When the weather forecast predicts a storm, the real threat often comes from lightning’s power surge. Even if you’re not directly struck, the energy can travel through your home’s electrical system and overwhelm small kitchen appliances. By unplugging them in advance, you protect both your devices and your safety.
Lightning can generate between 100 million and 1 billion volts, according to the NOAA National Severe Storms Laboratory. Such a sudden spike can overload circuit boards, stress wiring, and in some cases trigger fires. While circuit breakers are designed to trip under overload, the surge can be too fast for them to react, and the breaker contacts may weld shut before they open.
Many homeowners rely on plug‑in surge protectors, but the Association of Home Appliance Manufacturers (AHAM) cautions that these devices are intended for laptops, televisions, and other small electronics—not for household appliances. AHAM experts warn that using a plug‑in protector with appliances can actually cause overheating.

Lightning doesn’t need to strike your home directly to cause harm. Through inductive coupling, the intense electromagnetic field can transfer energy to nearby cables, power lines, and even metal objects acting as antennas. This makes the damage from thunder and lightning far more widespread than many realize.
Because of these risks, the safest strategy is to unplug air fryers, blenders, coffee makers, microwaves, slow cookers, stand mixers, and toasters before a storm arrives. If you’re staying in, keep appliances on a dedicated circuit with a whole‑house surge protector. If you’re away, the same principle applies—unplug everything, secure the outlets, and rest easy.
