Vapers who make the switch to the sub-ohm way of life generally report a significantly enhanced vape experience, with a major boost in vapor production, flavor, and overall satisfaction. Because the technology and science behind sub-ohm vaping allows for larger, more flavorful vapor clouds and a nicotine-rich, smooth experience, it’s becoming a highly popular method in the vaping community.

We receive a huge number of questions about sub-ohm vaping: what it is, how to get started, and the best product options on the market. We decided it was time to put together a handy sub-ohm vape guide so that you can finally try it out. And if you’re already an experienced sub-ohm vaper, we haven’t forgotten you either – our guide includes 10 of the absolute best sub-ohm tank options out there for this year.

What is Sub-Ohm Vaping?
Although sub-ohm vaping is rooted in some slightly complicated scientific concepts, the basic idea is pretty straightforward. Essentially, sub-ohm vaping refers to any vape experience that utilizes a device with atomizer coils that function at a resistance level of less than 1 ohm. The method is named after Georg Ohm and Ohm’s Law, the scientific principle on which sub-ohm vaping is based.
Ohm discovered that the lower the resistance and the higher the voltage of a given setup, the more electrical current that can pass through it (and vice versa). At first, vapers tried to use massively powerful batteries to reach the higher voltage levels but quickly found that they were limited by amperage.
Instead, it was discovered that reducing resistance (and therefore allowing increased current flow) was the key to the giant, fluffy vapor clouds most vapers dream of. For some time, vapers had to take a certain amount of risk in their approach to sub-ohm vaping with unregulated and DIY devices, but now there are a huge number of high-quality, professionally-made sub-ohm devices that make it a safe, user-friendly experience.

What are the Benefits of Sub-Ohm Vaping?
Sub-ohm vaping has three primary advantages: your vapor will be warmer, tastier, and produced in generous amounts. These factors make it an overwhelming favorite for cloud chasers and flavor connoisseurs alike, especially as sub-ohm vaping becomes easier than ever with specially-designed tanks that eliminate all the hassle. 

Sub-Ohm Safety
Of course, like any vape technique, sub-ohm vaping requires a certain amount of effort on your end to ensure a completely safe, issue-free experience. Vaping of any type involves a battery-powered device that’s designed to heat up to a high temperature, so it absolutely makes sense to have a healthy respect and care for your device and technique.
You’ll want to keep your mod clean on a consistent basis, including contacts, vent holes, threads, and the switch. If your switch is spring-loaded, pay attention to the “feel” of it – once it starts to feel worn out, replace it quickly. Also, check that your mod is in the locked position when not in use, to prevent any accidental firing. You should only ever use quality batteries from a reputable brand and throw out any damaged batteries immediately.
Additionally, never use an unvented mod for sub-ohm vaping. Not only will the results be a less than optimal experience, but you’ll be at serious risk for a dangerous incident to occur. There’s no such thing as too many or too large of vents when it comes to a sub-ohm setup, which is why you’ll typically see generous venting on professionally-made sub-ohm tanks. Finally, choose a mod with a low voltage drop for the best possible results. Keeping these things in mind will ensure you have a great sub-ohm experience, every single time.
