Above-Ohm Vaping vs Sub-Ohm Vaping

Above-Ohm (1+) Vaping vs Sub-Ohm Vaping

More and more people are starting to vape every day. With the flood of new types of devices on the market, and many of our old favorites no longer being produced, a lot of experienced vapers will be looking for new devices as well. When going to pick out a vape, whether it’s your first or the next in a long line of upgrades, you may be wondering which type is right for you. There are more devices on the market than you can count so to keep things simple we will break down the two most common types. Then your favorite Pink Spot Vapors employee can help you find the device in that area that will best suit your vaping needs.


regular ohm coilAbove-ohm vaping, or vaping with a device that uses coils that read at 1 ohm or higher is where most experienced vapers started at one time or another. Though coils can be anywhere over 1 ohm, the most common coils read either 1.8 ohms or 2.5 ohms. The tanks that use these coils tend to be smaller in size and can be run on both small low powered devices and larger more powerful devices. Having a larger more powerful device will not give you a more powerful hit while using coils of 1 ohm or higher; because these coils can only handle a small amount of power. Using more power will only burn out your coil and cause your ejuice to taste terrible. You also need to know whether you are using a single or dual coil. Dual coils will allow you to use a slightly higher power setting and give you a small boost in vapor production, and may also improve flavor. Knowing whether you have a single or dual coil is very important while using coils that read over 1 ohm. For example, a single coil that reads 1.8 ohms can voltage anywhere from 3.0v to 3.5v. We recommend avoiding wattage mode on coils of this type, as most devices do not offer a low enough wattage setting to prevent your coil from burning out prematurely. Now in the case of a dual coil reading 1.8 ohms you can use a bit more power. You can run up to 4.3v as well as use wattage settings from 6.5w to 9.0w for best results. A dual coil consists of two coils running together in one coil unit and therefor can handle more power at once.

The other major difference in vaping devices using coils over 1 ohm is the draw you must use to get the best performance out of your device. With this type of coil you want to use Mouth-to-Lung hits (very similar to when you smoke a traditional cigarette). As you take a draw, you are pulling juice into the coil through the wicking material. The coil inside this wicking material is being heated by electricity and vaporizing the ejuice. You want to pull lightly, draw the vapor into your mouth and then inhale it from your mouth into your lungs. If you pull too hard on a device using this type of coil system, the wicking material can become over saturated and the heated coil will not be able to vaporize that amount of ejuice. This can cause the excess juice to leak from the bottom of the tank or even be sucked up into your mouth. Vaporized ejuice can be delicious (such as Pineapple Whip!), but unvaporized ejuice can be quite the opposite. Due to the relatively low power of the coil, it cannot vaporize a large amount of ejuice at one time. This allows you as a vaper to use a wide range of nicotine levels from 0mg, 3mg, and 6mg all the way to 24mg and 36mg. Near the end of your coil’s life, it may not run as efficiently as it did as a fresh new coil. This may mean you need to pull softer to avoid flooding the wicking material, or if you are able, turn the power up a little to help the aging coil function better.

sub ohm coil
Sub-ohm vaping or vaping with a device that uses a coil that reads less than 1 ohm, used to be considered a more advanced form of vaping; reserved for the dedicated hobbyist. With the introduction of sub-ohm tank systems with prebuilt coils, this is no longer the case. More and more vaping novices are choosing to skip the introductory, low powered, “beginner” devices, and start their vaping tenure using a more powerful device that can produce a larger cloud, more satisfying hit, and more flavorful vaping experience. Sub-ohm coils tend to be used in larger tanks with more juice capacity, and on larger more powerful devices. Usually the devices are larger to allow for more battery capacity; since using higher levels of voltage or wattage requires more Milliamp hours or MaH to power the coils all day. There are however smaller devices with the capability to run these more power-hungry coils. Just don’t expect them to get you through a full day of vaping. There is a much wider variety of sub-ohm coils to fit the needs of many different vapers. Coils ranging from 0.15 ohm to 0.9 ohm, containing single coils, dual coils, and even up to dodeca (12) coil units. These coils can also handle a wide range of power settings from 3-8v or 5-220w. This can give the vaper much more choice in exactly how they want their device to perform. Due to the wide range in choice and performance ability, most coil manufacturers have taken to printing the suggested power settings for each coil on the side of the coil unit to avoid confusion. So if using a sub-ohm tank system check the suggested power settings for your coils.

Sub-ohm coils also require you to draw differently to allow the coil to function properly, and to give you the best performance from your device. A Straight-to-Lung draw is used when sub-ohming. As you take a draw, the vapor is going directly from your device to your lungs. Just like breathing. Due to the high levels of power being pushed through this type of coil, the vapor can become very hot. Keeping your airflow open to a larger setting can help keep sub-ohm coils cool. Sub-ohm coils also function better the harder you pull on your device. Where pulling too hard on a coil 1 ohm or higher can cause the coil to flood, sub-ohm coils count on you pulling harder to help the proper amount of juice to flow into the coil, as well as to create more airflow to keep the coil cool. Pulling too softly can cause to much juice to collect on the coil, and cause it to leak; or result in too much heat buildup, and cause the vapor to become uncomfortably hot or burnt. Pulling on a device using a sub-ohm coil is a lot like pulling on a hookah. Long pulls directly into your lungs will give you the best flavor and results in most cases.

Though these two types of vaping seem to be very different it is important to remember these devices are still basically the same thing. They are simply a power source used to heat a coil that vaporizes your favorite ejuice (check out Strawberry Griddlecake). They may require more power or less power, more airflow or less airflow, and a specific type of pull to get you the best performance; but they all need to be used safely. If you have any questions about the best way to use your favorite vape, please call, email, or come into your nearest Pink Spot Vapors location. We will be more than happy to walk you through exactly how to best use your device.

We created PSV in 2009 after being disappointed constantly with the quality of liquid and customer service in this industry. Our mission is to create the best quality and most unique eJuice flavors in the world. We only use Pharma grade nicotine, U.S. food grade 100% kosher PG/VG and food grade flavorings.



A good rule of thumb is to draw as hard as the device allows… and then slightly harder. Let the device guide you. The article is very correct. So many people try to get a better hit by “sucking hard” on a low airflow, above 1 ohm device (BCC, IJust, Protank2 &3 or similar.)

On the other side, many folks “sip” on a subohm device (IJust 2, Melo 2, 3 &4, Alien Baby Beast Big Baby, Super Mini, and almost all other new tanks and Mods sold after 2016) that is designed to have a full pull. A full confident draw allows cool air to smooth out the heat of the more boisterous newer coils.

Match your draw to the allowed airflow for best results.

First, I want to thank for being the great company that you are!! The only e-juice I like is a pink spot vapor! Secondly, thank you very much for the explanation on sub-ohm and above-ohm vaping. I am not new to vaping, but I used the same one for several years until they stopped making parts for it. I took a step up and got a much bigger, powerful device about a year ago and I still didn’t understand all the different coils that were included in the kit. Your explanation helped a lot. You guys ROCK!!!


Best definition of MTL/DL I have ever read. There is far too many self serving informational write ups being distributed. The information in Above-Ohm (1+) Vaping vs Sub-Ohm Vaping is true to my experiences as I see it.

Being fairly new to vaping, this was an extremely helpful definition of the two types of vaping, as well as the methods for utilizing the two different ways ( MTL and DL). Thank you for the informative article, I am today 2 days cig free!!
