What happens if an e-cigarette gets dropped in water?
Leave a message
Of course. Here's a detailed breakdown of what happens when an e-cigarette or vape is dropped in water and what you should do.
The severity of the damage depends on two main factors:
How submerged it was: Was it a quick splash or fully submerged for several seconds?
The device type: A simple, disposable vape pen is different from a complex, expensive mod with removable batteries.
Immediate Effects and Risks
The primary danger is to the battery and the electronic circuitry.
Short Circuit: This is the biggest immediate risk. Water, especially if it contains minerals (like tap water) or is salty (like ocean water), can conduct electricity. When it bridges the wrong connections on the circuit board, it can cause a short circuit. This can:
Fry the internal circuitry, permanently killing the device.
Cause the device to fire erratically or get extremely hot.
In a worst-case scenario, lead to battery failure, thermal runaway, and even a fire or explosion.
Battery Corrosion: Water triggers corrosive chemical reactions inside the lithium-ion battery. This can permanently damage the battery cell, reducing its capacity, causing it to hold less charge, or making it unstable. A damaged battery is a significant safety hazard.
Damage to Components: The tank or pod itself is usually fine and can be dried out. However, the coil (the heating element) will almost certainly be ruined. Water will cause the cotton wicking material inside the coil to swell and the metal coil itself to oxidize (rust) very quickly.
What to Do Immediately (Step-by-Step Guide)
⚠️ SAFETY FIRST: DO NOT TRY TO USE IT OR CHARGE IT. ⚠️
Trying to turn on or charge a water-damaged device is the fastest way to cause a short circuit and a potential battery incident.
Remove it from the water immediately. The less time it's submerged, the better.
Power it down (if possible). If you have a advanced device with buttons, try to turn it off. If it's a simple draw-activated pen, you can't.
Separate the components (if possible).
If it's a device with a removable battery, take the battery out immediately. This is the single most important step to prevent a short circuit. Carefully dry the battery terminals with a paper towel.
Remove the tank or pod from the battery/mod.
Dry the exterior. Thoroughly pat everything down with a dry paper towel or cloth.
Disassemble as much as you can. Take the tank apart (remove the drip tip, glass, coil). Toss the coil-it's not worth saving.
Dry the components.
DO NOT USE A HAIRDRYER OR MICROWAVE. High heat can damage seals, plastic components, and is extremely dangerous for the battery.
The best method is to place the disassembled device and components in a bowl or bag of uncooked rice or silica gel packets. These desiccants will pull moisture out of the air and small spaces. Leave it there for at least 24-48 hours.
Wipe the internal connectors of the battery mod with a cotton swab slightly dampened with isopropyl alcohol (90%+), then dry immediately.
Wait and hope. After at least 24-48 hours, reassemble the device with a new coil. Then, try turning it on.
Will It Work Again?
Disposable Vapes: Almost certainly not. They are sealed units with non-removable batteries. Water will destroy the electronics and battery. It's best to dispose of it safely and get a new one.
Pod Systems & Vape Pens: Maybe. If it was a very brief dip and you dried it out quickly, there's a chance. However, the internal damage may not be apparent and could be a future hazard.
Advanced Mods (with removable batteries): The mod itself might be recoverable if you removed the battery instantly. The tank will be fine after a clean and a new coil. The battery is the biggest concern. If the battery was submerged, it is highly recommended to recycle it safely and replace it. Do not risk using a water-damaged battery.
The Bottom Line
While it's possible to save a device from a quick splash, a fully submerged e-cigarette is often a lost cause due to the high risk of internal damage to the battery and circuits.
Prioritize safety over saving money. If you have any doubts about the device's integrity-especially if it gets hot, makes noise, or behaves strangely after you try to use it-stop immediately and dispose of it properly at a battery recycling center. The risk of battery failure is not worth it.
