Is It Safe to Use Electronics After Lightning?
Last updated October 28, 2026
The short answer
What Lightning Does to Electronics
Lightning can send a powerful surge through your home's wiring, even if the strike is not direct. That surge can travel along power lines, phone lines, and cable connections, reaching devices that are plugged in. Surge protectors help, but a direct or nearby strike can overwhelm them, leaving your electronics at risk.
The most obvious signs of surge damage include a burnt smell, visible scorch marks on outlets or cords, or a device that simply will not turn on. Sometimes damage is internal, with no visible clues. If you suspect a surge, unplug everything and wait a few hours before testing devices one at a time.
Check for Water Damage First
Lightning often brings heavy rain, and water may have entered your home through windows, roofs, or foundations. Water and electricity are a dangerous mix. Before you touch any electronic device, check the area for dampness, puddles, or wet carpet. If you find moisture, do not plug anything in.
If your home took on water, the pros can help with water damage inspection to see which areas are affected. They can also assist with structural drying and dehumidification to remove hidden moisture that could later damage electronics or cause mold. Acting quickly reduces the risk.
If storms are common where you live, keep a flashlight and battery-powered radio handy during storm season, just in case you need to unplug everything for a while.
- Look for wet spots near outlets and baseboards
- Check for water stains on ceilings and walls
- Smell for musty odors that suggest hidden moisture
- Feel carpets and rugs for dampness
- Inspect the breaker panel for any tripped switches
When to Unplug Everything
If lightning strikes close to your home, unplug all electronics immediately, including TVs, computers, routers, and even appliances like refrigerators and washers. Do not rely on surge protectors alone. Unplugging is the only sure way to keep a surge from reaching your devices.
Wait until the storm has fully passed and you are sure there is no immediate threat. Then, plug devices back in one at a time, testing each briefly. If a device shows signs of damage, leave it unplugged and consider having a professional inspect it, especially if it contains water-sensitive components.
After a Strike, Inspect the Home
A lightning strike can cause more than just electrical surges. It can spark fires, crack walls, or damage your roof, allowing water to enter. Walk through your home and look for smoke, soot, or water stains. Check the attic and basement for leaks, and inspect the exterior for loose shingles or damaged gutters.
If you find any water intrusion, address it right away. Standing water can quickly damage drywall, flooring, and personal belongings. The pros can perform emergency water extraction and dry out the affected areas. They can also help with drywall repair if the water has soaked through.
Storms can happen any time of year, so staying prepared is wise. Keep a basic emergency kit with flashlights, batteries, and a battery-powered radio in an easy-to-find spot.
- Check smoke detectors and carbon monoxide alarms
- Inspect the electrical panel for burn marks
- Look for cracked window panes or broken seals
- Verify that the sump pump is working
- Test all outlets with a simple plug-in device
What the Pros Can Do for You
If your electronics or home have suffered water damage from the same storm, local water damage pros can help. They can assess the extent of the water intrusion, extract standing water, and set up drying equipment to prevent mold and structural decay. They can also inspect electronics that may have been exposed to moisture.
Electronics restoration specialists may be able to clean and salvage devices that got wet, but that work depends on the severity of the exposure. Always unplug wet electronics and let them dry completely before attempting to use them. If in doubt, consult a professional.
Policies vary, and your insurer decides what is covered.

How long should I wait before using electronics after a lightning storm?
Wait until the storm has completely passed and you have checked for any water damage. If you see wet spots, wait until they are dry. For safety, unplug everything and test devices one at a time after a few hours.
Can a surge protector fully protect my electronics from lightning?
Surge protectors help with minor surges, but a direct or very close lightning strike can overwhelm them. The only sure way to protect electronics is to unplug them during a storm. After a strike, unplugged devices are generally safe to use.
What should I do if my electronics got wet from rain after lightning?
Do not plug them in. Turn them off, unplug them, and remove any batteries. Let them dry in a well-ventilated area for several days. If they were submerged or heavily soaked, consider having a professional inspect them before using again.
