Dropped Vape in Water — Will It Explode?

Accidents happen. Maybe your vape slipped out of your pocket into the sink, fell into a puddle, or took an unexpected dive into the toilet. One of the first concerns that comes to mind is: "If I dropped my vape in water, will it explode?" Here's what you need to know about vape safety after water exposure, and what steps to take immediately.

Can a Vape Explode After Being Dropped in Water?

The short answer is: it's highly unlikely—but not impossible. Most modern vapes are built with safety features that prevent immediate combustion. However, water exposure can damage internal components, including the lithium-ion battery. If the battery is compromised and you try to power it on or charge it afterward, there’s a real risk of overheating, short-circuiting, or even fire.

Explosion is rare, but the potential for battery malfunction makes it dangerous to continue using a water-damaged device.

What Happens When a Vape Gets Wet?

When a vape is submerged or even splashed with water, the following risks arise:

• Short-circuiting: Water can bridge electrical connections that should remain separate, causing a short.
• Battery instability: If water reaches the battery, it can corrode or damage it, leading to erratic behavior.
• Malfunctioning chipsets: Regulated mods contain delicate circuits that control wattage, temperature, and safety protections. Water can destroy these components.

Even if the vape seems fine on the outside, internal damage may not be immediately visible.

Immediate Steps to Take

If you’ve dropped your vape in water, follow these steps immediately:

1. Power it off (if possible): If the device is still on, turn it off immediately. If it’s unresponsive, do not attempt to power it on.
2. Remove the battery (if removable): This prevents further current from running through the system and reduces the risk of short-circuiting.
3. Disassemble the device: Separate the tank, pod, or cartridge from the battery section.
4. Dry everything: Use a paper towel to absorb as much moisture as possible. Leave the device in a dry area for at least 48 hours. Some users recommend placing it in a sealed container of dry rice or silica gel to absorb residual moisture.
5. Inspect for signs of damage: Look for corrosion, water in the screen, or an unusual smell. If in doubt, do not attempt to charge or use the vape again.

Should You Try to Use It Again?

No, not until you’re certain it’s safe. Even then, proceed with caution. If your vape has a built-in battery, it's best to replace the device altogether. The cost of a new vape is far less than the risk of a fire or explosion.

If your vape uses an external 18650 or 21700 battery, and the battery was exposed to water, discard the battery immediately. Water-damaged lithium-ion batteries are unstable and not worth the risk.

Preventing Future Accidents

• Use silicone cases or covers for grip and water resistance.
• Avoid vaping near pools, sinks, or open drinks.
• Store your device in a secure, dry pocket or pouch when not in use.

Conclusion

While it’s rare for a vape to explode just from being dropped in water, it’s still a serious hazard if the device is powered on or recharged afterward. Water and electronics never mix, especially when lithium-ion batteries are involved. When in doubt, don’t risk it—replace the device and stay safe.
