works with any mod whatever the brand. Inside there is a glass section for liquid, a coil in the base, a top-fill cap and an airflow ring to set the draw. Sub-ohm and MTL tanks use prebuilt coils you replace every one to three weeks, while RTAs, RDAs and RDTAs are rebuildable, so you wrap your own wire and wick with cotton for lower running costs and more control.

Choosing a Vape Tank
Start with the draw you want. A sub-ohm tank suits high-wattage DTL clouds and high VG shortfill, while an MTL tank gives the tight, cigarette-like pull that suits nic salts and ex-smokers. If you like to tinker, a rebuildable RTA or RDA rewards you with the best flavour for the lowest long-term cost. Prices run from cheap everyday tanks to premium builds, so there is a vape tank for every setup and budget.
If you are after big tanks for longer sessions, look for bubble glass versions that lift capacity beyond the standard 2ml.
Replacement Coils and Parts
Prebuilt tanks need fresh coils every week or two, and rebuildables need wire and cotton. Keep spare glass and seals on hand so a knock never stops you vaping, and match the e-liquid to the tank: high VG for sub-ohm, 50/50 or nic salt for MTL.
