Once you have installed a Home Surge Protector, your power strips can still help add a layer of protection for systems like computers or routers. Some customer may choose to keep these for the convenience of turning off a group of lights or for offering battery back-up while a computer shuts down but many of these tasks are now handled via Smart Home features or no longer needed. A Whole Home Surge Protector replaces all of these devices with much more effective protection against power surges. Power strips can add redundancy and further reduce risk if desired.
