What to Do If Your Power Bank Gets Water Damaged? Emergency Steps

Power banks are essential for keeping devices charged on the go. But what happens if a power bank accidentally gets wet? Water damage can cause short circuits, corrosion, and irreversible damage if not treated properly. Knowing the right emergency steps can save the device or at least prevent further harm.

Immediate Step: Turn It Off

The very first thing to do if a power bank gets wet is to immediately disconnect it from any device and turn it off if it has a power button. Keeping it on or attempting to charge it can allow electricity to flow through water, which may lead to short circuits or even fire hazards.1

Remove Excess Water and Dry the Surface

Carefully wipe off any visible water from the exterior with a dry microfiber cloth. Avoid inserting anything into the charging ports as this may push water deeper inside. Gently tap or shake the power bank with the charging port facing downward to help dislodge trapped water without shaking it violently.2

Air Dry in a Well-Ventilated Area

Place the power bank in a dry, well-ventilated spot with good airflow to allow moisture to evaporate naturally. Avoid using hair dryers or heat sources as excessive heat can damage internal components. Using a fan or a dehumidifier to promote air circulation is recommended. Let it dry for at least 24 to 48 hours before attempting to use it again.3

Use Desiccants if Available

If possible, enclose the power bank in a sealed container with silica gel packets to absorb moisture effectively. While the popular rice method is sometimes suggested, it can be less effective and may introduce dust or debris into the ports.4

What to Avoid

• Do not use heat sources like hair dryers or ovens.
• Avoid blowing compressed air into the ports as this can push moisture further inside.
• Do not insert objects like cotton swabs or paper towels into the charging port to avoid damage.
• Do not try to power on the power bank until it is completely dry to prevent short circuits.5

Safety Warning

Water and electricity can be a dangerous combination. If the power bank shows signs of overheating, swelling, or malfunction after drying, stop using it immediately and consult a professional. Continuing to use a damaged power bank can pose fire and electric shock hazards.67

Following these steps can help prevent permanent damage and increase the chances of salvaging a water-damaged power bank.
