How Does Wattage Affect My Vape?

Many devices on the market today, including our SERIES-B DNA 75W, let you adjust the wattage to your personal preference. Now, that all sounds fancy, but what does the wattage affect, and how do you find your own ideal wattage?

But, hold on, wattage? I adjust the voltage on my device!

Don’t worry, voltage and wattage are linked. Wattage stays the same across all devices, tanks and coils, so 10W with one vape coil will fire at 10W on another vape coil.

However, if you’re using voltage, the actual power supplied will vary depending on the resistance of your vape coil. For example, 5v on a 1.8Ohm coil will be about 13.5W of power, whereas 5v on a 0.5Ohm coil will be about 48w.

For this article, we’ll be talking about higher and lower power levels, or wattages, rather than specific numbers, so you can continue to use your device in voltage mode if you prefer.

With that out of the way, let’s get into it…


If you prefer a warmer cloud of vapour, then turn your wattage up. Like it cooler? Turn it down.

This happens because the higher the vape wattage, the more power being provided to the vape coil, and the more power, the warmer the coil gets.


When a vape coil is run at a higher wattage, it’s able to create more vapour, thus giving you more nicotine per puff. This also means that the throat hit from your nicotine and PG is increased as well.

If you like a nice, strong throat hit, then use a higher wattage, but if you prefer your vape to be a bit smoother, use a lower wattage. However…


In turn, the temperature of your vape will affect the flavour of your e liquid, and using certain flavours at certain temperatures can really help them ‘pop’.

For example, menthol flavours work better at lower wattages and therefore cooler temperatures, as this compliments the cooling menthol sensation.

On the other hand, creamy or ‘dessert’ type e-juices tend to work better at higher wattages and temperatures, sometimes even letting you pick up on subtle flavour notes that you might have not noticed before.

E-liquid Use

If your vape coil is being run at a higher wattage and producing more vapour, it needs to use more e-liquid to create that vapour.

This is why vapers using sub-ohm vape coils at 40 or 50W or even higher can get through a 10ml bottle of e liquid or more in a day. If you’d rather conserve your e liquid, keep to a lower wattage.

UK Made Premium Vape Juice

Our Premium Vape juice has a range of different flavours to choose from, with everything from juicy fruit, cooling menthol, sweet desserts and classic tobacco.

Choose from a High PG ratio of 70%, providing a satisfying throat hit and rich, dense flavour, or if you're looking for a smoother vape with big clouds, then our High VG ratio would suit you best.

Vape Coil Lifespan

Similarly, running your coils at the higher ends of their recommended wattage ranges can shorten their overall lifespan and you might find them burning out more quickly than when you run them at lower wattages.

If you start to notice a burnt taste on a coil at a higher wattage, sometimes lowering the wattage can get rid of this taste and give you an extra couple of days’ use out of the vape coil.

Inhale Length & Vaping Style

If you like to take very long or deep inhales when you vape, then you may find that you’re not able to reach higher wattage ranges without your vape coil tasting burnt.

This is fairly normal, as while a coil may be able to be fired at a high wattage, it may struggle with being fired for a long time. In this case, just drop your wattage down, but if you take shorter inhales, you can try putting your wattage up.

Battery Life

As you might have already guessed, running a coil at a higher wattage will also decrease your vape battery life as your vape mod needs to pull extra power from the battery to supply those high watts to the coil.

For example, using a 2600mAh IMR battery at around 15W will get you around a day’s use, whereas the same battery at 40w will tap out after just a few hours. If you want to enjoy uninterrupted, high-wattage vaping, make sure you invest in a couple of spare IMR vape batteries and battery safety covers.


Finally, it’s worth considering how closed or open you like to have the airflow ring on your tank when you’re vaping. As higher wattages cause coils to get warmer, it’s beneficial to have your airflow ring more open, as this extra air will help stop the coil from getting too hot and burning.

If you like to have the airflow ring quite closed, to give you that tighter draw, then make sure to keep your wattage a little lower.


So, now you know how the wattage affects your vape, but how do you know what wattage to use? Every coil is ‘rated’ for a certain wattage range. For example, our 1.0Ohm MTL S-Coils are rated for between 14-22w, but the 0.5Ohm DL S-Coils are rated for between 20-30W. You can usually find these ratings on the website, packaging or the coil itself.

Once you know your coil’s wattage rating, start at the very bottom wattage. Then, gradually turn it up by a watt or two at a time, taking an inhale in-between.

If your vape becomes too harsh or hot or tastes burnt, you know it’s a little too high, so turn the wattage back down. Experiment in this way until you find your own perfect wattage.
