The answer to 'surge protector power surge' is that a surge protector can fail to protect your electronics from a power surge. Common causes include lightning strikes, electrical grid issues, or faulty wiring in your home. Symptoms may include your surge protector's indicator light turning off, or your devices not receiving power even when plugged in.
If your surge protector has failed, you'll need to replace it. When shopping for a new one, look for a unit with a high joule rating (at least 1,000 joules) and a UL 1449 safety certification. For severe or recurring surges, you may need to have a whole-home surge protector installed by a licensed electrician.
