Are most surge protector strips fine for protecting electronics?

Yes, if they have actual surge protection. Many cheap “surge protector” strips are just power strips with a fake safety light. Look for a joule rating of 1000+ and a clamping voltage under 400V. For a computer or TV, a $20-30 surge protector from a known brand like Tripp Lite, APC, or Belkin is worth it — don’t trust a $5 strip with anything you’d be sad to lose.
