What are Sub Ohm Tanks?

Sub ohm tanks refer to any vape tanks using low-resistance pre-made coils and running on high-powered mods. To further define “low resistance,” it means a coil falls under 1 ohm. These tanks support big airflows, and always get considerable power supply from mods they connect to, thus capable of pumping out gigantic and dense vapor. They are ideal go-to devices for cloud chasers.

Types of Vape Tanks Explained

There’re a wide collection of vape tanks on the market, coming with various designs and uses. In spite of the great variety, typical vape tanks fall into just three types: MTL (mouth-to-lung) tanks, sub ohm tanks and rebuildable atomizers.

  • MTL tanks: Through narrowing down the mouthpiece and restricting airflows, this type of tanks is meant for MTL draws, like what we usually experience in cigarettes. For this reason, they better fit newbies who would like a smooth transition from smoking to vaping.

MTL vape tanks

  • Sub ohm tanks: They’re outfitted with coils less than 1 ohm, and thus compatible with very high-watt mod machines to spill enormous clouds. Opposite to MTL tanks, these tanks allow vapers to inhale vapors directly into their lungs. This is a vaping style called DTL (direct-to-lung). As a good performer in vapor production, sub-ohm tank is avidly embraced by experienced vapers.

Which Vape Tanks Should You Choose?

MTL Tanks vs Sub Ohm Tanks


In short, MTL and sub ohm tanks mean different styles of vaping—MTL and DTL. Both are really self-explanatory. MTL vaping is when you keep vapor staying in your mouth for a moment before drawing it into lungs. While DTL vaping represents the way vapers inhale vapor directly into lungs with no pauses.

DTL vapers might use MTL tanks sometimes in a mixed way. While not every MTL vaper can adapt to DTL draws from the very start. It’s not that tough though. To take DTL draws, you’ll be like taking in a big breath, and letting vapor go straight into your lungs.

RBAs vs Sub Ohm Tanks


Some pro vapers believe if you’re skilled at building a right coil, RBAs is a definite winner over sub ohm tanks. In essence, that’s a battle between pre-built coils and DIY coils. However, whether we admit it or not, sub-ohm tanks are stepping up their game these days, such as introducing well-crafted mesh coils massively. Some manufacturers have released as satisfying use-and-throw coils to rival manually built ones.

So the fact is, best sub ohm tanks could produce the same great huge clouds, flavors and hits as RTAs. Just be mindful that you should pick products only from trustworthy brands and stores.

But anyways, there do exist some differences between sub-ohm tanks and RTAs. Sub ohm tanks save you from lots of hassles. And if you don’t care about paying more for pre-made coils than built ones, feel free to get them. For those who don’t hate coil builds and want more control and less costs, RBA is the right way to go.

How Long Does a Sub Ohm Tank Last?

With regular maintenance and cleaning, you can rock a same sub ohm tank for years. But if you’re talking about how long its coil lasts specifically, that would be one to two weeks on average. Actual lifespan of coils can vary greatly, depending on the build quality and how properly you use it.
