Many modern homes have surge protectors build into the WiFi cabinet as preventative measure. If you do not have a WiFi cabinet, it may be worth investing in a surge protector, especially if you have your own modem and router as opposed to one provided from your ISP. Brown outs and other power outages can damage your electronics. As the available voltage goes down, your electronics will begin to overheat as they draw more current. When the power is restored, the sudden spike in voltage could also damage your devices. I use the
Belkin Power Strip Surge Protector and it has served me well. I have my PC, speakers, and monitor all plugged into it. It protects up to 4000 joules and has a reset switch. You can always get something smaller or more compact to better fit your needs. Hope this helped, take care.
