Sub-ohm tanks are atomizers designed for big clouds. These atomizers require powerful mods, capable of putting out high wattages. Sub Tanks provide a ton of airflow and were originally designed to mimic the experience of dripping, with the convenience of a tank. Now anyone can be a cloud chaser thanks to sub-ohm tanks.
Made for direct lung vaping, sub-ohm tanks utilize pre-built coil heads that are usually 0.5 ohms or lower. Most of these coil heads use cotton wicking. Recently manufacturers have been using other wicking materials like wood pulp and more advanced coils like dual- or triple-mesh. These innovations have had a big impact on flavour production.
How does a sub-ohm tank work ?
A sub-ohm tank works just like a regular vape tank but are geared towards higher-powered setups. They run on replaceable coil heads, which attach to the base of the tank. The e-juice is absorbed into the cotton wick and becomes vapor when it makes contact with the hot coil.
When you puff on the tank, the suction pulls the e-juice towards the coil. Most modern sub tanks feature some type of filling system — usually top fill. Sub ohm tanks also provide wide open airflow. That is what provides the direct lung draw and keeps the coils from getting too hot.
What are the advantages of sub-ohm tanks ?
- More convenient than a rebuildable
- Wide airflow
- Big clouds
- Intense flavour
- High-wattage vaping
- Compatible with high-VG e-liquid
The main advantages of a sub ohm tank are clouds and convenience. They were invented to make sub-ohm vaping more accessible. In the last few years, the performance of sub-ohm tanks has been comparable to rebuildable atomizers. No longer do vapers need to build coils or understand advanced electrical concepts. Sub ohm tanks use replaceable pre-made coils, just like a regular tank. As a bonus, their coils are also compatible with high VG-liquid, unlike most of the higher resistance coils that come with MTL tanks.
On top of that, the flavour you get from a sub-ohm tank is intense. You will taste more flavour at once due to the increased vapor production compared to tanks with a tighter airflow. In some cases, you will even get to experience different notes of your juice: your e-liquid will taste much different on an MTL coil rated for 20 watts than it would on a 200-watt super tank.
Newer sub-ohm tanks allow you to experiment with various coils — for example some have coils that are compatible with temperature control. Combining high performance with a variety of options, sub ohm tanks are the best way to achieve intense flavour and impressive clouds without having to work on your building skills. They come in handy for vapers who want to chuck clouds without all the fuss. Pop in a coil, fill it up and enjoy.
What are the disadvantages of sub-ohm tanks ?
- Not suitable for MTL vaping
- Fast battery drain
- High liquid consumption
- Purchasing coils
The main downside to sub ohm tanks mostly applies to MTL vapers. You won’t get that tight cigarette-style draw, even with the airflow closed. They aren’t as stealthy as the smaller devices and create a trail of vapor everywhere you go. Think of it as a trade-off. The other disadvantages to sub ohm tanks are the price to pay for an easy to achieve sub-ohm experience.
Sub-ohm tanks will drain your batteries faster than regular tanks since they require more power. They will go through a lot more e-juice as a result of this. This can also be dependent on the type of coil you use. Lastly, something to consider before buying a sub-ohm tank is the price of coils. Remember, you will be replacing them approximately once a week. Coils and e-liquid costs can add up quickly, especially if you enjoy vaping on premium e-liquid.
