Worried about vape explosions? Find out what causes vapes to explode, how common it is, and what you can do to stay safe when using a vape device.
Can Vapes Explode?
Yes, vapes can explode — but it's extremely uncommon. Most incidents happen due to battery failure, particularly in devices that use removable lithium-ion batteries. Explosions typically occur when a battery overheats, short-circuits, or is charged improperly. In nearly every reported case, the fault isn’t with the device itself but with how the battery was handled or maintained.
This is why disposable vapes are considered far lower risk than advanced mods with external battery compartments. That said, any vape with a lithium battery has some level of fire hazard if not used responsibly.
What Causes Vape Explosions?
The most common cause of vape explosions is thermal runaway — when a battery gets too hot and the internal components break down, releasing flammable gases that ignite. This usually happens when a battery is damaged, overcharged, exposed to water, or paired with the wrong charger. Using cheap, unregulated chargers or modifying the vape’s software can also increase the risk.
Pocketing spare batteries without a protective case is another common mistake. Keys, coins, or metal objects can cause the battery terminals to short out, creating sparks or fires.
Are Some Devices Riskier Than Others?
Yes. Mechanical mods — the types without built-in safety features — are riskier than regulated devices with circuit protection. Mods that allow users to build their own coils or adjust power output manually come with more responsibility, and the margin for error is much smaller. If you’re using a device with removable batteries or high-wattage power settings, proper battery safety becomes essential.
Pod systems and disposables, which are sealed units with fixed outputs and built-in protection, are far less likely to malfunction in this way.
How to Prevent a Vape Explosion
To avoid a vape-related fire or explosion, always use the correct charger supplied with your device, never leave it charging unattended, and avoid charging it overnight. If your vape uses removable batteries, buy from reputable brands, store them in plastic cases, and never use damaged or torn battery wraps.
Also, keep your device clean and inspect it regularly for signs of swelling, overheating, or unusual smells. If your vape gets unusually hot during use or charging, stop using it immediately and replace the battery or device.
What to Do If Your Vape Starts Overheating
If you notice your vape getting abnormally hot, stop using it right away. Turn it off, place it on a non-flammable surface, and disconnect it from the charger if plugged in. Avoid touching the battery area directly, and never try to cool it down with water. If the battery is removable, carefully eject it using proper tools and dispose of it at a battery recycling centre.
For sealed systems, you should contact the manufacturer or retailer and discontinue use. Continuing to use an overheating vape puts you and others at risk, even if it doesn’t explode.
Final Word
Vape clouds can and do trigger smoke detectors—especially optical ones—due to the dense particles they release into the air. While vaping doesn’t produce smoke in the traditional sense, the fine mist it creates is enough to fool most standard alarms. To avoid false alarms and unwanted consequences, it’s best to vape only in permitted areas, stay away from detectors, and ensure the space is properly ventilated. Treat vaping indoors with the same caution you would if you were lighting a cigarette—because to most smoke alarms, there’s not much difference.
