Sub-ohm tanks are relatively simple to use but given that they are a little more involved than pod kits, we recommend them for people who have vaped before.
Sub ohm simply means that they are compatible with coils that have a resistance lower than 1.0 ohm. This pretty much covers most tanks since it's the replaceable coil, not the tank itself, that comes in different ohms.
Every tank, unless it's a disposable tank, has a replaceable coil, adjustable airflow and easy filling ports for e-liquid, all of which vary across different vape tanks.
Sub-ohm tank variables are what determine if they are more suitable for mouth-to-lung (MTL), a cigarette-style draw where you hold vapour in your mouth then inhale to the lungs, or direct-lung (DL) vaping where you inhale vapour straight to the lungs, like taking a deep breath.
If you're unsure which tank suits you, message us on Facebook or by email and we'd be more than happy to help. What you CAN be sure of is that all our electronic cigarette (e-cigarrete) tanks come from reputable manufacturers who rigorously test their merchandise for safety.
