A surge protector shields computers, phones, chargers and other electronics from the voltage spike that can hit when grid power returns after a long term power outage. It keeps the gear you rely on to stay informed and connected working once the lights come back.
A good surge protector shields your electronics from the voltage spike that often arrives when grid power comes back after an outage. Choose one built to absorb repeated hits and tell you when it is worn out.
- Joule rating: Pick a rating of 1,000 joules or more for computers, TVs and chargers.
- Clamping voltage: Select a clamping voltage of 400 volts or lower so less of the spike reaches your gear.
- Outlet count: Count the devices you plan to protect and add two spare outlets for phones and lights.
- Safety listing: Look for a listing from a recognized testing lab so the unit meets a known safety standard.
- Status light: Choose one with a light that shows protection is still active, since a worn unit keeps passing power without guarding it.
- Replacement plan: Swap the unit after a major surge or when the status light goes out.
