What happens if an e-cigarette gets dropped in water?
Leave a message
If an e-cigarette falls into water, it can be permanently damaged, and the most serious risk is the potential for the lithium-ion battery to explode due to water contact. You should never try to use the device again immediately.
The following table explains how water causes different types of damage:
| Component Affected | How Water Causes Damage |
|---|---|
| Lithium-ion Battery | Water can cause a short circuit, leading to rapid overheating, swelling, or explosion. |
| Electronic Circuit Board | Water alters electrical impedance, causing failure. Corrosion from minerals in the water can cause permanent damage over time. |
| Atomizer & Coil | Water can flood the wicking material, preventing proper e-liquid absorption. This can lead to a "dry hit" when powered on, burning the wick and producing harmful chemicals. |
| Internal Connections | In many devices, the atomizer's positive and negative electrodes are not sealed. Water can flow through these gaps into the battery connection socket, causing short circuits and corrosion. |
🚨 Immediate Steps to Take
If your device gets wet, follow these steps in order:
Retrieve it Immediately: The longer it's submerged, the worse the damage.
Power Off Instantly: If it has a button, try to turn it off to cut power.
Remove the Battery (If Possible): For devices with removable batteries, take it out immediately. This is the single most effective way to prevent a short circuit.
Disassemble and Dry:
Separate the tank/pod from the battery/mod.
Gently shake out any visible water.
Do not use heat (like a hairdryer or oven), as this can damage seals and batteries.
Place all components in a dry, absorbent material like uncooked rice or silica gel packets for at least 48-72 hours.
Inspect Before Use:
After drying, check for corrosion (white or green crusty residue) on metal contacts.
Look for any signs of battery swelling.
If you see any damage, do not use the device. Dispose of it properly.
Test Cautiously:
Only attempt to use it if it appears completely dry and undamaged.
Take a short, careful first puff. If it tastes burnt, produces little vapor, or behaves erratically, stop using it immediately.
⚠️ Important Safety Warnings
Never use a wet or damp device. Attempting to power it on while wet is how short circuits and battery failures occur.
Do not charge a wet device. This greatly increases the risk of fire or explosion.
Dispose of it properly if unsure. If the device was fully submerged, was in saltwater, or you are uncertain about its safety, the safest course of action is to dispose of it. Many electronics retailers offer battery recycling.
Be aware of health risks. Using a damaged device can lead to inhaling harmful byproducts from a burnt coil or malfunctioning components.
