Why Does A Vape Device Get Warm?

A vape device getting warm is nothing out of the ordinary. They were designed to create heat, so it’s only natural that they would get warm. Think back on other electronic devices that use batteries, and you’ll realize that just like your laptop or your gaming console, they can get hot or warm after prolonged use. 

However, excessive heat could be a sign that something is wrong with your device, and although most vape devices are regulated, meaning that they come with safety features that prevent the battery from overheating or venting (except for mechanical mods), you should still be keen on figuring out what exactly is wrong with your device if it gets too hot to touch. 

In the following sections, we’ll go over some of the possible reasons for why this could be happening, and we’ll tell you exactly how you alleviate the situation. So let’s start with the number one reason why this could be happening. 

Chain Vaping: Number One Reason for Vape Devices Getting Hot

Often if a vape is getting too warm or hot, it is because you’re chain vaping. In fact, this might be the number one reason why vapes get too hot. As explained earlier, vapes are designed to get hot so they can evaporate the e-liquid. If you are chain vaping, you’re not allowing the coil to cool down before making it get hot again, which in turn maintains the device at a higher temperature. In fact, devices with temperature control can get as hot as 300°C / 570°F and although this is inside the coil, technically, if the coil doesn’t have enough time to cool down, it transfers this heat to the outside of the vape device, making it warm. 

If this is the case, the solution is simple. Stop vaping for a while and allow the coil to cool down. This will allow the temperature to go down again, and the heat will dissipate. 

Juice Flow Control Closed

Another reason why your vape is overheating might be because of your device’s juice flow control. Many box mods nowadays come with juice flow control, allowing the user to control how fast the wick is saturated with vape juice. If your juice flow control is too low or closed, there will be no vape juice going to the wick, which burns the cotton and heats up the coil. The fix to this is simple, just open the juice flow control so vape juice can quickly saturate the coil. Once that’s done, you’ll have a cooler vape. 

High VG Vape Juice

If your vape is getting too hot, there is also the possibility that you’re using a vape juice with too much vegetable glycerin. Unlike propylene glycol, which is liquid, vegetable glycerin tends to be more viscous, meaning that it behaves more like a thick substance rather than a thin liquid. It has a harder time moving from the tank to the wick and a harder time evaporating. If you are vaping on a high VG juice, this could be the culprit for why you feel your vape getting hot, although this will also be accompanied by dry hits (not being able to inhale any vapor) and burnt wicks. If you’re experiencing any of these symptoms or possibly all three, your vape juice could be responsible for your vape getting hot. 

A quick fix would be to change the juice, another fix which is a hack we talked about in another blog, is to use a safety pin to slightly poke one or three holes into the coil so the vape juice can flow faster and it has more room to reach the coil.

Check Your Airflow

If the air in your vape device is too hot, you should check your airflow control. The reason why the vapor created by your vape device might be too hot could be for several reasons, but one of them could be that you have your airflow control completely closed. If this is the case, double-check your airflow control port which will most likely be at the base of your atomizer, and open it wide to let the vapor cool down. If this doesn’t work, it’s likely that your wattage is too high. 

Your Wattage Is Too High

If you are experiencing hot vapor and a hot vape device that becomes warm to the touch, then it is very likely that your wattage is way too high. This is a frequent occurrence, especially among variable wattage box mods. Users tend to increase the wattage in order to create bigger clouds, but at the same time could make the coil reach too high a temperature. If this happens, simply turning down the wattage should do the trick. However, we do recommend that after you turn down the vape, you stop using the device, so it has time to cool down. 

Using the Wrong Recommended Wattage For Your Coil 

Another error tied with your device getting too hot is not using the recommended wattage that is written on your coil. If you have a variable wattage vape that most likely came with spare coils, you’ll notice that each of them has recommended wattages engraved on the coils themselves. If you were to use a wattage that is outside the range of the recommended wattage, you’ll most likely burn the wicking and produce excess heat, making the coil super hot. Luckily there is an easy fix for this; before you install your coils, make sure to check the recommended wattage and start from the lowest temperature and make your way up, ensuring that you are staying within the recommended range. This should prevent your coil from becoming too hot. 

Using an Exotic Coil

Another common reason for a vape becoming too hot is that you are using exotic coils. If you recently purchased exotic coils, like Clapton coils or coils that use more than one wire or have exotic designs, these coils tend to run hotter than regular coils. They also have a lower ramp-up time which means they reach higher temperatures faster, which means your vape device will get hot quicker. With exotic coils, there really isn’t much you can do, you can open up your airflow completely, but if you notice that adjusting the airflow control does not work and the vape gets hot, we suggest you change your exotic coil for a normal one. 

Check for Coil Gunk

Another issue that could be happening is that you have a buildup of coil gunk. This is a normal occurrence that happens to every coil, premade and rebuildable coils alike. When too much coil gunk gathers on your coil, it makes it harder for the coil to absorb vape juice, making the temperature rise much faster than it would normally. When this happens, the vape device will get hotter than what you’re accustomed to. Fortunately, there are two fixes for this, one which is the fastest fix but more expensive, is to switch to a new coil. If you have more patience, you can clean your coil (you can learn how to do this by reading this blog)and get rid of any coil gunk, and this should also fix the problem. 

Check the Battery

If the section where the batteries are housed gets warm, it could be the batteries. If this is the case, you need to exercise some preventive measures. But it really all depends on how hot the batteries get.

If you take out the batteries and they are slightly warm, but you can hold them, then they should be okay. However, if you take out the batteries and they are too hot to the touch, where you can’t hold them in your hand for less than 10 seconds, then you need to quickly place them away from flammable objects and let them cool out. 

If the exterior of the battery housing is already too hot, do not take out the batteries. Instead, take out the tank or atomizer, put the box mod away from flammable objects, and see if it cools down.

At this point, if the box mod has cooled down and you can check the batteries, see if they exhibit any damage. If they are bulging or hissing, this is a sign that they are coming dangerously close to overheating. Quickly move them away from flammable objects, preferably outside your home, and let them cool out. 

If they are going into thermal runaway (overheat), they might burn and or explode, but most likely, what will happen is that the end of the batteries will pop off. 

It’s important to note that a battery explosion is extremely unlikely due to the safety features that modern box mods have; however, there is a minute chance that they might happen, and if they do, you need to be aware of what you should do. 

If you check the batteries and they don’t exhibit any damage but are still too hot to the touch, let them cool out and get a brand new pair since the old batteries are close to reaching the end of their lifespan. 


We hope that with this advice you are able to pinpoint the cause of your heating problem. The most important thing to remember is that if the warmth is coming from the battery section of your device, you should be more careful handling and should take the problem a bit more seriously. 

Most importantly, remember this: If you believe your vape is too hot, do not attempt to troubleshoot by checking it; move it outside your home quickly and away from flammable objects and see if it cools down, and if it cools down, then, and only then, should you tried to troubleshoot the problem.
