Vape terminology gets thrown around a lot without much explanation — tank, coil, 510 thread, drip tip. None of it is complicated once you see what each part actually does and how they fit together, and understanding the pieces makes troubleshooting a lot less like guesswork.
The power source for the entire device — built-in and sealed on most disposables, pods, and pens, or a removable 18650/21700/20700 cell on most box mods. Everything else in the device draws its power from here, and battery capacity is the main factor behind how long a device runs between charges. We cover charging types and habits in more depth separately.
The small heating element that actually vaporizes e-liquid — current from the battery heats a resistance wire wrapped in a wicking material, and the saturated wick vaporizes on contact. We go into coil resistance, materials, and lifespan in a dedicated guide, since it's genuinely the part most worth understanding well.
The reservoir that holds e-liquid and feeds it to the coil's wick by capillary action. A tank is generally refillable and reusable across many coil changes; a pod is often smaller and, depending on the system, either refillable or pre-filled and disposable once empty.
The standardized screw connection joining tank to battery on the vast majority of vape hardware — both the physical mount and the electrical contact in one piece. We explain exactly how this connector works, and where compatibility can still trip you up, in a dedicated piece.
The part you actually draw from, sitting at the top of the tank or pod. On many devices it's swappable for a different shape, width, or material — purely a comfort and airflow-feel preference, with no real effect on vapor production itself.
An adjustable vent, usually a ring or slider near the base of the tank, that changes how much air mixes with vapor on the draw. More open airflow gives a looser, airier draw with more vapor volume; more restricted airflow gives a tighter draw closer to a cigarette's feel, with more concentrated flavor.
Most are, thanks to the shared 510 thread standard, but not universally — some devices use proprietary connections, and even among 510-thread devices, a wide tank can physically overhang a narrow battery even though the threading itself connects fine.
"Atomizer" is really the broader term for the whole vaporizing assembly (housing plus coil); "tank" specifically refers to the e-liquid reservoir portion. In casual use the two terms often get used interchangeably for the same refillable unit.
No — coils are specifically designed as the replaceable wear part. The tank itself, along with the drip tip and airflow control, typically lasts through many coil changes before it needs replacing.
