Quite simply, sub-ohm vaping refers to the use of a device fitted with an atomizer coil with a resistance of less than 1.0 ohm.
“Sub-ohmers” are able to maximise the overall power output (or wattage) of a purely mechanical power unit, such as the Odyssey 18650M because of the high current draw of a low resistance atomizer. Back in the early days of the E-cig industry, there were no VV/VW devices available, so reducing the atomizer resistance was one of the simplest ways of enhancing the performance delivered by a device. These days, vapers wishing for a device which delivers enormous clouds of vapour (‘cloud- chasers’) enjoy this style of vaping.
As you decrease the resistance of the atomizer, you increase the current (or amperage) your device will use. Higher current not only increases the power to the atomizer, but causes greater heat build up in the battery itself. If you want to make life really easy, Totally Wicked have a range of devices that will power sub-ohm atomizers with built in protection and these devices will cut off if the atomizer resistance is too low for safe use. When sub-ohming with a purely mechanical device, it’s important that you find out the maximum current (in amps) that your battery is capable of safely supplying.
As a general rule, consider the typical operating voltage of a lithium ion battery as 3.7 volts, and the simple calculation of dividing this voltage by the atomizer resistance will tell you the expected current draw. The battery’s maximum current should never be exceeded as doing so risks not just damage to the battery, but injury to the vaper. There’s plenty of information available online, including YouTube videos and Ohm’s law calculators, so ensure that you read-up fully to arm yourself with the knowledge to allow you to vape safely. Of course, our customer service team, or knowledgeable retail assistants are there to help you too.
DRAW STYLE, NICOTINE AND E-LIQUID
Vaping a sub-ohm device produces an enormous amount of vapour, much to the delight of the cloud-chasers. Typically, a sub-ohm tank requires a different style of draw than the more relaxed “mouth draw” associated with starter kits. Sub-ohm vapers tend to ‘direct draw’, rather like using an asthma inhaler. This draw action is facilitated by wide-bore mouthpieces, wide air-flow channels in the tank and large-bore air channels in the atomizer itself. Because of the volume of vapour being inhaled, many sub-ohmers prefer to use an e-liquid with a lower nicotine strength than they may have used previously in their previous e-cigarette.
Strengths of 0.6%, 0.3% and even 0.0% are common when sub ohming. As the desired effect for sub-ohm vaping is often large clouds, many vapers prefer to switch to e-liquid with higher vegetable glycerine (VG) content, VG being the element of an e-liquid responsible for making vapour visible in air. If you venture down the sub-ohm route, you’ll want to try our Diavlo range of e-liquids, as these have been formulated with high VG to PG ratio. Why not visit your local shop to try-out these incredible ranges?
IS SUB-OHM VAPING RIGHT FOR YOU?
Most sub-ohm vapers are dedicated and passionate about vaping, their habit has become their hobby. The knock-on effect of this driving passion is that they’ve spent a lot of time researching and reading-up about the science behind vaping. This vaping style is not for everyone, so if any of the above feels like it’s a step too far for you, then maybe consider a high quality VV/VW, or even a VT device instead. We don’t want to discourage you from trying a sub-ohm device, but we want to ensure that you operate safely, we care about your well-being! If you do still fancy exploring this side of vaping, head along to one of our stores or give us a call, we’ll happily help you make the right choices to suit your needs.
