The Complete Sub-Ohm Vaping Guide

Fancy Wording For Faster, Stronger And More Powerful


You know when you watch a TV ad for a tablet and feel totally reassured with the Pentium II Chip Processor, but literally have no idea what it does? If you gave up physics before GCSE, you might be feeling the same reaction when it comes to Sub-Ohm vaping. Turns out, we’re a friendly bunch, so here’s the low-down on what Sub-Ohm vaping is, how to do it, why to do it, and more.


Sub-Ohm Vaping Is Turbo-Charging Your Engine.  Please explain? (sure).


Back in its baby days, vaping had one thing going for it. Finally, something that’s 95% safer than smoking and now officially endorsed by the NHS for quitting smokers. You basically had a limited choice of rubbish ciga-clones that delivered zilch power, squat flavour and no clouds. The industry had to up its game. Enter Sub-Ohm Vaping.


Sub-Ohm vaping involves vaping on a device that has a resistance of less than 1.0 Ohm. If Ω means nothing to you, the results will.


Sub-Ohm vaping offers:

  • Higher power outputs
  • Higher firing temperature
  • Beastly clouds and epic flavour
  • A truly personalised vaping experience
  • Some die-hard dedication to Ohm and Jules laws that you can pay attention to (or not)

For the physics geeks:


The laws of physics mostly serve, you know, to keep stuff in place. Your microwave doesn’t fly into outer space because gravity holds it down. Your clouds will however billow well into your neighbour’s lawn with Sub-Ohm vaping and here’s why.


When resistance is decreased on the device (measured in Ohms), the battery will increase the power output (you’ll know this if you choose your wattage). This subsequently ramps up the amps needed to supply current. While this puts a bit of strain on the battery, the solution is simple. It’s called top-of-the-range devices. Still, we need to explain the wording.

  • Ohms (vaping’s OH-EM-GEE): An Ohm is a unit of measurement that refers to resistance. Like feet refer to length. Or pints to volume. Sub-Ohm, as the name suggests, refers to resistance below 1.0 Ohms, although many clearomizers measure between 1.2-2.0 Ohms.
  • Calculating Ohms: Ohm’s law applies to vapers who need to know the following: the higher the resistance, the cooler the e-liquid (and the lower the resistance, the hotter the e-liquid). Volts divided by resistance = number of amps. Before you “what has two thumbs and doesn’t give a toss”, remember that the result has knock-on effects when it comes to flavour and cloud production. Flavour and cloud chasing is a thing. No, really.

  • Why Sub-Ohm At All?


    Because it’s better. Seriously, you can buy all the pistachio creme brulee or Heisenberry in the world, but Walter White would be ashamed of you if you weren’t Sub-Ohm vaping.


  • Monstrous Cloud Production:  Sub-Ohm vaping will generate thicker, denser and bigger clouds, making it the go-to choice for cloud chasers digging their high VG juices. Blowing a nuclear cloud out your mouth might not go down too well in an office doorway, but if you’re lucky enough to spend your days in a vape-friendly environment, this is literally the bee’s knees. A lot of vapers balance out the pressures of vaping etiquette by carrying a vape pen to work, then rushing home for Sub-Ohm clouds.
  • Smoother, more intense flavour: We’ve already covered how hotter temperatures offer more intense flavour, and the industry is right on it. Manufacturers have specifically developed some e-liquids to accommodate low resistance, Sub-Ohm devices. Dinner Lady’s range are perfect for Sub-Ohm vaping. Also coming highly recommended, are the trustworthy Element and our in-house 70/30 flavours like Watermelon Candy Coconut, Apricot Mango and Caramel Coffee Custard.
  • A lung hit that satisfies: Some vapers, e.g. stealth vapers or “MTL” Mouth To Lung vapers aren’t looking for a deep lung-hit. Those who are, however, will find that Sub-Ohm vaping delivers- like woah. There are, of course, Sub-Ohm tanks- basically a tank with a Sub-Ohm coil in it. Do not however make the rookie mistake of thinking that closing down airflow on a Sub-Ohm tank will get you a good MTL hit. That’s like saying milk and beer are identical, because they’re both something you drink via a glass. For Sub-Ohm tanks, click here.
  • Enjoyment and experience over nicotine hits: You’ll never be robbed of your nicotine hit, regardless of how you vape. As long as you choose some form of nicotine strength (or save dough on Short Fills with free nic shots), you’ll still get your fix. Sub-Ohm vaping really is more about the experience, though. The clouds and the flavour take priority over the quitting smoker’s desperate need for nicotine. You may also find you get less of a throat hit from Sub-Ohm.

  • How To Sub-Ohm


    Back in the dark ages, if you wanted to Sub-Ohm vape, you needed to buy a mech tube or box mod that used external 18650 batteries, an external charging bay, Kanthal wire and organic cotton for wicking. Just typing that was a lot of work. Nowadays, all you need is a good old Sub-Ohm tank and a mod that can push out more than 50 Watts (most of these).


    Three Ways To Enjoy Sub-Ohm Vaping:


  • RDAs: RDAs are rebuildable drip atomizers, a.k.a Drippers. These were the original way to Sub-Ohm, although with one hand holding the mod and one hand dripping, this is for the die-hard aficionado lucky enough to have two hands free. These contain a deck where coils are built and attached using a screwdriver, with cotton for wicking. You drip the juice directly onto the coils, and wick before every few puffs. Flavour winner.
  • RTAs: RTAs are rebuildable tank atomizers. Basically, for people who want to build coils but don’t fancy dripping. RTAs are essentially Sub-Ohm tanks that require a bit of coil building (in exchange for the freedom to create coils that give the exact experience you want). Recently, many RTAs have been geared towards Sub-Ohm vapers with appropriate airflow options. Actually, you can even get a hybrid RDTA.
  • T-t-t-Tank: Sub-Ohm tanks use disposable, pre-made coil heads, which is great for avoiding hassle. Tanks like the Atlantis Aspire and Kanger Subtank are your best bet. Inching closer to the RDA/RTA experience, you can also go for the Aspire Cleito and Vaporesso NRG, although the full range, including SMOK are all brilliant. Bear in mind that Sub-Ohm vaping will go through a lot of juice, but most Sub-Ohm vapers feel it’s totally worth it.

  • How Do I Figure Out The Best Resistance For Sub-Ohm Vaping?


    Depending on the device and the manufacturer, most atomizers will range between 0.2-0.5 Ohms. Vaping resistance charts are great for figuring out how the resistance and voltage should match up, plus they’re handy for showing which combinations are safe.

    Red shows resistance and voltage combinations that could damage coils or equipment.

  • Amber shows combinations that are too weak to produce the right vapour.
  • Green is Goldilocks’ spot-on porridge, and what to aim for.


  • No matter your level of experience, it’s important to follow these guidelines as an essential safety component to something that can go dangerously wrong if you’re just “messing around.” We wrote an entire blog post on general vape safety (and the myths surrounding exploding vapes), so have a read here.


    Sub-Ohm Safety (we’re mentioning it for a reason)


    If you’re looking to Sub-Ohm, educate yourself. No-one is asking you to become Sheldon from The Big Bang Theory, but you need to know what you’re doing. Follow the guidelines below as law (they are, after all built on the laws of physics), or shoot us a message any time- contact details at the end.

    NEVER use a hybrid mech mod with a non-hybrid safe tank. “Extremely dangerous” doesn’t even begin to cover this one. The tank here must have a protruding 510 pin. If you’re unsure, don’t take risks.

  • The safest way to Sub-Ohm vape is with a regulated box mod like the SMOK Alien, Vaporesso Revenger or Innokin CoolFire IV.
  • Be battery safe and always use authentic, non-damaged batteries suitable for Sub-Ohm vaping. 95% of people use 18650 batteries. Make sure you never exceed the amp limit on your batteries. If you don’t know, ask. IMR or hybrid lithium batteries are what you’ll be asking the vendor for- these are protected against failure.
  • Mech mod users with a Sub-Ohm tank should make sure it’s always properly vented. Never use a mod that doesn’t have visible battery venting holes. If reading this made you want to vent because SHUT UP WITH ALL THE PHYSICS, stick to a box mod and speak to one of our know-it-alls.

  • Of course, you don’t have to Sub Ohm. There are vape pens, starter kits, value kits as low as £10. 2018 is the Pod Mod year, and if squish-to-vape sounds like fun, try out a Squonk Mod.


    The great thing about vaping is the sheer variety. Check out our full range of e-liquids, accessories, plus our sale. For more about vaping in general, pop into one of our stores, get in touch or read our other blog posts.


    Sub-Ohm vaping is pretty sensational. We wouldn’t have written this if it weren’t.
