The answer to 'difference between surge protector' is that a surge protector is a device that helps protect electronic equipment from sudden spikes in electrical current, while a power strip is simply a device that provides multiple outlets for plugging in multiple devices. Surge protectors have built-in circuitry that detects and diverts excess voltage, while power strips do not have this protective functionality.
Surge protectors are recommended for sensitive electronics like computers, TVs, and home entertainment systems to prevent damage from power surges, which can be caused by lightning strikes, electrical grid issues, or faulty wiring. Power strips are more basic and simply provide additional outlets, but do not offer surge protection.
