Many electronics require many outlets. For example, a simple desktop computer will require an outlet for the monitor, CPU, speakers, wireless router, modem, printer, and any other gadgets you want to plug in. Home theaters can also require multiple outlets.

While the typical solution is to buy either a surge protector or a power strip, there are important differences between these options to consider. Most surge protectors are also power strips, but power strips are not necessarily surge protectors. You can often find them in the same aisle at the hardware store or general store. But you should know the difference before you buy.

Power strips are basically extension cords with multiple plugs, but surge protectors are designed to protect electronic equipment from electrical surges.

Surge protectors work by diverting excess voltage to the grounding port of an electrical outlet. Without this feature, excess voltage would flow through all connected power lines and cause permanent damage to connected devices.
