A single thunderstorm can instantly fry a PC, TV, router or gaming console, and residential electrical fires linked to lightning cost over $1.2 billion in U.S. property losses in 2021. With climate change driving more frequent and intense storms, protecting your tech before a strike is becoming essential.
FEMA’s simplest recommendation is to unplug every device when a storm approaches. Even a nearby strike can induce a voltage spike that travels through wiring, plumbing or metal in walls, overwhelming circuits and causing permanent damage. Unplugging is cheap and effective.
For longer‑term defense, use surge protectors that meet a minimum 2,000‑joule rating and a clamping voltage under 400 V. Plug major appliances directly into wall outlets—extension cords can overheat. Whole‑home surge‑protective devices installed at the breaker panel, or a licensed lightning‑rod system, shield the entire house. A UPS with battery backup provides both surge filtering and power during outages, though it costs more.
By combining immediate unplugging with the right protective hardware, homeowners can avoid costly repairs and keep their entertainment setups safe, whether they’re at home or away.
